civil forensic

dinner time.

In the office of Jiang Yuan's special class for accumulated cases, there was smog, only a few crabapple flowers blooming regardless, exuding a cheap smell.

Everyone was silently flipping through the files.

The files were delivered in the afternoon, and no one has been in or out of the office since.

The core of solving accumulated cases is to read the files. If you can't understand the files, you can't talk about solving accumulated cases.Like the case in front of me, there is no scene, no witnesses, and the corpses are all decomposed. The identity of the second corpse cannot be found, and even the body other than the arm cannot be found.
The criminal police team in Luyang City is having a hard time, and I really don't blame them.

Under such conditions, the criminal police team in Luyang City actually found several clues to follow up. If not, they would have given up a long time ago.It is a pity that the clues have not been broken through, and they are always cut off before going far.

In fact, any clues that cannot directly lead to the truth will have such problems.

It is normal to get stuck while walking, but such clues are the most consuming of manpower and material resources.

The criminal police team in Luyang City was dragged down by the 805 National Highway for almost two and a half years, and it took at least two or three months to devote all its efforts, but if it failed to solve it, it failed to solve it.

Liu Jinghui was away all the year round, and what he saw was distressing. After reading all the files, he couldn't help but sigh with emotion: "Lu Yang has lost a lot of money. You, Director Chai, must have escaped."

Meng Chengbiao also had a deep understanding of this aspect, but he still smiled and said, "It's not impossible to escape, and he was not in charge of criminal investigation before, but it is certain that Lu Yang has not achieved results in the past few years."

"No wonder." Wang Chuanxing and others shook their heads.They are all out to fight for their careers, and they can't bear things like not getting results.

"What do you think?" Jiang Yuan had already finished reading the papers, and seeing that everyone was about to start chatting, he simply started the discussion.

Everyone looked at it, and it was still Liu Jinghui who said, "Then I'll throw bricks to attract jade first?" "You say." Jiang Yuan nodded.

"Let me ask first, the wounds of the two corpses were caused by the same knife. Is this conclusion correct?" Liu Jinghui looked at Jiang Yuan. This is the field of forensic medicine. The original forensic doctor Zhai was the forensic doctor of the provincial department, and so was Liu Jinghui Very familiar, but based on current experience, Liu Jinghui trusts Jiang Yuan's judgment more.

Jiang Yuan nodded slightly, and said: "From the photos, the tool used to split the arm of the second corpse is also the tool used to kill the first deceased. It should be a knife with a thin front end and a thick rear end. The amplitudes of the two are not very uniform, so it can be determined that they are the same murder weapon.”

"Since this is the case, it means that the murderer killed two people a year apart, using the same weapon and not throwing it away. I think this matter is worth thinking about." Liu Jinghui said very seriously.

Including Jiang Yuan, everyone had a waiting look on their faces, showing no intention of thinking at all.

Liu Jinghui lowered his head and took a sip of his tea. After waiting, he said again: "If I think about it, there are actually some reasons. Let me talk about it first. First, this murder weapon has additional value, such as the murderer's heirloom. It might be an antique or something. Second, the No. [-] deceased may have appeared at the first scene of No. [-], or picked up the murder weapon, and then caused his own death.”

Jiang Yuan's eyebrows twitched, and said: "It means that the murderer may not be one person, but two people used the same murder weapon?"

"It's just a possibility. Can you tell if the knife holder is alone?" Liu Jinghui asked Jiang Yuan expectantly.

"Current status, I can't judge." Even if Jiang Yuan has LV6 tool trace inspection and LV3 forensic clinical science, there is no way to judge whether the perpetrator is the same person on two corpses that are close to decay. The main reason is the operation of the other party itself. No specificity, and too little information.

Liu Jinghui nodded and said: "In this case, the probability of the third possibility is higher. The murderer may not care too much, or is not too worried about the murder weapon being found, or he needs to use this murder weapon frequently, so no further investigation is carried out. replace."

"Don't worry about the murder weapon being found, and needing to use the murder weapon frequently, shouldn't it be two possibilities?" Jiang Yuan asked.

Liu Jinghui blinked his eyes, and said, "It's also possible that he often needs to use murder weapons, so I can't worry about it."

Jiang Yuan was silent for a while, he understood Liu Jinghui's hint.Many police officers present understood.

Meng Chengbiao impatiently played riddles with them and asked, "It means there are still corpses? The murderer killed more than one person?" "What do you think?" Liu Jinghui asked back.

"Your idea is bold enough." Meng Chengbiao did not answer directly, took a cigarette from the table, put it in his mouth, and pondered.

Liu Jinghui said: "It's just an idea, whether it can be verified or not is another matter. However, the murderer has already killed two people, and the second one is still dismembered until only one arm is left. It should be fine to kill two more people." Strange."

Tang Jia asked, "Then how did you find the other corpses?"

"No idea, these two corpses were discovered by accident." Liu Jinghui said: "The No. [-] body was dug out when digging a sidewalk beside the national highway, and the scene was also damaged enough. The arm of the No. [-] body was also passed by. The two bodies that were snatched from stray dogs actually appeared near the national highway, which is quite a special place.”

After a short pause, Liu Jinghui continued: "The identity of Corpse No. [-] and the occupation of the deceased Li Yuan are quite special. He has a history of selling money, and when he disappeared, there is a high probability that he was still doing money selling. This is also a high-risk group. .”

Liu Jinghui didn't say the word serial killer, but that's basically what he meant.

Of course, the country itself doesn't like to use this term, and descriptions like serial murderers are easier for people to understand.

"Captain Jiang, I'm done talking here." Liu Jinghui's words were mostly speculative, but if the case is handled according to his analysis, there is a chance that it will be settled.

Especially the idea of ​​another corpse, if you believe this judgment, once it comes true, you will definitely be able to gain a lot of information.Of course, the possibility of no harvest still exists.

Jiang Yuan said "En", speaking of it, it was really not easy for Liu Jinghui to come up with a different and valuable investigative idea just by reading the papers.

If Jiang Yuan was asked to reason, he would not be able to deal with Liu Jinghui.

After a short sigh, Jiang Yuan said: "I won't talk about the information that everyone can see from the dossier. I think the point that needs to be corrected is that the death time of No. [-] should be changed."

"How to change it?" Liu Jinghui and others immediately became interested.

If the time of death is changed, the direction and content of Luyang City's investigation will naturally change.For now, change is an absolute good thing.

If you just follow the evidence given by Luyang City, the probability of solving the case will be greatly reduced.

Jiang Yuan used LV6's time of death identification. He took out a few photos, pointed to the maggots on them, and said, "I think it can be delayed by two months, and the time of death is about four months, not half a year as judged by Lu Yang. .”

Liu Jinghui immediately pulled the file and read it again.
