Forensics

After brief communication on the case, Bureau Ding said that there was a meeting, opened the door of the meeting room and walked to the left.

Gu Yanchen turned to the right and wanted to go back to the office. As soon as he came out, he saw Shen Junci standing not far from the meeting room.

Seeing Gu Yanchen, Shen Junci was taken aback for a moment, and then he explained slightly apologetically: "I didn't mean to listen to you here on purpose."

Gu Yanchen said: "It's nothing, and I didn't discuss any confidential issues."

Shen Junci looked at Gu Yanchen, and he heard something from the conversation just now: "Captain Gu, what you said just now makes sense, and I don't want girls to lose the right to dive with the person they like because of this case. .”

Love is sweet. If you can't go up the mountain to watch the sunrise hand in hand with your beloved, and dare not go into the water to see the beautiful scenery together, that is the loss of life.

Then Shen Junci said again: "I came to look for you just now because I wanted to tell you something. I watched the video again and found some details. I suspect that Liao Yinghan might have locked something in Xiao Zhong at that time. Ke's mouth, making her unable to breathe freely."

Gu Yanchen also remembered that although the image was blurry, Liao Yinghan made a movement, stretched out his hand and pulled Zhong Xiaoke, and then seemed to cover the woman's mouth and nose with something.

He suddenly remembered the confession of the lifeguard at the beach: "The people who rescued them also said that they saw something floating on the surface of the sea."

Maybe that's what covered Zhong Xiaoke's mouth.

Shen Jun resigned: "I'm going to go to the corpse storage room now for a second corpse check."

Gu Yanchen looked at the time: "Let's go together."

They walked to the basement of the forensic building together. Shen Junci filled out the formalities, got the key, and opened the cabinet where Zhong Xiaoke's body was stored.

The freezer was opened, and the woman's body lay peacefully inside, and a gust of cold air followed.

The frozen body was even paler than when it was first autopsyed.

After the white mist of the air-conditioning cleared, Shen Junci took a closer look at the face of the female corpse: "Sure enough, there are potential damage marks."

Gu Yanchen also noticed that there was a light brown mark around the mouth of the corpse, as if something had been pressed against her mouth.

Gu Yanchen asked: "Why can't I see this mark on the previous body?" He clearly remembered that there was no such mark on the previous body.

Shen Junci explained: "After the corpse is stored at -2°C for 24 hours before inspection, some inconspicuous marks on the surface of the corpse will become obvious. Especially for minor injuries after falling into the water, the effect is the best. So there are It is time for the forensic doctor to conduct a second examination of the body."

This scar was obviously not caused by the respirator. Shen Junci checked and measured it carefully, and then sent a message to Qi Yi'an, asking him to come back to take pictures and collect evidence, and add this point to the forensic report.

Gu Yanchen observed for a while: "This shape reminds me of the mask of an oxygen inhaler."

Shen Junci nodded: "Similar things are also used when measuring lung capacity."

Gu Yanchen suddenly remembered something. He took out his mobile phone and searched Zhong Xiaoke's Weibo VLOG. When introducing diving equipment, there was such a thing in Liao Yinghan's luggage...

It was a small plastic mask, placed in a plastic bag, with no external chain tubes, which could fit the curves of the face tightly, and once it was fastened, it was impossible to breathe.

Probably because she was alerted when she approached Zhao Yushan underwater, and she was afraid that the police would find out. This time, Liao Yinghan gave up on tampering with the oxygen bottle, but directly took off Zhong Xiaoke's respirator, and then pressed a mask on her face.

It wasn't that Zhong Xiaoke couldn't exhale the air in her lungs spontaneously at that time, but her mouth and nose were firmly blocked and she couldn't exhale.

Compared with Zhong Xiaoke, Liao Yinghan is both a man and a fitness trainer, and the strength of the two is very different. Liao Yinghan hugged her and quickly went up.

The warm embrace of her lover in the past became a life-threatening shackle under the deep sea. Such a move caused her lungs to burst and she died.

The rapid decompression also caused Liao Yinghan's nosebleed later.

The whole case finally straightened out.

Two people came out, sat in the car, and the car started.

It was the dusk of another day, during rush hour, and the road was a bit congested. When driving on the road, all the street lights on the side of the road suddenly lit up, like a galaxy falling to the ground.

Penang under the lights is beautiful.

Shen Junci watched the flow of people on the road for a while, then turned his head and asked softly: "Can that clue help you?"

"Of course, this is the direct evidence that Zhong Xiaoke may have died of homicide." Gu Yanchen paused and said, "I will make good use of this information."

Shen Junci lowered his head: "It's just a pity that this evidence is still side evidence. The mask couldn't be found, and the picture didn't capture a clear moment when her mouth was covered. We can't even prove when it happened of."

If the other party hires a better lawyer, or engages in sophistry, they still cannot use this evidence to convict.

After a moment of silence, Shen Junci asked again: "Captain Gu, are you sure about tomorrow's interrogation?"

Gu Yanchen: "I will do my homework to prepare in the evening."

The evidence was submitted overnight, and the arrest warrant from the procuratorate will come down tomorrow. At this point, it seems that the only way to go is to interrogate Liao Yinghan and make Liao Yinghan plead guilty.

Shen Junci hesitated for a while, seeing that the car was approaching the neighborhood, he asked Gu Yanchen: "Captain Gu, what do you want to eat tonight?"

Gu Yanchen said: "I guess I'll be a little busy, and I may not have time to do it."

Shen Jun resigned: "Then I'll order a takeaway."

After Shen Junci took a shower, the takeaway would arrive, and he brought it over.

Gu Yanchen had already occupied the table in the restaurant, and there was a table full of printed materials. He was about to clean up, but Shen Junci took the initiative and said, "Let's have dinner on the coffee table today."

The takeaway orders were roast beef and pigeon soup. After a meal, Shen Junci packed up the takeaway box and took the initiative to go for a walk with the dog.

After finishing all this work, he had no intention of leaving, but turned back and asked, "Captain Gu, what can I do for you?"

Gu Yanchen was also not surprised: "There are some materials that need to be sorted out."

Bai Meng has retrieved all the information about Liao Yinghan.It's just that these materials have not had time to filter and sort them out.

"For example, these are all the posts, forums, and Weibo records of Liao Yinghan in the past. We need to filter out useless information, and then draw out the information circle that can be used to sort out his psychological trajectory. Another example is these. His bank consumption records for many years." Gu Yanchen concluded, "These information can help us restore the truth."

Shen Junci took the pen and documents and sat on the sofa, watching them for Gu Yanchen.

Gu Yanchen was sorting out some records related to this case.

Shen Junci read it for about an hour, then handed over the screened information to Gu Yanchen.

Gu Yanchen looked through it: "Well done."

Shen Junci took the initiative to pick up another stack of WeChat records, and he asked Gu Yanchen: "Captain Gu, I've always wanted to ask you, did you study interrogation at the police academy?"

As a forensic doctor, he has always been curious about interrogation.

Asking a person to confess to a crime sometimes seems like an impossible task, but in front of those criminal interrogation experts, the prisoner will obediently tell the truth.

Gu Yanchen's criminal interrogation skills are very good, Shen Junci has seen some of his interrogation process, and feels that he is one of the best in this city bureau.

Gu Yanchen happened to be tired from reading, so he poked his head out from a pile of materials and gave him a simple explanation: "The learning in the police academy is very shallow, and most of it can only be learned through practice."

The so-called interrogation is actually a psychological game.It is to crush the suspect's psychology within 24 hours.As long as the prisoner's psychological defense is breached, he will confess his crime.

When talking about this topic, Gu Yanchen couldn't help but say a few more words.

"In the past, the Bureau of Forestry attached great importance to criminal trials." Then he felt a little regretful, "But it didn't work in the few years since I came to Bureau Wang. Bureau Wang often said that instead of chatting with criminals, it is better to search and monitor."

Since the leadership started not to pay attention to it, it is conceivable what to do next.

Gu Yanchen turned the pen in his hand and explained in detail: "Now surveillance and mobile phone records have replaced a lot of questioning. For example, in the past, if you wanted to know that a person abused a cat, you might have to run all over the streets and ask your relatives and friends. The speech technique made him admit what he had done. Now, you only need to see if he has searched or sent some videos, whether he has joined cat abuse groups, and then check the surveillance near his home. Put these The evidence is placed in front of him, and the confession will be obtained quickly. These conveniences have accelerated the pace of interrogation and detection, and have also made the basic skills of interrogation useless."

Shen Junci sighed: "But in our current situation, we can only place our greatest hope on the criminal trial."

"Yes." Gu Yanchen nodded.

Now, if they don't have a confession stating the crime and the motive of the crime, and meet a difficult lawyer, it is basically impossible to convict Liao Yinghan in court.

Criminal trial is a bloodless psychological battle, a bit like conducting an autopsy in a forensic room, not fighting on the front line, but the result is very important.

"When surveillance was underdeveloped in the past, those old policemen had magical speech skills. Unfortunately, many of their methods have been lost. The only thing that can be summed up is some foreign interrogation methods, such as Reed's nine steps."

Gu Yanchen felt a little regretful, and he continued: "I still remember when I first came to the criminal police, the forestry bureau once interrogated a kidnapper with a strict mouth, and the kidnapper refused to tell us where the little girl was tied up. The Forest Bureau has been keeping him up for two whole days, almost without sleep..."

Shen Junci hummed: "That was many years ago, right?"

He found that Gu Yanchen always remembered clearly many things Lin Xianglan had done and said.

Gu Yanchen said: "I remember this because it happened to be the college entrance examination at that time, and Bureau Lin's son was in that class. He fell ill, and Bureau Lin didn't have time to go back to take care of him. Later, he asked me to buy some medicine and send it there. "

Shen Junci lowered his head, he suddenly remembered that this incident seemed to happen on the last day of his college entrance examination.Only now did he know that Lin Xianglan was interrogating the kidnapper at that time.

He had the impression of delivering the medicine to him, but he had no idea at the time that it was Gu Yanchen who came.

In this way, it seems that they are going to push forward their first meeting by a few years.

It's just that at that time, he was standing inside the door, and Gu Yanchen was standing outside the door. They only talked a few words, but they didn't meet each other.
