Chapter 268: Scoring

"Look at this case, how about it? There are many footprints at the scene. Although there is no blood, it happened in the wild, and there are quite a lot of traces." Liu Jinghui handed a file to Jiang Yuan.

Jiang Yuan glanced at it twice, confirmed it was a case he had seen, and said, "70 points." "I give it 80 points, so that's 150 points, currently ranked third." Liu Jinghui made a note at his hand and then put the file back properly.

On this side, Jiang Yuan handed a case to Liu Jinghui and said, "I give this one 75 points."

"I'll give it 60. It's another case in a mountainous area, running around until you're exhausted, and there are no eyewitnesses. I estimate that evidence collection won't be done too well either." Liu Jinghui said while making records, and added, "135 points, this ranks sixth. Our scoring segments are a bit dense."

"Most cases can actually be done." Jiang Yuan said, "How about we look at two more cases and then start working."

"That 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.

His own group of police officers, who pride themselves on being elites, were sitting at the other end of the conference room, looking over there eagerly.

"What are those two doing?" Yu Wenshu asked. "Screening cases." Wan Baoming said. "I heard them scoring."

"En, they are scoring the cold cases based on their personal preferences and their own perceived difficulty of the cases, and then working on the case with the highest combined score."

Yu Wenshu nodded upon hearing this, then looked left and right, and said, "Those with mobile phones, put your phones on the table. Filming videos or recording audio is not allowed in the conference room. You all understand the confidentiality regulations, right?"

"They are all sensible; it's impossible for them to do these things." Wan Baoming said as he stood up: "I'll help you check."

He checked the few mobile phones on the table before smiling and saying, "Those who have nothing to do, look at the files; don't touch your phones casually."

Everyone then huddled obediently in their chairs, watching Jiang Yuan and Liu Jinghui estimate scores.

Jiang Yuan and Liu Jinghui had also looked at a stack of files. At this time, they stopped, took out the file ranked first again, and confirmed it.

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

A murder case from two years ago is also a cold case, but compared to cold cases from a long time ago, the case-solving probability of this kind of case will be higher.

Yu Wenshu was eager for someone to help work on cases. No matter which case Liu Jinghui and Jiang Yuan chose, he only had support to offer.

Coming over this time, looking at the case, Yu Wenshu said: "This pervert, we struggled for three months... Do you have any ideas?"

In a provincial capital city like Changyang, it is possible to solve every murder case, but in reality, it is unlikely to be achieved.

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

In his memory, this case looked more like a random crime, and no key physical evidence like fingerprints or DNA was left at the scene. And after the victim was cruelly killed, very few clues were extracted.

Of course, cold cases that cannot be solved must have a certain complexity. In a place like Changyang City, only after all clues are cut off will manpower and other resources be reduced.

Liu Jinghui and Jiang Yuan looked at each other, and Liu Jinghui said, "I'll speak first."

"Good." Jiang Yuan moved the other files to the side and put the 7.2 case file in the middle.

A clever young person had already come over to help clear the space.

Liu Jinghui opened his notebook, looked at it twice, and said: "The time of this case was approximately 1:20 AM on July 2nd. The victim, Liu Juan, female, was robbed, raped, and killed on her way home from work. From the forensic report, she had multiple injuries on her chest and back. At the same time, the victim's chest, perineum, and inner thighs all had obvious traces of being bitten or sucked..."

After speaking roughly, Liu Jinghui paused and said, "From the criminal behavior of the murderer, I think the murderer's main purpose was rape, which is a 'pornographic' crime. Moreover, the criminal has certain sexual psychological disorders. I think we can start from this angle."

Liu Jinghui pointed at the file and continued: "First, the victim had 32 knife wounds, and there were 11 fatal wounds. This is not a normal way of killing, but more in line with sexual sadism. The multiple bite marks on the victim are also the same; they are typical lover-biter marks."

Yu Wenshu nodded and said, "This line of thinking is consistent with the judgment of the special task force at the time. I still roughly remember that the conclusion given by the special task force at the time was that sexual sadism is the murderer's main means of exerting abuse and violence on female victims for sexual excitement, stabbing women and insulting them, leading to disability and death..."

Everyone looked sideways at Yu Wenshu's performance.

Everyone already knew very well that the detachment captain had a photographic memory, but the detachment captain just didn't remember this matter.

Liu Jinghui coughed twice and continued: "I think we can create a criminal behavior profile for the murderer through this series of behaviors, which may be helpful for the subsequent screening or investigation. Jiang Yuan?"

Criminal behavior profiling is similar to the criminal profiling of the FBI in American dramas, but it won't be very long. It is usually a judgment of some characteristics of the murderer, which is helpful for the subsequent screening or investigation.

Liu Jinghui obviously needed a little time to do this, but he was obviously confident.

Jiang Yuan then took over and said, "I looked at some photos of the scene and felt that the murderer's footprints could provide some help."

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

"Yes. And cheap slippers." Jiang Yuan arranged the photos he had just taken out in order on the table and said, "The shoe prints at the scene have strip-like patterns and have the characteristics of small injection holes. The soles are severely worn and have characteristics of defects and cracks. This shows that the soles are most likely made of PVC material, and the slippers have been worn for a long time."

"This shows that the murderer's living conditions are not very good." Yu Wenshu also simply deduced one step.

Jiang Yuan nodded and added, "In the process of committing the crime, the murderer stepped into the flower bed by the roadside. Added to the bloody footprints at the scene, it can be seen that at the time of the crime, the murderer was about 25 years old and had a lighter weight..."

Liu Jinghui, who had already started writing key points on the side, looked up and said, "I agree with this. Most of the causes of sexual sadism are related to family factors. They often grow up in a circle surrounded by the opposite sex, with a family atmosphere where the yin is strong and the yang is weak, and the mother-son relationship is poor or overprotected. For this type of person, the formation time of sexual psychological disorders is generally around 16 years old, and the crime usually occurs 8 years later. That is, around 24 years old. Jiang Yuan's judgment of the time is very reasonable."

Everyone's emotions were also mobilized.

Jiang Yuan said, "The footprints at the scene can also provide some relatively valuable information. I initially judged that the murderer's height is under 160 cm, most likely only about 157 cm..."

Everyone was refreshed.

"This height filters out a lot of people at once, right?" Tang Jia said in a low voice, then added, "However, many boys wear height-increasing shoes, right."

"The murderer was wearing slippers at the time." Wang Chuanxing reminded.

Liu Jinghui suddenly stood up, waved his hand, and said, "I originally had a judgment that the crime location was in the old city of Changyang City, where the flow of people is actually not small. The criminal was bold and dared to wear slippers to commit the crime 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 repeat offender is very high. Moreover, it is very likely that he was released not long ago."

Looking at Jiang Yuan, Liu Jinghui said, "If the murderer's height is really under 160 cm, combining the factors of repeat offenders and age, plus the time of release, I estimate the list will not be very long."

Yu Wenshu nodded repeatedly upon hearing this. After Liu Jinghui finished speaking, Yu Wenshu directly clapped his hands and said to a group of people, "What are you still thinking about? One person is responsible for one province; list the names first. The current age is between 23 and 28, height under 160 cm, released within one year before the crime."

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

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

They hadn't even started to exert their strength yet. ===== CHAPTER 269 =====
