Evidence hunting forensic 4 unsolved case code

After coaxing Luo Jianan away, Qi Ming cleaned up the medical waste, washed his hands and sat in front of the computer, opened the rescue records and autopsy reports sent by Lin Dong, and quickly browsed them.The speed at which he turned the pages amazed Zhou He on the side, and whispered a gesture of "I can't even keep up" to Gao Ren.Lin Dong was not surprised at all, he got used to it naturally, and the standardized data had already formed a habitual thinking in his brain, as if he could pick out the unreasonable things at a glance when he read the interrogation records.

All the names in the data were blacked out, which made Lin Dong sigh that Xia Yonghui was meticulous enough and followed the rules enough.

About 15 minutes later, Qi Ming looked away from the computer screen and asked, "The deceased died of craniocerebral injury, and the autopsy conclusion is all right. What are you looking for?"

Lin Dong immediately asked, "When did the hematoma form?"

"It is impossible to judge. Depending on the individual's physique, the degree of injury, and the location, the bleeding can be fast or slow. Some people will cause severe intracranial hematoma within a few minutes after being injured, and some people will take two to three days. Therefore, the head The post-trauma observation period is 72 hours."

Qi Ming paused for a moment, and added: "And according to the symptoms of the deceased before admission, it can be basically judged that the hematoma occurred in the detention center. Headache, vomiting, and coma are all typical symptoms of craniocerebral injury."

Lin Dong bowed and held the mouse, slid to the page of the autopsy report, pointed to a line of words and asked, "But the skull is not fractured, why is there such a serious internal injury?"

What Tan Xiaoguang has always advocated is that the interrogation room has an anti-collision layer, and a few knocks will not kill people.In fact, he also had the same doubts. In the interrogation room, there were many suspects throwing up and down, and no one had knocked his head to cause internal bleeding.

"According to the records, the deceased had a long history of drug abuse. Drugs can harden the walls of blood vessels and make them very fragile." Qi Ming took Lin Dong's hand, swiped the mouse wheel to turn the page, and turned to the witness testimony page with blacked-out names: "Look, this witness said that the suspect grabbed the right side of the deceased's head and pushed it, causing the deceased's left temple to hit the crash barrier, but here—" He continued to slide forward, to the autopsy report. Part, "there was a contusion on the left side, and the hematoma was formed on the right side, which indicated that the subdural hemorrhage of the deceased was caused by the secondary brain injury caused by the concussion of the brain tissue caused by the impact, and was caused by inertia. Although the extra-detected splenic hemorrhage was not the cause of death, his liver was damaged due to long-term drug use, and his blood coagulation function was low. If there was no brain damage and he left it alone, he might have died from this.”

Withdrawing the hand held by Qi Ming, Lin Dong stood with his arms folded, frowning.In this way, Tan Xiaoguang really didn't hit too hard, and it was only Zhou Jiandong who couldn't help hitting.Of course, Tan Xiaoguang's act of beating someone violated discipline. As an anti-drug policeman, he shouldn't ignore the hidden dangers of drug addicts, but under extreme anger, he lost his normal ability to judge.However, just like An Guanjiao said, Zhou Jiandong was a scumbag who would not regret [-] deaths. Tan Xiaoguang's punishment, at least in the eyes of other police officers, would inevitably be as desolate as a rabbit's death and a fox's death.

Seeing that he was silent, Qi Ming raised his hand to other people in the office, indicating to leave a private space for himself and Lin Dong. After the room was cleared, he asked, "What exactly do you want me to investigate?"

"This is the case of Tan Xiaoguang. The violent interrogation resulted in the death of Zhou Jiandong, the criminal who shot Ou Fengqi." Lin Dong said frankly, "Later, Tan Xiaoguang found out that a man named Mai Changsui had worked in the hospital when Zhou Jiandong was admitted to the hospital. , worked as a cleaner, and after he was imprisoned, Mai Changsui disappeared, and when the police announced the killing of 'Tan Xiaoguang', he appeared again, so Tan Xiaoguang concluded that Zhou Jiandong's death was related to Mai Changsui .”

"..."

Qi Ming was a little confused when multiple names appeared repeatedly.He didn't remember who Tan Xiaoguang was, it sounded familiar, but he couldn't remember why.It seemed to be related to Zhuang Yu, and it seemed that he had fought with Luo Jianan before.He has a high IQ because he has a high IQ, so he can't remember people's names. It's a flaw. Except for the few people who often deal with in the bureau, he has given them nicknames for easy memory.

Knowing that he couldn't remember the names of people, Lin Dong simply used ABC to refer to each person: "In short, A beat C, C died in the hospital where B worked, A went to jail, and B hid, so A thought B responsible for C's death."

Now Qi Ming finally understood, pondered for a moment, and confirmed: "You want me to help you see if B has a chance to do anything in the hospital, that's what you mean."

You don’t need to go around in circles when you talk to smart people. Lin Dong listened to the words, but just halfway through, he heard Qi Ming categorically say: "It can be said that it is impossible. Have you been to the emergency room? There are people coming and going, a cleaner There should be no chance to start with patients under special care who are being rescued."

Lin Dong disagreed: "This case happened more than ten years ago. At that time, the medical system was more relaxed than it is now. I did go to the emergency room. I saw that after the vital signs temporarily stabilized, no one would care if the curtain was drawn and I lay there." A human patient."

Hearing what he said, Qi Ming immediately slid the picture back to the part of the emergency rescue record, read it carefully again, and suddenly said: "Indeed, the deceased died before the decompressive craniectomy. It was left in the room for several hours."

"Huh? Why?"

"Blood oxygen saturation can't go up." Qi Ming narrowed his eyes slightly as he spoke, and said to himself, "But it shouldn't be... the blood oxygen saturation has already been raised during the first round of rescue...why does it keep falling?" Woolen cloth……"

Then Lin Dong listened to him chattering about medicines, oxygen, heartbeat, blood pressure, blood oxygen and other recorded values, and said "that's right" "what's wrong" "shouldn't be" "lungs are okay too" "Words like that.This kind of situation is relatively rare. If Qi Ming is not sure about some things, then there may be a real problem.

"Could it be that B injected some medicine into the infusion tube?" He tried to help Qi Ming expand his thinking.

Qi Ming said casually: "There is no problem in the toxicology test. The drug metabolism doses in the heart blood, liver, and urine are all in line with the hospital's drug administration records. I just finished the calculation."

"..."

Lin Dong felt that he had a little understanding of Tang Zhexue's feelings when he faced Du Haiwei—professional crushing.But what should be mentioned has to be mentioned. Failure is the mother of success. Proving that you are wrong is also the only way to find the truth: "A shot of air?"

Qi Ming continued to make a nasal voice of denial: "Well, the autopsy found no air embolism in the heart, lungs or brain."

"Extract the oxygen tube?" Lin Dong felt that he was about to run out of water.

"Impossible, then the machine will report—"

Qi Ming suddenly paused as he spoke, swiped forward a few pages, stared at the string of data in the rescue record, read and read again and again, then took a blank copy paper and wrote calculations on it.Lin Dong leaned forward and looked at it, feeling a little relieved—he could understand what Qi Ming wrote, which was to calculate the oxygen supply and output per unit time according to the instrument numbers on the rescue record.

"No." A few minutes later, Qi Ming raised his pen and concluded, "The oxygen parameters of the blood oxygen and ventilator do not match."

"Huh?" Lin Dong was taken aback, a glimmer of light flashed in his eyes, "Someone tampered with the ventilator?"

"The machine can't move, but the pipeline can." Qi Ming took out his mobile phone and searched for a few pictures, and then showed it to Lin Dong, "Look, this is the oxygen supply system on the wall of the emergency room. There are three pipelines and one oxygen tube , a compressed air tube, and a vacuum tube. The oxygen tube and the compressed air tube should be connected to the ventilator respectively to supply oxygen to the patient. The vacuum tube is used to suck sputum to avoid blocking the respiratory tract. Now the oxygen parameters of the blood oxygen and the ventilator are not consistent. , which indicates that the pipe may be reversed."

With the feeling of dawn breaking through the fog, Lin Dong felt his heart beating faster: "Man-made?"

"Yes, this is connected by a nurse. When I was an intern in the hospital, something like this happened once. The nurse connected the compressed air tube and the oxygen tube in reverse, and the patient's blood oxygen saturation could not be raised. The doctor increased the oxygen supply to [-]%, but it didn’t work.” Qi Ming said while tapping the rescue record on the screen, “I remember clearly here, the doctor in charge of C also adjusted the ratio of oxygen and compressed air several times. Therefore, if someone firmly believes that C did not simply die from Tan...Tan...cough, A's violent interrogation, then it can be considered that C was dragged to death because he lost the best timing for surgery."

The chaotic thoughts became clearer, Lin Dong silently digested Qi Ming's professional advice, and raised a practical question: "So, is it possible for a cleaner to master this skill?"

"Okay, if he goes in and out of the emergency room every day, just watch the nurse operate it a few times, it's nothing technical." Qi Ming said while showing him the pictures he just found on his phone, "Also, Didn’t you say it was more than ten years ago? At that time, the bayonet ports of the three ports were the same, and they were only distinguished by color. That’s why careless nurses occasionally connected the tubes backwards, and it was difficult for the medical staff on site. It was discovered in time that if B had tampered with and replaced the tube after the rescue was over, no one would have been found out, of course that is not the case now, the three interfaces are completely different now, and there is no possibility of wrong connections.”

After this professional output, Lin Dong already has a complete set of criminal behavior logic in his mind.It seems that Tan Xiaoguang was right to suspect that Mai Changsui had the opportunity to do something.The motive for committing the crime is unknown for the time being, but fortunately, we know where to arrest people and bring them back for trial.Life is not in vain, and fatigue is not in vain. If you can help Tan Xiaoguang reverse the case, it will be easier for Zhuang Yu to talk, and he should not be like before, always playing bureaucratic with him.Ming Shuo once said that he is a loan shark, one of the great pleasures in life is to let others owe favors, and when it is time to use it, he will withdraw the principal plus interest all at once.

The heavy pressure on his shoulders was lifted again, and Lin Dong relaxed, and he was in the mood to joke: "So it is said on the Internet that the situation of being pulled out of the oxygen tube by the child will not happen?"

"Well..." Qi Ming thought about it for two seconds, "It's fine to pull it out of your mouth."

"..."

Seeing his serious consideration, Lin Dong diverted his thinking a little bit—so solemn, could it be that he was thinking about the picture of pulling Luo Jianan's oxygen tube?
