Chapter 619 New Discovery
After leaving the interrogation room, Liu Qingshan looked at Chen Yan with a deep expression and asked, "Is this Qin Yu... telling the truth?"
The truth?
Chen Yan was actually not sure. During the interrogation process, Qin Yu's expression and look were very calm. There were no small movements on his hands and he did not show any special nervousness or fear.
Qin Yu's behavior cannot be said to be abnormal, but it cannot be said to be normal either.
No matter whether people have done bad things or not, they would be nervous or scared when they join the detective team.
Although Qin Yu was a little nervous, he was somewhat deliberate, as if he had known for a long time that he was going to join the detective team.
In the second half of the interrogation, Qin Yu was extremely excited!
Qin Yu showed extreme surprise and shock at Wang Xu's murder, as well as his expectation for Wang Xu's death.
Throughout the whole process, Qin Yu's expression, laughter, and body movements were very coordinated.
However, don't forget that Chen Yan has the ability to open the hearing gene lock.
Logically speaking, if Qin Yu was so excited about Wang Xu's death, his heartbeat would definitely speed up and his blood circulation would speed up.
However, Chen Yan did not hear any change in Qin Yu's heartbeat. During the entire interrogation process, Qin Yu's heartbeat was very gentle and maintained at a relatively stable frequency.
Expressions can be deceiving, but heartbeat frequency cannot, which means that when faced with the news of Wang Xu's death, Qin Yu was actually not as excited as he appeared. .
So, why does he want to act?
There are only two reasons. First, Wang Xu's death was related to Qin Yu, and he was the one who killed him.
The second possibility is that Qin Yu actually knew about Wang Xu's death and just pretended not to know during the interrogation.
Which one it is still needs to be investigated.
"It is still uncertain whether Qin Yu is the murderer of Wang Xu, but during the interrogation just now, Qin Yu must have lied."
"Because during the whole process, Qin Yu's heartbeat rate was very stable. After hearing the news of Wang Xun's death, his expression and voice were very excited, but there was still no major change in his heartbeat rate."
"So, either the other party is the murderer, or he has known about Wang Xu's death for a long time. Whichever it is, further investigation is needed."
"In this case, let's go to Hengchang Community and have a look."
"good."
In fact, another important reason why it has not been determined whether Qin Yu is the murderer is that Wang Xu's murder has been determined to be committed by an acquaintance.
Qin Yu and Wang Xu could not be considered acquaintances in any way. Is it possible for Wang Xu to let Qin Yu get in the car in the middle of the night?
Judging from the fact that Wang Xu left the drinking table and was able to drive home by himself, although Wang Xu drank, he did not drink to the extent that Lingding was drunk. It is also impossible not to know Qin Yu, the son of a contractor who died because of drinking with him. .
Chen Yan had read the case files in detail when interrogating Qin Yu. In order to get an explanation for his father, Qin Yu had visited Wang Xu many times and even had several physical conflicts. Therefore, it was impossible for Wang Xu not to know Qin Yu. rain.
That is to say, if Qin Yu is really the murderer, then this reasoning is contrary to the early judgments of Chen Yan and others.
Twenty minutes later, Chen Yan arrived at the crime scene again, but unlike last time, Chen Yan did not take a bus into Binhe Road, but got off the bus at the intersection of Changjiang Road and Binhe Road.
"Why do you get off the bus here?"
Liu Qingshan got off the car after Chen Yan, a little confused. It was still more than two kilometers away from Hengchang Community.
Chen Yan looked at the surveillance camera above his head: "Wang Xu's vehicle turned into Binhe Road from this intersection early yesterday morning. The other party parked on Binhe Road. The murderer also drove on Binhe Road. We believe that an acquaintance committed the crime."
Liu Qingshan nodded: "Yes, Wang Xu let the murderer get in the car halfway, which means that the other party and the murderer must be familiar with each other."
"It's not just halfway. Wang Xu was only 1 kilometer away from the Hengchang community where he lived, which means he was home in about two minutes' drive. What was the situation when he asked others to get in the car at this time?"
"This is also one of my doubts. Could the murderer be Wang Xu's friend who also lives in Hengchang Community?"
Chen Yan shook his head: "This may exist, but our investigation of Wang Xu's close interpersonal relationships shows that no such person exists."
"More importantly, we did not find anyone around Wang Xu who had a major conflict of interest with him that would lead to the murder."
"The only person who has a grudge against him is Qin Yu."
"However, what Qin Yu just said during the interrogation reminded me."
"Huh? What are you talking about?"
"Qin Yu said that when Wang Xu was working as a project supervisor, he often asked the contractor for cigarettes, alcohol, and money. Therefore, from this point of view, it can be seen that Wang Xu is a person who loves petty gains."
The two of them were chatting while walking forward, and Chen Yan was also carefully observing the surrounding road: "When we were surveying the scene yesterday, we found 4 bottles of wine and 5 cigarettes in the trunk of Wang Xu's vehicle. This also proves that Qin What Yu said must be true.”
"So, if we make a bold assumption that someone whom Wang Xu is not very familiar with, or even doesn't know, gave Wang Xu a gift in the early hours of yesterday morning...will Wang Xu let the other person get in the car?"
Um?
Liu Qingshan was slightly startled. Chen Yan's inference was indeed possible.
"But the question is, if the other party doesn't know Wang Xu or is not particularly familiar with Wang Xu, how did he stop Wang Xu's car?"
The prerequisite for Wang Xu to allow the other party to get in the car is that Wang Xu stops the car.
But in the middle of the night yesterday morning, Wang Xu was driving home drunk, and a man suddenly appeared on the pedestrian-free Binhe Road and stopped the car. How would a normal person react?
Most people will definitely increase the accelerator and leave quickly instead of stopping.
So how did the other party ask Wang Xu to stop the car? You can't just wave to stop with a wad of cash in your hand, right?
Chen Yan smiled and said, "This is what I was confused about, so I got off the bus at the intersection of Changjiang Road and walked a section of this Binhe Road myself!"
Although Binhe Road has a small flow of people and vehicles, the road surface is paved with cement and is relatively clean and tidy. Cleaners clean it every day.
Chen Yan walked along the roadside while chatting with Liu Qingshan and searching the surroundings.
"We still have a few hundred meters to go to the crime scene."
The vehicles at the crime scene have been towed away, and the entire road has returned to its usual appearance.
Chen Yan nodded and looked up in the direction of Liu Qingshan's finger. It was indeed not far away from where Wang Xu was found murdered.
Um?
However, just when he raised his head, Chen Yan saw a reflection in the corner of his eyes.
Stepping forward quickly, Chen Yan knelt down and looked at the reflective objects on the roadside, frowning deeply.
Is that what happened?
