Chapter 7 Chapter two

"There's no good evidence that Ed was guilty of killing, of course, although he had a motive." After another interrogation of Ed, Bob said to me, "Dude, anything new?" "Not yet, the fingerprint analysis has not been obtained yet, and it is very troublesome." I said with some headaches.I know Bob is in a hurry, because according to regulations, we can only detain Ed for forty-eight hours. If there is no progress tomorrow, we have to release him.Of course, the result of this is that we may let the murderer go. "I think he can be interrogated again." Bob said, frowning.

I shrugged my shoulders, noncommittal, in such cases, time is a relatively important weight.Maybe there will be some new progress tomorrow.We just want to get some information from Ed that will help the case, and we want to ask him if there are any clues that he hasn't explained, and if he knows who might be the murderer of her wife. However, the result of the interrogation the next day surprised everyone.Ed Anlovic's response ticked us off like a ticking time bomb, as he admitted that he was the real murderer - which is kind of incredible - in such a short time that Ed admits to killing lost his wife Shirley.

In this case, we have to figure out Ed's motives.Ed told us that he hit Shirley that night and said he hit her so hard that Shirley fell to the ground and fell silent.He thought Shirley was dead and was frightened, so he quickly picked her up and put her on the car.At that time, the three children were too scared to come out because they hid in the room and did not see their mother being beaten to death by their father.Then Ed drove to the playground and threw Shirley's body there. In fact, Ed did know part of the case.For example, he knew where the dead bodies were dumped.However, this does not explain anything, and Ed's daughter is very dissatisfied with the police's approach.The news of Ed's guilty plea quickly reached their ears, and we had to deliver the news to them.However, the three little girls didn't believe it at all. The eldest daughter, Nancy, even asked us directly in the police station why we thought her father killed her mother.

Nancy asked us to learn more about her father's personality, such as: When Ed was in charge of pouring concrete on the construction site, he would not allow the slightest mistake of his own.She said that Ed was very kind to them, and she knew that her father could not be the murderer!She made us believe what she said, even though she was only 14 years old. What this 14-year-old girl said is not simple. I think she is at least much more mature than children of the same age. In order not to judge a good person, we interrogated Ed again the next day, but he again admitted that he was the murderer, and then refused to communicate in any form.

"I killed my wife Shirley, you don't need to investigate, I did it!" Ed repeated.Another day later, a large but striking headline appeared in the Wernepick free newspaper. It read: WIFE-MULTIPLAYING HUMAN SUED. How could this case be closed so quickly?In fact, no one in the police station believed it was true, but no one could explain why.This murder case can also be said to be the easiest but strangest case to be solved since I worked as a forensic doctor.Therefore, I can't tell whether I am happy or uneasy in my heart. Ed Anlovic was charged with second-degree murder.In section 231 of the eighth part of the Canadian Criminal Code, "Endangerment to person and reputation", murder is divided into first-degree murder and second-degree murder. First-degree murder includes all planned and intentional murders and certain other murders (such as murder police officers, prison staff, or any other person authorized to work in a prison, provided that such personnel are on duty); second-degree murder is any murder other than first-degree murder.

Now, Ed, who admitted to murdering his wife, has been temporarily detained, and we are still looking for suspicious points in this case. For example: Part of Ed's confession does not match the murder scene.Ed said he was very drunk that night, so his memory may not be very clear.But I do know that researchers at the University of Toronto in Canada tested students who drank and did not drink before exams and found that the students who drank forgot what they had prepared for the exam, and that even a little alcohol could reduce what people remembered. new knowledge. The question is whether Ed was drinking too much that night. If he drank a lot of alcohol at that time, then a large amount or excessive intake of alcohol would have an inhibitory effect on the nervous system of his brain. Lowe became unresponsive, including losing control of his hearing, vision, language, hands and feet. He said that he had a headache, dizziness, excitement and irritability after drinking a little wine that night, and eventually vomited and wanted to sleep.

Due to the excitement of alcohol and the loss of self-control, ordinary drunks behave arbitrarily and recklessly, do not listen to other people's advice, and do some abnormal things, such as talking crazy, fighting, fighting, throwing things, or even losing their minds and hurting people. Ed said in his confession that he drank and drove and could still remember driving behind a large park.The impact of alcohol on the driver at this time should be: blurred vision, Ed would have no sense of direction or hallucinations in his consciousness at the time, he could not concentrate on driving the car to the playground behind the big park, Then throw and smash the corpses.You know, when he threw away his wife who lived with him, would he really do it like this?

Ed also said in his affidavit that he was driving sober at the time.According to our analysis, under the anesthesia of alcohol, people's tactile ability will be reduced. As for the hands and feet, it is difficult to control the steering wheel, joystick, accelerator, brake and other operating systems, which will cause Ed's hands and feet to be uncoordinated. Ed also said that when he drove the car to the playground behind the large park, he began throwing and smashing the bodies.From our analysis and judgment, we know that the judgment ability of the person who drinks too much will decline. Because the drinker is unresponsive, he has difficulty in understanding the road conditions, including distance, speed, signal lights, surrounding scenery, and ability to avoid. Accurate judgment.Ed was in a state of fatigue, he could drive erratically, and would sometimes appear to fall asleep at the wheel while driving, so how did he manage to get behind the big park?

I told Bob all these doubts, and I also told him one of my thoughts.I said, "I think Shirley's bites and bruises warrant further investigation, but I need some help." "So, who do you think can help us?" Bob said while sipping his coffee.While eager to close the case as quickly as possible, he was never irresponsible. "Richard Munro, he is a geologist. I need his assistance. Show him the file of this case." Richard Munro, a geologist with Wernipick Police Department, has studied all kinds of soil in the world, including concrete.Here's how I thought about it, a 55-pound concrete slab was found near Shirley's body.And many Canadians keep concrete slabs in the trunk of their cars for added traction in the snow.In Ed's trunk, criminal investigators also found some concrete debris, and his trunk was full of concrete debris.

At first I was very excited about this discovery, but do these debris match the murder weapon?Could the murder weapon fit in his trunk?The process of verifying these few issues was tedious because hundreds of pieces of debris, all very small, were found in Ed's car.The surface of the murder weapon was rough and cracked, so it was as if we were doing a jigsaw puzzle to find the pieces that would fit. When Richard arrived, he worked on the pieces for a day and finally told me with a shrug that he had found nothing, no matching pieces. Next, police sent photos of the bite wounds on Shirley's body to David Sweet, a dentist who works for the Vancouver judiciary.

Ed's dentures were sent for analysis.After a good pair of fixed dentures are repaired, if you want to prolong its use time, you should pay attention to protecting its two major parts, one is the basic part and the other is the restoration part.The basic part refers to the abutment teeth, which are the basis for carrying dentures. The most harmful things to it are periodontal inflammation and occlusal forces that exceed the load capacity of the abutment teeth.We have now encountered a difficult question: Is a person with dentures on the upper and lower teeth strong enough to bite off human tissue? Due to years of use, Ed's dentures have occlusal marks, which shows that his dentures fit well, and they are removable dentures.Movable inlaid teeth are also called movable bridges. It is made of stainless steel wire as a clasp, and then the elastic clasp of stainless steel wire is used to cover the front and rear real teeth, and the base and denture are made of plastic.This kind of dentures can be taken and worn by patients by themselves, and can be taken off and cleaned after meals and before going to bed, which is more hygienic.It can also be removed for repair and adjustment after wearing the teeth, no need to remake. But Ed said he still feels a foreign body sensation after wearing this set of dentures.This is the biggest problem with movable dentures. When Eddie wears such dentures, he feels a severe foreign body sensation, which will affect his ability to speak.When we recalled the previous two interrogations of Ed, we found that Ed's speech pronunciation was a bit inaccurate. He said that his throat was not feeling well these days.Now it seems that something called foreign body sensation is at work. Maybe the occlusal force of Ed's dentures can really generate enough force to tear the muscle tissue on Shirley's body?The bite force of an adult is generally 80 kilograms, while the opening and closing degree of the mouth of cats is about 60 degrees, such as saber-toothed tigers can reach 100 degrees. We also know that the bite force of a male lion is 400 kilograms. So Dr. Sweet performed a sizing analysis in which he measured the width and curvature of Ed's dentures to see if they would fit Shirley's bite.I think Ed's teeth are relatively small. Although his mouth is big, when he smiles, we will find that he smiles more reservedly. The results came out, and Dr. Sweet could find little resemblance between the two. I'm kind of thankful that we all became suspicious of Ed and arrested him.But now everyone is thinking, is this Ed in front of him the real murderer? I re-examined Shirley's body and carefully swabbed the bite site with a cotton ball for possible forensic evidence.I wrapped the swab in a moistened filter paper and the paper turned white.This is a very effective test for the presence of saliva.The filter paper test can use a capillary dropper to "drop" the sample on the filter paper to "spot".The next step is to determine the blood type of saliva.At present, forensic science has adopted an advanced new technology when testing saliva, which allows us to measure the blood type of saliva.Its basic method is to adsorb known antigens or antibodies on the surface of a polystyrene micro-reaction plate, so that the enzyme-labeled antigen-antibody reaction can be clearly displayed, and then wash away the free components in the reaction by washing to get the final result. I coated the wells in the dish with antibodies to various blood types and put samples of saliva in them.In the incubator, the saliva sample will attach to the corresponding blood type antibodies. Type A saliva attaches to type A antibodies. O-type saliva will attach to O-type antibodies, and so on. After enzyme-linked immunosorbent assay, the murderer's blood type is B type. This doesn't match Ed's blood type, the saliva we took from the victim's chest swab was type B, and Ed, who has type A blood, would never have left that type of saliva. This shows that Ed did not kill anyone, we caught the wrong person, and Ed was not the murderer the police were looking for at all.We know that Ed was wronged, he was wronged. Ed, the suspect accused of killing his wife, was released due to insufficient evidence.After Ed heard the news, he didn't express any surprise about it. Someone asked him how he felt?He said he didn't want to say anything.Someone asked him, are you happy to be released?Ed said, no comment.All of this, in Ed's view, has passed, and he must go back home immediately, and the three children are waiting for him to go back and take care of them.He continues to be responsible for two of the children, because one of the children is fourteen years old, which is beyond the twelve-year-old age requirement for child custody. But why did Ed plead guilty?We can't find a good reason to explain it in this matter, so we have to recall the previous interrogation of Ed.At that time, the detectives interrogated him and asked him a lot of questions like: "Did you fight with your wife last night?" He replied, "Maybe." They continued to press him and asked him: "Did you Hit her?" He said: "Maybe." These "maybe", or "possible" words lack a certain ability to judge, and Ed drank a lot of alcohol on the night of the crime, which may be Temporary memory loss that occurs after drinking alcohol is also called memory disruption.Because alcohol interferes with the nerve conduction process of memory formation, once the memory interruption is over, it will enter the sober period. At this time, the person concerned will suddenly remember that many, many bad things happened last night, such as cursing or beating people , and even killing people or doing some other things that harm society and human beings.People who are alcoholics in particular will then feel remorse. These people will often cry bitterly, and some will cry out, as if they have a lot of grievances in their hearts and need to vent it.They will imagine the terrible things they have done during the memory interruption period, and some will confess.These are all normal phenomena in my opinion. If Ed has been drinking excessively for a long time, then this incident should be a reflection of his special psychological state, which belongs to chronic alcoholism, which will eventually manifest as chronic alcoholism syndrome.This is a variety of physical and mental disorders that appear in the experience of long-term alcohol abuse, and it can even cause irreversible pathological damage, such as liver function damage or multiple cirrhosis, as well as peripheral neuritis, central nervous system degeneration, or brain damage. atrophy etc. We usually make such judgments for people who drink too much.In addition, alcohol abuse can also cause great damage to many organ systems in the human body. It has been confirmed that alcoholism can cause severe arrhythmia, congestive heart failure, heart thrombosis, cardiomyopathy, myocardial infarction, high blood pressure, and thrombocytopenia. increase in number etc. Ed was innocent and the police had to reopen the investigation.So, who should go into that prison after he gets released from prison?The murderer who actually killed Ed's wife is still at large.
