Two hours later.
Qin Yong took a large number of people to Wuhua Mountain.
The people who followed the police out now looked at Lu Chuan and Shen Yan very strangely.
Zhang Hui clicked his tongue twice and poked Lu Chuan in the waist: "Brothers, you two...you have such a reputation that you really can't live up to."
They all say that only giving wrong names can There's no mistaking the nickname, and the Death Duo certainly deserves their reputation.
It had only been a few days since the last time the two of them went to the Donghai camping area and discovered the mummy case inside the stone statue.
During this period, the criminal investigation detachment finally calmed down. There were no major cases, but here comes one.
Lu Chuan spread his hands and sighed silently.
Shen Yan on the other side had a flat mouth and a little helplessness on her face.
Didn’t the two of them just come out to have some fun? Who would have thought that they would run into another case.
"Brother Hui, we didn't want to either. We had no choice but to run into it. What do you think we should do?"
Ahem.
Qin Yong coughed twice, interrupting their conversation.
“Okay, let’s handle the case first.”
“Lu Chuan, what’s going on at the scene?”
When the case was mentioned, everyone's expressions became serious. Lu Chuan straightened his expression and reported to Qin Yong.
“At around 9:30 this morning, Shen Yan and I were playing in Wuhua Mountain.”
“Two corners ahead, I heard someone shouting for help. Shen Yan and I ran over."
The two young men who saw the corpse during the field battle are still trembling.
"Two young men were the first to discover the body."
"Subsequently, I entered the scene for the second time and found a female body hanging on a tree branch in the woods below, with her neck suspended by shoelaces. The body was in a highly decomposed state."
"I have already learned about it. A preliminary investigation was conducted at the scene. The deceased was a female who was about 30 years old and 1.58 meters tall. "
"The time of death was initially determined to be about two weeks, and the cause of death is temporarily undetermined."
< br>When Lu Chuan was doing preliminary on-site investigation, he did not conduct a contact inspection on the body because he did not bring tools or gloves.
Qin Yong nodded and then asked: "How is the surrounding situation?"
Lu Chuan knew that what Qin Yong meant was that if it was a murder, did the murderer leave any evidence around him?
“Autumn has just begun recently, and the leaves have all fallen. There are no obvious traces around, but it is likely to be covered by fallen leaves. Further investigation is needed to find clues.”
As for Whether the other party committed suicide or was a homicide, Lu Chuan had a judgment when he called Qin Yong to report. It could basically be determined that it was a homicide.
Because if the other party hanged himself to death, then the other party must have a place to stand on when hanging himself.
It is also possible to climb a tree alive or hang yourself from a branch.
However, there were no signs of climbing on the trees at the site, and there were no stones or other things to step on on the ground.
After listening to the report, Qin Yong asked the action team to take notes on the two young men who first discovered the body.
“The current investigation will be carried out first, and then the forensic autopsy will be conducted.”
Because it is an unexpected case and today is the weekend, not all people are here. At the current investigation office, Lu Chuan is here At the scene, Yang Sen went out, and Lao Bai and Liu Guodong came over.
“Master, let’s take the corpse as the center and clean up the fallen leaves around to see if we can find some clues.”
Liu Guodong nodded. This place was outdoors and inaccessible. If the murderer left any clues, they would most likely not be damaged.
Since it has just entered autumn, all the fallen leaves on the trees have not fallen yet. There is only a thin layer of fresh fallen leaves on the ground. After these fallen leaves are removed, underneath are the rotten fallen leaves left behind from last year.
The three people centered on the corpse and radiated around, and soon discovered some clues.
Whether it was Lu Chuan or the two young men who first discovered the body, the footprints left behind were all on the newly fallen leaves.
Such footprints are trampled underneath by fresh fallen leaves, while the marks on rotten leaves are relatively shallow.
But if you step on rotten leaves before they fall, the marks will be deeper.
“Lu Chuan, look here!”
Lao Bai soon made a discovery.
After cleaning the fresh fallen leaves under the corpse, Lao Bai discovered some inconspicuous holes in the rotten leaves.
I probed with my finger and found that there was some depth, about three or four centimeters.
“It was the heel of the high-heeled shoes that stepped in.”
Lu Chuan just glanced at it and knew what kind of footprints it was.
Squat down, take out the ruler, and measure the footprints.
"The hollow part of the high heel and the hollow part of the forefoot...are 5.6 centimeters. The high heels the other party wears are size 40. The depth of the holes is...three to four centimeters..."
"The murderer is most likely a female, with a height of between 1.79 and 1.8 meters, and an age of about 25 to 30 years old..."
Lu Chuan measured and dictated what he found. clue.
The footprints left by the murderer on decaying leaves are different from the footprints left on ordinary hard ground.
When Lu Chuan was doing analysis, the calculations were relatively slow and very difficult.
But fortunately, the footprints left by high heels were quite special, which allowed Lu Chuan to get some clues.
In addition, the three of them followed the footprints of holes left by high heels, peeled away the fallen leaves covering them, and found the path where the murderer moved the body.
“The murderer carried the body down from the walking path above.”
Lu Chuan lay on the ground, observing the newly discovered line of footprints.
“There are two lines of footprints. The one here is deeper, indicating that the murderer walked forward with a heavy load. The one next to it is shallower, which should be the path she took when she returned.”
Although the holes in the high heels are pierced into the rotten leaves, the marks left by the forefoot have different depths under different gravity.
This made it easier for Lu Chuan to detect traces of the other party's coming and going.
With this clue, what Lu Chuan and others have to do next is to find other traces left by the other party on their route.
Such as fingerprints, dander or hair.
In modern criminal investigation technology, the main method of locking the identity of a suspect is to determine whether the suspect has appeared at the scene through the trace method.
Fingerprint identification analysis, footprint identification analysis, and DNA information comparison are the most commonly used methods.
Comparatively speaking, fingerprints are relatively easy to hide. As long as the other party wears gloves, fingerprints will generally not be left at the crime scene.
Footprints are actually difficult to eliminate, and even if they are eliminated, they will leave some other clues.
Of course, the identification and analysis of footprints is relatively difficult, and the success rate of identifying the suspect is not high.
And after some on-site footprints are destroyed, there is no way to extract them.
Another most commonly used trace proportion method is DNA information identification.
Because of the metabolism of the human body, everyone actually leaves his or her DNA information wherever he passes at any time.
This is an objective law and cannot be avoided by being cautious. (End of this chapter)
