Anseong looked at the construction site thoughtfully.

"Team An, what now?" Li Yang kicked the stone under his feet fiercely, touched his pocket and was about to take out a cigarette, but the pocket was empty, and he forgot to bring it when he went out.

"Where do the teeth of the dead go?" Luo Li muttered suspiciously.

They searched the scene of the dumping but did not find it, there were no fingerprints on the sacks, and they did not find anything left by the murderer.

"If you are asked to paint a portrait of the murderer, you will sketch it." Anseong made a suggestion.

"I'm here, the deceased was dismembered, it must have taken a lot of strength, this person has been engaged in manual labor for a long time, no traces of sexuality, invasion, rape, murder or love murder, the murderer knew that the deceased was a student of the second middle school in the city, and he knew everything about her skipping class, it was possible that an acquaintance committed the crime, but that little girl didn't seem to have so much strength, strange." Li Yang felt contradictory halfway through his words.

"Let's go back and take a closer look." Luo Li said.

Back at the police station, Anseong checked the body and the sack containing the body again.

"What is this?"

Luo Li looked at An Cheng and asked as she picked up a white silk thread with tweezers.

"Left by the murderer." Anjo said with certainty.

Later, after laboratory testing, it was learned that the white thread was a white thread knitted glove, which was commonly used by workers on the construction site, and the case had made great progress.

"The murderer is a male, grade over 40 years old, height over 170, weight 65 kilograms, foreigner, poor, low-key and honest, self-disciplined in life, wearing green liberation shoes, black pants, blue overalls, is a nearby worker, and the tenants near Xiaoyang Chacha City No. 2 Middle School meet the above conditions." An Cheng said with a deep sink.

"Security team, the test report has come out, there are traces of dried saliva on the deceased's face, and it has been identified by DNA that it is not the deceased, it may have been left by the murderer."

"Xiaoyang, take a team of people to a nearby construction site with me." Anjo said.

"Xiaoli, go find Xia Weiliang's girl, she may be a witness to the murder."

The police set off quickly, there is a construction site behind the No. 2 Middle School in the city, it is said that it is the renovation of the old house, the workers here work in shifts, the new building has been built very high, the outside is covered with a green cover, the sound of banging and banging comes from time to time, and it does not stop work at night, often disturbing the people.

When the police arrived, the ambulance had already arrived first, and it was said that there had been an accident at the construction site and someone had fallen from it.

When the ambulance arrived at the hospital, the worker was already dead, and the DNA was verified to match the saliva DNA extracted from the deceased.

In the small single room she rented, she found gloves, liberation shoes with no laces, and a pair of serrated teeth, which were used on the construction site.

"Team An, that girl with a cool summer went to class, and I couldn't find her." Luo Li said.

"No need." Ancheng waved his hand, the case has been solved, and the police have closed the case.

Anjo found a notebook that looked like a diary in the murderer's room, Anjo flipped through it, lit a cigarette from his purse, and the smoke covered his complicated emotions.

"The dead man's teeth?" Luo Li asked.

"Leave it alone, let's deal with the follow-up." Anjo did not answer.

Luo Li frowned, a little unhappy, but still didn't say anything more and closed the door.

An Cheng took a puff of cigarette and didn't tell her that the teeth should be in the hands of that little girl who was cool in Xia, but it was close to the college entrance examination, and he didn't want to add a psychological burden to the little girl.

The following is an excerpt from the diary:
