Chapter 513: New Case Starts

Luojin Municipal Criminal Police Detachment Conference Room.

Xu Ju of the Luojin Municipal Bureau, Wang Zhi, and many police officers, together with Cui Xiaohu and Li Haochen from the ministry, as well as Huang Qiangmin and Jiang Yuan, gathered together.

Entering the conference room, Jiang Yuan could feel the atmosphere different from yesterday.

If yesterday's atmosphere was tense, lively, and united, today's conference room atmosphere was lively, relaxed, and happy.

It was as if yesterday was a meeting of police dogs, and today was a meeting of golden retrievers.

If it weren't for the leaders in charge, people like Pang Jidong would have wanted to use small eyes to scratch Jiang Yuan's itch.

Of course, Xu Ju and others were still the relatively serious kind, temporarily having a relatively arrogant posture. After all, the Luojin Municipal Bureau was the absolute party A this time, and the feeling of being a father, those who understand understand.

Drinking tea easily, Xu Ju smiled: "Jiang Yuan, don't have a burden. With your ability, doing cases must be easy. Even if you get stuck, it will be fine to finish the three cases within two years. If you really can't finish it, let's discuss it again."

Wang Zhi also smiled and followed: "Indeed, in fact, at the beginning, we proposed that you provide technical support. Director Huang's attitude was relatively firm, hoping to have command, and we agreed. In short, just solve the case..."

What they were talking about was the case "force-fed" to Jiang Yuan—the 110 Luojin secondary sexual assault case.

With the word Luojin, it shows that the location of the case occurred in the provincial capital of Baijiang Province; 110 is the time when the first case occurred, on January 10 last year; secondary sexual assault refers to the particularity of the case.

The criminal of this case uses a relatively special way of committing the crime. He first uses electric shock to subdue the victim, then uses a cloth strip to cover the victim's eyes, holds her to the vicinity to commit sexual assault, then he will hold the victim on the car, take her to another unknown location, and commit multiple sexual assaults. After the crime is completed, he drives the victim back to the initial location and abandons her.

The locations he chose were relatively remote areas, without cameras and monitoring layouts. The targets he chose were young girls. After round-trip sexual assault, the victim couldn't even point out the crime scene.

In addition to the rigorous modus operandi, the time of the criminal's crime also made the police feel embarrassed. The first two crimes were on January 10 and January 19, respectively. According to the way the police named the special case, it was easy to make people feel the meaning of provocation.

It just so happened that the case was not easy to solve.

Although it is said that for normal cases, the more the criminal does, the more flaws there should be. But in this case, there were really not many clues left by the criminal.

The victim was shocked and controlled by ropes. Not to mention weak resistance, the clues that could be provided were also very limited. Physical evidence was also the same, and effective physical evidence was basically close to zero.

Under these circumstances, the Luojin Municipal Bureau had already begun to try to use criminal profiling, which is psychology, to solve the case.

It's just that there was still no breakthrough.

Xu Ju and others had the main expectation for Jiang Yuan, which was this case.

Rape is one of the eight major serious cases, and the nature of serial rape is even worse. Plus the victims were all middle school girls, the destructive power of this case to society was far greater than imagined.

Since last year, the Luojin Municipal Bureau had invested a lot of manpower and material resources in this case, and specially updated the monitoring systems in many places in the suburbs. After the fourth case appeared in the middle of the year, the police set up checkpoints crazily, hoping to catch the murderer by luck.

Although the case was not solved, the trend of the criminal committing crimes crazily was cut off. Until today, the number of crimes in this case had been fixed at 4.

Despite this, the Luojin Municipal Bureau still regarded this case as a shame. Therefore, with the end of the kidnapping case, the Luojin Municipal Bureau, which had a little spare power, first thought of the 110 Luojin secondary sexual assault case.

Jiang Yuan had already read the case data after receiving the news yesterday, and it was only after his consent that today's meeting was held.

At this time, in front of the Luojin people, Jiang Yuan gave a positive reply: "As long as resources can be guaranteed, there is a chance to solve this case."

Even if they had already received a reply, everyone was still happy to hear Jiang Yuan's positive answer.

Xu Ju hurriedly said: "This case has no upper limit, report and reimburse, Wu Wu Fa Yi Jiang can rest assured."

The detachment leader was a practical person, and he had already talked to Huang Qiangmin, so he said: "The Fourth Brigade can be pulled out separately, and everyone will join the special task force."

"The expenses of the trace evidence laboratory might be a bit large, and the time must be tight for me first." Jiang Yuan raised requirements again.

Xu Ju and others naturally agreed.

Jiang Yuan looked at Huang Qiangmin again, and then said: "Then let's build this case first. In addition, the three agreed cases..."

"That's not urgent, you just do the 110 case first." Xu Ju suddenly became extremely easy to talk to.

Jiang Yuan smiled and said: "When I looked at the case on the intranet yesterday, I happened to look at other cases. There was a cold case. I saw that the fingerprint evidence was quite special, so I did it by the way. The fingerprints were also matched. Let's send someone to follow up later."

Jiang Yuan took out an A4 paper that had been folded several times from his pocket and handed it forward.

The detachment leader hurriedly took it, unfolded it, and saw a fingerprint identification report directly. Below it was attached the information of the matched criminal suspect, but it was a criminal who had been released from prison.

"Meaning this person is a suspect?" The detachment leader had less contact with Jiang Yuan, so he still didn't have a specific mode.

"Bloody handprint, if not a suspect, then a witness. Bring it back and interrogate it to know." Jiang Yuan just took a fancy to a blurred bloody handprint, so he went directly to the fingerprint. Image enhancement LV5, then two fingerprint identification skills, and then a temporary +1 to the LV4 fingerprint identification. In just over half an hour, the fingerprint was matched.

In Jiang Yuan's experience, this cold case was considered solved.

The detachment leader was shocked, and Xu Ju was surprised.

Huang Qiangmin smiled without saying a word. Jiang Yuan's first second-class merit was killed during the fingerprint battle. Luojin City itself did not have a fingerprint master as strong as Jiang Yuan.

"Old Yi, you guys follow up on this case." The detachment leader pointed to his Second Brigade captain.

The captain of the Second Brigade was an old criminal police officer with a traditional bitter and deep appearance. His eyes were sharp, and he didn't believe anyone. At this moment, he just nodded and agreed.

The detachment leader coughed twice again and said: "That... Team Leader Jiang, regarding the 110 case, do you have any investigation direction?"

He just wanted to ask this question, but was interrupted by Jiang Yuan with a fingerprint. Now that he spoke again, it seemed more polite.

Jiang Yuan naturally didn't need to cover up, and said directly: "I saw in the evidence list yesterday that there were clothes of 4 victims. I think we can start from this piece, first use forensic botany to circle the location of the case."

Forensic botany, one side connects to people, and the other side connects to locations.

Using forensic botany, what is easiest to find is not people, but places.

And in this serial rape case, the crime scene has never been found, which is a big problem.

This not only concerns the investigation stage, but also the subsequent litigation link.

Jiang Yuan looked at everyone's expressions and knew they didn't understand the situation yet, so he continued: "My idea is relatively simple. When the criminal commits the crime, the victim's clothes should come into contact with the first scene and the second scene. And the contact time should not be short. If there are four cases, maybe we can find a pattern."

"Second. The location where the murderer first committed violence should not be far from the position where the victim was shocked. Because of the electric shock, being blindfolded, and being frightened, the victim cannot say the accurate time and location. Pollen doesn't have this problem."

"This... can this be found? After more than a year, is pollen evidence still useful?" The detachment leader just felt that the more he heard, the more unbelievable it was.

Jiang Yuan only said: "For pollen, a gap of ten years is a minor case. However, it depends on today's experimental operation."

The detachment leader and Xu Ju and others nodded. Why, they didn't know. ===== CHAPTER 514 =====
