Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Wang Song and Song Mingguang have a relatively large workload, but with the manpower support from the Tianzhou City Criminal Investigation Detachment, it should not be particularly difficult to carry out the work.

After leaving the meeting room, Lu Chuan followed Zhao Zhigao to the basement of the Criminal Investigation Detachment.

Although the floor layout of Tianzhou City Criminal Investigation Detachment is different from that of Haizhou City, the forensic autopsy laboratories are all underground.

Sun Jian, a forensic doctor from the Tianzhou City Criminal Investigation Detachment, is also an acquaintance of Lu Chuan. They have known each other for two years.

"Captain Lu, I'm going to trouble you again this time."

Sun Jiangang also attended the case analysis meeting, but he did not speak at the meeting.

"You're too polite, bro. Let's go check out the body first."

Time is running out, and Lu Chuan actually has a lot of work to do. The body needs to be dissected a second time, and because the body has been frozen, it will take some time to thaw.

"Let's go, to the corpse freezer."

Soon, Lu Chuan saw the body in the freezer.

Sun Jian explained: "From the autopsy results, we didn't get many useful clues or information."

Generally speaking, an autopsy is mainly used to determine the time and cause of death of the deceased.

However, the cause and time of death of the deceased in this case are relatively certain. In addition, because the identity of the deceased is certain, there is no need to confirm the identity of the deceased through a physical examination.

"Were there any signs of violation?"

Lu Chuan carefully observed the surface of the corpse.

"We haven't found this yet. Of course, it's possible that we haven't detected it."

Sun Jian stood next to Lu Chuan: "When the body was found, it was cooked thoroughly and some parts were already boneless."

Lu Chuan nodded. It can be seen that even in the frozen state, some muscles of the arm and finger bones have been separated from the bones, and even the skin has melted.

"Of course, the autopsy was not without any results. As for the suspect's misunderstanding, he was probably not very good at using knives and did not have a particularly good understanding of the human body structure."

Sun Jian pointed to the wound on the deceased's neck.

"The two knife wounds showed signs of multiple cuts, which was probably caused by the murderer not knowing the location of the carotid artery."

"here……"

"The knife wound here should be because the opponent didn't find the right position when he stabbed, so he didn't cut the carotid artery at the beginning, so he stabbed again."

"Has trace evidence been collected from the body?"

After observing for a while, Lu Chuan asked.

"Not this one."

Lu Chuan pondered for a moment and said, "Well, let the body melt first. I will go to the crime scene first. After I finish dealing with the crime scene, the body should be almost melted. Then I will come back to collect trace evidence from the body."

Of course Sun Jian would not object. Now that the serious crime team has accepted these cases, they can only make some suggestions. As for how to solve the cases and what needs to be done, everything now depends on the members of the serious crime team.

And no one knows Lu Chuan's strength better than Sun Jian.

Sun Jian still remembers the skeleton case that happened in Tianzhou City two years ago. It was he who conducted the identification and analysis on the skeleton at that time, but he found nothing.

To be honest, when Sun Jian knew that Lu Chuan was coming, he felt half relieved.

The forensic doctor didn't waste too much time, and it took about seven or eight hours for the body to thaw.

Lu Chuan and Zhao Zhigao went straight to Xijiagou Village in Beiwang Town. The house where the crime occurred had been surrounded.

A cordon has been set up starting from the road in front of the door.

"This is where the tire tracks were found."

Zhao Zhigao pointed to a small fenced-off area.

Close to the roadside is the section where the cement road and the dirt road connect.

The traces are still there, and Lu Chuan squatted down to study them carefully.

"Have we investigated this?"

Zhao Zhigao nodded and said, "We sent people to look for tires with similar patterns in the tire market, but we haven't found any so far."

Lu Chuan nodded: "Of course I can't find it. This tire was produced 10 years ago for a special truck tire."

"It has been discontinued for a long time, and even then this type of truck tire was only for that type of truck and was not circulated on the market."

Lu Chuan has the skills to identify and analyze tire marks. He can tell what type and age the tire is at a glance.

Moreover, based on the width of the tire pattern and the depth of the tire's tread, you can roughly determine whether there is any load.

"Oh? Captain Lu, do you know what kind of car it is?"

"Yes, it's a kind of insulated van, Changning brand. There shouldn't be many of them in stock."

Lu Chuan quickly told the purpose and brand of the van: "Well, Director Zhao, can you please notify the Tianzhou City Traffic Police Detachment and ask them to check how many Changning brand insulated vans produced 10 years ago are there in our Tianzhou City? Every one of them must be investigated thoroughly."

"Okay, okay, I'll do it right away!"

Zhao Zhigang didn't expect that Lu Chuan had just arrived at the scene and had not yet entered the yard, but had already discovered such an important clue based on a tire print.

By the way, if this tire mark was really left by the murderer's car, then wouldn't it immediately narrow down the scope of the suspects?

In fact, Lu Chuan had already seen this tire mark in the file, and he already knew what type of car this tire belonged to at that time.

It was simply because there was no way to accurately see the tire marks in the photo at the time, or how deep they were, which meant it was impossible to determine whether the van was loaded based on the situation at the scene.

So at the case analysis meeting just now, he did not reveal this information, but after the on-site investigation, he asked Zhao Zhigao to ask the traffic police detachment to investigate.

In fact, although the entire crime scene had been cleaned up by the suspect, Lu Chuan had actually discovered some clues when looking at the photos.

Now that I'm at the scene, it's a good opportunity to confirm these speculations.

First of all, Lu Chuan basically no longer pays attention to footprints or fingerprints.

The footprints left at the crime scene now are all from the investigators. They are all kinds of people, so even if the suspect was careless at the time and left one or two footprints, they are probably nowhere to be found now.

Of course, Lu Chuan believes in the ability of the Tianzhou City Criminal Investigation Detachment to trace traces, and such omissions should not occur.

After making a rough analysis of the tire marks, Lu Chuan did not rush into the room.

Instead, start observing in the yard.

The Tianzhou City Administrative Detachment conducted a relatively detailed investigation of the crime scene, and the on-site photos taken were very comprehensive.

When Lu Chuan was reading the files, he actually had a general understanding of the scene. (End of this chapter)
