Detective: I can see the criminal record

Forensic doctor Lin cleaned the skull very gently, and it took some time to extract all the skull and some broken bone fragments.

She also instructed her assistant to extract some soil and insect samples.

"Why does this skull look weird?" Tang Hua wanted to see but didn't dare to get too close. "Under normal circumstances, will the skeletonization produce so many bone fragments?"

Wu Qiushan took the bag of broken bones from the hands of Lin's assistant.

Forensic doctor Lin glanced at Tang Hua, "Of course not, the bones of the cervical vertebrae should have been crushed by a sharp weapon."

"It looks like some kind of mixer," Wu Qiushan raised his head after carefully studying the bone fragments, "The more common ones are cement mixers and meat grinders, and some large industrial equipment have such devices. The specific type needs to be confirmed."

The outdoor environment is not suitable for continuing to analyze the source of the skull and other bones. Cen Lian and Wu Qiushan followed Lin to the funeral home, and the others went back to the team to investigate the children reported missing in recent years.

After the last abduction case, the scope of this investigation has become much smaller.

On the way, Cen Lian asked Lin, "Sister Lin, how old do you think this skull belongs to?"

Lin Xiangqi was resting with her eyes closed, and only opened her eyes when she heard Cen Lian's question.

"According to my rough judgment, it should be 6-9 years old," she sighed slightly, "It's not easy to determine the source of the body at such a young age."

"The rest of the body should have been lost," Wu Qiushan rarely said such a sure thing at the beginning of the investigation. "I can be sure that the knife marks left on the skull are some kind of large mixing equipment. If it fell in accidentally, it would be good luck to leave this relatively intact skull. If it was intentional, the rest of the body should have been completely crushed at the time."

With the clues and evidence found now, it cannot be ruled out that this was an accident for the time being.

Although everyone in the support squadron has treated this case as a murder case, there is no way to rule out the possibility of concealment after a production safety accident.

But no matter which one it is, this case needs to be investigated further.

The funeral home in Taishan District was still a bit lively in the afternoon.

When Cen Lian and his team drove in, they saw a family in mourning holding an urn, and a man and a woman followed the staff to send the body of an old man who had just passed away to the freezer in silence, and then went through the cremation procedures.

The people coming and going were of all kinds, each with their own sorrow, which made Cen Lian and Wu Qiushan seem a little out of place.

Although Lin, the forensic doctor, was not wearing a white coat, he seemed to be integrated into the funeral home as soon as he entered the funeral home.

"The municipal bureau recently mentioned that the entire support squadron should be transferred together," Wu Qiushan told Cen Lian about the work transfer in the bureau after the forensic assistant went to help prepare things and left, "the branch office still refused to give in."

He did not avoid Lin, because Lin was always tight-lipped and did not like to gossip with others.

But this time she was rarely interested.

"If I'm transferred to the Municipal Bureau, I won't have to come to the funeral home every time for autopsies," Forensic Doctor Lin complained. "The space in the funeral home here is too tight, and the sound insulation is not good. When performing autopsies, I often have to listen to funeral music and passionate commentary five or six times a day. It's so annoying."

It was the first time that Cen Lian heard Forensic Doctor Lin complain about her work environment.

He thought that after working as a forensic doctor for a long time, Forensic Doctor Lin had become desensitized to such sounds.

After complaining casually, Forensic Doctor Lin carefully poured the skull and other bone fragments from the evidence bag onto the autopsy table.

"General dismemberment rarely leaves so many fragmented bone fragments," she said after carefully putting them together for a while, "It is impossible to completely piece together a whole piece of bone from the cervical spine, and these fragments are mixed with bones from other parts."

Cen Lian and Wu Qiushan went to see the skull together.

"How long was the time of death?" Cen Lian asked.

"I can only give you an approximate time of death, about two years ago. The specific time will be determined after the results of insect culture come out. I will give you a detailed autopsy report." Forensic Doctor Lin could not judge how long a skull that was almost completely skeletonized had been dead by naked eyes.

This time range can help them rule out not many missing children.

"It is more likely that the deceased is male, but because the deceased is too young, this conclusion may not be accurate," Forensic Doctor Lin also felt a little difficult. "After puberty, the skull development of boys and girls will produce significant characteristics. At the age of the deceased, it is hard to say."

A child's skull that only knows the approximate age, height, weight and other specific data cannot be estimated, and it is even difficult to determine the gender is indeed a problem.

"Although I can do skull restoration, my level is very average. If you really can't determine the source of the body in the end, I can try." Forensic Doctor Lin finally said this.

The technology of skull restoration seems to appear frequently in major criminal investigation TV dramas and novels, but it is still quite difficult to operate in practice. After all, there are very few people who have both a basic knowledge of fine arts and even studied sculpture, are proficient in operating computers for 3D modeling, and have a relatively in-depth study of anatomy and anthropology.

However, there is a university in Kang'an City that has such a talent, but this professor is not a forensic doctor. The last time he did craniofacial reconstruction was for a Qin Dynasty prince who had been dead for more than 2,000 years.

"If it doesn't work, we can go to Lingxi University to ask for help," Cen Lian still thought of a way out, "They can do it for more than 2,000 years ago, and they can definitely do it for people who have been dead for more than two years."

The meteorite that Lingxi University lost before has been returned after the case was closed, and Cen Lian also helped them avoid a campus poisoning and murder case. This is probably a face.

Forensic Doctor Lin is really not good at this technology. When he heard that Cen Lian decided to go to Lingxi University to find someone for help, he felt a lot more relaxed.

"Craniofacial restoration takes a lot of time. If you don't have other clear clues, I suggest you go to the professor now. It's best to advance in multiple directions at the same time." As the nominal deputy squadron leader, Forensic Doctor Lin still has to give Cen Lian suggestions.

Cen Lian thought for a while and finally made a decision, "We will investigate from the direction of the mixer. I will go to Lingxi University to find someone to help with the skull restoration tomorrow."

The case of old bones has always been the most difficult to investigate. Cen Lian did not expect to find out who the murderer is immediately. Judging from the current situation, it is the best choice to investigate step by step.

Forensic doctor Lin still had to do some follow-up identification, so he didn't go back with them.

Cen Lian drove the car and asked Wu Qiushan what he thought about the case.

"If it wasn't an accident, it could only be revenge." Wu Qiushan thought about the broken bones, "I'm more inclined to believe it was a revenge killing."
