Chapter 278 Scoring
"How about this case? There are many footprints at the scene. Although there is no blood, there are many traces of what happened in the wild." Liu Jinghui handed a file to Jiang Yuan.

Jiang Yuan glanced at it twice, confirmed that he had seen the case, and said, "70 points."

"I gave 80 points, so it's 150 points, and now it's ranked third." Liu Jinghui marked it on his hand, and then put the file back carefully.

Here, Jiang Yuan handed a case to Liu Jinghui and said, "I will give 75 points for this."

"I'll give it 60. It's another case in a mountainous area. I'm exhausted after running all the way, and there are no witnesses. I don't think the collection of evidence is very good." Liu Jinghui said while taking notes, and said: " 135 points, which ranks sixth, and the divisions we gave are a bit dense."

"Most cases can actually be done." Jiang Yuan said: "If you don't want to look at two cases, just do it."

"It works."

……

When Yu Wenshu came over, he saw Jiang Yuan and Liu Jinghui whispering to each other on the other side of the conference room.

This group of self-proclaimed elite police officers were sitting at the other end of the meeting room, looking over there eagerly.

"What are you two doing?" Yu Wenshu asked.

"Case selection." Wan Baoming said.

"How about I listen to the grade?"

"Well, according to their personal preferences and the degree of difficulty they think the cases are, they will score the accumulated cases, and then do the case with the highest score after the merger."

Yu Wenshu listened and nodded, then looked around, and said: "A few people with mobile phones, put the mobile phones on the table, video recording and recording are not allowed in the meeting room, you understand the confidentiality regulations."

"It's all sensible, it's impossible to do such things." Wan Baoming said and stood up: "Let me take a look for you."

He checked all the mobile phones on the table, and then said with a smile: "Look at the file if you have nothing to do, don't use your mobile phone casually."

So everyone nestled in the chairs obediently, and it was up to Jiang Yuan and Liu Jinghui to estimate the score.

Jiang Yuan and Liu Jinghui had also read a stack of files, and stopped at this moment, and took out the first file again to confirm it.

Liu Jinghui shouted: "Captain Yu, let's do this case first, the one from the year before last, the 7.2 rape and murder case, under the Victory Bridge."

The murder case two years ago is also a backlog, but compared to the backlog of a long time ago, the probability of detection of this kind of case is a little higher.

Yu Wenshu longed for someone to help with the case, no matter which case Liu Jinghui and Jiang Yuan chose, he could only support it.

Coming over now, after looking at the case, Yu Wenshu said, "You pervert, we've been tossing about for three months... Do you have an idea?"

In a provincial capital city like Changyang City, it is possible to solve the murder case, but it is actually impossible.

Regarding the case from the year before last, Yu Wenshu was also a little curious about why both Jiang Yuan and Liu Jinghui gave it high marks.

As far as he can remember, this case was more like a random crime, and no key physical evidence of fingerprints and DNA was left at the scene.After the victim was brutally killed, very few clues were extracted.

Of course, the backlog of cases that cannot be solved must have certain complexity. In places like Changyang City, only after all clues are cut off will they shrink manpower and other resources.

Liu Jinghui and Jiang Yuan looked at each other, Liu Jinghui said: "Let me talk first."

"Okay." Jiang Yuan took the other files aside, and put the file of Case 7.2 in the middle.

The clever young man has come to help vacate the cage and change the bird.

Liu Jinghui opened his notebook, took a look, and said, "The time of this case was around 7:2 am on July 1. The victim, Liu Juan, was a woman who was robbed and raped on her way home from get off work. And killed. According to the forensic report, she suffered multiple wounds on her chest and back, and at the same time, the victim's chest, perineum and thighs all had obvious signs of being bitten or sucked..."

After speaking briefly, Liu Jinghui paused and said, "From the perspective of the murderer's criminal behavior, I think the murderer's main purpose of committing the crime is rape, that is, a "pornographic" crime. Moreover, the criminal has certain sexual and psychological barriers. . I think we can start from this angle.”

Liu Jinghui clicked the dossier, and continued: "First of all, the victim had 32 stab wounds, including 11 fatal wounds. This is not a normal way of killing, but more in line with sexual sadism. The victim's body has multiple bite marks Also, it's a typical lover-biter, lover-biter."

Yu Wenshu nodded and said: "This line of thinking is in line with the original judgment of the task force. I still roughly remember that the conclusion given by the task force at that time is that sexual sadism is the result of the perpetrators inflicting abuse and violence on female victims as sexual arousal. The main method is stabbing women and insulting individuals to cause disability and death of the other party..."

Everyone squinted at Yu Wenshu's performance.

The detachment leader has a photographic memory for this incident, everyone is already very clear, but the detachment leader alone does not remember this incident.

Liu Jinghui coughed twice, and continued: "I think, through this series of behaviors of the murderer, we can give a description of the murderer's criminal behavior, which may help solve the case. Jiang Yuan?"

The description of criminal behavior is similar to the criminal profile of Fobole in the American TV series, but it is not very long. It usually judges some characteristics of the murderer, which is helpful for the subsequent investigation or investigation.

Liu Jinghui obviously needs some time to do this, but he is obviously already confident.

Jiang Yuan then took over and said: "I saw some photos of the scene, and I feel that the murderer's footprints can provide some help."

Yu Wenshu's memory immediately came back, and said, "The murderer was wearing a pair of slippers?"

"Yes. And they are cheap slippers." Jiang Yuan arranged the photos he had just taken out on the desktop in order, and said: "The shoe prints on site are striped patterns, and have the characteristics of small injection holes. The soles are severely worn, and there are Defects and cracks indicate that the soles are most likely made of PVC, and the slippers have been worn for a long time.”

"It means that the murderer's living conditions are not very good." Yu Wenshu also reasoned a step further.

Jiang Yuan nodded, and said: "During the crime, the murderer stepped on a flower bed by the side of the road, and with the bloody footprints on the scene, it can be seen that the murderer was about 25 years old at the time of the crime, with a relatively light weight. ..."

Liu Jinghui, who was already writing the main points beside him, raised his head and said: "I agree with this. Most of the causes of sexual sadism are related to family factors, often growing up in a circle surrounded by the opposite sex, the family atmosphere is full of yin and yang, and the relationship between mother and child is not good. Or a state of overprotection. For such people, the formation time of sexual psychological disorders is generally around 16 years old, and most crimes occur after 8 years. That is, around 24 years old, Jiang Yuan's judgment is very reasonable."

The emotions of the people were also aroused.

Jiang Yuandao: "The footprints at the scene can also provide some valuable information. My preliminary judgment is that the murderer's height is below 160 centimeters, and the probability is only about 157 centimeters..."

Everyone was refreshed.

"With this height, many people will be screened out at once." Tang Jia finished in a low voice, and then said: "However, many boys wear height-enhancing shoes."

"The murderer was wearing slippers." Wang Chuanxing reminded.

Liu Jinghui stood up suddenly, waved his hands, and said, "I originally had a judgment. The crime took place in the old city of Changyang City. The traffic flow is actually not small. The criminals were bold enough to wear slippers and commit crimes when the conditions were not very mature. , I think it is very likely that he has a criminal record, considering his background factors, I think the possibility of a criminal conviction is very high. And, it is likely that he will not be released for a long time."

Looking at Jiang Yuan, Liu Jinghui said: "If the murderer's height is really lower than 160 centimeters, considering the factors of previous convictions and age, plus the time of release, I don't think the list will be very long."

Yu Wenshu nodded frequently, and when Liu Jinghui finished speaking, Yu Wenshu clapped his hands and said to a group of people: "What else are you thinking about? One person is in charge of a province, so make a list first. The current age is 23 to 28 years old Between 160 centimeters and under [-] centimeters, released within one year before the incident."

The list of provinces may be very long, but Yu Wenshu believes that there will not be many people who really meet the requirements, and the murderer is likely to come from Shannan Province or surrounding provinces.

Jiang Yuan and Liu Jinghui looked at each other, neither of them expected that the effect would be so prominent after confirming each other.

They haven't started working out yet.
