Serious Crime Unit 1

Chapter 981 Falling from the Building (5)
"Have you ever been to Zhang Huaiyou's bedroom after you returned home?"

"No, after I took a shower, I went back to my bedroom to sleep."

"Does Zhang Huai have the habit of sleeping with the window open?"

"No, no matter how hot it is, he won't sleep with the window open. Although there are no precious things at home, a mobile phone is worth several thousand yuan. He is afraid of thieves, so he always sleeps with the window closed."

At this time, Wu Jiang and Xiao Ke had completed their investigation and walked out of the bedroom. Jiang Yiming wanted to ask them what they had gained, but because Zhang Yu was there, he held back.

"Ms. Zhang, that's what we're talking about today. This is my business card. If you think of anything suspicious, please call me. My phone is on 24 hours a day. Goodbye, please take care of yourself." Jiang Yiming saw her After nodding, she walked out of her house.

After returning to the car, Jiang Yiming asked Wu Jiang what he had gained?Wu Jiang said: "Xiao Ke and I extracted 30 shoe prints at the scene. Preliminary analysis showed that they belonged to four people. One of them was a female shoe print. I thought it belonged to Zhang Yu. I took Zhang Yu's shoes Let’s compare, it turns out it’s hers, there’s another shoe print that belongs to Zhang Huai, and I don’t know who the other two are.”

"I heard that Zhang Huaiyou has a good relationship with Ouyang Di. Could one of the shoe prints be his?"

"This needs to be verified by Ouyang Di. We also extracted four different fingerprints on the bed and bedside table. After comparison, two of the fingerprints were the same as those on the estazolam bottle. They belonged to Zhang Huaiyou and Zhang Yu The other two belong to whom I don’t know.”

"Are there any signs of damage to the bedroom windows and doors?"

"The windows and doors are intact. The bolts of the windows and doors are plugged in from the inside. People from outside cannot get in. The door lock of the bedroom is a refined copper lock that can be locked from the outside with a key. It cannot be opened by ordinary people. That means the bedroom is a complete secret room.”

"We know that there are hundreds of secret rooms that can be forged, and there are many ways to crack them. If the windows and doors are not locked, the murderer sneaks into the bedroom, replaces the estazolam in the medicine bottle with triazolam, and then changes it from estazolam to triazolam. To escape from the window, he only needs to tie the latch head with fishing line, close the window and door, and pull the fishing line down outside the window. Under the action of force, the latch will insert into the bayonet, and then release the fishing line, and it will When it is loosened naturally, the murderer can pull away the fishing line and complete the creation of the secret room."

"Yes, you are right. It is very simple to create such a secret room. However, we don't know whether the window was closed before the murderer entered the bedroom. If it was closed, how did the murderer pull the latch and open the window and door? "

"It is difficult to open locked windows and doors...but Zhang Huaiyou is no longer alive. He cannot tell us whether he locked the latches of the windows and doors when he left home to go to Sanjiang Hotel for dinner on the evening of June 6. If not, he , then let the murderer have an opportunity. We don’t care how the murderer entered the scene, as long as we arrest the murderer first, everything will be solved. "

"Well, as long as this is determined to be a murder, it is only a matter of time before the case is solved." Wu Jiang was very confident. In fact, everyone in the crime team was so confident.This is very important, if you don’t have confidence, you can’t accomplish anything.

"Did you extract any tiny biological samples at the site?"

"The site is very dirty and may not have been cleaned for a long time. However, we have extracted some hair, dander, nails, sweat stains, sputum, etc. If we want to conduct DNA identification and comparison on these samples, it will take time. We will do it in a while. Don’t come out.”

Jiang Yiming nodded.

"What are we going to do next?" Xiao Ke asked.

Jiang Yiming was about to answer Xiaoke when Lu Yingying and Wen Xiaorou came towards them. Lu Yingying said to Jiang Yiming: "Team Jiang, we checked the distribution of the surrounding monitors. The closest one to here is the security monitor 200 meters away. , however, there are three security monitors further away, these four monitors surround the scene, and the suspect must pass through these four monitors to enter the scene."

"However, there are many people passing through these four monitors, at least thousands, and we don't know who the murderer is or when the murderer entered the scene to commit the crime, so we don't know where to start the investigation." Wen Xiaorou explain.

"You first check the surveillance video, and we will investigate Zhang Huai's social background to see who has the motive for the crime. Then we will conduct an in-depth investigation. If we find the suspect and compare it with the person you found, we may find the murderer. , so your work will not be in vain." Jiang Yiming encouraged Wen Xiaorou.She nodded, thinking he was right.

Jiang Yiming and Zhou Ting went to visit Ouyang Di.Because he and Zhang Huai are so close, he must have a better understanding of Zhang Huai's situation.

Zhou Ting called Ouyang Di and asked where he was and that they wanted to visit him.He said at home.He lives on the 21st floor of No. 1 Luogu Lane, Liangcun.

Zhou Ting called Liu Xiaoqing again and asked him to lead the way, because he had been a policeman in Liangcun and knew the streets and alleys of Liangcun well. Moreover, he knew Ouyang Di and could find Ouyang Di's residence faster.When Zhou Ting and Jiang Yiming arrived at Liangcun, Liu Xiaoqing was already waiting for them at the entrance of the village. After politely shaking hands and greetings, Liu Xiaoqing took them to No. 21 Luogu Lane.The alley is very narrow, about two meters wide. Although it is a sunny day, the light cannot shine in from the densely packed high-rise buildings, so the air is full of moisture.

They soon arrived at their destination. The door on the first floor was locked. Liu Xiaoqing walked to the glass window, stretched out his hand and knocked on the glass, shouting: "Ouyang Di, we are here, please open the door."

The glass window was opened, and Ouyang Di stuck his head out. After seeing them, he ran to open the door. After the iron door on the first floor was opened, they walked in and arrived at Ouyang Di's residence.

This is a set of two bedrooms, one living room, one kitchen and one bathroom. There is a painted red wooden sofa and a glass coffee table in the living room. There is a computer and a 22-inch display screen on the rectangular table opposite. They are stacked in the corner. holding some mason's tools.

After Ouyang Di entered the door, he pressed the switch on the wall and the lights came on, illuminating the dark room.He invited Jiang Yiming and Zhou Ting to sit on the sofa, then took out two folding chairs, opened them, placed one of the chairs behind Liu Xiaoqing, and invited him to sit down. He sat opposite Jiang Yiming and said, "The conditions are not right." Okay, police officers, please bear with me."

"You're welcome. We're here to learn about the situation from you. Please cooperate." Jiang Yiming said.

"I will cooperate well." He replied with a smile, his expression was humble, restrained, and even a little uneasy.

"Don't worry, just tell the truth...Why didn't you go out to work today?"

"Master Zhang's death left a big shadow in my heart. I don't want to do this anymore. Zhang Yu asked me to help her deal with Master Zhang's funeral. I agreed to her, so I just took a few days off. Let’s go back to the construction site after everything is done...Excuse me, how can you hand over Master Zhang’s body to Zhang Yu?”

"We have completed the autopsy. Zhang Yu can transport Zhang Huai's body back at any time. Through the autopsy, we found that he had an overdose of sleeping pills in his body. It was these sleeping pills that made him dizzy and caused him to fall to his death from the sixth floor. So, we came to investigate.”

"What? Could it be that Master Zhang was murdered?" He was surprised. He straightened his back involuntarily and retracted his feet.

"Yes, we judge it to be homicide. You worked with Zhang Huaiyou day and night, and you are brothers. You should know his situation very well. Do you know who he offended?"

"I don't know. Master Zhang has a good temper, is kind, and has a broad mind. He rarely has any friction with others, and he is even less likely to offend others." There was sadness and anger in his tone. He didn't expect that Zhang Huaiyou would be betrayed by others. murder.

"I heard that Zhang Huai and Zhang Yu were at odds with each other. Is this true?" Jiang Yiming thought of the two of them sleeping in separate beds and thought that there must be something wrong with their relationship.

"This...I'm not sure..." He answered hesitantly.

"If you feel that Zhang Huai and you are as close as brothers, then tell us the truth. Don't you want us to arrest the murderer and redress Zhang Huai's grievance?" Jiang Yiming saw that he was deliberately avoiding the question. .

"Well, how should I put it? The relationship between Master Zhang and Zhang Yu is really not good. One time Master Zhang was drinking at my house, maybe too much. He told me that Zhang Yu might have an affair with Teacher Wu Huanhuai from Xiaokeng Primary School. , he once questioned Zhang Yu, but Zhang Yu refused to admit it.

"Later, Master Zhang often took advantage of rainy days to go to Xiaokeng Primary School to spy on the situation. One day, he saw Zhang Yu and Wu Huanhuai walking on the playground holding the same umbrella. This made Master Zhang very angry. He rushed forward and shook his fist. Then he called Wu Huanhuai.

"Wu Huanhuai was 55 years old, and his body was relatively thin. He was knocked to the ground by Master Zhang, who was extremely strong in arms. It took him a long time to get up. After Master Zhang took Zhang Yu home, Zhang Yu quarreled with him, and Zhang Yu started to divorce Master Zhang. , Master Zhang was heartbroken when he heard it. What he feared most was divorce.

"In the end, Master Zhang completely surrendered, because he knew deeply that as soon as he got divorced, his two children would lose the warmth of the family, and what he loved most were his two children. Of course, after the divorce, he wanted to marry Zhang again. It is impossible to have a wife as beautiful as Yu, so Master Zhang compromised." At this point, Ouyang sighed.

"What kind of person is Wu Huanhuai?"

"I don't know about this. Master Zhang said that he was the vice principal of Xiaokeng Primary School. He divorced his wife and gave birth to a daughter. He was married and had children. After this happened, Zhang Yu and Master Zhang slept in separate beds. , However, Zhang Yu still helps Master Zhang with laundry and cooking, fulfilling the responsibilities of a wife."
