I don't know how long it took, Lin Shu took the lead in breaking the silent deadlock, "We have to give Li Wei an explanation." ”

Zhou Yinglin also quickly overcame the psychological barrier and devoted herself to work. She used a hemostat to open the deceased's nasal cavity and then pried open the closed teeth, revealing only a small amount of sediment and algae, which was completely different from drowning in a pond.

"There is not much sediment and algae in the nails, mouth and nose, combined with your findings, this is very likely to be murder, report the situation to the bureau leaders and apply for an autopsy." The chief forensic physician, Zhou Yinglin, made a conclusion.

With the opinion of agreeing to the autopsy, Zhou Yinglin skillfully cut open the chest and abdomen of the deceased.

"There is obvious bruising in the internal organs, pulmonary edema, and a crepiting sensation." Then Zhou Yinglin cut the deceased's trachea, "The trachea is congested and there are adherent bubbles on the tracheal wall, which is consistent with the characteristics of drowning death before death." ”

"It's true that it's drowning, but the fact that there is not much sediment in the fingertips, mouth and nose still makes me very concerned, let's cut open the stomach and look at the drowning." Lin Shu, who was still not at ease, proposed.

After making an incision in the stomach, Lin Shu used a clean scoop to load the drowning fluid in the stomach into a clean beaker, "The drowning fluid is clear, there is no algae, sediment, Li Wei was killed indoors and dumped in the pond." It could be a sink at an orphanage or a place with running water in a nearby village. ”

"Since it was drowning indoors, the murderer needs to press the deceased's head into the water, then the deceased should have a corresponding subcutaneous hemorrhage at the back of his head, shave his hair."

A good shaver is not necessarily a good forensic doctor, but a good forensic doctor must be a good shaver. Lin Shu was no exception, he was responsible for shaving the hair of the deceased, while Zhou Yinglin was responsible for suturing the chest and abdominal cavity.

After a while, the bare back of Li Wei's bare head in the prone position was revealed. As expected by the two of them, there was a subcutaneous hemorrhage on the left and right sides of the deceased's head, which should have been traces of palm and thumb compression.

"Combined with a small amount of bleeding from the mucosa of the mouth and nose and the binding wound of the upper arm, it should be possible to roughly restore the murderer's criminal process. While there is still some time before the briefing on the case, let's simulate it and give Team Xing as many clues as possible. Perhaps it was the loss of her young life that stung Zhou Yinglin, and she seemed to work harder than usual.

"Okay, I'll play the murderer, and you play the victim." Lin Shu didn't have any reason to refuse.

"Are you sure you're going to play the murderer and assault me?"

"It's really inappropriate, you play the murderer."

The two of them went to the open space on the side of the dissection room and began to rehearse.

"The murderer should have wrapped around Li Wei with one hand and covered his mouth and nose with the other to prevent calling, which is also consistent with the bleeding from the mouth and nose and the upper arm restraint injury." Zhou Yinglin hugged Lin Shu with one hand and covered her mouth and nose with the other. However, Lin Shu, who is more than 180CM, is still a little difficult for her, and Lin Shu can only squat down slightly to cooperate.

"Then take it to a relatively separate place with a pool." The two moved to the sink in the dissection room, "took off Li Wei's pants, pressed Li Wei's head and began to violate." ”

The policeman in charge of the video on the side looked at the indescribable positions and movements of the two, and his face gradually turned red.

"Maybe it was to cover up the sound, so the murderer turned on the faucet, but did not find that the drain was blocked, and finally killed Li Wei by mistake." Lin Shu made his own inferences based on the scene restoration.

"It is very likely that the murderer who later found out that Li Wei had died put his pants back on him and dumped his body in the pond."

At the case briefing an hour later, this scene was also staged, but the actors were replaced by Lin Shu and the blushing policeman, after all, the picture is not very elegant if Zhou Yinglin plays.

"That is, the killer controls the victim to something like a sink, then assaults it, and finally kills someone." Xing Xie said the facts that all the police officers who handled the case were unwilling to say or hear.

Lin Shu could see from Xing Xie's clenched fists that this man's heart was definitely not as calm as it appeared.

"What about DNA testing for residual semen?" The experienced Liu Jianshe put forward important clues for all sexual assault cases.

Xing Xie shook his head, "It's very difficult to compare, the day of the crime is an open day, Aunt Mei's old colleagues from the former hospital and health school, the students of the health school, and the children who went out of the orphanage will come a lot, counting the nurses and security guards of the orphanage itself, there are nearly 30 men here, and if you add the nearby villagers, there will be no less than 100 people." We can't just rely on DNA matching, we have to narrow down the number of suspects with precision. ”

The entire criminal investigation team was silent at this moment, although everyone wanted to give justice to that innocent and lovely child, but there were too few clues left for them.

"Maybe we can try to find the sink where the crime occurred, if the victim was really pressed against the sink, then his hands would definitely be holding on to the wall of the pool, and it is very likely that the victim's thumb fingerprints remain in the places where the outer wall is difficult to be washed." One of Lin Shu's proposals fell like a drop of water into a hot oil pot, and everyone immediately went into action, inspecting the entire orphanage and nearby villagers' homes for sinks or similar objects.

Under the full investigation of the criminal investigation team, it took less than two hours to find two fresh children's thumbprints on the outer wall of a sink in a toilet in the orphanage. If it can be matched with Li Wei, it can be determined that the orphanage is the first crime scene, then the number of suspects will be greatly reduced.

Not long after, Qi Xin ran into the office of the Criminal Investigation Brigade with a comparison report, "The fingerprint is Li Wei's." ”

The news undoubtedly lifted the entire office uplifted, as they all knew that they were getting closer and closer to the real culprit.

Snuffing out the cigarette in his hand, Xing Xie shouted: "Everyone is dispatched to Lao Tzu, according to the list, invite all the people who have been to the orphanage that day, and if you don't want to come, press me over." Xiaoxiao, you write an application to the bureau leader, requesting that the DNA of these people be extracted for comparison. ”

"Yes."

"Zhang Dong follow me, go to the Municipal People's Hospital, Lao Liu will take a few to the health school, and you will go to the orphanage."

Lin Shu took Zhou Yinglin and ran to Xing Xie who was about to get into the car, "Let's go too, we also want to contribute to Xiaowei again." ”

Looking at the firm eyes of the two people in front of him, Xing Xie nodded, "Keep up." ”

"Okay."

Xing Xie drove a seven-seater Buick police car to the Municipal People's Hospital, and the sound of sirens sounded throughout the morning streets.

"You two are waiting in the car, and we'll go up and arrest someone." Xing Xie's order didn't give the two of them a chance to refute, so he took Zhang Dong upstairs.

After a long time, there was a sudden commotion in the hospital building, and the two got out of the car and watched by the car.

Suddenly, two men ran out of the emergency building, the one in front of him was wearing a doctor's uniform and running hard towards the exit, and the one behind was Xing Xie, chasing and shouting not to run.

Seeing this scene, Zhou Yinglin ran up without saying a word, intending to stop the man.

Seeing this, the man also panicked, brandished the scalpel in his hand and rushed straight at Zhou Yinglin, shouting in his mouth: "If you don't want to die, get out." ”

I don't know where Zhou Yinglin got the courage, but she refuses to back down.

Lin Shu also hurriedly rushed over, but after all, he was still a step too slow.
