Chapter 24 chapter 2

Within ten minutes, the disheveled Onion sat on the chair where Li Dazui was sitting just now, and tightened the gray down jacket on his body. Carrot spoke first: "Old Yang, they are all from the village, and I won't talk to you about those useless things. The case of Hupanlou is too big. These comrades are all from the province. They must be investigated. The truth will come to light. So, if you know something, say it early and strive for the initiative." "I... I didn't do anything, and I don't know anything." Onion blinked and narrowed his eyes. Carrot was still talking, but Chu Tianying pulled his arm.

For the next ten minutes, the entire interrogation room was silent, and all eyes were fixed on Onion, like a group of cats looking at a mouse that had shrunk to a corner and had nowhere to escape. With his head down, Onion felt his neck getting heavier and heavier, and bead-sized beads of sweat appeared on his forehead.Finally, he rolled his eyelids, and seeing those police officers still staring at him intently, he couldn't help but whisper, "I really don't know anything..." Snapped! Chu Tianying slapped the table hard, and then shouted, "Remove his stool!" In an instant, the stool under Onion's buttocks was kicked off.Several criminal policemen stuck him to the wall like a bag, and he shouted in fright: "I confess! I confess!"

"It was about eight o'clock in the evening on October 24th. I guessed that there would be no customers. I was about to close the store and go to bed early. Unexpectedly, a middle-aged man who appeared to be in his forties came in and said that he would Accommodation. He has a thin and long yellow face, and he looks fierce. When asked if he eats or not, and how long he stays, he always ignores the answer. Ask him for his ID card, but he forgets to say it. I agreed. I opened a room for him, and he closed the door inside so that no one would be disturbed. At around nine o’clock, he suddenly changed into a black coat and carried Go out with a canvas bag...According to the old rules of opening a shop, if there are customers outside, the headlights in this hall cannot be turned off overnight. I feel sorry for the electricity bill, so I keep looking at the watch. About half past ten, he came back , his yellow face turned pale, he rushed upstairs as if he had taken something, and then rushed downstairs, leaving without even taking the deposit." Onion said, "Early the next morning, I heard that the lakeside building was released. I thought it might be the fault of this person..."

Li Kuohai was furious, "Why didn't you report to us right away?!" "I... I wanted to chat with Director Hu, but I didn't dare. It's all my fault. If I insist on asking for the ID card, I won't let him live. Maybe I have nothing to do here." Onion With a sad face. "Did you tidy up that man's room later?" Chu Tianying asked. "No... I checked, and he didn't leave anything behind." Chu Tianying immediately ordered: "Old Li, you bring some criminal skills, and immediately rush to that room with Yang Cong. In addition to looking for physical evidence, pay special attention to extracting fingerprints, hair and other evidence. Then, take him to the criminal suspect's office." People puzzle, add a big beard after it is done, let Li Dazui identify it, see if it is the person who booked the lakeside building!"

Li Kuohai and the others went out with the onion. Carrot saw that Chu Tianying kept squeezing the Jingming acupoint with his index finger and thumb. Knowing that he was tired, he found him a room with a single bed and let him go in to rest. . Chu Tianying fell asleep as soon as her head touched the pillow. He was sleeping soundly, when suddenly the phone in his trouser pocket buzzed and vibrated, he picked it up and saw that it was Lei Rong calling, so he answered it quickly. "Director Lei." Chu Tianying apologized, "It's so late and I haven't rested yet." On the other end of the microphone, Lei Rong smiled faintly, "Just after leaving the autopsy room, I did a re-examination of the Hupanlou body overnight, and I have to go back to Beijing tomorrow, and I have another case to deal with."

"What's the result?" Chu Tianying asked, she could hear some tension in her voice. "The fundamental causes of death of Li Jialiang and Meng Ruhu are relatively clear, both were caused by violence. But I noticed that Meng Ruhu's back of the head was not only severely hit by an ashtray, but also had a basic wound." Chu Tianying was taken aback, "What is a base injury?" "Simply put, it's a previous wound that was covered up by the ashtray." "I understand." Chu Tianying said, "You mean, Meng Ruhu had already been hit once before being injured by the ashtray?"

"Yes." Lei Rong said, "This wound is quite serious. It should be hit with an iron rod or iron tongs, which caused the occipital bone to rupture. I think this blow has killed Meng Ruhu, and the ashtray The smashing blow was probably intentionally made by the murderer in order to cover up the underlying injuries." In the dark room, a chill passed over Chu Tianying's body. Who is the murderer?Why be so cruel?Why cover up that first blow? Lei Rong continued on the microphone: "The other four deceased had obvious inner ear bleeding. This is a rather strange thing, because their direct cause of death should be myocardial infarction, which rarely causes Ear damage. In addition, Meng Ruhu and Li Jialiang also suffered from inner ear edema."

"Could it be poisoning? Don't poisoned people bleed from all seven orifices?" "That's only found in novels." Lei Rong said seriously, "The so-called poisoning is actually chemical damage. Most poisons act on the blood circulation or nervous system, causing functional or organic diseases in the body. Leading to death, the common symptoms are nausea, coma, vomiting, convulsions, and rarely bleeding from the seven orifices.” "Then what would cause their ear damage?" Chu Tianying was even more puzzled. "Generally speaking, perforation of the eardrum or fracture of the skull base can easily lead to ear bleeding. Improper ear removal and boxing injuries are also more common." Lei Rong said, "But the ear bleeding of the four corpses was obviously not caused by the above reasons. What is the reason, I still can't tell. I have already sliced ​​the relevant organ tissue, and will use a tissue slicer and a microscope for further examination after returning to Beijing."

Ear damage, ear damage, ear damage... He walked up and down the entire lakeside building, and never asked about the conference room at all. The guest rooms and restaurants were viewed more casually, but the ktv private rooms were carefully inspected, and he even tried the stereo and microphone... Li Dazui's words suddenly appeared in his mind. "I understand! I understand!" Chu Tianying shouted excitedly, "Director Lei, do you think it might be caused by noise? For example, the murderer locked those people in a closed ktv room and used a remote control device to Turn on the stereo, and a huge volume is released from the stereo, piercing the eardrums of these people, causing them to die suddenly from myocardial infarction.”

Lei Rong said calmly: "Theoretically, what you said is feasible. A noise of 190 decibels is enough to kill a person. However, when a person is exposed to high-decibel noise, they generally have the intention of blocking their ears or avoiding the sound source." Behavior. For example, in that private room, at least you can break the window to escape, but they didn’t. Besides, there is really such a loud sound, can no one hear it in the whole Hulingzi Township? You know, 150 decibels is already the sound of artillery gone." Chu Tianying stood blankly in the dark for a long time before saying anything, "Director Lei, I have another idea, you may find it ridiculous..."

"When discussing scientific issues, it is the most absurd to have no ideas." Lei Rong said gently, "Speak." Chu Tianying said: "Right now, public opinion is putting enormous pressure on Jianyi Company. There are rumors that the Hupanlou tragedy was caused by those six people operating a five-element yin and yang mirror in a private room. The death caused by radiation seems absurd. Do you... do you think this is possible?" Lei Rong pondered for a moment and said: "I haven't conducted experiments, so I can't jump to conclusions, but from experience, I think it's impossible. The root cause of radiation-induced death is the release of energy in human tissues, causing cell death or damage, leading to Body lesions or even cancer. If the radiation is of moderate intensity, such as leukemia, the incubation period from exposure to onset is two years, and the incubation period for tumors is five years. If it is acute exposure, it means receiving a large dose in a short period of time Irradiation can cause acute radiation sickness, manifested as massive hemorrhage, bacterial infection, etc., and death within a few days—I don’t know if you understand, like the death in the lakeside building that occurs within a few hours, if it is Caused by radiation, unless a nuclear reactor is placed in the ktv room." This way does not work. Chu Tianying asked again: "Can you arrange the death time of these six people?" "Based on the current level of forensic medical examination, the estimation of the time of death can only be accurate to the hour at most." Lei Rong said, "But from the results of the autopsy, I have this inference: First, all six people were killed by someone. Because their autopsies showed different degrees of ear damage, four of them died immediately, and the other two, Li Jialiang and Meng Ruhu, probably did not die immediately due to differences in physique. For some reason, they fought -" Chu Tianying asked: "Director Lei, the palm prints and fingerprints extracted from the handle of the knife have proved that Li Jialiang was indeed killed by Meng Ruhu. So, is there such a possibility? During the fight, what did Li Jialiang do? Guy, when Meng Ruhu stabbed him with a knife, he also gave Meng Ruhu a slap, and then he was afraid that Meng Ruhu would not die, so he picked up an ashtray and hit him on the back of the head, and then Li Jialiang fell down beside the gate and died?" Lei Rong said: "I have three points to prove that your guess is not true: first, the stabbing of Li Jialiang immediately caused the rupture of the abdominal aorta and hemorrhage in the abdominal cavity. Second, you said what murder weapon Li Jialiang used, but in the crime scene report, there is no mention of any other murder weapon; third, Li Jialiang's body and Meng Ruhu's body are far away from each other at the scene, if it is really like what you said The situation should be that the bodies of the two people are in a state of wrestling together - with their fatal injuries, both of them were killed by one blow, and there is no possibility of taking another half step." "So, Director Lei, is my following idea valid?" Chu Tianying took a rough breath, "After those four people were killed, Meng Ruhu killed Li Jialiang. Then, just as he stared blankly at the fallen Li Jialiang in the pool of blood, in the dark and dead KTV room, a man appeared behind Meng Ruhu, holding an iron rod, with his arms raised high..." "Tianying." Lei Rong's voice was trembling, and there was a bitter smile, "It's four o'clock in the morning, and I'm standing alone in the aisle outside the autopsy room. Even if I've been a forensic doctor for many years, you don't have to do that. Test my guts." Chu Tianying said in a low voice, "I'm sorry." Lei Rong was quiet for a while, and said: "Tianying, I don't know if your idea is valid or not. Because judging from the results of the autopsy and the investigation of the crime scene, there must be a seventh person in the ktv room, and he undoubtedly killed it himself. Meng Ruhu died, but what method did he use so that he didn’t die immediately like the other six people? After killing Meng Ruhu, how did he escape from the private room with the doors and windows locked? I can’t figure it out.” After hanging up the phone, Chu Tianying sat by the bed for a long, long time.The night was thick as ink, he clearly felt that he was also locked in a secret room, surrounded by walls, no matter how he walked, he would hit a wall...
