Detective: Open your eyes, I am handcuffed in the interrogation room.

Chapter 464: Forensic Doctor Qin Lang
Files are files, they are dead. Only objective facts are recorded in them. But files will never record the entire case. Something will always be left behind.

The remaining details cannot be put into black and white. They are either speculations or lack of evidence. Regarding this aspect, Chen Yi wants to have a good chat with Sun Shuxiang.

They are all professional criminal investigators, they have a common language and there is no need to hide anything.

"Captain Chen, are you referring to this?... Yu Zhanlin deliberately got Yan Lina drunk so that he could use sex toys on her when she lost her ability to resist?" Sun Shuxiang spoke after thinking for a moment.

Chen Yi: "Yes."

Sun Shuxiang hesitated: "But Yan Lina was not drunk. We have watched the surveillance video many times. She was sober when she left the bar and entered the hotel, including before entering the room. She could walk on her own and did not drink any more alcohol after entering the room."

Chen Yi did not respond directly to this, but turned to look at Director Li and said with a smile: "Has Director Li ever been drunk?"

Director Li: "Of course, there are not many men who have never been drunk."

Chen Yi: "I was drunk before, but that was many years ago. Everyone's drunken state is different. Take my experience for example. When I was drinking, I was in high spirits. I kept drinking and drinking. Although I was dizzy, I was very sober. I could speak normally and had no urge to vomit. Walking was even easier."

"However, when I left the room and was blown away by the wind, the aftereffects immediately came on and I vomited all over the place."

"That time, I blacked out for more than an hour. I remember that my friend took me to the hospital for an IV drip. I was given glucose and benzene to protect my stomach. It was very painful."

Director Li has been to countless drinking parties and seen many drunk people, so he agrees with what Chen Yi said: "Yes, yes, there are such people. If you say he has a good alcohol tolerance, he will get drunk as soon as he goes out. If you say he has a bad alcohol tolerance, he will never stop drinking at the table."

Chen Yi: "What is Director Li like when he's drunk?"

Director Li laughed: "I fell asleep right away. The most embarrassing time was when I fell asleep right on the wine table. But I didn't vomit the wine. I never vomit. I just fall asleep when I have enough wine. It can be considered as self-protection of the body, right?"

Chen Yi also laughed: "Director Li is the best. His body knows his alcohol tolerance and responds accordingly. I am more miserable. I have never passed out at the table, but my body is actually overloaded."

After saying that, he looked at Sun Shuxiang again: "Where's Captain Sun? How drunk is he?"

It was originally a casual chat and a joke, but Sun Shuxiang couldn't laugh. After a moment of silence, he said, "It's possible that Yan Lina was drunk when she entered the room."

Chen Yi: “So?”

Sun Shuxiang: "So Yu Zhanlin may have deliberately made Yan Lina drunk to achieve his own goal, and then overexerted himself in the room, causing Yan Lina's death. In this case, it was not an accident, but negligence."

Negligence and accident are two completely different concepts. The latter only requires compensation, but the former requires legal liability.

The law stipulates that manslaughter by negligence will generally be sentenced to fixed-term imprisonment of not less than three years and not more than seven years. If the circumstances are relatively minor, the sentence is not more than three years in prison.

Although Yan Lina's death was mainly due to underlying diseases, she was unconscious when external forces intervened, which meets the criteria for manslaughter.

The logic is correct, but the problem is that it cannot be verified.

Yan Lina is already dead, but Yu Zhanlin said she was conscious, and no one can question that.

Yan Lina was awake under surveillance. The court only looks at the existing evidence and cannot rely on subjective speculation.

Seeing that Sun Shuxiang was hesitant to speak, Chen Yi spoke up: "I don't sympathize with Yan Lina, nor do I have a grudge against Yu Zhanlin, and I am not targeting Deputy Director Yu. Captain Sun, are you asking me why I doubt you? This is a presumption of guilt, right?"

Sun Shuxiang quickly said, "No, no, Captain Chen misunderstood. I definitely didn't mean that."

Chen Yi smiled and said, "Captain Sun, don't be nervous. This is just a private gathering tonight. Don't think I want to overturn the case. Just think of it as a discussion between... frontline criminal investigation police. Discussions must have examples, and the current case is an example."

This was closer to the point. Sun Shuxiang felt relieved and a smile appeared on his face.

I have to say that people with the same profession can more easily talk to each other. Narcotics police have a common language, economic investigation police have a common language, and criminal investigation police have a common language.

Although there is a big gap between the two parties' positions, at least they both come from criminal investigation backgrounds.

This is the closeness that comes from having the same profession.

"Xiao Sun, learn more from Captain Chen. Opportunities like this are very rare." Director Li said, "You've done a good job in the past year since you were transferred here, but you've been slow in handling some cases. Ultimately, it's because you lack the ability. You need experience. Take advantage of it. Maybe something Captain Chen said casually can help you solve cases more easily."

These words were really beautifully said. On the surface, they were meant to encourage Sun Shuxiang, but in fact, they were praising Chen Yi, and the praise was very well-crafted.

In a word, the crime-solving rate has been improved, which puts Chen Yi in an extremely high position, at the level of an industry leader.

Even Chen Yi felt a little embarrassed, but... he loved listening to it.

Who doesn’t like to hear good words?

Zhuge Cong and the others looked in awe. You have to learn this well. Flattery is not encouraged, but it is better to say good things than bad things, right? Who doesn't want to be a person with high emotional intelligence and be liked by everyone?

"Yes, Director Li."

Sun Shuxiang lowered his attitude, not just for show, but out of his genuine admiration for criminal police like Chen Yi.

To be able to reach the position of deputy captain, one must rely on a real crime-solving rate. I heard that some of them will even be included in the police academy's elective textbooks for all prospective police officers to study.

"What do you think of the signs of binding?" Chen Yi asked.

Sun Shuxiang: "The marks on the wrist?"

Chen Yi: "Isn't it just a trace?"

Asking questions even though you already know the answer is a habitual confirmation and is part of normal communication.

Sun Shuxiang recalled the condition of the body and the autopsy photos, and immediately understood what Chen Yi wanted to say: "Hands tied behind the back?"

Chen Yi: "What do you think?"

Sun Shuxiang frowned slightly, thinking and speaking: "If they tied their hands behind their backs, then Yu Zhanlin would be lying. However, the binding techniques and force points are different for each person. Both of them drank alcohol, so the marks may be different from normal."

Chen Yi: "What about delayed alarm?"

After discussing these two doubts, Sun Shuxiang's brows furrowed deeper and deeper. After this conversation, it seemed that there were many problems with Yu Zhanlin.

But...it cannot be verified.

After entering the hotel room, everything was blank. All we could do was to follow what Yu Zhanlin said. Unless his confession conflicted with the clues we had, it was the truth.

Sun Shuxiang presented facts that could not be verified, and Chen Yi did not refute them. This case was indeed affected by many subjective limitations.

Subjective, and difficult to verify in cases where the victim is dead.

It is precisely because clues are subjective that there are disputes.

"How good is Yu Zhanlin's lawyer skills?" Chen Yi talked about the trial.

Sun Shuxiang said: "It's of a very high standard. I heard that it cost a lot of money. Yu Zhanlin's family even sold a house to cash in. The full amount was paid."

Chen Yi nodded slightly, and the two words "Brother Hao" popped up in his mind.

Lawyers play a decisive role, even when the evidence is solid, let alone controversial cases.

It is certain that the scale of judgment will tilt towards whichever side has the more skilled lawyers.

Originally, Yu Zhanlin could have been convicted of manslaughter, with a sentence of one or two years, but the defendant's lawyer obviously did an excellent job and successfully defended his innocence.

Otherwise, why do you say it is expensive? There is a reason why it is expensive. Top lawyers even understand the law better than the courts.

At this time, Deputy Director Wu, who had been listening, spoke up: "Captain Chen, if you think there are doubts in this case, you can review and re-examine it. As police officers, we should investigate any doubts."

Chen Yi looked over and was about to speak when the other party added, "To be honest, this has absolutely nothing to do with personal grudges. In fact, Lao Yu and I don't have any hatred. We just have different personalities. It's normal. Captain Chen will definitely understand."

Hearing this, Chen Yi thought for a moment and looked at Director Li.

Director Li stated: "I will obey Captain Chen in everything."

Now is the suspicion stage and there is no need to go through the degree process. If substantial evidence is found to prove that the verdict is wrong, the victim's family needs to appeal to the court and retry and re-sentence the case after the ruling.

Even the final judgment can be appealed.

There is a difference between appeal and complaint. Although there is such a provision, the success rate is very rare. Ninety-nine percent of the cases have gone through criminal investigation and prosecutorial review, so it is almost impossible for loopholes to exist.

There is a small probability that the unexpected situation is that the query is wrong.

Because of the mistake in the investigation, Deputy Director Wu and Sun Shuxiang were both implicated, but their reactions seemed quite calm.

An even more unexpected situation is fraud.

Chen Yi picked up the cigarette box and handed out cigarettes, saying, "It's not necessary to re-investigate. I'll learn more about it. I'm not in a hurry to go back anyway. I'm sorry to bother you all."

A few people were polite and said they would not bother him at all.

Afterwards, Chen Yi asked Sun Shuxiang several questions that were not in the file.

For example, does Yu Zhanlin have a motive to kill someone intentionally, or even a slight possibility, to make the killing an accident?

This is the key direction of the investigation. Sun Shuxiang has already confirmed that the two are in a normal relationship and have a good relationship. No problems have been found either from visits or chat records.

For example, was there anything wrong with Yu Zhanlin's expression when he was facing interrogation?

This will not be recorded in the files.

Sun Shuxiang still gave a negative answer, and said conservatively: "I didn't find it. How about Captain Chen take a look at the interrogation video?"

"Okay, let's talk about it tomorrow."

Chen Yi continued to ask the next question: Was there any sudden change in the situation during the investigation?

Sun Shuxiang almost didn't react. Was this a subtle inquiry into outsider interference? He was just short of mentioning Deputy Director Yu's name.

"No, no, that's definitely not the case."

The meal lasted until after eleven o'clock in the evening. Since it was not a business investigation, Chen Yi declined Director Li's offer to arrange accommodation for them, and the few of them found a mid-range hotel nearby.

I guess it can't be reimbursed.

Chen Yi asked Xia Lan to record and issue the invoice normally. I took the initiative to work overtime, so why can't I be reimbursed? If I can't be reimbursed, I will go to the police security department to have a good talk with the director. No one can go home without a signature.

I have my own money, but I feel more comfortable spending public money.

"You guys can go for a walk tomorrow. Qin Fei and I will go to the Tieping Branch. We can contact you by phone anytime."

After giving the order, everyone went back to their rooms to rest.

A total of four rooms were booked, Xia Lan had one alone, and the other six people had two in each room.

Chen Yi and Qin Fei live together.

"Captain Chen, do you really suspect there is something wrong with this case?" Without outsiders around, Qin Fei went straight to the point.

Chen Yi: "Yes, based on my experience, the files are not correct and there should be omissions."

Qin Fei: "Where?"

Chen Yi: "If I knew, I wouldn't have this dinner tonight."

Qin Fei said, "Do you have a clear direction for going to Tieping Branch tomorrow?"

Chen Yi got on the bed and said, "Yes, the chief detective involved in the case investigation needs to be asked."

Qin Fei was puzzled: "Isn't it Captain Sun?"

Chen Yi turned around and said, "Can you think faster? Sun Shuxiang is in charge of the case investigation. What about the technical investigation? Sun Shuxiang cannot control the results of the technical investigation. He only knows the part he is responsible for."

Qin Fei scratched his head and said awkwardly, "Trace examination and forensic examination, right? My negligence."

Chen Yi: "In the future, you should think about problems comprehensively and not just focus on what is in front of you. Often, what you can see right away is what you least need."

Qin Fei: "Yes, Captain Chen."

Silent all night.

The next day, Chen Yi, who did not get up on time, slept until he woke up naturally. After they had breakfast together, Qin Fei drove Chen Yi to Tieping Branch.

The time to enter the police station is 9:40 in the morning.

The day's work has just begun.

What a coincidence, I met that auxiliary police officer again. It's really fate.

For this auxiliary police officer, he really didn't want to meet Chen Yi again. Although it was a good opportunity, he knew his own limitations and he had no chance to catch him. Instead, it might have a counterproductive effect.

He had already been scolded by the captain for what happened last night. It was the captain, not the team leader. After the captain scolded the team leader, he even said a few more words to his own brother Wang.

How miserable.

I was lucky enough not to be fired directly.

What a bad luck! I obviously didn't do anything.

"Team Chen!"

The young man stood at attention and saluted, but it was not very standard and a little funny.

Of course Chen Yi couldn't argue with a junior. It was not easy for a young person to find a job.

"Where is the forensic office?"

"The third room on the right on the second floor! Brother Qin seems to be here. Director Ma is in a meeting!"

"Ah."

Chen Yi nodded and went upstairs with Qin Fei.

The auxiliary police officer breathed a sigh of relief and said, “There should be no problem this time, my answer was perfect.”

There was no elevator, so Chen Yi and his companion took the stairs. Just as they reached the corner of the second floor, a young man passed by. After seeing Chen Yi, he stopped and stared at Chen Yi's face.

Two seconds later he seemed to recognize it and immediately cursed.

"Fuck!"

“Chen…Captain Chen? Holy shit… they look alike!”

The stuttering idol made Chen Yi's liver tremble, and he looked at the other party suspiciously: "Who are you?"

"Captain Chen! My name is Qin Lang! I'm the forensic doctor at the Tieping Branch, and I just got a full-time job last year!"

Qin Lang's voice was clear and he stood there like a soldier.

Qin Lang?

The Brother Qin that the auxiliary police officer mentioned just now should be him. He looked very surprised and probably hadn’t heard about last night’s news yet.

"I'm going to find your leader." Chen Yi said.

Qin Lang: "Captain Chen, I'm going to the meeting."

Chen Yi waved his hand: "Then go to the forensic room and wait."
