The greening in the Peach Blossom Villa area is very good, shaded by woods, and it looks very lively even in winter.
Lu Chuan was a detective after all.
Inspection is the first step into any site.
Subconsciously putting on his gloves, Lu Chuan carefully observed the entrance door to the courtyard.
The two townhouses each have a gate.
At this moment, the door of the villa where Chen Weiwei lives is locked, and there should be a courtyard inside.
The door lock showed no signs of prying.
"Zhao Kai, send someone to climb over from the next door, open the door, be sure to wear gloves and don't touch things you shouldn't touch."
"Yes."
The captain of the first squadron sent a nimble team member to climb over the wall of the villa next door and open the entrance door from the inside.
"Lao Gao, start from the gate and collect the fingerprints on it."
Since it has been determined that the deceased is Chen Weiwei, her residence is likely to be the scene of the first crime.
Lu Chuan asked everyone else to wait outside and only brought Wang Zhaokai in.
Both of them carefully put on their shoe covers.
"Army!"
Entering the yard, Wang Zhaokai suddenly pointed to a brown mark on the ground.
Lu Chuan looked down and saw blood stains!
Dried blood!
And judging from the blood stains, they were continuous dripping blood stains.
Part of the brown blood dripped on the stone road, and part of it dripped on the grass next to it, extending all the way to the entrance door.
"Wait a minute!"
Lu Chuan squatted directly next to the blood stains and observed carefully.
In the identification and analysis of blood stains, the height of the blood stain drop can be calculated based on the diameter of the blood stain drop and the length of the burr.
Generally speaking, the height at which the murderer's arm naturally hangs down when holding a body with low blood stains, from which the distance from the murderer's arm to the ground can be calculated.
In addition, the proportions of limbs and height of normal people are relatively fixed.
The height of the arms from the ground is directly proportional to the height.
Based on this, we can roughly determine the height range of the murderer.
Of course there are individual cases. Some people may have particularly long arms but average height.
So, it can only be a rough estimate.
It cannot be said to be absolutely possible.
"Zhao Kai, bring the spot camera and take pictures of these blood stains."
"Yes."
The Criminal Police Brigade is different from the Criminal Investigation Detachment. There is no specialized scene investigation criminal police.
Gao Wenxiang is only a fingerprint identification and analysis person, and his field investigation is actually average.
So when we arrive at the scene, the investigation work is actually done by the people from the criminal police squadron.
In fact, the organizational structure of the Criminal Police Brigade has been improving over the years.
What technical team, or current survey team, etc.?
But an institution is an institution, and a setting is a setting. The key lies in whether there are people.
The three squadrons under the High-tech Zone Criminal Police Brigade are busy handling cases in the field, let alone setting up a technical team with people.
Young people want to do things with a sense of accomplishment, but older people are not capable.
The criminal policemen in the middle age group are the backbone of the business. If they are drawn out to form a technical team, it will have a great impact on external case handling.
So, many reforms have been implemented at the lower level and are really difficult to implement.
The idea is perfect, but the reality is very skinny.
In the final analysis, there are too many cases and too few people.
Entering the courtyard, Lu Chuan moved forward cautiously, observing the blood stains on the ground and looking carefully for any footprints.
"Here, circle it with chalk."
There is a distance of about ten meters from the gate to the entrance door in the yard.
Lu Chuan has found about four or five footprints.
Wang Zhaokai hasn’t done anything at a crime scene for a long time, but his movements are familiar. Whatever Lu Chuan asked him to do, he completed it immediately.
Approaching the entrance door, Lu Chuan pushed it gently. The door was ajar and unlocked.
And on the door, there was a vague bloody handprint.
There are various signs that this is indeed the scene of the first crime. Lu Chuan used the spot camera in his hand to take pictures of the bloody fingerprints, preparing to go back for comparison and analysis.
After entering the room, the first sight is very messy.
The entire first floor seemed to have been robbed. All the drawers had been opened and the contents were scattered everywhere.
"Robbery and murder?"
Wang Wang Zhaokai followed Lu Chuan into the room. Seeing the scene in front of him, he couldn't help but think of this word.
Lu Chuan shook his head.
“It shouldn’t be as simple as robbery and murder.”
“If it is robbery and murder, the murderer only needs to kill the person and take away the things. There is no need to go to so much trouble. The deceased was cut into pieces and then thrown away.”
When it comes to robbery and killing, the key point lies in the robbery ahead.
The purpose is to rob money and kill people, and the second is to prevent themselves from being exposed.
But the murderer's main goal is robbery.
The murderer in this case does not seem to just kill for robbery.
Because he disposed of the body too finely, which would cost the other party a lot of time.
If it is just for robbery, this behavior is obviously illogical.
Killing is the first goal.
Looking for money may be just a matter of convenience, or may be an attempt to create the appearance of a robbery.
The vast majority of criminal suspects are not proficient in psychology.
So he doesn’t know the difference between real robbery and murder and fake robbery and murder.
In addition, when Lu Chuan came in just now, he found that the admission door had no signs of prying, and the lock of the entrance door was intact, with no signs of being forced open.
So if the murderer committed robbery and murder, how did he enter the room?
Climb through the window?
The Taohua Villa area is of high quality, and alarm devices are installed in the windows of each household.
If someone enters without permission, the property management will be the first to find out.
In addition, the management in the community is very strict.
When Lu Chuan was at the gate of the community just now, he saw that even the delivery couriers could not enter the community.
Things can only be left at the gate of the community, and then the property management personnel will deliver the things to the owner's home.
Therefore, this community is basically cut off from the possibility of outside strangers entering.
So if it was theft and robbery, it was impossible for outsiders to do it. Could it be someone from the property management of the community who did it?
In comparison, Lu Chuan believed that it was the person brought in by the owner.
Only the owner’s vehicle at the gate of the community does not need to be inspected.
Of course, people in the car do not need to register.
Other outside visitors who enter must register their information.
You can only enter the community by contacting the owner through his phone number.
"Lijun, here!"
Wang Zhaokai's voice came from the kitchen, and Lu Chuan went over to take a look...
Dazzling dark red, spraying everywhere.
There is a sharp boning knife on the chopping board, which is covered with blood.
There is a bone cutter on the ground, and the splattered blood has dried and turned dark red.
There was still a pungent smell of blood throughout the kitchen.
This should be the scene of the first murder and dismemberment of the murderer.
Looking around, Lu Chuan noticed the refrigerator next to the kitchen door, which had obvious bloody fingerprints on it.
Frowning, Lu Chuan opened the refrigerator door of the cold room.
Wang Zhaokai, who was next to him, subconsciously took half a step back.
"This..."
The victim's head was finally found.
“Immediately send someone to seal off the scene, and I will conduct an on-site inspection myself!”
Lu Chuan immediately issued the order. (End of this chapter)
