Jiang Feng locked this case later.

He directly took out the three volumes, that is, the homicide case investigation file, the current investigation file, and the physical evidence file.

Watch it alone.

The three interns on the side were all secretly paying attention to Jiang Feng, the imaginary enemy, and now seeing that Jiang Feng seemed to have locked onto the target, they were all a little unconvinced and unconvinced.

Can you find the entry point so quickly for this adult backlog of unsolved cases?

I don't believe it!!

A man who looks so handsome should be nothing but handsome!

It can't be so good anymore, or it won't give people a way to live!!!

Jiang Feng didn't know anything about what others thought.

He scrutinized the file.

To sum up this case, the main problem is actually obvious.

First of all, the identity of the deceased cannot be confirmed, and secondly, the terrain of the area where the occurrence occurred is complex, there is no surveillance, it is very close to the provincial road, the flow of people and vehicles is mixed, and the appearance of rare heavy snow leads to a very low probability of witnesses, and it is extremely conducive to the concealment of the murderer's traces.

After a heavy snowfall, the world was cleaned, and all traces of the murderer's crimes disappeared with the snow.

"There are many difficult points, but from the analysis of the murderer's situation, the identity of the murderer can be roughly speculated."

Jiang Feng looked at the current survey volume, and his eyes were thoughtful: "When the murderer threw the body, he did not use the two machine shafts at the abandoned construction site, but on the contrary, two bags of broken body pieces thrown by the murderer were found under a culvert near the highway far away from the scene. ”

"Abandoning the machine well so easy to hide, if no one falls into it, it will be difficult for anyone to find the good place to hide the body for ten and a half years, and choose a culvert that is easy to be found to throw the body, which shows that the murderer is very likely to be unfamiliar with the nearby environment, and is not familiar with the scene, indicating that this is likely to be a case of dumping the body in a different place after committing the crime, and understanding the culvert is likely to be due to the fact that he came from the road?"

Jiang Feng made his own speculation, and he continued to look through the case file.

Based on the on-site visits, the meteorological data provided by the meteorological department, the environment in which the body was thrown, and the analysis of the degree of corruption, the victim was dismembered and dumped immediately after the victim, and the time of the incident should be determined to be December 21, before the winter solstice.

......

Jiang Feng quickly obtained all the information about this case in the office.

After many years of detection, although there is no way to lock down the real murderer, there are some clues about the deceased and the murderer, which have become much clearer.

With the support of high-tech criminal technology, the experts of criminal investigation technology accurately identified the deceased as a woman who was about 21 years old, about 1.60 meters tall, medium to thin, and generally nourished from the information of the corpse parts left behind, through scientific calculation methods such as pubic symphysis and related evidence.

According to the forensic technical experts of tooth marks, the woman's right upper upper tooth has a shallow transverse groove, which is an unchanging feature of the tooth caused by dysplasia.

Identity of the murderer: Due to the heavy snow, there is no trace, but a natural refrigerator has also been formed, which makes the preservation of the corpse parts excellent, and after testing, hydrocolloids decomposed by hydroxymethyl cellulose were found on the corpse parts.

Hydroxymethyl cellulose is the main component of common gauze, after encountering blood in the body, it will quickly decompose to form a hydrocolloid with a certain viscosity, which can block capillaries, prevent wound bleeding, activate the coagulation system in the body, quickly adsorb platelets to form thrombosis, and quickly stop bleeding.

Normally, after 7-10 days, absorbable hemostatic filaments will be completely decomposed in the body, and their degradation products can be absorbed and utilized by tissues to provide nutrients for tissue cells.

However, the natural refrigerator formed by the natural heavy snow caused the process to be delayed indefinitely, and the police eventually found the substance from multiple body parts.

Jiang Feng knocked on the table, gauze is not common...... Especially two years ago, and judging from the amount of corpse degradation, the amount of gauze is beyond the reach of ordinary family medical reserves.

In this way, the scope of investigation of criminal suspects can be further narrowed to doctors or people who understand medical skills, but the criminal investigation and eradication operations for three consecutive years have not found the murderer from this scope.

Office of the Director.

Director Zheng Daodao and instructor Fang Feng were chatting with a smile.

"Lao Fang, it's been an afternoon, and these boys are still in the archives, and they can't even take care of eating, this is very energetic."

Zheng Daodao smiled: "Tell me, how long can they maintain this momentum?" Do you want people to film their energetic scene, and then take pictures of them together for comparison, so as to stimulate and stimulate these young people, and also leave a souvenir for them when they are old and young. ”

"Lao Zheng, you are too yin, when the time comes, the enthusiasm of a few young people will be all hit by you, in case it sinks like this, it will be wasted." Fang Feng shook his head and refused.

Zheng Daodao thought for a while and nodded, he said: "Cheng, those three interns are also shooting, but if they don't take it out, Jiang Feng's kid will take it out for comparison, and when the time comes, we will have a conference in the institute to watch it together." ”

"This kid's toughness is strong, and now it's just too much of the limelight, so it's no problem to sharpen it well."

Fang Feng didn't refuse this time, he nodded and said, "This is good, Jiang Feng, this kid belongs to the kind of master who doesn't see rabbits and doesn't scatter eagles, he has to grind it well to become a good jade." ”

Just when the two of them laughed and finalized how to suppress Jiang Feng's self-confidence.

The captain of the team in charge of criminal investigation ran up.

He said with a confused face: "Director...... The new intern is the Jiang Feng who solved two murder cases in a row on the first day of the report and is famous in our Lutan City police circle, he asked me for the right to check the evidence of a case two and a half years ago, do you want to give it? ”

Zheng Daodao and Fang Feng, who were originally smiling with chrysanthemums, laughed out loud when they were laughed at by the captain of the first team.

"Old Fang, you see, my suggestion just now is correct! This kid is still a little younger, and he's eager for success! It wasn't long before I went in, and I had to look at the evidence. ”

"These are all old unsolved cases that have accumulated for many years, and the province has organized a joint sweep operation by criminal investigation experts, but there are no cases that have been swept away, this kid has only been in for an afternoon, and he is anxious to see the evidence and want to solve the case."

Fang Feng nodded and agreed with what Zheng Daodao said.

Jiang Feng, this kid is a little floating.

The province's top experts jointly operated, although the experts may not have gone all out on this small case, but it was also a super luxury lineup, and the case was not solved as a result, and you kid only went in for an afternoon and wanted to solve the case?

Zheng Daodao looked at the captain of the team and said, "Give!" Give him permission! The other three new interns are also treated equally, as long as they want, then give. ”

"But you have to talk about the ugly things first, tell them, it's not more than three things, I will give them three chances, so they should cherish this hard-won opportunity."

"They only have the right to transfer evidence in three cases, and they haven't solved the case more than three times, so they will honestly come back to me to watch and monitor for three months, and then work as an internal office for two months, and a public security police for half a year."
