Chapter 620 Construction Site

When Chen Yan squatted down, Liu Qingshan also noticed it and walked quickly to Chen Yan's side.

"What happened? Did you find anything?"

Liu Qingshan squatted down and followed Chen Yan's gaze to the reflective debris in the grass on the roadside.

Chen Yan shook his head: "These should be fragments of wine bottles, right?"

Liu Qingshan nodded: "Someone probably broke the wine bottle on the road, and it was swept to both sides of the road. What happened? Is there something wrong with this thing?"

Chen Yan frowned, put on the gloves he carried with him, picked up a piece of debris and looked at it carefully: "I can't say there is anything wrong with it."

"Look at the fractures of these wine bottle fragments. The surface is very clean. I remember it just rained lightly the day before yesterday, right?"

Liu Qingshan nodded: "It rained the morning before yesterday and stopped in the afternoon."

Chen Yan nodded: "It rained in the morning the day before yesterday and stopped in the afternoon, but there are no traces of raindrops on these wine bottle fragments."

"The fracture is also very clean, which means that the fragments of these wine bottles should have appeared on the riverside road after the rain stopped the day before yesterday."

Liu Qingshan nodded: "Judging from the freshness and cleanliness of the wine bottle fragments, it should indeed have appeared after the rain stopped, and it only appeared after the road surface dried in the afternoon, otherwise it would have been stained with mud."

Chen Yan nodded: "In this way, we will arrange for the cleaning staff who reported the crime to be summoned to the team and ask him when he found these wine bottle fragments."

"The other party cleans this section of Binhe Road every morning. Ask him if he saw these glass and wine bottle fragments yesterday morning, or if these fragments only appeared this morning."

"Okay, I'll make arrangements right now."

After saying that, the two stood up and left, but before taking a few steps, Chen Yan suddenly turned around and looked at the bottle fragments thoughtfully. He did not leave for a while, and Liu Qingshan did not urge him. Chen Yan with this expression was obviously thinking about clues.

Sure enough, Chen Yan took out his mobile phone after a while: "Chaoyang, send reconnaissance investigators to Binhe Road. I found something and asked them to take it back for technical appraisal."

Technical appraisal?

Liu Qingshan looked at Chen Yan with some confusion: "Do you suspect that these bottle fragments are related to Wang Xu's murder?"

Chen Yan nodded heavily: "It's not just that they are related. I even suspect that these wine bottles were broken by the murderer. If the other party is a little careless, it is very likely that his fingerprints will be left on these wine bottles, but that is not the case." Definitely, let’s check it out first.”

Soon, on-site detectives took over the scene and began taking photos to determine the location of the fragments and collect them all.

Chen Yan and Liu Qingshan walked along Binhe Road to Hengchang Community not far away.

Wang Xu lives in Unit 1003, Building 3, and detectives have visited Wang Xu's wife many times to inquire.

The building where Wang Xu lives has surveillance cameras in the elevator, as well as at the unit door and the unit entrance to the underground garage.

The detective team has reviewed the video recordings from three cameras and can confirm that Zhang Huihui was in the room and never left the unit on the night of the crime. Zhang Huihui had no time to commit the crime.

Moreover, according to the results of interviews with relevant neighbors, it was concluded that the relationship between Zhang Huihui and Wang Xu was relatively stable, and there had never been any quarrels or domestic violence.

Chen Yan came to Hengchang Community this time not to find Zhang Huihui, but to Qin Yu's decoration site.

Judging from the clues currently available, Qin Yu is the only person who has a conflict with Wang Xu. It can be said that Qin Yu's father died indirectly because of Wang Xu. From a certain point of view, Qin Yu believes that Wang Xu is his father-in-law. Enemy.

Therefore, in terms of motive for committing the crime, Qin Yu is the most suspect among all the related persons currently known to Chen Yan and others.

And the most important thing is that Qin Yu said that he was sleeping at the decoration construction site on the night of the incident, but there was no other witness.

The most important thing is that Qin Yu's emotions during the interrogation were very inconsistent with his true heartbeat rate.

Room 202, Unit 2, Building 1.

This is the room Qin Yuqian decorated, and it is also the room he said he lived in on the night of the crime.

Qin Yu's construction team has renovated two houses in Hengchang Community. This is one of them and the other one is in Room 803, Unit 1, Building 3, which is downstairs of Wang Xu's house.

Chen Yan first went to room 202. The decoration of the house was nearing completion. There was a simple wooden board in the living room that could barely be called a bed, and a quilt in the corner.

Liu Qingshan put on his gloves, turned over the quilt, and began to check carefully.

Chen Yan looked around randomly in several rooms in the house, and after a few minutes, returned to the living room again.

"Did you find anything?"

"I found some hair on the quilt. The quilt must have been used by someone, but we still need to take it back for testing to see if it is Qin Yu."

Chen Yan nodded: "According to Qin Yu's explanation, the decoration of this house is coming to an end. He is only doing some finishing work here, but I just took a look and there is basically nothing left to do in the decoration of the room."

"Even the master bedroom and the second bedroom seem to have been cleaned. Qin Yu lives here..."

Chen Yan shook his head and called Liu Qingshan to the kitchen: "Look at these."

Liu Qingshan took a closer look: "Wine bottle?"

"What do you mean, are those wine bottle fragments on the road just now made by Qin Yu?"

Chen Yan nodded first, then shook his head: "It might be Qin Yu, but it might not be. Take these bottles back and test the composition of the bottle fragments to see if they are the same kind of bottles."

"But if there are no fingerprints on the bottle fragments, it cannot be confirmed that Qin Yu did it. After all, this kind of beer bottles are everywhere, and the glass composition is no different."

"I just have a guess. If it is true, it will be of great help in solving the case."

"Then what is Qin Yu's purpose of living here?"

Liu Qingshan still doesn't quite understand that Qin Yu lives here just to meet the construction deadline?

According to Qin Yu's explanation, the decoration of his house in Building 3 was in a hurry, so Qin Yu had been living in the community during this period without going home. The decoration of the house was in a half-finished state and there was no way for people to live in it, so he Live in Building 1, Room 202.

But is this really the real reason he lives here?

Who hasn’t renovated their house yet?

Can the construction deadline be solved by sleeping on site? There are time points for house decoration in residential areas. Noisy construction cannot be carried out after 8 pm, otherwise neighbors will definitely complain.

Besides, Qin Yu is the only one living at the construction site. What does it mean to advance the construction progress if other workers are not here?

This is the most important reason why Chen Yan went to Hengchang Community to take a look at the construction site!

Sure enough, a problem was discovered.
