National Forensic Doctor

The alibi witness was compromised and the alibi evidence became invalid, and Bai Yuequn himself could no longer hold on.

Just like the criminals Jiang Yuan encountered before, most of the sophisticated criminals are sophisticated and self-interested.

They can indeed survive interrogation if they can get away with it.

However, when judgment became inevitable, their attitudes were completely different.

"If I say it, does that count as surrendering?" Bai Yuequn looked at Lei Xin opposite him with a depressed expression.

"Whether I surrender or not is not up to me. It is up to the procuratorate and the court to decide. But if I tell the truth, I can put in a few good words for you. If you confess, you will be lenient."

Lei Xin tapped his yellow fingers on the table and couldn't help but feel like smoking.

Bai Yuequn stared at Lei Xin's yellow teeth and yellow hands for a long time. Before, a sophisticated person like him would not even look at a middle-aged smoker like Lei Xin. But now he could only sigh and said: "I believe you. I said."

He was tired, exhausted, sleepy, restless, and annoyed.

In order to complete the murder plan, he first dragged his boyfriend and tortured him until he fell asleep, and then dragged him to the cinema to watch a movie on the grounds of romance.

Bai Yuequn is very familiar with his new boyfriend. He is young, impulsive, has strong hormones, and is also lethargic. He plays more vigorously and falls asleep almost immediately after the excitement is over, which is enviable.

Bai Yuequn couldn't help it. In his dreams, he would always think of Yuan Yutang's deep affection and false love for him, and his desire to kill him lasted from the beginning of the year to the end of the year.

He loves him, he hates him.

Screening Hall No. 2 is also the hottest and most poorly ventilated screening room in the cinema. However, the chairs in the theater are very comfortable. If you go to watch a movie after a full meal, you will easily fall asleep.

Looking for another dull and long literary film, to be honest, when many viewers saw the title, they couldn't run away and had to fall asleep on the spot, exactly like Xu Yi.

However, Bai Yuequn couldn't sleep. He had to go to Yuan Yutang's apartment immediately. In order to avoid being discovered and save effort, Bai Yuequn went there on a shared bicycle (fortunately he was not stopped by the police, Goutou).

Unlocking the door and walking lightly upstairs, Bai Yuequn spent all his strength in order to kill people and vent his hatred.

He worked so hard, just like he did when we were together.

But he couldn't relax yet, he had to concentrate, do a good job of inspection, and clean his one-piece waterproof suit. In addition to fencing, Bai Yuequn also had a hobby of diving, so when he thought of killing people, he immediately thought of this. A full body suit similar to a diving suit.

As long as the head is wrapped and the clothes are not damaged, the blood stains on the body can be easily washed away with water, and the remaining amount will be very small, and the hair from your own leather shoes will not be left at the scene.

It's just that I have to change my clothes one more time and wear them outside, which is a little troublesome.

After finishing these things, Bai Yuequn had to ride his bicycle back to the cinema, enter through the staff passage with the assigned key, and then sit next to her boyfriend.

When the movie ended, I rushed into the hotel as soon as possible, took off all my clothes, and soaked them in laundry detergent.

To be honest, at the last step, Bai Yuequn almost couldn't hold on anymore, but the strange murder scene made him persevere, and he even felt a different kind of excitement.

"Where are the bloody clothes and the murder weapon?"

The most important thing is to see the evidence, Lei Xin asked.

Bai Yuequn said weakly: "It's still in the hotel, on the ceiling of the hotel's laundry room."

The hotel they stayed in that day provided self-service laundry services. There was a dedicated self-service laundry room. It didn't cost much, but few people used it during the week. During holidays, people on vacation would use it more.

However, it is not difficult to temporarily hide something in such a place, and it is also difficult for the police to find it.

What is really difficult for criminal suspects to eliminate traces of crime is the pursuit of permanence and perfection.

It is very difficult to eliminate anything permanently and perfectly. The corpse is like this, the murder weapon is like this, and the bloody clothes are like this.

In terms of the theory of material exchange, if your requirements are so high, more material will be exchanged, and the flaws will naturally be bigger, which makes it harder to hide.

Of course, the difficulty here is probabilistic, and when faced with the threat of the death penalty, few people are actually willing to take a chance on a 5% or 10% probability.

Bai Yuequn also wanted to deal with the bloody clothes and murder weapon later. So hiding it casually in the hotel saves a lot of crime costs.

If the police want to find these things, they will have to spend a lot of manpower and resources.

Bai Yuequn only spent 20 minutes.

He also took the opportunity to soak the clothes and murder weapon with laundry detergent in an attempt to destroy the biological evidence inside. It's useful and somewhat useful, but not much.

Lei Xin asked several key points clearly and basically locked Bai Yuequn.

The so-called alibi, or the "cleverness" of wearing big shoes on small feet, all become insignificant at this time.

Bai Yuequn's face gradually filled with tears as he told his story with Yuan Yutang.

The story of a rich boy and a middle-class boy is just that, it has always been that way, and it is still the same if it is changed to a male version.

After asking and signing several main criminal facts, Lei Xin remembered what Jiang Yuan asked him to ask before coming in, so he took out his notebook, looked at it, and asked again:

"Why did you choose this time to kill?"

This was a matter of criminal motive. According to Lei Xin's thinking, there was a high probability that there was some opportunity to pull the trigger.

Unexpectedly, Bai Yuequn smiled miserably and said, "Someone sent me a photo. After I saw it, I couldn't stand it."

The trigger was indeed pulled, and the reason surprised Lei Xin.

Lei Xin immediately asked: "What photo?"

"There are photos of Yuan Yutang celebrating people's birthdays, and there are also photos of people being tied up at night." Bai Yuequn said tiredly: "I once wanted him to celebrate my birthday, but he told me that these are Western dregs and not worth promoting. , is the IQ tax, blah blah..."

Lei Xin felt his scalp numb when he heard this: "Is that just for this?"

"Roughly the same."

"Where are the photos?"

"Burned."

"Burned? Why burned?"

"The other party requested it." Bai Yuequn said calmly: "I wrote a WeChat account with the letter, asking me to add him. After adding him, the other party asked me how I felt. I told him, and the other party said that he could provide me with Yuan Yutang. The latest news, but they asked me to start a video chat on the spot and burn the photos and notes. I burned them."

Lei Xin looked at Bai Yuequn's expression and felt moved. He expressed regret and said, "It's a pity for you, otherwise it could be considered a meritorious service. Or, if you can identify someone behind the scenes and you were incited to kill, your sentence can be reduced." of."

Bai Yuequn's expression suddenly changed. He had done so many things and was angry and angry. He even felt that he was not wrong and should not be punished.

After Bai Yuequn blew his nose vigorously, he opened his eyes and asked, "What now? Can the sentence be reduced?"

"You have to have evidence."

"I have WeChat evidence and I added his."

“A conversation between two people on WeChat is useless if you don’t know who is on the other side.”

"I took photos. Photos of photos." Bai Yuequn sat up straight and said, "Before I contacted him, I took them with a camera. The camera cannot be accessed online. Even hackers can see the photos in it. No. You can only view it if I enter the password."

Lei Xin:......

He decisively asked where the camera was and asked someone to pick it up.

Then, Lei Xin became more friendly and said: "You too, if someone asks you to kill, you will kill. If you are asked to burn evidence, you will burn evidence without thinking about the other party's purpose and origin, so you are not afraid of being betrayed by the other party. Are you going to be threatened by others in the future?"

"Don't be afraid, because they are more afraid." Bai Yuequn sat calmly.

Lei Xin was stunned and asked: "Do you know who it is?"

"It's just the eldest son of the Yuan family, or the second eldest son of the Yuan family, who else." Bai Yuequn's eyes were red, but at this moment he was playing with his fingernails with peace of mind, as if he had seen through everything.
