Chapter 385 Changes

dinner time.

The office of Jiang Yuan's backlog class was filled with smoke, with only a few crabapples blooming regardless, exuding a cheap smell.

Everyone was turning over the files in silence.

The file was delivered in the afternoon, and no one has been in or out of the office since then.

The core of solving the backlog of cases is to read the files. If you can't understand the files, there will be no talk of solving the backlog of cases. For example, in the case in front of me, there was no scene, no witnesses, and the bodies were all decomposed. The identity of the second body could not be found, and even the body other than the arms could not be found.

The criminal police team in Luyang City is having difficulty, and I really don’t blame them.

Under such conditions, Luyang City's criminal police team actually found several clues to follow. If not, they would have given up long ago. Unfortunately, the clues were not broken through and were always cut off before they could go very far.

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

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

The criminal police team in Luyang City was delayed for almost two and a half years by the case of corpses abandoned on National Highway 805, and it took at least two to three months to devote all their efforts to it, but they failed to solve it.

Liu Jinghui, who has been out all year round, felt heartbroken when he read all the files. After reading all the files, he couldn't help but sigh: "Lu Yang has made huge compensation this time. You, Director Chai, should have escaped by now."

Meng Chengbiao also had deep experience in this aspect, but he still smiled and said: "It's not a big deal if he escapes. He was not in charge of criminal investigation before, but it is certain that Lu Yang will not make any achievements in the past few years."

"No wonder." Wang Chuanxing and others shook their heads. They all came out to work hard for their careers, and they couldn't stand not achieving results.

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

Everyone looked at it, and Liu Jinghui still said, "Then I'll start by throwing some light on things?" "You say." Jiang Yuan nodded.

"Let me ask first, the wounds on the two corpses were caused by the same knife. Is this conclusion correct?" Liu Jinghui looked at Jiang Yuan. This is the category of forensic clinical medicine. The original forensic doctor Zhai was a forensic doctor from the provincial department, and Liu Jinghui was also very familiar with it. But based on his current experience, Liu Jinghui trusted Jiang Yuan's judgment more.

Jiang Yuan nodded slightly and said: "Judging from the photos, the tool used to divide the arms of the second corpse was also the tool used to kill the first deceased. It should be a knife with a thin front end and a thicker back end, and it has more The amplitude is not very uniform, and it can be determined that it is the same murder weapon. "

"In this case, it means that the murderer killed two people a year apart and used the same murder weapon, which was not discarded in the middle. I think this matter is worth thinking about." Liu Jinghui said very seriously.

Everyone, including Jiang Yuan, had a waiting look on their faces, with no intention of thinking at all.

Liu Jinghui lowered his head and took a sip of tea. After waiting, he said: "If you let me think about it, there are actually some reasons. Let me talk about it first. The first one is that this murder weapon has additional value. For example, it is the murderer's heirloom. It could be something like an antique. Secondly, deceased No. 2 may have appeared at the first scene, or picked up the murder weapon and caused his own death."

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

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

"It's impossible to judge the current state." Even with LV6's tool mark examination and LV3's forensic clinical science, Jiang Yuan couldn't judge whether the perpetrators were the same person on the two nearly decomposing corpses. The main reason was the other party's operation itself. There is nothing specific 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 he may not be too worried about the murder weapon being found, or he needs to use the murder weapon frequently, so he did not carry out the murder. replace."

"Don't worry about the murder weapon being found, and having to use the murder weapon often, shouldn't they 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 he can't stop worrying."

Jiang Yuan was silent for a moment. He finally understood Liu Jinghui's hint. Many police officers present understood.

Meng Chengbiao impatiently played charades with them and asked: "You mean, there are still corpses? The murderer killed more than one person?" "What do you think." Liu Jinghui asked.

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

Liu Jinghui said: "It's just an idea. Whether it can be verified is anyone's guess. However, this murderer has already killed two people, and the second one was dismembered until there was only one arm left. Killing two more people should be nothing. Strange."

Tang Jia asked: "Then how to find other corpses?"

"No idea, these two corpses were discovered accidentally." Liu Jinghui said: "The No. 1 corpse was dug out when digging a sidewalk next to the national highway. The scene was also badly damaged. The arms of the No. 2 corpse were also from people passing by. In fact, the two bodies snatched from the mouths of stray dogs appeared near the national highway, which is also a rather special place. "

After a short pause, Liu Jinghui said: "The identity of the No. 1 corpse, the occupation of the deceased Li Yuan is also quite special. She has a history of selling interest, and when she disappeared, there is a high probability that she was still doing the interest selling business. This is also a high-risk group."

Liu Jinghui did not say the word serial killer, but his meaning was basically the same.

Of course, China itself does not like to use this word, and descriptions such as serial killers are easier to understand.

"Captain Jiang, I'm done here." Although Liu Jinghui's words are mostly speculations, if you follow his analysis to do the case, there is a chance to do it.

Especially the idea that there is 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 getting nothing still exists.

Jiang Yuan said "yes", to be honest, it is not easy for Liu Jinghui to come up with a different and valuable investigative idea just by reading the papers.

Let Jiang Yuan do reasoning, he can't beat Liu Jinghui.

After a brief sigh, Jiang Yuan said: "I will not talk about the information that everyone can see from the file. I think one thing that needs to be corrected is that the time of death of No. 1 should be changed."

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

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

If we just follow the evidence provided by Luyang City, the probability of solving the case will be reduced a lot.

Jiang Yuan used the LV6 time of death identification. He took out a few photos, pointed at the maggots on them, and said: "I think it can be postponed for two months. The time of death is about four months, not half a year as Luyang judged."

Liu Jinghui immediately pulled the file and read it again.
