Wu Cuo knew very well that he had to come up with evidence to deal with such stubborn suspects, but they only had reasoning and no evidence now, which was really annoying.

Wu Cuo called Minghui and Xiaobai out of the room and said to the two: "Look for cigarette butts! Find the cigarette butt with Tian Xiaofang's saliva and Dong Yue's skin tissue, and you can solve the case!"

Minghui analyzed: "The cigarette butt was not found on the rooftop. It either fell down or was destroyed by Tian Xiaofang. The possibility of finding it...is unlikely."

"Then we have to find it. Cigarette butts are the core evidence of this case. As long as we have a little chance of finding it, we have to try it!"

The three of them set off immediately and returned to the Baopai Factory crime-invasion building. The cement road in front of the building was very clean, not to mention cigarette butts, it seemed that there was no dust at all and there was no dirty soles when walking.

Several people can only rely on the green belt between the cement road and the building.

The green belt is very wide and the area is half a football field. The factory is willing to build green space, probably because it wants to look environmentally friendly.

So, the next day, workers would always see three policemen in casual clothes looking for something in the grass with their butts sticking out.

During lunch in the afternoon, the three of them saw Wang Jianxin huddled in the abortion. Wang Jianxin's eyes dodged and his expression was not very natural.

On the second day of the search, the three of them received news from Yan Ruyu: There was a major breakthrough in the case!

It turned out that when the three of them returned to Baopai Factory to search for cigarette butts, Yan Ruyu left Dong Yue in the city hall.

He looked at the wound on Dong Yue's hand carefully.

Dong Yue shrank his right hand unhappily, "What? Police officer, are you burning the hospital here?"

"That's not. Since you are upright and not afraid of your shadow, don't mind our small examination of your wound, right?"

“What kind of check?”

"You will know then. Don't worry, we won't hurt you." Yan Ruyu didn't say in detail, but led Dong Yue to Xu Xinger's office.

When he arrived at the office, Yan Ruyu signaled Dong Yue to show the wound to Xu Xinger.

Dong Yue noticed the sign "Forensic Chief Office" outside the door early in the morning, and covered her right hand tightly and said, "What are you looking for a forensic doctor? I don't know how many dead people he has touched, don't come over! I don't want him to touch me!"

Xu Xinger had long been accustomed to professional prejudice. He shrugged and said, "Miss, forensic doctors not only dissect dead people, but also conduct disability assessments for living people. Besides, work is not limited to high or low..."

Yan Ruyu sighed, really not understanding where Xu Xinger got his good temper.

Advocating people to be kind is a matter of schools, prisons, and religious organizations. The police's task is to send the guys who have problems to prison.

"Ahem... Dong Yue, inspection is a must. You can choose to do it with Section Chief Xu to ensure that the techniques are sophisticated and you will not suffer. Of course, we serve the people and will definitely meet the people's requirements as much as possible.

If you don’t like Chief Xu, it’s OK. Let’s go to the hospital to do it. Chief Xu is only responsible for examining the things that are taken from your wound. If you think it’s interesting to delay time, we will accompany you."

Dong Yue still covered her right hand tightly, but she took two small steps back at a loss.

She knew that this time she had encountered someone harder than herself.

"Okay," Dong Yue compromised and finally stretched out her right hand, "I warn you that you dare to do whatever you want to do with my wounds. I will definitely complain to you, so that you can't afford to take care of it!"

Yan Ruyu nodded repeatedly, "No problem. Last time I left the reporting number to your old lover Wang Jianxin. Unfortunately, he didn't call him. Do I need it or not?"

This statement reminded Dong Yue.

"Oh, by the way, after talking to you last time, I thought about the situation on the night of the incident carefully. The more I thought about it, the more I felt that the murderer was Wang Jianxin."

Yan Ruyu raised her eyebrows, but she didn't expect that Dong Yue would frame Wang Jianxin so soon and leave him alone.

"Oh?" Yan Ruyu shook her head, "It's a pity that your description of the suspect last time was inconsistent. We think it's probably because you were too afraid at that time that led to your memory deviation."

"Yes, yes, I was really scared at that time." Dong Yue would take advantage of the situation and go down.

"So, after expert evaluation, we believe that your testimony is not sufficient to be accepted."

The expert, of course, refers to Yan Ruyu himself. He did not blush at all when he said this, and it was very natural.

"What?!" Dong Yue was shocked.

"Let's do a wound examination first, just as you can calm down."

In the next few minutes, Dong Yue was in a dull state throughout the whole process, and her typical behavior after the trick was exposed.

The wound examination was performed almost entirely under a magnifying glass.

Yan Ruyufei said that there were five or six small black dots as big as needles on the edge of the black and red burning area on the wound, which would make Xu Xing Er difficult.

The two of them wiped the wound with a cotton ball dipped in saline for a long time, wiped off a layer of dead skin, and several small black dots finally revealed their true colors.

It's a few hairs!

How can human hands grow hair?

Of course, people don't have hair on their hands.

The hair is an external object, and it is burned and left in the wound while burning.

Could it be Tian Xiaofang's hair left when the two of them were entangled?

Xu Xinger carefully took out three pieces of hair that were only 3,4 mm long.

"That's great! Please compare with the deceased Tian Xiaofang!" Yan Ruyu said.

Judging from Dong Yue's expression, the hair is very strong.

As an important suspect in this case, Dong Yue was urgently arrested, and Wu Cuo, Xiaobai and Minghui also rushed back.

The next day, the comparison result came out. The hair entrained in Dong Yue's wound was indeed Tian Xiaofang's.

In the face of ironclad evidence, her psychological defense completely collapsed, and she had to confess her crimes.

"I was on the roof that day. I was waiting for Wang Jianxin, but Tian Xiaofang came. She was smoking while calling people, and she was talking about the factory promotion of the workshop director.

The work of the workshop director was related to me, so I hid behind the elevator equipment box and eavesdropped. Only then did I realize that the location that originally belonged to me was occupied by someone recommended by Tian Xiaofang.

In addition, Wang Jianxin, the turtle shrunk, has not come yet, so I was very angry and wanted to mess with Wang Jianxin. Since the promotion has failed, he will divorce him no matter what, and then marry me.

But it’s not that easy. I can’t sue Wang Jianxin with the leader. I will have to stay in the factory myself in the future. At most, let his wife know about us, but Wang Jianxin is not afraid of his wife at all, and his wife doesn’t care about him at all. In fact, I can no longer put more pressure on Wang Jianxin.

However, when I saw Tian Xiaofang standing on the edge of the rooftop smoking, a thought flashed through my mind.

What if it is a charge of murder? If my testimony can determine whether Wang Jianxin will be charged with murder, if I can control his life, will he succumb to me?

I didn't think too much at that time. It was just this idea. When I realized it, Tian Xiaofang had been pushed downstairs.

I habitually left the stair corridor, avoided the surveillance camera in the elevator, and called the police.

But……"

Dong Yue looked at the wound on her hand, "Maybe she died too unfairly and was too unwilling to accept it. Unexpectedly, she accidentally left evidence on me before she died.

It's good that you caught me. I have been dreaming of Tian Xiaofang these two days. She kept crying with me. Tears, blood, and brain matter flowing out of her eyes, and her limbs were also deformed. She asked me why I killed her, and she even rushed to strangle me to death.

I... can't stand it anymore."

The case was solved, but the group of people in a serious case were in a very heavy mood.

A life disappears in a thought. Is there any boundary between good and evil in human nature?

Perhaps, every detective will spend his whole life exploring this issue.
