Chapter 386 Multi-Party Action
Of course it is difficult to check, after all, more than a year and three months have passed.
Slow Shake Bar does not have a real-name system, 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 and the surveillance video in the bar. If you check it now, you will definitely not have the information from last year, but at that time 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 video surveillance backup is here. In the file computer of the Criminal Police Brigade.”
The case has not solved the surveillance video of the last place where Wang Lili disappeared at that time, so naturally there are reservations.
In addition to the last place where she disappeared, 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.
It’s not like handling cases in the past, where there were some surveillance videos, and they were over after watching them, but now as long as there are clues, they usually have 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 you 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 a storage capacity of hundreds of tons, and it can store a lot of video capacity.
“That’s good, Lu Chuan, please come and work hard and be responsible for the video analysis in the bar.”
Lu Chuan nodded, this is no problem.
"I will follow up on the second route, the consumption record of the bar."
Zhang Hui also saw the surveillance video of the bar, but the resolution was not high. It was night again. It's unlikely to be able to distinguish the heads of all the people entering and leaving 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 lock the identity of the other party. Coupled with Sun Xiaojuan's identification, it is very likely to lock Sun Xiaojuan. The man he spoke of.
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.
The proportion of men here is about three-fifths, and the proportion of women is about two-fifths.
The target people we are looking for are men, and three-fifths of the 200 people are probably 120 people.
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, it means little knowledge, no money, insufficient skills, and short time.
Mature men are different, they have rich experience, money, and maybe because they have played more, most of the time is longer.
The investigation of 120 people is really not a big workload compared to the past, when murder cases were often investigated by tens of thousands of people in a village or a town.
The investigation can be basically completed in as little as one or two days, or as long as three to five days.
While the work in Huangzhou is in full swing, the work in Haizhou City is also in full swing.
Forensic autopsy 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 corpse 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 lost.
"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 the corpse bones is about 1.6 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 doctors least like to encounter.
For corpses in different stages, the accuracy of judgment and time of death is different.
Fresh corpses that have been dead for less than 48 hours can accurately determine the number of minutes since the corpse died.
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 determined the time of death of a corpse through the cultivation of maggots and intergenerational relationships.
The skeletal corpse can be accurate to the month for a period of time, and the year can be judged 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 box containing the body.
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 elsewhere.
If it were placed in the current survey 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. So the method of dismemberment of this body Judging from the method of dumping the body, it should be the same murderer.
Therefore, this body must have been refrigerated with a high probability.
"This point... the body's appearance and decomposition are too serious. From the perspective of forensic examination, it is 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 showed 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 work 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, he would probably 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 the fire inspection can be very detailed, not missing any detail.
There are a total of thirty-two refrigerated logistics warehouses in Beishan. After all inspections, three to five days are enough.
