Chapter 14 epilogue truth revealed
The work of forensic medicine is not only for solving homicide cases, but forensic medicine is inseparable from the identification of the injuries of the injured in many public security cases and the testing of poisons in anti-drug cases.Especially in some traffic accidents, the role of forensic medicine is even more prominent.Whether it was a traffic accident during his lifetime, or a traffic accident after his death; whether the driver had a traffic accident caused by coercion or coercion; it is even necessary to analyze the driver-passenger relationship in an accident car, as the basic basis for later accident identification and compensation liability .
Therefore, many traffic police departments are also equipped with forensic doctors in the accident handling department.
As the forensic department of the provincial department, it is not only necessary to serve the criminal police, but also to serve the traffic police.Moreover, once a traffic accident scene is surveyed, it is usually a large scene, and only a few or even a dozen lives are lost.
Yanggong County is located in a traffic artery, and there are frequent traffic accidents. We will often rush to Yanggong County to investigate the scene of traffic accidents.But this time, they encountered a difficult traffic accident.
A member of the public heard a loud noise outside the house at four o'clock in the morning.In his sleep, he realized that something might have happened, so he put on his clothes and went out to have a look, and found that a row of trees on the curb opposite his residence had fallen down, and there was still a tire on the road.
The road in front of the gate is the road from the county town to the neighboring counties. The road condition is good and there are few vehicles.There are often some young people here who come to drag racing and go for a ride.On one side of the road is a canal. It is now the flood season, and the water depth is five or six meters.So the masses immediately realized that there might be a traffic accident.Because he didn't have a mobile phone, the crowd ran for a kilometer along the road before finding a passerby who borrowed his mobile phone and dialed 110.
The police and traffic police rushed to the scene one after another and salvaged the scene.After several hours of salvage, a Mercedes-Benz car and four bodies were salvaged from the ditch.
Two of the four deceased were the boss and vice president of a company in the county, and the other two were escort girls of a high-end KTV.The deceased all left the car after the car entered the water, but because of the impact, their self-rescue ability declined, and they drowned in the water one after another. No one was able to swim ashore or persist until the police rescued them.After blood tests, all four were in a state of drunkenness.
The cause of death and the accident have basically been clarified, but because it was drunk driving and the compensation involved, the family members of the four deceased asked the public security organs to find out the driver.The traffic police department retrieved the cameras on the road section, but because of the reflection of the headlights in the dark, all the cameras were unable to record the general physical characteristics of the driver.Therefore, this important task fell on the body of the forensic doctor.
Because the National Day holiday was safe and sound, Lin Tao, Dabao, I and I have not been on a business trip for more than a week, and we couldn't sit still.After receiving the invitation, the three of us agreed and sent a car to set off immediately.
But I didn't expect that accidents would happen one after another.When we were approaching Yanggong County, we received a call from Section Chief Hu.
"It's terrible." Chief Hu said, "The 'June 3rd Project' has been released again!"
"What?" My surprised voice woke Dabao who had fallen asleep in the car. I turned on the handset and said, "It's been almost a month since the first case was committed, and it's been five years since the first case was committed." It's been a month. Who is this person who commits crimes so persistently, and we haven't caught any clues yet?"
"The murderer's method is simple," Chief Hu said. "The simpler the method, the less likely it is to leave clues."
"Is it also a man in his thirties this time?" I said, "Is he also using the same method?"
Chief Hu was silent for a while, and said, "This time it's different. The deceased was a woman, and she didn't have her neck cut and laparotomy."
"Ah?" I said, "Then how can you identify it as the 'June 3 Project'?"
Chief Hu said: "Because the genitals of the previous deceased Liang Fengzhi were in the deceased's pocket. Moreover, one breast of the deceased was cut off."
"Put the organs of the last deceased next to the next one," I said, "this is what the murderer of the 'June 3 Project' did! The reason why he doesn't cut his neck and disembowel him now must be because he knows that we have paid great attention to him. , He doesn’t need to use this eye-catching method to provoke us anymore.”
"Yes, we also analyzed it in this way." Chief Hu said, "The murderer has begun to simplify the killing procedure."
"What can I do?" I said, "I'm on my way to a traffic accident in Yanggong County, and I'm almost there."
"Don't worry." Chief Hu said, "The case of your master Mr. Chen has been completed, and the murderer has been shot dead by the police. Now Mr. Chen is back and personally supervises the case."
"That's good." I said, "Wait for me, I'll come as soon as I go! Never let this demon kill anyone again!"
My evaluation of myself is that the "adaptation threshold" is relatively wide. I can swallow salty or light vegetables, and I can go out when I dress hot or cold.Going to the murder scene, even if it’s waxing corpses or looking at giants, as long as I can stabilize my thoughts and think, within five minutes, my brain will be able to ignore the pungent stench.
Therefore, after answering the phone, although my thoughts were tied up by the "June 3 Project", as soon as I arrived at the scene of this traffic accident, my mind was full of people, cars, and roads, and the picture of the "June 3 Project" was completely forgotten. Two clean.
At the scene of the accident, the vehicle and the body have been removed, and the police and wire repair workers are negotiating beside the cordon.The accident caused a power pole to collapse and torn wires scattered across the ground.Nearby street lights and some residents' homes suffered a large-scale power outage, and the power company's telephones blew up.
In order to allow the power company to restore power as soon as possible, we immediately started survey work.
The trees on the side of the road have fallen, but they are not broken, and the bark of the small trees lying on the ground has been scraped off.At the end of the fallen tree is a broken and fallen utility pole.
"Look, the bushes by the river have fallen," Dabao said. "This is where the vehicles enter the water."
I measured the utility pole with a tape measure, and said: "There are silver-gray paint flakes on the utility pole, which should be attached after the vehicle was hit. These paint flakes are relatively high, and should be higher than the height of a small car. "
"What do you mean?" Lin Tao asked.
I said: "The vehicle sped up after uprooting trees all the way. Although the chassis of the vehicle may be lifted by the trees, it is impossible for the vehicle to fly due to the weight of the vehicle and the weight of four people. Since the impact point can reach such a height, it means The vehicle may have overturned."
"You mean the vehicle hit the utility pole while it was on its side?" Lin Tao said.
I nodded, took off my gloves, and said, "The situation at the scene cannot be artificially disguised. This is undoubtedly a traffic accident."
The vehicle has been pulled to a garage for inspection, not restoration.The car has been crashed to the current level, and there is no need to repair it.
It was a silver-gray Mercedes-Benz sedan. The front bumper had come off, but the hood was still intact.
"Is this car quite crashworthy?" Dabao said.
I shook my head and said, "The trees at the scene were very thin and did not break, indicating that the impact force was not very strong. Because the soil on the curb was soft, the trees fell down after being hit, and the vehicles were actually shoveling on the side. tree, while galloping. There was no serious frontal impact. You can see that the airbags in the car didn't deploy."
I walked around the car and stopped in the trunk of the car.The trunk of the vehicle was deflated and completely deformed.
I used a ruler to measure the depression above the trunk, and said: "This semicircular depression has a diameter consistent with the utility pole, indicating that the vehicle has overturned when it drove to the utility pole. hit a power pole."
"Because of the collision, the vehicle's forward route changed," Lin Tao said, "and it fell into the water. If it wasn't for this collision, the vehicle would just shovel the tree forward, and it might still stop eventually. People don't die either."
I nod in approval.
Dabao noticed a reflective sticker on the tail of the car that said "Transformers".
Dabao said, "Hehe."
"I believe that the traffic police department can also easily determine the overturning process, impact process and water entry process of the vehicle." I said, "But who is the driver, we need our forensic doctors."
"Are you sure?" Lin Tao shook with the bumps of the vehicle.
I said: "Whether the forensic doctor can deduce the driver is not absolute, it depends on the conditions. If there is no injury on the body, God can't judge it. Once there are some characteristic injuries, it can be identified. So I am also very concerned now. perturbed."
The place we rushed to was the place I was more resistant to—the hospital mortuary, and it was the mortuary of the largest hospital in the county.
The morgue is full of ice coffins, and there are all kinds of corpses lying in them.
I rubbed my nose, put on my dissecting suit, and walked over to the four mortuary beds in the center of the mortuary, where the bodies of the four victims who died in the accident were.
"Take off the dead man's clothes first." I said.
Several forensic doctors hurriedly took off all the clothes on the corpse. I saw at a glance that there was no open wound on any of the deceased, and even obvious subcutaneous bleeding was not found.
"It's over." Dabao said, "There is no damage, how can I judge?"
I calmly looked at the limbs of the deceased one by one, and said: "No, there are injuries, very slight, I think we have hope to get the correct answer."
"There was no serious damage, which means that the vehicle did not have a serious frontal collision," Lin Tao said. "This can confirm our determination of the accident process."
I nodded and asked the traffic police next to me, "Does the family agree to the autopsy?"
The traffic policeman said, "I don't agree."
"Disagree?" I said, "Didn't the family members ask to find out the driver?"
The traffic police said: "The family asked the public security organ to find out who the driver was, but they did not agree to an autopsy."
I know that after many accidents, the reasons put forward by the family members are just to ask for compensation, but because of the influence of traditional Chinese thinking, they are unwilling to let their relatives be stabbed after death.
So, I said, "Then let's try."
Although only the examination of the corpse table greatly reduces our work intensity, but because we cannot see the tissue changes inside the corpse, it means that there is a lot less basis for inference.Fortunately, we were blessed in this case. After just three hours of post-mortem examination, I had a definite conclusion.
Having reached my conclusions, I requested to meet the families of the four deceased.
"Are you sure?" Director Zhou in charge of traffic police in Yanggong County said.He just came back from the provincial office, and there was such a big accident, the management responsibility cannot be shirked, after he was criticized, he returned to the county in disgrace.He was suspicious of my meeting with the family members of the deceased rashly, because a little carelessness might lead to petitions, and at that time, his responsibility was even greater.In fact, he didn't know. After the autopsy, I remembered the fifth case of the "June 3 Project" hundreds of kilometers away, and the fifth victim who died unjustly.I was really anxious to go back.
But now Director Zhou has lingering fears about the hearts of the people in the provincial department. After receiving my firm answer, he can't say anything more. He can only deploy obediently and make appointments with the family members of the deceased on the phone.
"After on-site investigation and vehicle inspection, we have basically determined the process of the accident." I pointed to the photos on the slide and said.
"Stop talking nonsense, we need to know who is driving the car." A man reprimanded.
"Ah...my son...you died so badly..." A woman burst into tears suddenly, causing arguing, scolding, and crying in the conference room, making the scene chaotic for a while.It took a long time for Director Zhou to bring tea and water to comfort him, and it took him a long time to restore the atmosphere to calm again.
I was secretly glad that Lin Tao had already processed the photos of the corpse in advance, so as not to cause riots again.
"Well, let's talk about the damage now." I coughed dryly to relieve the embarrassment of being interrupted just now, "Through the autopsy, we determined that the dead male No. 1 was the driver through damage analysis."
"Nonsense!" The man just now interrupted me, "The car belongs to my son, so you think he's the driver? That's how you handle the case? What do you need to do? Do you want to eat?"
"Then you mean that the car belongs to your son, so your son can't be the driver?" This time it angered me, "Then who do you say is the driver?"
The family members of the other deceased stood in my camp, and everyone began to criticize him, so he sat back down.
"The damage distribution pattern of male corpse No. 1 is glass scratches on the left side and hard object contusions on the right side. It means that when the accident happened, he had broken glass on the left side and smooth hard objects on the right side. According to the vehicle inspection, only the driver's The location is OK, there is a window on the left side, gears and handbrake on the right side. The bruise on the right side of the waist of the No. 1 male corpse indicates that there is a blunt object in this position. The side waist corresponds to the seat belt buckle."
I finished speaking in one breath, paused, and found that the father of deceased No. 1 did not jump out to object, so I continued: "The inner side of both ankles of male corpse No. 1 has scratches, which means that there is a hard object between his feet. The surface is relatively rough. We checked the whole car, and only the driver had a brake plate between his feet. This injury is different from the other deceased. In addition, there was a scratch mark on his left knee trousers. The inspection of the vehicle revealed that there was a hood switch on the corresponding part of the driver's left knee, with a sharp corner that could scratch clothing, and there were no hard objects in other parts of the vehicle that conformed to the shape."
I just finished speaking, except for the driver's father, the other family members of the deceased nodded in approval.And the driver's father also seemed to be a little short of words, but he still asked persistently: "Then...then tell me where the other people are sitting, and you can analyze it. If there is no doubt, I will accept it. "
I thought to myself, fortunately everyone's injuries have their own characteristics, otherwise I would have been asked.I smiled slightly and said, "Female deceased No. 1 was the co-pilot. Her injury is characterized by contusions on the lower part of her upper arms, which is consistent with friction with a flat object. The lower sides of her upper arms can touch a flat object, and only the co-pilot is in the position. "
"Then she won't be the driver?"
"No. Let's imagine that if the driver's armpits touched the dashboard, then the steering wheel would definitely be pressed against the chest, and the chest of the deceased was not injured. In addition, among the four deceased, only the No. 1 female body was not injured. The glass was scratched. Only the front windshield and the right front window glass of the vehicle were not broken, and the others were broken. This shows that she is sitting in the co-pilot."
Seeing that no one answered, I went on to say: "The No. 2 male deceased was sitting behind the co-pilot because the glass was scratched on his right side, and the collar showed signs of being torn off. The collar was still on his right side. There was a strangle mark on the side of the neck, indicating that the left corner of the clothes was under force, indicating that there was someone on his left. In addition, there was a huge hematoma on his right temple, indicating that there was a hard object on the right side. I wanted to say before that the accident process was The vehicle had a process of overturning to the right, so his head may have hit the door frame at this time."
There was another faint sobbing sound in the meeting room, and I quickly finished my sentence: "The rest is the No. 2 female corpse, she is sitting behind the driver. There is a glass scratch on her right hand palm, indicating that the vehicle is overturning to the right." During the process, she supported herself with her hand on the broken right side window glass, so she would scratch it. If she was sitting in the seat behind the co-pilot, she would not be far enough to support the right side window with her hand .In addition, a fingernail on her right hand was broken, which should have been caused by her pulling the clothes of the dead man No. 2 sitting on her right when the vehicle rushed up the curb."
There was silence in the conference room.
I added: "I'm done."
The venue was quiet for a while, and several family members agreed and left.The driver's father opened his mouth, but couldn't say anything, and left silently.
Director Zhou watched several family members leave, and said excitedly: "Old Qin, your analysis is the most exciting and convincing analysis I have ever heard in the years I have been a traffic police officer! It is so exciting!"
I was a little flattered by the compliment, picked up my bag and said modestly, "It's just that the conditions of the case are good, and now we're going back."
The analysis of the accident made me feel good about myself, so as soon as I got back to the provincial office, I couldn't wait to go to the master's office.Firstly, I hadn't seen Master show up for a few months, and I really missed him; secondly, I must report the accident to Master in full, so that Master knows that his apprentice will not lose face if he goes to any department to handle the case.
But as soon as he entered the master's office, he saw the gloomy face of the master.
I smiled and said, "Master, I did it today..."
"You are suspended from work today." Master said.
"It's a beautiful case." I didn't realize it, and finished what I just said.
"Suspension?" Lin Tao was the first to react.
My whole body suddenly became numb, and I said, "Master, that, who is suspended?"
Master stared at me with burning eyes.
I looked back at Dabao who was stunned and Lin Tao who was stunned, and then looked at the steadfast Master. I felt that Monk Zhanger was a little confused, so I mustered up the courage to ask: "I am suspended? What happened to me?"
Master stared at me and said, "The reason for the suspension is now kept secret. You don't have to go to work from tomorrow. You can stay at home honestly and accept summons at any time."
"Summon?" My brain turned around quickly, thinking that my old Qin Xing was sitting upright, and he had never done anything wrong. Did I make any mistakes?Still need to summon so serious?
I am Master's most beloved disciple. In the end, he couldn't hold back my pleading. With a sullen face, he took out a stack of photos from the drawer, threw them to me, and said, "Look, do you know her?"
The woman in the photo is in a white gauze top, black short skirt, and lace stockings. She is lying on the ground, pale and pale. She died of blood loss, and her right chest was soaked in blood.
I suddenly remembered the fifth victim of the "June 3 Project" mentioned by Section Chief Hu, the deceased whose breasts were cut off by the murderer.
Seeing the materials of the "June 3rd Project", I was a little angry, but I still didn't overwhelm the doubts in my heart. I read through the stack of photos carefully. The last one is a photo of the deceased's life before his death. The girl in the photo is smiling. , Pure and cute, but the face is definitely unfamiliar.
I shook my head and said, "I don't know."
Master suddenly changed the subject: "What are you doing during Eleventh?"
Seeing that Master's complexion had improved, I rolled my eyes and said with a playful smile, "I've been at home with my wife, thinking about how to have a son."
"Your DNA is on the deceased's underwear." The master hit the nail on the head, "Did you do bad things when Ling Dang was just pregnant?"
My whole body became numb again: "What? I, I, I, I haven't gone out for a few days, how is this possible?"
The DNA of each forensic doctor will be entered into the DNA database, so as to prevent contamination during the dissection and material collection, so my DNA is also stored in the database.I did not participate in the examination of the fifth corpse, so it cannot be contamination, then my DNA was found on the deceased, it is only possible that I had contact with the deceased.
"Mr. Chen, you don't suspect that the series of cases involving the eleventh finger was done by Lao Qin, do you?" Lin Tao watched from the sidelines.
I looked at Lin Tao blankly, feeling grievance, anger, doubt, and entanglement, all kinds of emotions weighed on my heart, and I couldn't say a word. I just looked straight at Master, and Master also looked at me.
After a stalemate for a while, the master said: "The method of murder in this case was poisoning and choking. In the first three cases, there was a laparotomy. The laparotomy was very professional, and it was a tongue-out method commonly used by forensic doctors. The special case team had been wondering whether there was any The insiders are making trouble, but they didn’t expect to find your DNA through a carpet test on the fifth corpse, Liu Cuicui.”
"What is it?" Lin Tao said, "Hair? Dander?"
The master was silent for a while, then said, "It's the spot."
I just recovered some thoughts and was about to speak when I was stunned by this sudden sentence.
"I...I...I, she...she...she." I stuttered suddenly.
"The amount of suspicious spots is very small, as if it had been swabbed. Like the previous 'Yuntai case', the seminal spot pre-test was positive, but no sperm was detected." Master said, "But the DNA is yours."
"But...but I went to the hospital for an examination, and I'm normal." I said, "I have a diagnosis certificate."
"No." Dabao's rare firmness suddenly appeared on Dabao's face, "I don't believe that Lao Qin did it. The case where the son of the university professor died, we were working on the case together before, and he didn't have time to commit the crime."
"I also read this information." Master said, "It is because of this case, otherwise they would have arrested you long ago. You have never lied to me. You told me that in these cases, you have Haven't been involved?"
"No!" I exclaimed.
"Okay! I believe in you, so I will tell you everything. Then you have to be calm now." Master said, "The task force will not wrong you, but you can no longer participate in the work during this period, go to the archives to see Looking at previous case materials is not a waste of time."
Where is the mood to look at the archives?
I was accompanied by stacks of closed case files and whispers over the walls of the archives.How absurd is it that I, a forensic doctor who has repeatedly solved murder cases, is now a suspect in the murder case?
I took the photo of the deceased woman Liu Cuicui and looked at it again and again, trying not to avoid it, reminding myself if I had something to do with her before?But after watching it for a whole day, I firmly told myself that I must not know her.
It was getting late, I didn't go home, I didn't know how to go home, how to tell Bell about this matter.In the empty archives room, I began to look through the archives slowly, trying to use my super strong "adaptation threshold" to pull myself back from the mixed thoughts.
Lin Tao and Dabao suddenly opened the door and walked in.
Dabao said sadly: "Today we went to steal the materials of five cases of the 'June 3 Project', and then copied them out for you. You should study them carefully."
"This is stolen." Lin Tao looked back at the door and said, "If the task force finds out, we will die. This is a violation of discipline."
"Well," Dabao nodded vigorously, "We don't want to come here to look at the files like you."
I was moved to look at these two brothers.In my current situation, apart from Master, I am afraid that these two are the only people who trust me the most.I said, "I'm going to sleep here for the past few nights. If you have nothing to do at night, come and study the case with me."
Watching the two leave quietly, my heart feels like I have been knocked down. If it weren't for the trust and support of these people, would I collapse now?
The strong "adaptation threshold" has played its role again.The case files of various abnormal deaths quickly pulled me into a state where there were no distracting thoughts. I even started to calculate the approximate number of abnormal deaths and homicides in the province every year, as well as the proportion of various cases.
I don't know if I don't see it, but I was shocked when I saw it. In a province with a population of tens of millions, there are seven to eight thousand abnormal deaths every year.Among them, traffic accidents accounted for a part of the proportion, followed by suicide and sudden death, and then some disaster accidents.Among them, the suicide file looks the most interesting. The forensic doctor needs to use various damage patterns or traces to rule out the possibility of homicide.
For example, in one case, just looking at the photos, there was a huge incision on the neck of the deceased, no matter how you looked at it, it felt the same as the throat of the deceased in the "June 3 Project", but the forensic doctor judged it to be suicide.The reason was that the area around the deceased was covered with splattered blood, without any blank space.If someone cut her throat beside her, when the blood splashed in the air, it would be blocked by the murderer's body, thus forming a blood-stained blank area.There is no blank area, which means that there is no tangible human body around the deceased.Moreover, the collar of the deceased's high-necked sweater was turned down, and it was absolutely impossible to return the collar if someone killed someone.
The forensic doctors of the provincial department generally only investigate difficult murder cases, so they have much less investigation of all kinds of abnormal deaths than grassroots forensic doctors, and they have much less experience.I finally understood Master's good intentions, and let me use this period of time to check for omissions and make up for vacancies.
In addition to disasters, accidents and suicides, there are still some unsolved murder cases.Since the Ministry of Public Security announced that murder cases must be solved this year, most of the energy of the criminal police department has been devoted to solving murder cases, and the rate of solving murder cases is also among the best in the world, so I have seen very few murder cases that have not been solved, and some of them have been clearly identified. It's just that the suspect hasn't arrived yet.But there are also some murders with almost no clues, so I guess the task force just gave up.
I quickly went through this year's file from the back to the front, and the time was close to two o'clock in the morning.
Many horror novels regard two o'clock in the morning as a node of a horror event, and some weird things usually happen at this time.After I read the watch, I thought so, and then got goose bumps all over my body.
The file in front of me is an abandoned baby case that happened at the beginning of this year, which happened in Longpan City.To be precise, it is the event that the body was abandoned after the baby died of illness.The photo shows a roadside trash can with a swaddle on one side.There is a loose cord on the outside of the swaddle, which came off because the cloth surface was slippery.
I turned to the next page, and there was a picture of the baby's body.There was no injury on the corpse, and the skin of the snout, nose and neck was intact, but the corpse was cyanotic, which is likely to be the death of a disease.
But none of this attracted me. Instead, it was the marks on the baby's thighs that attracted me.
I raised my watch subconsciously again, and the hour hand happened to point to two o'clock in the morning.
During this weird time, weird things still happened after all, but sitting next to the filing cabinet, I didn't feel any fear, instead, I was extremely excited.
Because the trace I found is very likely to become the most favorable clue to solve the "June 3 Project".
There are many strangle marks on both sides of the baby's thighs, which were formed after death.Explain that after the baby died, the person who abandoned him wanted to use a string to fix his legs so that he could be thrown away easily.However, because the soft tissue of the thigh is rich and elastic, the bandages fell off several times, forming a characteristic soft tissue indentation.
In addition, the baby had postmortem sharp scratches on the outer thigh.This is a cut mark on the outside of the legs with a knife, but due to various possible reasons such as the abandonment of the baby's hands, it only scratched the skin of the legs and did not hurt the muscles.
"Why cut the thighs?" I said to myself in the file room alone, and the room echoed me, "Cutting and binding!"
I think the baby abandoner wants to use this method to fix the baby's legs because they have failed to bind them many times, so that they can be easily discarded.This method is exactly the same as the binding method of the mutilated corpses in the previous "June 3rd Project".Could it be done by one person?
I couldn't wait to flip through the entire file.
The forensic examiner for this incident was Zou Shuwen, an old forensic doctor in Longpan City. He retired two months after handling the case, so the other forensic doctors did not know the details of the case. No one can think of this abandoned baby case.
Forensic doctor Zou conducted a partial autopsy on the corpse and conducted a pathological examination on the baby's heart.The result of the pathological examination report was: congenital tricuspid valve downshift deformity.Tricuspid valve depression is a rare congenital heart malformation.In this disease, the tricuspid valve shifts to the right ventricle, mainly due to the downward movement of the septal and posterior leaflets, which are often attached to the right ventricular wall near the apex rather than the fibrous ring of the tricuspid valve. The position of the anterior leaflet is mostly normal. Therefore, the right ventricle is divided into two chambers. The wall of the ventricle above the deformed valve is thin, and it is connected with the right atrium to form a large chamber. The chambers, including the apex and outflow tract, are called the "functional right ventricle" and perform the same functions as the normal right ventricle, but with relatively smaller chambers.Often accompanied by atrial septal defect, ventricular septal defect, patent ductus arteriosus, pulmonary artery stenosis or atresia.Increased right atrial pressure can occur. At this time, if there is an atrial septal defect or an open foramen ovale, it can lead to right-to-left shunt and cyanosis.
Because other causes of death can be ruled out, although most children with this disease died around the age of ten, combined with the baby's cyanosis, the forensic doctor judged that the deceased died of this congenital heart disease without effective rescue.
This is an incident of abandoning the dead body of a sick baby, not a homicide.After some investigations, the unit handling the case did not find any relevant clues, so the case was closed like this.
None of this is critical.The key point is that the baby's swaddling clothes are kept in the physical evidence room of the Longpan City Public Security Bureau without DNA testing.
I was so excited that I picked up the phone and wanted to find Lin Tao and Dabao, but thinking that they were quite tired today, they must have fallen asleep, and I will tell them the good news tomorrow.
The reason for my excitement is not because my grievances are about to be snowed, but because this mountain that weighs on the hearts of all the police officers in the task force has finally revealed the dawn in the process of flipping through the files inadvertently this time.
Because of exhaustion, I unknowingly fell asleep lying on the row of chairs in the file room.
When I woke up, I called Dabao and Lin Tao, and told them respectively what I found from looking through the files last night.Lin Tao couldn't hide his excitement, but Dabao asked blankly, "What do you mean?"
Lin Tao and Dabao have rushed to the "June 3rd Project" task force, reported the discovery to the task force in a timely manner, and made a request to extract relevant evidence of the original abandoned baby case and send it to the provincial department for DNA testing in time.
After delivering the physical evidence, Lin Tao and Dabao rushed to the archives room and looked through the archives with me.
"Even if we have the suspect's DNA, so what?" Dabao said, "Longpan City has a population of 10 million, how can we investigate? Normally, it is impossible to use DNA for investigation in a small town with thousands of people, let alone Not to mention a provincial capital city?"
"It is impossible to use DNA as the basis for screening." I said, "DNA can only be used as a basis for screening. The cost of a DNA sample test is more than 100 yuan."
"So," Dabao said, "what we need to solve now is how to quickly find the suspect's hiding place or find out where he often goes."
"I think it's more reliable to describe the characteristics of criminals first," Lin Tao said.
I nodded and said, "I agree! At least this person is psychopathic, ruthless, and probably has been dealt with by the public security organs, so he provoked the police."
Lin Tao said: "I see, I have a personal enmity with you, so I pretended to be a forensic doctor, and got your DNA. But if your kid is really okay, how did he get your DNA?"
I blushed and said, "I'm definitely going to sit upright and have a clear conscience!"
"I once argued with Forensic Doctor Han whether the murderer was a man or a woman." Dabao said as if thinking hard, "Now I agree that the murderer is a woman."
"Oh?" I said, "Then tell me, is there any basis for it?"
Dabao said: "What Han's forensic doctor said before makes sense. The murderer had the movement of dismembering the corpse, but the slashing was not strong, and it didn't seem like a man did it. In addition, in every case, poisoning was first performed before killing. This method is very similar to It's a woman's way."
"Aren't you still talking about the basis? You didn't agree with Han Fayi's opinion at first, but now you do?" I asked.
"But in the past two days, I have thought a lot, especially you once told us that when looking at a series of cases, we must connect each case together." Dabao said, "An important connection of this series of cases is the first four cases. The dead were all men."
I fell into deep thought, and Lin Tao said: "But the last one is a woman, so this can't be regarded as a relationship condition."
Dabao said: "Think about it, who can easily trick the other party into drinking poisonous wine or water? They are either acquaintances or seduction. The four deceased have no connection with each other. In the past few months, The main investigation direction of the investigators is whether the social relations of these people are intersected. No connection has been found so far, which means that they are not familiar with each other. Then the possibility of acquaintances committing the crime is ruled out, the most likely It's seduction!"
I patted the table: "Dabao is usually dizzy, but I agree with his analysis! It's just that the last deceased was a woman, which is not easy to explain."
Dabao took out a stack of documents from his bag and said, "This is the latest investigation result. The last person who died was a homosexual!"
Both Lin Tao and I were stunned. This investigation is indeed the best basis for confirming Dabao's theory.
Dabao continued: "To sum up, the person who can easily trick men and homosexual women into drinking poisoned alcohol is most likely a woman!"
"Then why did the murderer start killing men and then women?" I asked, "Is she trying to prevent us from discovering this linking factor?"
Lin Tao said: "This possibility cannot be ruled out. Of course, it is also possible that her sexual orientation changed suddenly."
"So, what should we do next?" Dabao was a little tired after analyzing so much in one breath.
我揉了揉太阳穴，说：“你们知道不知道，女性同性恋聚集的酒吧有哪些？”
“怎么着？”林涛说，“你这是想守株待兔吗？酒吧里那么多人，你去哪里找啊？”
“说的也是，”我说，“但是我觉得如果我们框定出一个大的范围，在这个范围内所有的酒吧、夜总会什么的，都去盯一下，说不准还就真能找到撞上树的兔子。”
“等等，”大宝说，“咱们捋一捋。第一，你怎么框定范围？第二，你怎么知道谁是凶手？”
我摇摇头，说：“这个我也不确定。但是我想，如果真给我们碰上了，总能发现一些端倪吧？别忘了，她想栽赃我，我总能看得出一些破绽吧。”
“好吧，好吧。”林涛说，“我也相信这一点。既然栽赃你，肯定是和你有一些瓜葛的，比如你曾经抛弃过的纯情小女孩什么的。”
我再次涨红了脸说：“没有的事！我和铃铛是初恋！”
“你俩别调情了。”大宝说，“第一个问题你还没有回答我呢，怎么框定范围？龙番市方圆六千多平方公里，一千万人口，你怎么框定？”
我微微一笑，拿出一个圆规，说：“你忘记了？前不久，我去学习了一个冷门学科——犯罪地图学。这个学科在国外很热门，但是国内很多人认为是迷信。我准备来试一试它到底管不管用。”
“犯罪地图学？”大宝说，“好像听你说过。”
我说：“有刑侦专家认为，系列犯罪的发生，都是围绕着凶手主要活动地带来进行的，然后向外扩张。只要你能找出前几起案件的发生地点，然后框定范围的圆心，就是凶手主要的活动地带。”
“这个确实有点儿玄乎，可靠吗？”林涛说。
我说：“死马当活马医了。”
“你说前几起案件的发案地，”大宝说，“那你准备用抛尸地点？”
我皱眉想了想，说：“如果凶手有车，抛尸可以是随意性的，所以不准，那么就以几名死者最后出现的地点来作为发案地好了，看看它们的中心点是哪里。”
我们三人拿出一张龙番地图，然后翻开几起案件调查资料，逐一进行标注。
“孟祥平是在这个医院失踪，在这里。方将在这个宾馆失踪，在这里。程小梁住学校附近，也是在学校遇害的，在这里。梁峰志失踪的地方在这里。”大宝用红笔在地图上做了标记，说，“最后一名死者刘翠翠要不要也算上？”
我点点头，拿过大宝手中的笔，说道：“根据你们给我的资料，刘翠翠的遇害地点是在她的出租屋里，就是这个叫青年人小区的地方。”说完，我在地图上画了个圈。这五起案件的发生地点和调查情况，我早已熟记于心。
我用圆规把几个点连接了起来，是个歪歪扭扭的椭圆形，我在椭圆形的中央，用蓝笔画了个圈，说：“你们看看，这是什么地方？”
“三七五四街区！”林涛叫道，“这里是个酒吧、夜总会、KTV的聚集点。真被你猜到了！”
我笑了笑说：“我也坚信，犯罪地图学的存在，必然有它的道理，一点儿也不迷信！这样看，凶手很有可能是通过色诱的方式，骗取被害人的信任，然后择地杀人。”
“我有点儿奇怪，”林涛说，“当初调查几名死者的时候，对酒吧、夜总会应该是重点调查的，这里的录像应该都调取了吧？怎么会没有发现？”
大宝说：“这个我知道。视频组就十几个人，我有个同学在里面，他前几天还在和我诉苦呢。当时他们调回来的硬盘放了满满一办公室。全市那么多有视频监控的地方，他们十几个人慢慢看。加之凶手作案都是晚上，视频大多不清楚，死者也没有穿着很显眼的衣服。所以啊，要么他们现在还没有看到这个区域的监控，要么就是看到了也没有发现毫无特征的死者踪迹。”
“这个完全可以理解。”我说，“他们又没用犯罪地图学，不一定会先看这个区域的监控。而且，我们办案都知道，那些监控的画面，有几张能用啊？看脸根本就不可能，除非人穿着特别有特征的衣服。”
大宝说：“说到这里，我又有想法了。你们看啊，前四名男子都是单身男性，有来龙番进修的医生，有来龙番出差的老板和律师，还有纨绔子弟。总体上说，他们都处于容易产生艳遇想法的状况。最后一名死者是女性同性恋，自然也不言而喻。我觉得我们的推断非常正确。”
“我们今晚就去守株待兔？”我说，“凶手割了最后一名死者的组织，肯定还是想继续作案的。”
“好哇！”林涛说，“这个街区，美女如云啊，守不到兔子，也可以看看云彩。”
大宝说：“可是，我们现在一点儿抓手都没有，你确定在那里可以找得到凶手？你不是孙悟空，哪来的火眼金睛？”
大宝一句话就像是一根针，把我这个刚刚吹起来的气球戳破了。是啊，没有任何线索，真的能找得到凶手吗？
我这个被戳破了的气球不说话了，场面迅速冷了下来。就在这时，大宝放在桌子上的手机响了起来。
“喂？”大宝看见是专案侦查员的来电，一把抓起手机，接通了。
“DNA检验结果出来了。”侦查员说，“襁褓上检出两人的DNA，其中一个是婴儿本身。”
虽然是弃婴案件，但是根据有关规定，当初法医也取了婴儿的血，并且录入了DNA系统。
“另外那人的呢？”大宝急着问。
侦查员说：“另外的，是一个女性的DNA，经判断，和婴儿有亲缘关系。说白了，另外一个人应该是婴儿的母亲。”
“库里比对了吗？”大宝问，“有没有头绪？”
侦查员在那边沉默了一会儿，说：“没有。”
“看来，咱们还得去守株待兔！”我笑着拍了拍大宝的肩膀，说，“加油！”
我们坐在韩亮新买的克鲁兹里，车子停在三七五四街区的入口处。这里灯红酒绿，穿着新潮的男男女女在我们这些“大叔”平时睡觉的时间里，走进了街区。
“我们真是被时代潮流拍在沙滩上的人啊。”大宝感慨道，“这么晚了，龙番居然还有这么热闹的地方。”
在车里坐了不到一个小时，大宝的鼾声就响了起来。
我递给韩亮、林涛一支烟，我们摇下车窗，点燃。彼此无语。
这个时间是酒吧最热闹的时间，却也是宅男宅女们熟睡的时间，所以街区外面也看不到什么人。只有那刺眼的霓虹灯照射在车里，让人无眠。
不一会儿，大宝忽然冒出一句：“四个四！我们打八了吧？”
“什么意思？”我笑着说。
韩亮说：“他最近学会了一种扑克，叫掼蛋，玩得老上瘾了。”
“也就是说，他在说梦话？”我说。
“他喜欢说梦话你不知道吗？”林涛笑。
我说：“何止是说梦话？他还梦游呢？上次梦游找解剖室，没吓坏我。”
我们的笑声刚落，街区口开始有三三两两、东倒西歪的男女出现。
“散场了。”我坐直了身子。
“人家不叫散场，”林涛说，“你以为是看电影啊？”
人流越来越庞大，我瞪着眼睛，想在人群中找到一丝讯息。我抬腕看了看表，又快到凌晨两点了，连续两天短睡眠，让我此时有了一些困意。
慢慢地，人走完了，我们没有发现任何可疑的线索。
“看来我们这个办法不行。”林涛说，“守株待兔，这就是历史上的一个笑话嘛。我们得想想其他办法，至少得掌握一点儿嫌疑人的特征吧。”
“等等，”我制止了正在打火准备返航的林涛，说，“我怎么听见有人在叫一个词儿？”
“什么？”林涛把车窗摇开，竖着耳朵听。
一个尖锐的女声穿过开启的车窗进入我们的车内。
“池子！池子！”
我全身的寒毛都立了起来。
街区的入口处，一个身穿金色短裙、黑丝袜的清瘦女子出现在我们的视野。一个女子跑过来和她说了几句话后离开，她于是独自往街区外面走。
和其他东倒西歪的男女不同的是，她显得异常清醒。她掏出手机看了看，然后甩了甩齐肩长发，像是叹了口气，独自一人向远处走去，茕茕孑立。
她看手机的时候，手机的亮光照亮了她的脸庞，美丽俊秀。
“有没有觉得这个池子听起来特别耳熟？”我激动万分地说。
林涛皱起眉头，说：“何止是耳熟，这个女人也很眼熟啊！我知道她是谁了。”
“你说。”我盯着车窗外的女人。
“水良的妻子。”林涛一边说，一边打醒了熟睡中的大宝。
水良是“云泰案”的凶手，被判处死刑，已经执行完毕。我们在搜查水良家的时候，见过他的妻子一面，他的妻子还像鬼一样和我说了一句话。而这个引起我们注意的叫声“池子”，到现在还是个谜。为什么这个女人出现的地方，就会有“池子”？
“对！是她！”我仿佛醍醐灌顶，“她当初说过要好好配合我，原来是要杀人作案挑衅我！”
“当初她说要配合你，我以为她看上你了要勾引你来着。”林涛的笑话一点儿也不好笑，他接着说，“不过，你的DNA她怎么会有？你们不会……”
“怎么可能！”我涨红了脸，“我问心无愧！”
“女性作案，受过刺激所以变态，和你有仇，和警方有仇。”林涛说，“她完全符合我们之前推断的所有条件！”
“抓人啊！”大宝抹去口角的口水，不知从哪里拿出一副手铐，“还愣着做什么？”
“你哪来的手铐？”我笑着问。这时候的笑，是舒心的笑，我看见了破案的曙光。
“我在战训队啊，队员都发单警装备的。”大宝伸手就去开车门。
我一把拉住大宝，说：“没搞错吧？你是法医！你是验尸的！你能抓人吗？怎么着？学了两天战训队的科目，就以为自己是侦查员了？”
“都是人民警察。”大宝说，“关键时刻我们也得上啊！”
“别急，”我说，“如果是她干的，她绝对跑不了，相信我。”
“下一步，我们需要密取她的DNA吗？”林涛说。
我摇摇头，说：“不用，我们悄悄跟着她，看她住哪儿就足够了。这个女人不简单，如果现在取她的DNA，一是不合证据提取程序，二是容易打草惊蛇，得不偿失。”
“那你怎么知道弃婴襁褓的DNA是她的？”林涛说。
我说：“我有办法，走吧！”
女人住在街区附近的一个小院落里。从外面看，这个院子不大，但是是独门独户。我们目送女人走进院子后，便悄然离开。
这一夜，我睡得特别熟。
第二天一早，我就来到了DNA实验室。我拉住忙得团团转的DNA实验室主任郑大姐，说：“郑大姐，不管你现在有多忙，得先帮我一个忙。”
郑大姐瞪着眼睛看着我，说：“你不是被停职了吗？”
“我是被冤枉的。”我一边说，一边把郑大姐拉到办公室，说，“有个简单的活儿。当初'云泰案'，水良落网以后，有没有提取他的DNA样本？”
“当然，”郑大姐点头说，“所有嫌疑人抓来第一件事就是提取样本。”
“昨天你们不是做了一个弃婴襁褓上的DNA吗？”我说，“我现在想知道这对母子和水良的DNA能不能比出亲缘关系。”
“你是说，那个弃婴就是水良的儿子？”郑大姐说，“那他家也太惨了吧。”
不一会儿，身穿白大褂的郑大姐从数据分析室里走了出来，说：“对上了，水良、弃婴以及那个女子，是一家三口。”
大宝在旁边反应了过来：“哦，你这是间接确认本案的嫌疑人就是水良的妻子啊。”
“啥也别说了，”我说，“赶紧把这些情况通报专案组，对嫌疑人布控。”
“六三专案”的影响太大了，专案组的压力可想而知。在得知这一可靠信息后，专案组立即组织了精干力量对女子的住处进行了布控，并且趁女子外出之际，对她的小院以及小院里停着的一辆甲壳虫轿车进行了搜查。当侦查人员从甲壳虫狭小的后备厢里拎出一个桶时，现场有位女警忍不住发出了一声惊呼。桶底放着一个塑料袋，里面正是一块疑似乳房的人体软组织！
DNA图谱从机器里慢慢打印出来，郑大姐撕下图谱，用尺子比画了一下，说：“在嫌疑人院落和车里提取的可疑斑迹是人血，经过DNA比对，系孟祥平和方将的血迹。”塑料袋里的软组织，确证是属于刘翠翠的。
此言一出，DNA室里一片欢腾。
这座压在专案组每名民警心头数月之久的大山终于给推倒了。
而此时，我仍在档案室里看档案。看档案，也有瘾。
下午，当女子回到住处的时候，发现院子里站着两名荷枪实弹的警察，她转身想跑，却发现已经遁地无门了，她的身后站着几名便衣。
她随后整了整衣衫和头发，伸出双手，微微地笑了一下，说：“不成功则成仁，我早就准备好有今天了。”
“你没有成功，也不会成仁。”林涛目光炯炯地望着她，“恶魔是要下地狱的。”
没有民警愿意审讯这个女子，因为他们实在无法把眼前这个时髦、靓丽的女子和几个月来连杀五人、手段残忍变态的恶魔联系在一起。他们觉得审讯工作无从下手。
而这名女子则淡淡地说道：“让秦科长来审问我，不然我什么也不说。”
侦查员说：“行。”
