Chapter 615 Cautious Suspect

The detective in charge of the on-site investigation was named Wang Qiang. When he saw Chen Yan coming over, he said, "Hello, Captain Chen. No valuable clues have been found yet."

"There are fingerprints on the four door handles, the driver's seat and the rear door, but there are no fingerprints on the passenger's handle. They must have been wiped off by the murderer."

"No valuable clues have been extracted from the car yet. Fingerprint traces have also been wiped out on the door handle and door lock handle inside the passenger side. There are no shoe prints or mud on the floor mats. There are traces of being wiped. There are no traces of wiping on other places. No fingerprints found."

The more he listened to Chen Yan, the deeper his frown deepened.

Judging from the on-site investigation, the murderer was obviously very cautious and erased all traces of his existence after the murder. In particular, the other party even cleaned the passenger's floor mats, which shows that the other party had a certain awareness of counter-reconnaissance.

"Did you find anything around the vehicle?"

Wang Qiang shook his head: "This is a cement road. It is difficult to leave footprints. We checked the surrounding area ourselves and found no valuable clues."

Chen Yan nodded and turned on the olfactory gene lock and visual gene lock to carefully inspect everything in the car.

Since the passenger window was half-open and the sunroof of the vehicle was not closed, the air flow in the vehicle was relatively fast and many odors had long since dissipated, but there was still a faint smell of alcohol.

Chen Yan frowned and looked at the body lying on the steering wheel. The deceased was drinking and driving?

The carotid artery of the deceased was punctured, and he died of hemorrhage and shock. It was obvious that he died of homicide, that is, there should have been other people in the car besides the deceased.

However, because the murderer stayed in the car for a very short time, he should have been introduced into the car to kill immediately and then cleaned up the scene and left the car. In addition, the car windows and sunroof were not safely closed, so Chen Yan could not detect the other party's scent mark.

However, there was still a strong smell of alcohol in the carriage, and the source of the smell turned out to be the deceased.

Opening the car, Chen Yan carefully observed the geographical location of the crime scene.

Binhe Road is a road with a low flow of people and vehicles. It is only about three kilometers long. There are main roads on both sides. Chen Yan had noticed when he came to the intersection just now that there are surveillance cameras at the intersection.

The deceased parked his car in the middle of the main road leading to Hengchang Community. It is one kilometer away from the community and one kilometer from the previous intersection.

The deceased was drinking and driving last night and was probably killed on his way back home, but there is a question here.

When did the co-pilot's murderer enter the car?

Did he get into the car with the deceased, or did he get into the car along this stretch of riverside road?

This is actually not difficult to judge. The deceased could not have been drinking alone. As long as you find the person who was eating with him, you can find out through investigation.

This would be very interesting if the other party was driving alone yesterday.

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 passenger seat in the middle of the night.

The investigation of the scene was quickly completed, and the autopsy of the body was also being performed.

In the conference 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, stood up and turned on the projector: "The deceased Wang Xu, male, 43 years old, supervisor of Tianshun Engineering Supervision Company, died between 1:30 and 2 o'clock this morning. The cause of death was hemorrhagic syndrome caused by the puncture of the cervical artery. Death from shock."

"The place where the deceased was killed is located on Binhe Road. Normally, the flow of people and vehicles on this section of the road is very small. Most of the people entering and exiting are residents of Hengchang Community, which is the community where the deceased lived. There were basically no vehicles or vehicles in the early morning when the deceased died. Pedestrians passing by.”

"The reporter's name is Sun Jun, a sanitation worker. He found the deceased while cleaning garbage on the roadside this morning and called to report the incident at 7:28."

"After the police were dispatched, we conducted a detailed investigation of the scene and found that fingerprints had been wiped off the passenger door handle of the vehicle, and there were traces of wiping on the passenger floor mat."

"Fingerprints were also wiped off the door handle and door lock handle on the passenger side."

"It can be said that the murderer did not leave any valuable clues. The fingerprints extracted in the car are being matched. There are no results yet. However, judging from the murderer's behavior in cleaning up 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 let's start arranging the investigation of the case."

"First, investigate the whereabouts of the deceased Wang Xu last night. There was a strong smell of alcohol in the Buick driven by the deceased. It is very likely that the deceased drove after drinking last night. We need to find the person who ate and drank with Wang Xu and conduct an investigation. "

"Wang Gang, you are responsible for this matter."

"yes."

"Second, Binhe Road connects the two main roads of Changjiang Road and Huanghe Road. When I just went to the scene, I noticed that there were surveillance cameras at the intersection of Changjiang Road and Binhe Road."

"Judging from the direction in which the front of the Buick was parked, 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 determine the exact time when the other party entered Binhe Road. "

"We also need to investigate the surveillance on Huanghe Road. 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 position of the knife in his neck, it can be proven that the murderer was sitting in the passenger seat at the time."

"Since the murderer was able to sit in the passenger seat of Wang Xu's vehicle, whether the murderer got into the car when Wang Xu finished the drinking party or entered the car on Binhe Road or some other road section, it can be shown that the murderer should know Wang Xu. Otherwise, he wouldn’t have been able to get into Wang Xu’s car.”

"After confirming this, we only need to check the surveillance of Changjiang Road and Binhe Road to determine where this person got on the bus."

"If it was at the end of the drinking party, then the person who drank with Wang Xu yesterday should know who the other party is."

"And if you take the bus from Binhe Road, it will be easier."

Chen Yan walked to the projector and pointed to the overhead map of Binhe Road on the projection: "Binhe Road is only 3 kilometers long. It connects Changjiang Road and Huanghe Road and there is 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."

"On both sides of this road, on the left side is the courtyard wall of Hengchang Community. This height is three meters. It is impossible for ordinary people to come out from here. On the right side is the riverside, and it is impossible for the murderer to appear from here."

"Then if the murderer enters Binhe Road, he will definitely pass by the three cameras I just mentioned."

"Check, during the 12 hours before and after yesterday's crime, was there anyone who entered one camera but did not appear in the other two cameras, or whether there were cars or pedestrians that appeared for an obviously too long time."

"Chaoyang, you are responsible for this!"

"yes!"

Everyone understood Chen Yan's thoughts. No one present was unconvinced that he could make such an accurate judgment based only on the surrounding environment and the time the deceased was killed at a crime scene with no clues.

The results of the investigation were quickly reported back.
