Chapter 617 Background Investigation
The conference room was engulfed in discussion.
"It is impossible for the other party to swim from Binhe. The water depth of Binhe is about two meters. If the other party swam over, he would definitely leave traces on the shore. However, we conducted a blanket search nearby and found no one ashore on the shore. trace."
"Also, if the other party really swam over, then his clothes must have been wet. Could it be that this person changed his wet clothes and put on a set of dry clothes, and then got into the deceased's car and committed the murder? "
"I think the possibility is too small."
Zhao Bing believed that it was unlikely that the murderer swam from the river.
"What about the high wall on the left side of Binhe Road? Is it possible that the other party climbed over the wall?"
"this……"
"I think this may be possible. Although the wall is relatively high, about three meters high, it is normally impossible for people to climb over it, but there is definitely no problem with the help of some tools."
"But there is one thing. When I was at the site, I found that there were clumps of weeds under the wall. When we checked nearby, we found no trace of the weeds being trampled."
"And if the other party climbed the wall using tools such as ropes, there will definitely be some traces left on the wall. We only need to send people to check to determine whether the other party jumped over the wall."
The suggestion given by Wang Gang is to check for traces of circumvention.
After a while, everyone finished speaking and basically formed two suggestions.
The first is to search along the riverside. Since the riverbed is lower than the road surface, if the opponent crawls along the riverbed, it is possible to avoid the camera.
The second is to check the high wall. It is very likely that the murderer did not jump over the wall at the crime scene. There is a distance of 3 kilometers between the Hengchang community camera and the Changjiang Road intersection camera. Within this distance, the murderer It is possible to climb over the wall at any section.
Wang Gang and Zhang Chaoyang still led the team to search. As for the affairs of the second team, Chen Yan was familiar with everyone, so Zhang Chaoyang naturally did not need to cooperate here.
7:23 p.m.
Zhang Chaoyang, Wang Gang and others have not yet returned from the scene, and the autopsy report has been delivered to Chen Yan.
First of all, the cause of death of the deceased was indeed a puncture of the carotid artery leading to massive bleeding and shock death. Based on the shape of the wound, it was determined that the murder weapon was a double-edged dagger.
Second, the deceased had a high alcohol content in his body when he was killed and was drunk.
Third, there were no signs of a violent struggle before the deceased was killed, as evidenced by the direction of the blood splatter in the carriage.
In addition, ether residue was detected in the respiratory tract of the deceased. It can be determined that the deceased was stunned by the murderer with ether before death, and then punctured the carotid artery, resulting in the death of the deceased. This is also the reason why the deceased did not resist violently when he was killed.
The autopsy report provided very limited information, and the murderer left no valuable clues that could be traced on the body of the deceased.
In the office, Chen Yan was thinking about the entire crime scene alone.
According to the surveillance video at the intersection of Changjiang Road and Binhe Road, it can be determined that there was no one in the car before Wang Xu drove into Binhe Road. The murderer got into the car in the middle of Binhe Road and then committed the murder.
In this case, the focus of the question is why the murderer stopped the car and why he was allowed to get in the car.
Looking at it now, there is only one reason, and that is that the murderer and the deceased knew each other.
Chen Yan has thought about this many times, and it can be said that this is a very important investigation direction.
Therefore, when no trace of the murderer was found at the scene, the next step was to investigate the background of the deceased Wang Xu.
Since the murderer knew Wang Xu, there must be a deep-seated reason for killing Wang Xu, and it was not for money.
Killing is not for money. It is either a love killing or a vendetta. There is basically no other possibility.
Picking up the phone, Chen Yan dialed Liu Qingshan's number.
"Now it is basically confirmed that the murderer and Wang Xu are acquaintances, so you should take over the subsequent investigation of Wang Xu."
"Okay, no problem. I have arranged for people to follow up on these tasks after the incident. The results are expected to be available tomorrow."
The busy work lasted all night and the next morning.
Wang Gang and Zhang Chaoyang's investigation has produced results.
But unfortunately, the investigation results of the two men were very different from their expectations.
“The first is the investigation of the high wall on the left side of Binhe Road. We conducted a detailed survey of the entire wall, and also conducted a detailed inspection of the grass on both sides of the wall inside and outside the wall, but no climbing or trampling was found. trace."
"That is to say, there is no evidence to support that the murderer entered Binhe Road by climbing over a high wall and avoiding surveillance."
"It's the same here. Fishing is prohibited along the entire glacier, and the slope of the embankment is relatively steep. We conducted detailed searches and inspections on both sides of the river, and found no trace of anyone entering or entering the water, nor any signs of anyone entering or entering the water. There are signs of someone hiding and crawling.”
"There is basically no possibility that the murderer could avoid the cameras and enter Binhe Road from the direction of Binhe."
No, not in either direction. This is strange. Could it be that the other party flew over from the sky?
"In this way, Wang Gang, please work harder and conduct a careful inspection on both sides of the road along Binhe Road, especially the section from Hengchang Community to the intersection of Changjiang Road."
"The place where the deceased was killed is 1 kilometer away from Hengchang Community, but the place where the murderer got into the car is most likely not at the crime scene. It should be some distance in front of the crime scene."
"The other party's killing of Wang Xu was definitely not a sudden move. Judging from the traces at the scene, the other party must have planned it in advance, so the other party was most likely waiting for Wang Xu to come back on Binhe Road."
"Let's investigate the four people who drank with Wang Xu. Does anyone know what they drank yesterday? The murderer could wait for Wang Xu at such a late hour. He should know that the other party has a drinking bureau, and kill a drunk person. Far easier than killing a conscious person."
"Yes, I'll go investigate right away."
On the other hand, Liu Qingshan’s investigation also produced some results.
"We focused our investigation on Wang Xu's family situation and work situation."
"Wang Xu's wife, Zhang Huihui, does not have a fixed occupation, and they have a good relationship. According to Zhang Huihui's report, Wang Xu's life is relatively regular. Because of work, although there are many wine shops, he will tell her every time he eats, the day before yesterday Wang Xu also called Zhang Huihui before dinner. "
"It is precisely because Wang Xu called Zhang Huihui in advance that Wang Xu came back late after drinking at night, and this is why Zhang Huihui did not call the police after he was killed."
"Zhang Huihui waited until after 12 o'clock the night before yesterday. When Wang Xu had not come back, she sent Wang Xu a WeChat message. The other party replied that he would be home around 1 o'clock, so Zhang Huihui went to bed first."
"It was already past 8 o'clock when I woke up in the morning, and I was woken up by the detective's call."
"We also checked the WeChat chat records of the two on the night of the incident. Zhang Huihui did not lie."
"After that, we investigated the engineering supervision company where Wang Xu worked and found some valuable clues."
"Wang Xu joined the engineering supervision company ten years ago and has been working as a supervisor. He usually has a very harmonious relationship with his colleagues. However, three years ago, someone died due to a project supervised by Wang Xu!"
