Baohua Police Station.
Because they could not determine if the victim was an accident or a homicide, the suspects were brought back to Baohua Police Station.
In the conference room, Han Bin held a case summary meeting.
Han Bin sat in the middle of the table. On his left were the police officers from Baohua Police Station, and on his right were the police officers from Yuhua Branch.
Small Eye and Big Fool walked into the conference room and said to Han Bin, "Captain Han, Zhang Haiqiao and Dong Wenhuan are being held in custody."
"Sit down. Let's start the meeting." Han Bin glanced at everyone. "Everyone understands the case, so I won't repeat it here. Let's talk about the progress of the investigation."
"The deceased, Liu Xiaolin, was a live streamer. This so-called quarrel and suicide was actually a self-scripted and self-directed farce. The purpose was to create contradictions and gimmicks to attract more fans and clicks. Their behavior was obviously wrong and had a very bad impact on society."
Han Bin took out a document and handed it to everyone. "This is Dong Wenhuan's statement. Everyone can take a look and speak out if you have any thoughts."
"Team Leader Li, tell us about the investigation on your side."
Li Hui sorted out his thoughts. "I've made a statement for the deceased's husband, Zhang Haiqiao. His statement is basically the same as Dong Wenhuan's. It can be confirmed that the suicide was indeed self-directed. As for why Liu Xiaolin suddenly fell, they claimed it was an accident.
"In addition, I've contacted the property management. According to them, the frame of the air conditioner is very sturdy. As long as it wasn't vandalized, even an adult man would be able to stand on it, let alone a woman.
"In summary, I think this case is very likely not an accidental death."
After Li Hui finished, Han Bin looked at Guo Tianxu. "Captain Guo, what do you think?"
Guo Tianxu pondered for a moment. "I agree with Team Leader Li's speculation. However, there is one thing to add. This Huixin Community was built in 2008. It wasn't too long ago, but there was a quality problem last year. The walls fell, the ground cracked, and some property owners had a conflict with the developer. It wasn't a small matter. "
Guo Tianxu was implying that the developer couldn't guarantee the quality of the house, and the property management couldn't be completely trusted. They had to first eliminate the quality problem before they could further determine whether it was an accident.
His words were more subtle and he did not refute Li Hui directly.
Han Bin didn't have that many concerns. "What Officer Guo said makes sense. We have to consider both sides and quickly determine whether it was an accident or a homicide …"
Before Han Bin could finish his words, his phone vibrated. "Buzz …"
Li Hui took out his phone. "Forensics team."
Han Bin raised his chin. "Take it."
Li Hui pressed the answer button. "Hello, it's me."
"Hmm … Hmm … Are you sure? Alright … Alright, alright … I got it … That's all for now. "
Li Hui put away his phone. "The technical team found the metal frame and some accessories of the air conditioner at the site of the corpse. They also found three screws. After testing and comparison, the three screws were found to be used to fix the air conditioner frame."
Han Bin touched his chin and recalled. "I remember there should be six holes on the air conditioner frame. Where did the remaining three screws go?"
Li Hui answered, "The forensics team searched the scene carefully and only found three screws. According to my guess, there are two possibilities for the whereabouts of the other three screws. The first possibility is that they fell somewhere else, such as on the windowsill of a resident on another floor, or they were picked up by a bystander. The other possibility is that someone deliberately removed the screws in advance to create this accident. "
Han Bin said, "According to Dong Wenhuan and Zhang Haiqiao's statements, this suicide attempt was premeditated. It was a joint plan between the three of them. That is to say, both of them knew that Liu Xiaolin was going to jump off the building and would stand on the external fan of the air conditioner. If someone really removed the screw, then these two people are very suspicious."
Guo Tianxu said, "If it's really like what you think, that Dong Wenhuan and Zhang Haiqiao are the murderers, then what's their motive? Murder isn't a small matter. There must be a sufficient motive. "
Tian Li suggested, "Haven't they been recording videos? I think we can check the videos they took before. Who knows, we might be able to find some clues."
Li Hui shook his head. "I've seen a few of the videos they took. There are strong traces of acting, and many of them are made up to attract fans. These things are difficult to use as evidence. If we believe them, it might mislead the police."
Sun Xiaopeng spread his hands. "Aren't the two of them already arrested? If you ask me, we should interrogate them separately. As long as the two of them say different things, the suspect will give himself away."
Han Bin pondered for a moment. "As I said before, this suicide plan was premeditated by the three of them. In other words, the three of them reached a consensus on this matter. It will be difficult to find anything unusual. All the suspect has to do is twist the three screws in advance. The matter is over. As long as there are no witnesses or material evidence, and the other party refuses to admit, it will be difficult for us to prove that they are the culprits. "
Li Hui echoed, "Captain Han is right. If the other party keeps quibbling and refuses to admit, we won't be able to produce evidence to convict them. The key now is to find concrete evidence of the suspect twisting the screws."
"Captain Han, since we're almost done discussing the case, let's not delay any further. Please assign the task."
Han Bin hesitated for a moment, then said, "Team Leader Li, you are responsible for finding the whereabouts of the three screws. Only when we find the three screws will we know whether they were deliberately removed or dropped somewhere."
"No problem."
Han Bin then looked at Guo Tianxu. "Captain Guo, you are more familiar with the situation in Huixin Community. Please visit the community and see if there are any witnesses."
Although the possibility was not high, Han Bin felt that he still had to give it a try.
As for himself, he was in charge of the police station. Once there were new clues, he could interrogate the suspect.
…
Guo Tianxu and his team had a quick meal at a nearby restaurant, then brought them to Huixin Community.
He had been in the Baohua Police Station for many years, so he was quite familiar with the situation in Huixin Community.
Before coming, Guo Tianxu specifically checked the transcript. According to Dong Wenhuan and Zhang Haiqiao, they discussed the shooting theme of suicide by jumping off a building the afternoon before yesterday. In other words, the suspect was most likely to twist the screws from the afternoon before yesterday to the time of the crime.
Of course, this was only the most likely scenario, not necessarily absolute. First of all, Dong Wenhuan and Zhang Haiqiao were certain suspects, so their words could not be completely trusted. Moreover, a plan did not equal an idea. They had made the plan the afternoon before yesterday.
However, the suspect was likely to have this idea long ago and had been planning ahead. For example, he subconsciously guided and hinted Liu Xiaolin to propose the suicide plan by jumping off a building. It was also possible that he had already twisted the screws before proposing the plan. It would be great if it succeeded, but there was no loss if it failed.
After thinking about this, Guo Tianxu had a general understanding of the direction and scope of the investigation.
Guo Tianxu brought his team into the community and saw a few parents playing with their children. He took the opportunity to ask them if they had seen the air conditioner frame of the victim's house in Building 7, if there was anything unusual, or if anyone had touched it before.
He asked a few people in a row, but no one had noticed anything unusual.
This kind of thing depended on luck. No one would stare at someone else's window for no reason.
Guo Tianxu walked in the community and asked along the way. He did not walk aimlessly, but followed the road of the community to the property management company.
The person in charge of the property management company was called Ma Guo Xiang. After seeing Guo Tianxu, he was very polite, "Hello, Officer Guo. Everyone, please take a seat. Xiao Wu, please pour a few cups of tea."
"Manager Ma, you're welcome."
"It's my job. Everyone here works so hard. If I don't even have a cup of tea, I won't be able to live with myself."
Guo Tianxu looked around the office and asked, "Has there ever been an air conditioner frame falling in your community before?"
"No, absolutely not. The property management in our community is absolutely first-class. If there is any problem, it will be resolved immediately. This kind of thing has never happened before."
"Then, what do you think about this incident?"
"I …" Manager Ma was a little embarrassed, "I'm not sure about this."
"When the victim fell, were you at the scene?"
"Yes. After understanding the situation from the security guard, I rushed over immediately. I even went upstairs and wanted to enter the victim's house to persuade her. In the end, the people inside refused to open the door for me. Left with no choice, I ran downstairs." Manager Ma clapped his hands, "In the end, when I went downstairs, the woman fell from upstairs."
"Are you sure she fell? She didn't jump. "
Manager Ma thought for a while, "She fell."
"The victim was standing on the frame at that time?"
"Yes."
"Did she take anything else, like a screwdriver or something?"
"No … I didn't notice."
"After Liu Xiaolin fell, there were a lot of people watching from the side. Did any of these people pick up anything from the scene?"
"What kind of things?"
"For example, screws."
Manager Ma was surprised, "This thing … I'm not sure. At that time, everyone was watching. If you say money fell, someone might pick it up. But if screws are not interlocked, it is useless to pick them up."
"Officer Guo, could this screw be related to the victim falling from the building?"
"I can't reveal the details now. Help me ask around, especially the residents of Building 7. The screws might have fallen onto their windows."
"No problem. I will get someone to ask them later."
Guo Tianxu was satisfied with Manager Ma's attitude. He took the tea from the female staff and took a sip. "Oh, there is one more thing I need to trouble you. Is there a surveillance camera in your neighborhood that can capture the victim's house?"
Manager Ma hesitated for a while, "Oh, now that you mention it, someone reported that someone threw rubbish in Building 7 last year, and it almost hit someone. So, we installed a surveillance camera to see which household threw their rubbish. Who knows, we might be able to capture it."
Small Eyes widened her eyes. "Why didn't you tell me about such an important clue earlier?"
"I've forgotten about it. I don't know much about criminal investigation. If you didn't mention it, I wouldn't have remembered it."
Guo Tianxu was too lazy to get to the bottom of it. The real estate company and the police station were on different sides. They would not do anything more if they could avoid it. "Bring us to the surveillance camera."
"Okay, please follow me. The surveillance room is in the room next door."
After that, Guo Tianxu and the rest entered the surveillance room. A security guard was sitting in the surveillance room, drinking from a big teacup. When he saw Guo Tianxu and the rest walking in, he quickly stood up. "Manager Guo."
"Old Zhao, bring up the surveillance footage from the seventh building and show it to our police comrades."
The security guard, who was addressed as Old Zhao, did not dare to delay. He quickly fiddled in front of the computer and quickly showed the surveillance camera of Building 7.
Guo Tianxu leaned over and asked, "How long can the surveillance camera in your neighborhood last?"
"Our neighborhood has new equipment. Normally, the surveillance camera on the road can only last for a month. The surveillance camera in the sky has a higher requirement for clarity, and the video is relatively large, so it can only be stored for about half a month."
After that, Guo Tianxu arranged for the police officers to look at the surveillance camera in sections. They first looked at the surveillance camera for the last three days, as the suspect was most likely to make a move during these three days.
It was relatively easy to check the surveillance camera because it was fixed. They only needed to keep an eye on the location of the deceased's home.
Under Guo Tianxu's lead, the police officers began the boring work of checking the surveillance camera.
As time passed, Guo Tianxu was a middle-aged man. He had to stand up and move around after sitting for half an hour.
An hour later, he could not sit still anymore. Just as he stood up to move around, he heard Small Eye's voice next to him. "Sheriff, look, someone's out."
Guo Tianxu leaned over and stared at the computer screen. Sure enough, he saw a figure in the window of the deceased's bedroom. Then, he stuck half his body out and bent over just enough to touch the rack of the air conditioner.
"Zoom in on the video and see what he's doing."
Click, click, click. Under Small Eye's control, the video was zoomed in, and the view became clearer.
Big Fool also came over. "This person seems to have something in his hand and is prying on the wall."
Guo Tianxu leaned forward again, afraid that he was not close enough to the screen. "Zoom in a little more and see what it is."
Small Eye fiddled with the screen again and said, "I've zoomed it to the maximum."
The three of them stared at the screen for a while.
Small Eye said, "It looks like a screwdriver!"
"Screw screwdriver, a wrench is more likely to be used to pry the screws on the rack of the air conditioner." Guo Tianxu's tone was a little excited. "It looks like he's twisting a screw. This kid is most likely the murderer."
"Small Eye, play the video to the back. Look at this kid's face." The surveillance camera was placed opposite Building 7. From the current angle, they could only see the general shape of the person, but not his face.
Small Eye continued to play the surveillance video and pressed the spacebar. "He's showing his face."
Guo Tianxu took a closer look and could vaguely recognize that the man was the deceased's husband, Zhang Haiqiao.
'He killed his wife. What a ruthless man.'
Guo Tianxu patted Small Eye's shoulder hard. "Good job, kid. With this evidence, let's see how he's going to deny it."
