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

Chapter 386 Multiple Actions
Of course it's hard to check, after all, more than a year and three months have passed.

There is no real-name system in Slow Bar, so it is difficult to check.

But no matter how difficult it is, this clue is the only clue currently obtained and must be investigated.

Zhang Hui has been working for so many years and is a veteran in this field with rich experience.

"In this way, we need to start from two aspects to check the people who were in the bar last year."

"First, check the surveillance video. The surveillance video in the bar. If you check it now, you will definitely not find the information from last year. But when Wang Lili disappeared, the local police station investigated the video at that time. There should be a backup now, right?"

Zhang Lijun nodded affirmatively: "There is a backup. I checked the surveillance video. The backup of the video surveillance is in the file computer of the Criminal Police Brigade."

The case has not been solved. The surveillance video of the last place where Wang Lili disappeared was naturally reserved.

In addition to this is the last place where she disappeared, and the roadside surveillance video of the abandoned chemical plant is also preserved.

In recent years, criminal investigation work has become increasingly strict in terms of the level of detail required and the traces left behind during case handling.

Unlike in the past when handling cases, there were some surveillance videos and they were over after watching them, but now as long as there are clues, there will usually be backups.

Of course, there are also practical reasons. In the past few years, the computer configuration rate of grassroots case-handling units was not high. At that time, even if they wanted to find a place to store surveillance videos, there was no place.

It’s different now. The hard drive of the computer used for image scouting has hundreds of terabytes of storage capacity, and it can store a lot of video capacity.

"That's good. Lu Chuan, please do some hard work and be responsible for the video analysis in the bar."

Lu Chuan nodded, this is no problem.

"I'll follow up on the second way, the bar's consumption records."

Zhang Hui had also seen the surveillance video of the bar, but the resolution was not high. It was night and it was impossible to distinguish the heads of all the people entering and exiting the bar.

But when these people enter the store, they will definitely spend money.

Now that the penetration rate of mobile payment is so high, he is likely to leave clues about mobile payment, and then compare the surveillance video to identify the other party. Coupled with Sun Xiaojuan's identification, it is very likely to identify the man Sun Xiaojuan talked about. .

After determining the direction of work, several people got busy.

In fact, the workload of this investigation was not large. There were less than 200 people in and out of the bar that night.

Among them, men account for about three-fifths, and women account for about two-fifths.

The target people we are looking for are men, and three-fifths of the 200 people are probably 120 people.

According to the information provided by Sun Xiaojuan, when Wang Lili and Sun Xiaojuan played before, the target characters were relatively mature and handsome men.

The two of them were exactly the same age as Tiger and Wolf, and they didn't like young meat very much.

In Sun Xiaojuan’s words, she knows little, has no money, lacks skills, and is short of time.

Mature men are different, they have rich experience, money, and maybe because they have played a lot, most of the time they have sex for a longer period of time.

The investigation of 120 people is really not a big workload compared to the previous investigation of thousands of people in a village or a town.

In as little as one or two days, as long as three to five days, the investigation can basically be completed.

While the work in Huangzhou is in full swing, the work in Haizhou City is also in full swing.

Forensic dissection room.

When Liu Guodong, Wang Changjiang and others brought the body back, they sent it directly to the autopsy room.

Wang Changjiang and Shen Yan were dissecting a corpse. In fact, they were dissecting a corpse. It would be more appropriate to describe it as piecing together the bones.

The body was severely autolyzed and decayed. The skin and flesh on the legs and arms had basically disappeared, and the big bones could be lifted up with a gentle tug.

The inside of the torso is basically empty, covered only by a layer of waxy skin.

The hair on his head has fallen out, and his original appearance is completely unrecognizable.

"Female, the height is about 1.6 meters." There is no need to measure the length of the leg bones, and then convert it. The length of the thigh and corpse bones is about 1 meters.

"The time of death...is at least two months."

It is difficult to determine the time of death from autolyzed corpses.

This is also the corpse sample that forensic scientists least like to encounter.

The accuracy of judging the time of death is different for corpses at different stages.

For fresh corpses that have been dead for no more than 48 hours, the number of minutes since death can be accurately determined.

A powerful forensic doctor can be accurate to a few minutes.

But for a severely decomposed corpse, the number of days can probably only be accurate.

For example, Lu Chuan once judged the time of death of a corpse through the cultivation of maggots and intergenerational relationships.

For the skeletal corpse, the period of time can be accurate to the month, and the year can be determined for a long period of time.

Wang Changjiang was inspecting on one side, and Liu Guodong and others were also inspecting on the other side.

Their focus was on the boxes containing the bodies.

Different from the box containing Wang Lili's body, this box is larger and has different materials and colors.

However, the same thing is that Liu Guodong also found some soil residues in the box.

Although there is not much left due to the corpse being soaked in water, it can still be extracted.

The reason why Liu Guodong and others used the forensic autopsy room to carry out the investigation work was mainly because the box smelled too great and could not be carried anywhere else.

If it were placed in the current exploration laboratory in the basement, no one would be able to enter that place for a month.

Other than that, there are no other discoveries.

"Old Wang, are there any signs of freezing on the body?"

Wang Lili's body was refrigerated for at least a year before being dumped. Judging from the dismemberment and dumping methods, this body should be the work of the same murderer.

Therefore, this body must have been refrigerated most likely.

"This point... the body's appearance and decomposition are too severe. From the perspective of forensic examination, it is currently impossible to determine whether the body has been refrigerated."

In fact, according to Wang Changjiang's guess, the body should have been refrigerated, but the forensic examination must be based on it.

The current situation is that the forensic doctor's surface examination of the body cannot determine whether the body has been refrigerated or not.

The reason why Wang Lili's body was determined to have been refrigerated was because it had developed mildew for a second time.

The first mildew had obvious characteristics of mildew at low temperatures, so it was determined that there were traces of refrigeration.

When the second body was discovered, the search in Beishan continued.

Ren Qiang did not conduct a large-scale search through criminal investigation methods, because if the murderer did put the body into a box in Beishan, if he did so, it would most likely alert the snake.

Consumption inspection is a poor excuse.

Ren Qiang contacted the fire brigade in charge of the Beishan area.

As long as they come forward and conduct a fire inspection, Ren Qiang's people can follow.

And one advantage is that fire inspections can be very detailed, not missing any detail.

There are a total of 32 refrigerated logistics warehouses in Beishan. It will take three to five days to complete all inspections.
