Chapter 153 Strange Bloodstains (Please vote)
On the projector, eight photos were arranged in two rows, with four photos in each row.
“This is an on-site photo taken during the current survey.”
Each photo is marked with a serial number, from left to right, from No. 1 to No. 8.
Ren Qiang stood up and walked to the projector, pointing to the photo numbered No. 1: "The bag containing the broken corpses has clear traces of rolling down."
The photos at the scene were all taken by Lu Chuan.
In addition to the black plastic bag, the photo also has the direction mark of the bag rolling down.
"There are traces of the bag rolling on the ground, from east to west."
"Look at the second photo, the same traces of rolling from east to west."
“And all the bags are relatively evenly spaced, there is one every two hundred meters.”
Eight plastic bags, one every 200 meters, tumble marks from east to west.
This is all the information shown in the current survey photos.
Everyone waited with bated breath for Ren Qiang to continue his analysis.
“From this information, it can be determined that the murderer traveled from east to west in Folk Street.”
“Furthermore, the other party took a vehicle such as a car to dump the body. ”
Transportation?
Zhang Hui raised his hand: "Team Ren, why is it a vehicle such as a car?"
"Although the eight corpse bags are large in number, there are not many corpses in each bag. , an adult can definitely carry it."
"Or is it possible that the other party rides a motorcycle?"
Zhang Hui's question is very reasonable, and many criminal police officers nodded secretly.
Eight plastic bags containing corpses have been identified by forensic scientists and current investigators.
The weight is indeed not heavy, and an adult can definitely carry it.
Is there any specific reason why Ren Qiang judged that the murderer took a vehicle such as a car?
It is important to know that the vehicle used or taken by the murderer after dismembering the body is very important.
This is an important aspect of the criminal police’s subsequent investigation and analysis.
If this judgment is wrong, the investigation of the case will be completely different.
The murderer was obviously on foot, but the direction of solving the case was locked in a car. In that case, there would be no need to talk about solving the case.
Ren Qiang holds his right hand empty: "First, from the analysis of the traces of the plastic bag rolling down, the possibility of the murderer walking can be basically ruled out."
Enlarge one of the photos and Ren Qiang continues Explanation: "This is the first photo of a plastic bag taken by Lu Chuan using the central photography method."
"Look at the traces of the plastic bag rolling down. There are obvious scratches on the ground. The plastic bag rolled several times. ”
"And here," Ren Qiang pointed to a broken ice ballast on the wall of the plastic bag: "This broken ice ballast is directly above the black plastic bag. The ice ballast in other places is intact. Only this broken ice ballast should be the corpse. The bag was smashed."
"If the murderer dumped the body on foot, the body bag would most likely not have multiple rolling marks, and it would also be difficult to break the ice on the wall."
As Ren Qiang said, he picked up the garbage bag in the corner of the conference room, packed it and threw it out.
Sure enough, the bag stopped quietly in the distance, with no sign of rolling.
Ren Qiang picked up the bag and threw it out with great force: "It is unlikely that the murderer used such force to throw the body."
The bag rolled out, simulating the murderer dumping the body.
"Then why is it a car? The murderer might also be riding a motorcycle."
Ren Qiang led you to nod: "Eight bags, except for the meat buns..." Ren Qiang took a look Wang Shuai looked pale.
This child...
A bit miserable.
"Except for the bags outside the Roujiamo shop, we didn't take any first-hand photos of the corpses. The other bags were about two hundred meters apart."
"There is a possibility that the murderer deliberately created this distance. How big is it?”
Throwing a bag every two hundred meters, deliberately?
Most people shook their heads, this was unlikely. "So, I think the other person may be sitting in a car and throwing away body bags intermittently."
"If the other party is riding a motorcycle... it would be unrealistic in operation."
Qin Yong nodded. Ren Qiang's analysis made sense: "Where is the surveillance? How was the surveillance investigation?"
< br>Zhang Hui is responsible for monitoring and reviewing.
“There are two surveillance cameras in Folk Street, one on both sides of the street. We have marked all vehicles and pedestrians entering and leaving Folk Street yesterday, and are now preparing for investigation.”
All the mechanisms for detecting murder cases are very complete and the procedures are also complete.
Each group of people has a plan in advance on how to divide the work. Even if someone takes a temporary leave or is unable to participate due to other cases, there will still be AB positions for supplementary replacement.
After the incident, the investigation and interviews by the investigators, forensic doctors and other criminal police were carried out together.
In fact, although this case has a bad impact, it is not complicated from the perspective of investigation.
When corpses are dumped on the street, there are cameras on both sides of the street. Even if everyone entering and leaving the folk street is checked, the murderer can still be found.
At present, it is obviously easier to find the murderer.
"Focus on checking all the vehicles entering and exiting Folk Street last night, especially in the second half of the night!"
The work tasks were deployed quickly, and the relevant vehicle information was quickly locked.
A total of fifty-one vehicles and more than one hundred criminal police officers set off immediately.
Now surveying the office.
When the frontline criminal police attacked, Lu Chuan was not idle at the rear.
Dismemberment cases are relatively unfriendly to current investigators.
Because all the body fragments must be photographed one by one and kept in files.
Obviously, these tasks cannot be completed at the scene where the body parts were found, so we can only do it back.
Fortunately, Shen Yan also needed to examine the body, and the two of them worked together, so they didn’t feel tired while working together.
Click!
After taking another picture of a corpse, Lu Chuan straightened his back and breathed a sigh of relief when he saw that two-thirds of the work had been completed.
“The height of your dissecting table is not appropriate. I always bend over and do it, which makes me exhausted.”
Shen Yan is marking and inspecting the corpse: “That’s because you are too tall. "The height of the dissection table is regulated."
Lu Chuan smiled and continued working.
Taking a piece of corpse that looked like a waist and belly, Lu Chuan was about to take a photo, but suddenly stopped.
"What's wrong?"
"This... mark... seems a little wrong."
Lu Chuan carefully placed the body parts on the autopsy table. Under the bright light, there was a piece of Spotted stains.
The trace is brown with regular edges, like a small circle.
“Traces?”
Shen Yan looked at the traces. As a forensic doctor, Shen Yan's professionalism is unquestionable: "Is it... blood stains?"
Human blood changes greatly at different times and in different environments after death. Different.
Especially in the eyes of professionals, the size, color, and edge shape of these marks have special significance.
“Could it have been rubbed on by other body parts?”
Lu Chuan pondered for a moment and shook his head slightly: “This is a drop-shaped blood stain. I didn’t see it on other body parts. ”
The body was refrigerated at low temperature for a short period of time, so the blood in the body solidified. There was no trace of blood after the murderer dumped the body.
However, as time passed, the corpses thawed, and many of the corpses rubbed against each other and were stained with friction-shaped blood stains.
But what Lu Chuan found now was dripping blood.
In blood stain morphology analysis, dripping blood stains can determine many static on-site indicators.
