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

Chapter 153 Strange Bloodstains (Ticket Request)

On the projector, eight photos are arranged in two rows of four photos.

"This is an on-site photo taken by the current survey."

Each photo is marked with a serial number, from left to right, from number one to number eight.

Ren Qiang got up and walked to the side of the projector, pointing to the photo labeled No. [-]: "The bag containing the dismembered body, the traces of the roll are very clear."

The photos at the scene were all taken by Lu Chuan.

In addition to the black plastic bags, there are also markings in the direction in which the bags tumbled.

"There were signs of the bag rolling down on the ground, going from east to west."

"Let's look at the second photo again, the same traces of rolling from east to west."

"And the distance between all the bags is relatively uniform, there is one every 200 meters."

Eight plastic bags, one every 200 meters, were rolled from east to west.

That's all the information shown by 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 direction of the murderer's travel on Folk Street is from east to west."

"Moreover, the other party is taking a car or other means of transportation to throw the body."

Transportation?
Zhang Hui raised his hand: "Ren Zu, why is it a vehicle or something?"

"Although there are a lot of eight corpse bags, there are not many body parts in each bag, and an adult can carry them on their backs."

"Or, it's also possible that the other party is riding a motorcycle?"

Zhang Hui's question was very reasonable, and many criminal policemen nodded secretly.

Eight plastic bags of shredded corpses have been identified by the forensic doctor and the current survey.

The weight is really light, and an adult can carry it on its back.

Ren Qiang judged that the murderer took a car or other means of transportation. Is there any specific reason for it?

You must know that the vehicle used or taken by the murderer is very important after dismembering the body and throwing the body.

It is an important aspect of the criminal police's next investigation and analysis.

If this judgment is wrong, then the detection of the case will be completely different.

The murderer was clearly on foot, but the direction of solving the case was locked in the car. In that case, there would be no need to talk about solving the case.

Ren Qiang clasped his right hand: "First, from the analysis of the traces of the plastic bag rolling down, the possibility of the murderer walking can be basically ruled out."

Enlarging one of the photos, Ren Qiang continued to explain: "This is the first photo of a plastic bag taken by Lu Chuan with the central photography method."

"Everyone can see the traces of the plastic bag rolling down. There are obvious scratches on the ground, and the plastic bag has been rolled several times."

"And here," Ren Qiang pointed to a piece of broken ice on the wall of the plastic bag: "This piece of broken ice is right above the black plastic bag, and the ice in other places is intact, only here is broken, it should be a corpse." The bag was smashed."

"If the murderer threw the body on foot, there is a high probability that the body bag will not have many rolling marks, and it will be difficult to break the ice on the wall."

Ren Qiang said while picking 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, without any signs of rolling over.

Ren Qiang picked up the bag and threw it out with great force: "It is impossible for the murderer to throw the body with such force."

The bag tumbled out, simulating the situation of the murderer throwing the body.

"Then why is it a car? The murderer may also be riding a motorcycle."

Ren Qiang took you to nod: "Eight bags, except for the Roujiamo..." Ren Qiang glanced at the pale Wang Shuai.

this kid...

It's a bit miserable.

"Except for the bags outside the Roujiamo shop, we didn't take first-hand photos of the corpses. The other bags were about 200 meters apart."

"How likely is it that the murderer deliberately created this distance?"

Throwing a bag every 200 meters, deliberately?

Most people shake their heads, it's not very likely.

"So, I think the other party may be sitting in the car, throwing body bags intermittently."

"If the other party is riding a motorcycle...it's not realistic to operate."

Qin Yong nodded, Ren Qiang's analysis made sense: "What about monitoring, how is the monitoring and investigation?"

Zhang Hui is responsible for monitoring and reading.

"There are two surveillance cameras in Folk Street, one on each side of the street. We have marked all the vehicles and pedestrians entering and leaving Folk Street yesterday, and are now preparing for investigation."

In the detection of murder cases, all the mechanisms are very perfect, and the process is also very complete.

Each group of people, how to divide the work, has a plan in advance, even if someone is on temporary leave, or cannot participate because of other cases, there are also AB posts for supplementary replacement.

After the incident, investigations and visits by the on-site survey, forensic doctors and other criminal police were all carried out together.

In fact, although the impact of this case was bad, it was not complicated from the perspective of detection.

The corpses were dumped on the street, and there were cameras on both sides of the street. Even if all the people who entered and exited the folk street were checked, the murderer could be found.

At present, it is obviously easier to find the murderer.

"Focus on checking all vehicles entering and exiting Folk Street last night, especially in the second half of the night!"

The work tasks were deployed very quickly, and the relevant vehicle information was quickly locked.

A total of 51 vehicles and more than 100 criminal policemen set off immediately.

Surveying the office now.

When the first-line criminal police attacked, Lu Chuan was not idle behind.

The dismemberment case is relatively unfriendly to the present survey.

Because all the body fragments must be photographed one by one to keep the files.

Obviously, these tasks cannot be done at the scene where the body parts were found, so they can only be done back.

Fortunately, Shen Yan also needs to examine the corpse, and the two work together, so they don't feel tired after busy work.

Click!

After taking another photo of a dead body, Lu Chuan straightened his waist, saw that two-thirds of the work had been completed, and breathed a sigh of relief.

"The height of your dissecting table is not suitable. You always bend over to work, and you are so tired."

Shen Yan was marking and inspecting the body parts: "That's because you are too tall, and the height of the dissecting table is regulated."

Lu Chuan smiled and continued to work.

After taking a piece of corpse that looked like a waist and belly, Lu Chuan was about to take a picture, but stopped suddenly.

"what happened?"

"This... trace... seems to be a little bit wrong."

Lu Chuan carefully placed the corpse on the dissecting table. Under the bright light, there was a speckled stain.

The marks are brown with regular edges, resembling a small circle.

"trace?"

Shen Yan looked at the traces. As a forensic doctor, Shen Yan's professionalism is beyond doubt: "Is it... blood?"

Human blood changes quite differently at different times and in different environments after the death of the human body.

Especially in the eyes of professionals, the size, color, and edge shape of these marks have special significance.

"Could it be that other body parts of the body rubbed against it?"

Lu Chuan pondered for a moment, then shook his head slightly: "This is dripping blood, I haven't seen it on other corpses."

The corpse was refrigerated at low temperature for a short period of time, so the blood in the corpse was coagulated, and there was no trace of blood after the murderer threw the corpse.

However, as time went by, the corpses thawed, and many corpses rubbed against each other, stained with friction-shaped blood.

But what Lu Chuan found now was dripping blood.

In bloodstain morphology analysis, dripping bloodstains can judge many static on-site indicators.
