Things that solve crimes

The forensic assistant had a look of regret on his face. He was so young and his family knew how sad he was.

Qin Henian continued to examine the bones, "Scoliosis may be caused by irregular dance movements."

14 years old, may have learned dance, and with a missing person report, the source of the body can be easily determined.

As for why a missing person report is added, which parent would not call the police if their child is missing?

When working on a case, the biggest fear is unreality.

As long as there are clues, no matter how much manpower and material resources are used, there will be no sound from above.

Qin Henian handed over the clues, and the task force quickly launched an investigation.

14 years old, unless there are special circumstances, there is no doubt that he is definitely a student.

Listing the missing students in Nishiki City and surrounding areas, the task force quickly identified one person.

Yu Li.

A native of Chongqing City, a student of No. [-] Middle School in Chongqing City.

After DNA comparison, it was confirmed that victim No. 7 was Yu Li.

This also proves that the murderer's hunting scope is not limited to this city, which is a bit inconsistent with the murder rules.

Faced with the murderer's unreasonable behavior, the task force couldn't help but reflect.

How extensive was the killer's hunting range?

Logically speaking, since the murderer dumped the body locally, he should also be from the local area, but victim No. 7 was from the next city.

Could it be that the murderer lives next door?

Killing someone next door and then abandoning the body in Jincheng City is not impossible, but it is not very friendly to the task force, making it more difficult to solve the case.

For two days in a row, there were all kinds of quarrels in the city bureau conference room.

Yu Li's information has also been investigated. It cannot be said that it is irrelevant and useless.

Yu Li is a student. She lives a life between school and home every day. She also interacts with people of the same age, so she doesn't find anything unusual.

The task force was "quarreling" here, while Qin Henian was in the autopsy room studying bones.

The corpses had been soaked in water for a long time. Except for corpses No. 6 and 7, which were relatively fresh, most of the skin and flesh of the rest of the corpses had rotted away. The exposed white bones had different color and texture changes.

Even if corpse No. 6 is not completely decomposed, it will be difficult to determine the source of the corpse. The remaining corpses No. 1, 2, 3, 4, and 5 are also complicated in their own way.

There were five corpses on the autopsy table. Qin Henian looked at the five corpses one by one, and finally fixed his eyes on corpse No. 5.

Corpse No. 4, starting from this corpse, all the subsequent corpses were found to have traces of cutting machines.

But there were not only traces of a cutting machine on corpse No. 4, but also traces similar to an axe.

The ribs of this corpse were chopped off with something like an axe, and the leg bones were chopped off with a cutting machine.

Qin Henian began to study the ax marks on corpse No. 4.

There are many types of axes, such as fire axes that are not common on the market, axes that are used to chop wood, etc. If you can determine the type of axe, you can also get certain clues.

Facts have proved that Qin Henian underestimated the tool mark inspection, and a dabbler like him could not figure out the origin of the axe.

To determine the time of death, this clue was also crossed.

Generally, the time of death of a corpse is determined by looking at the degree of insect reproduction on the corpse. If a fresh corpse is still steaming, it can also be judged by measuring the liver temperature and rectal temperature.

In this case, the corpse had no liver and no anus. The flesh of the fresher corpse at the back had been picked off by the murderer. It hasn't been found yet, so don't expect to find the insects.

In the end, all that could be studied were the marks on the bones.

Human skeletons can provide a lot of information, and many traces of life can be found on them.
