Chapter 540 A New Case Begins
Luojin City Criminal Police Detachment meeting room.

Director Xu, Wang Zhi from the Luojin City Bureau, several police officers, Cui Xiaohu and Li Haochen from the Ministry, Huang Qiangmin, Jiang Yuan and others gathered together.

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

If the atmosphere yesterday was tense, lively and united, the atmosphere in today's meeting room is lively, relaxed and happy.

It's as if a group of police dogs had a meeting yesterday, and today a group of golden retrievers had a meeting.

If it weren't for the leadership, like Pang Jidong and the others, they would want to tickle Jiang Yuan with their small eyes right now.

Of course, Xu Ju and the others are still more serious, with a more arrogant attitude for the time being.After all, the Luojin Municipal Bureau is definitely Party A this time, and everyone understands the feeling of being a father.

Taking a sip of tea, Xu Ju said with a smile: "Jiang Yuan, you don't have to be burdened. With your ability, it must be easy to do the case. Even if you get stuck, you can finish the three cases within two years. If you really do Not finished, let's discuss it again."

Wang Zhi also smiled and said: "Indeed, in fact, at the beginning, we just proposed that you provide technical support. Bureau Huang's attitude is relatively firm, and we still hope to have command power, so we agree. The case is done..."

What they were talking about was the case of "forcing" Jiang Yuan—the 110 Luo Jin Second Sexual Assault Case.

With the word Luo Jin, it indicates that the place where the case occurred was in the capital of Baijiang Province; 110 is the time when the first case occurred, on January 1 last year; the second sexual assault refers to the particularity of the case.

The perpetrator in this case adopted a relatively special way of committing the crime.He first used electric shocks to subdue the victim, then covered the victim's eyes with a cloth strip, and took him to a nearby place to sexually assault him. Then, he would hold the victim in a car and take him to another unknown location , Carried out multiple consecutive sexual assaults, and after the crime was completed, the victim was driven back to the original location and abandoned.

The locations he chose were all relatively remote areas without cameras and monitoring arrangements. The targets he chose to commit crimes were all young girls. After the sexual assault, the victim could not even identify the crime scene.

In addition to the rigorous modus operandi, the time this person committed the crime also made the police feel embarrassed. The first two crimes were committed on January 1 and January 10. According to the way the police named the project, it is easy to make people feel provocative. means.

Unfortunately, the case is not easy to detect.

Although, in a normal case, the more the perpetrator does, the more flaws there should be.But in this case, there are not many clues left by the perpetrator.

The victim was electrocuted and controlled by a rope. Not to mention his weak resistance, the clues he could provide were limited.The same is true for physical evidence, which is basically close to none.

Under such circumstances, the Luojin City Bureau has begun to try to use criminal profiling, that is, psychology has begun to solve the case.

It's just that there is still no breakthrough.

The main expectation of Xu Bureau and others for Jiang Yuan is this case.

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

Since last year, the Luojin Municipal Bureau has invested a lot of manpower and material resources in this case, and has also deliberately updated the surveillance systems in many places in the suburbs. After the fourth case appeared in the middle of the year, the police set up cards frantically, hoping to catch him with luck. to the murderer.

Although the case was not solved, the trend of the perpetrator's crazy crimes was cut off. Until today, the number of cases in this case has been fixed at 4 cases.

Even so, the Luojin City Bureau still regards this case as a disgrace. Therefore, with the end of the kidnapping case, the Luojin City Bureau, who had a little spare energy, first thought of the 110 Luojin Second Sexual Assault Case.

After Jiang Yuan received the news yesterday, he had read the materials of this case first, and only after obtaining his consent did today's meeting take place.

At this time, in front of the people of Luo Jin, Jiang Yuan gave an affirmative answer: "As long as the resources can be guaranteed, there is still a chance to solve this case."

Even though they had received a reply long ago, everyone was still beaming with joy when they heard Jiang Yuan's positive answer.

Bureau Xu hurriedly said: "There is no upper limit in this case, and the reimbursement is true. Jiang University of Forensic Medicine can rest assured."

The detachment leader is a real person, and he also negotiated with Huang Qiangmin, and said: "The four major teams can be pulled out individually, and all members can join the task force."

"The cost of the trace evidence laboratory may be higher, and the time must be up to me first." Jiang Yuan made another request.

Xu Ju and others naturally agreed.

Jiang Yuan looked at Huang Qiangmin again, and continued: "Then this case will be established first. In addition, the three agreed cases..."

"There's no need to worry about it, you just need to do the 110 case first." Director Xu became very talkative all of a sudden.

Jiang Yuan smiled and said: "When I was looking at the case on the intranet yesterday, I took a look at other cases by the way. There was a homicide case. I saw that the fingerprint evidence was quite special, so I did it by hand, and the fingerprint was also in the match. , 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 quickly picked it up, unfolded it, and saw that it was a fingerprint identification certificate, with the information of the criminal suspect attached to it, but it was a released prisoner after serving his sentence.

"Does this mean that this person is a suspect?" The detachment leader still had little contact with Jiang Yuan, so he still couldn't figure out the specific pattern.

"The bloody handprint is either a suspect or an eyewitness. Bring it back for interrogation and you will know." Jiang Yuan took a fancy to a blurry bloody handprint, so he directly put his fingerprints on it.Image enhancement LV5, two fingerprint identification skills, and temporary +4 for LV1 fingerprint identification. It only took more than half an hour to match the fingerprint.

Based on Jiang Yuan's experience, this backlog of homicide cases is considered solved.

The detachment leader was greatly shocked, and Xu Bureau was inexplicably surprised.

Huang Qiangmin smiled and said nothing. Jiang Yuan's first second-class skill was achieved during the fingerprint battle. Luojin City itself does not have such a strong fingerprint master as Jiang Yuan.

"Old Yi, let's follow up on this case." The detachment leader pointed to the captain of his second brigade.

The captain of the second brigade is a traditional old criminal policeman with a bitter and bitter look. He has sharp eyes and looks like he doesn't believe anyone, so he just nodded at the moment.

The detachment leader coughed and coughed twice, and said, "That...Jiang team, regarding the 110 case, do you have an investigation direction here?"

He wanted to ask this question just now, but was interrupted by Jiang Yuan with a fingerprint, and it would be more polite to speak again now.

Jiang Yuan naturally didn't need to hide it, and said directly: "I saw the clothes of 4 victims in the list of evidence yesterday. I think we can start from this, and first use forensic botany to delineate the location of the case."

Forensic botany connects people on the one hand and places on the other.

In forensic botany, the easiest thing to find is not a person, but a place.

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

This is not only related to the investigation stage, but also to the subsequent litigation process.

Looking at the expressions of the people, Jiang Yuan knew that they didn't quite understand the situation, so he continued: "My idea is relatively simple. When the perpetrator committed the crime, the victim's clothes should have 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 place where the murderer committed the violence for the first time should not be far from the place where the victim was shocked. The victim couldn't tell the exact time and place because of the electric shock, being blindfolded, and being frightened. Pollen No problem."

"This... Can it be found this way? After more than a year, is the pollen evidence still useful?"

Jiang Yuan only said: "For Huafen, ten years apart is pediatrics, but it depends on today's experimental operation."

The detachment leader, Xu Ju and the others just nodded their heads. Why, I don't know.
