Criminal Investigation Chronicle

On August 2016, 8, the Yanjing Police Station received a report that a bankrupt real estate developer was found dead in a building under renovation. It was judged that the deceased was killed in a room under renovation. Located on the sixth floor.The room was locked, and the windows were also locked, and the key to the room, after understanding, was only available to the decorators who were under construction. It was a murder in a secret room.

"The deceased Zhao Xuezhong, male, 47 years old, 1.7 meters five, weighing 78 kilograms, was found dead in a room under renovation on August 8. The cause of death was that the right wrist artery was cut, causing massive bleeding, and a lethal amount of sleeping pills was found in the stomach. , Part of it has been digested, and the time of death was between 20 am and [-] am, and no other people's footprints, fingerprints, etc. were found at the scene, and there were no obvious signs of fighting." Forensic doctor Xiaomei said.

"A room that is being renovated, many workers go in and out of the construction every day, but no fingerprints or footprints are found. The room has obviously been cleaned. I asked, those decoration workers usually start work at eight o'clock, the murderer after the murder Have enough time to clean up the scene, and then leave calmly." Zhao Lei analyzed.

"Captain Zhao, the family members of the deceased have arrived," said the colleague.

The wife of the deceased Zhao Xuezhong, Lin Xiaofeng, was a middle-aged woman in her forties. She was fair-skinned and beautiful, and well maintained. It can be seen that she was a great beauty when she was young.

"When was the last time you saw the deceased?" the officer began to ask.

"Around five o'clock this morning, Lao Zhao got up very early and said he was going to visit the construction site. In fact, since he went bankrupt at the beginning of the month, the construction site did not belong to him and was mortgaged to the creditor. However, Lao Zhao has been like this for these years. Every day Get up early, go to the construction site first and then go to work in the company." Lin Xiaofeng covered his face with his hands, weeping slightly.

"How is your relationship as a couple?"

"We have a very good relationship, so I followed Lao Zhao. He was a poor boy at that time. After years of hard work, we saved a lot of savings. However, in the past two years, business has not been going well, continuous losses, and the company is unable to make ends meet. Finally At the beginning of this month, the company filed for bankruptcy, our house and car were all mortgaged, and we are still renting in a private house in the suburbs of Beijing."

"How far is it from your home to the construction site where Zhao Xuezhong was killed? What kind of transportation does Zhao Xuezhong usually take?"

"It takes about four to 10 minutes by car. Lao Zhao always goes out by bus during this time."

"Has Zhao Xuezhong had any enemies, or has any grudges with anyone?"

"That's not true. Lao Zhao has always been kind to people, caring for his business partners, and caring for his subordinates. When the company is running well, the employees get a lot more money than other real estate companies. You can ask about it. His popularity very good."

"Then, did Zhao Xuezhong have anything unusual these days, or did he receive any strange calls?"

"It's nothing unusual. The phone calls. There are people demanding debts every day, but it's not like killing people just because they haven't paid their debts."

"Zhao Xuezhong sent you a WeChat message in the morning, why didn't you reply?"

"What about WeChat? I sold my mobile phone a few days ago. The elderly phone I use now is difficult to make and receive calls and send text messages. It's not like Lao Zhao doesn't know how he sent me WeChat." , Lin Xiaofeng took out the mobile phone she used, it was indeed a basic function phone for the elderly.

After Lin Xiaofeng left, the bureau began to discuss the case. "After investigation, what Lin Xiaofeng said is true. This Zhao Xuezhong is indeed a character. He started from scratch more than 20 years ago. He started as a small worker on the construction site and was particularly able to endure hardship. He became a small contractor, and then became the owner of a construction company. The boss of the development company, who was once worth more than a billion yuan, but in the past two years he has been very troubled, where the development has lost money, resulting in a breakdown of funds, unable to recover the capital, and filed for bankruptcy at the beginning of this month. During this period of time, he was very poor. The sky fell to the ground, several villas and luxury cars were all mortgaged, and his wife’s mobile phone was sold. We checked his recent call records, and there was nothing special. They went to the construction site early in the morning. The relationship between Lin Xiaofeng and Zhao Xuezhong has always been very good. After all these years, Zhao Xuezhong has treated Lin Xiaofeng as before. They have a son who is studying in Yanjing. His grades are very good and he is very low-key. It's not as unreliable as ordinary rich second generations." Interpol Lao Xu said with the investigation materials.

"In this way, the preliminary judgment shows that the murderer knew Zhao Xuezhong's life pattern, followed Zhao Xuezhong to the construction site, or waited for a chance to subdue Zhao Xuezhong, gave him a large amount of sleeping pills, cut his wrists, and cleaned up the scene before the workers went to work in the morning. Let's go." Zhao Lei said.

"How did the murderer create the secret room?" asked the police officer next to him.

"After on-site investigation, a certain amount of water stains were left on the windows of the room. The murderer only needs to turn over to the window after committing the crime, use a piece of ice to hold the handle for locking the window, and use the cable car hanging outside the window After the ice melted, the window handles hung down and locked. I asked the person in charge of the construction site, and there was indeed a cable car that was originally working on the upper floors and went down to the first floor, but there were no useful footprints around. Of course, these are inferences However, after asking Lin Xiaofeng, I had a feeling that Lin Xiaofeng was too calm. Judging from the evidence I had, Lin Xiaofeng and Zhao Xuezhong had a very good relationship. After the company went bankrupt and her husband died, the middle-aged Is there something wrong with the performance of the beautiful woman? What do you think?" Zhao Lei asked after finishing speaking.

"Captain Zhao, do you mean that Zhao Xuezhong's death was related to Lin Xiaofeng? Or did Lin Xiaofeng hire a murderer to kill him? According to the nearby monitoring, Lin Xiaofeng did not leave the house between the time when Zhao Xuezhong went out and when we notified her."

"This is also my speculation. Maybe Lin Xiaofeng is the kind of person who can't show his emotions, but this line can't be relaxed. Check Lin Xiaofeng, including recent movements, calls, relationships, and people you have seen recently. Check it out." After Zhao Lei finished his instructions, he took out the piece of paper and added: Sending WeChat to forge the rules of life in the secret room.
