Chapter 614: A Cautious Suspect
The detective in charge of the on-site investigation was called Wang Qiang, and when he saw Chen Yan coming over, he said, Hello, Team Chen, I haven't found any valuable clues yet.
There are fingerprints on the four door handles, the driver's seat and the rear door, but there are no fingerprints on the handle of the co-pilot, which should have been wiped off by the murderer.
No valuable clues have been extracted in the compartment for the time being. The fingerprint traces on the door handle and door lock handle inside the co-pilot have also been wiped out. There are no shoe prints or mud on the floor mats. There are traces of being wiped, and there are no other places. Find any fingerprints.
The more Chen Yan listened, the deeper his frown became.
Judging from the on-site investigation, the murderer was obviously very cautious and erased all traces of his existence after the murder, especially the other party even cleaned the floor mat of the co-pilot, which shows that the other party has a certain anti-reconnaissance awareness.
Have you found anything around the vehicle?
Wang Qiang shook his head: This is a concrete road, and it is difficult to leave footprints. We checked the surrounding area ourselves and found no valuable clues.
Chen Yan nodded, turned on the olfactory gene lock and visual gene lock to carefully inspect everything in the car.
Since the co-pilot's window was half open and the sunroof of the vehicle was not closed, the air flow in the vehicle was relatively fast, and a lot of the smell had dissipated long ago, but there was still a faint smell of alcohol.
Chen Yan frowned and looked at the corpse lying on the steering wheel. The deceased was drinking and driving?
The deceased's carotid artery was punctured, and he died of hemorrhagic shock. Obviously, he died of homicide, that is, other people should have entered the car besides the deceased.
It's just that because the murderer stayed in the car for a very short time, he should have led the car into the car and killed him immediately, then cleaned up the scene and left the car, and the windows and sunroof were not closed safely, Chen Yan did not extract the scent mark of the other party.
but,
There was still a relatively strong smell of alcohol in the compartment, and the source of the smell turned out to be the deceased.
Opening the carriage, Chen Yan carefully observed the geographical location of the crime scene.
Binhe Road, this is a section of road with not too much flow of people and traffic. It is only about three kilometers long, with main roads on both sides. Chen Yan had already noticed when he came over at the intersection that there are surveillance cameras at the intersection.
The location where the deceased parked was in the middle of the main road on one side leading to Hengchang Community, which was one kilometer away from the community and one kilometer from the previous intersection.
The deceased was drinking and driving last night. He should have been killed on the way back home, but there is a question here.
When did the murderer in the co-pilot get into the car?
Did he get into the car with the deceased, or did he get into the car on this section of the riverside road?
This point is actually not difficult to judge. It is impossible for the deceased to drink alone. As long as you find the person who had dinner with him, you can find out after investigating.
If the other party was driving alone yesterday, it would be very interesting.
How did the murderer get into the car?
There is a high probability that an acquaintance committed the crime, otherwise, the deceased would not have allowed a stranger to enter his co-pilot in the middle of the night.
The investigation work on the scene ended soon, and the corpse was also being autopsied.
In the meeting room of the second team, Chen Yan organized the first case analysis meeting.
Chaoyang, please give a brief introduction to the case.
Zhang Chaoyang nodded, got up and turned on the projector: The deceased Wang Xu, male, 43 years old, a supervisor of Tianshun Engineering Supervision Company, died between 1:30 and 2:00 this morning. The cause of death was blood loss caused by a punctured carotid artery. Death from shock.
The place where the deceased was murdered was located on Binhe Road. On this section of the road, the flow of people and vehicles is usually very small. Most of the people entering and leaving are Hengchang Community, that is, the residents of the deceased's residential area. In the early morning when the deceased died, there were basically no vehicles or vehicles. Pedestrians pass by.
The person who reported the case was Sun Jun, a sanitation worker. He found the deceased while cleaning up rubbish on the side of the road this morning, and called to report the case at 7:28.
After the police were dispatched, we conducted a detailed survey of the scene and found that the fingerprints on the door handle of the co-pilot of the vehicle had been wiped off, and there were traces of wiping on the floor mat of the co-pilot.
Fingerprints on the door handle and door lock handle on the inside of the passenger side were also wiped off.
It can be said that the murderer did not leave any valuable clues. The fingerprints extracted in the car are being matched, and there is no result yet. However, judging from the murderer's behavior at the scene, it is unlikely that we will find the other party's fingerprints.
Team Chen, the basic situation is like this.
Chen Yan nodded: Now we will start the investigation of the case.
First, investigate the whereabouts of the deceased Wang Xu last night. The Buick the deceased was driving had a relatively strong smell of alcohol. It is very likely that the deceased drove after drinking last night. Find the person who ate and drank with Wang Xu and conduct an investigation.
Wang Gang, you are responsible for this matter.
yes.
Secondly, Binhe Road connects the two main roads, Changjiang Road and Huanghe Road. When I went to the scene, I noticed that there are surveillance cameras at the intersection of Changjiang Road and Binhe Road.
Judging from the direction in which the Buick stopped, Wang Xu should have entered Binhe Road from Changjiang Road. Check the surveillance to see if Wang Xu was driving alone at the time, and at the same time determine the exact time when the other party entered Binhe Road.
The monitoring on the Yellow River Road side also needs to be investigated. Although the murderer did not leave any clues in the car, Wang Xu himself died in the driver's seat of the car, which provided us with more information.
First, it is basically certain that an acquaintance committed the crime, because judging from Wang Xu's death posture and the location of the knife in his neck, it can be proved that the murderer was sitting in the co-pilot at that time.
Since the murderer was able to sit in the co-pilot of Wang Xu's vehicle, no matter whether the murderer got into the car when Wang Xu finished drinking or entered the car on Binhe Road or other road sections, it can show that the other party should know Wang Xu. Xu otherwise, he wouldn't be able to get into Wang Xu's car.
After confirming this point, we only need to check the surveillance cameras on Changjiang Road and Binhe Road to determine where this person got into the car.
If it was at the end of the drinking session, then the person who drank with Wang Xu yesterday should know who the other party is.
And if you drive from the Riverside Road, it will be easier.
Chen Yan walked to the projector and pointed to the projected overhead map of Binhe Road: The length of Binhe Road is only 3 kilometers, connecting Changjiang Road and Huanghe Road, and there is a Hengchang Community in the middle.
There are only three cameras on this road, one is at the intersection of Binhe Road and Changjiang Road, one is at the intersection of Binhe Road and Huanghe Road, and the other is at the gate of Hengchang Community.
And on both sides of this road, on the left is the courtyard wall of the Hengchang Community. This height is three meters. It is impossible for ordinary people to come out from here. On the right is Binhe, and it is impossible for the murderer to appear from here.
Then if the murderer enters Binhe Road, he will definitely pass the three cameras I just mentioned.
Check, did anyone enter one camera in the 12 hours before and after yesterday's incident but did not appear in the other two cameras, or was there a car or pedestrian that appeared for too long.
Chaoyang, you are responsible for this matter!
yes!
Everyone understood Chen Yan's thoughts. At a crime scene with no clues, he was able to make such an accurate judgment based on the surrounding environment and the time when the deceased was killed. No one present was not convinced.
The results of the investigation were soon reported back.
