When Tian Chunda, captain of the Nanshan City Criminal Investigation Detachment, rushed to the "Baiyun Apartment" from his home, it was 10:35 p.m. When he took the elevator to the fifth floor, the ruddy-faced detective Hao Dong was standing in front of the door of the crime scene and beckoning to him.

"Captain, here!"

Hao Dong: They have just arrived. In front of the door of room 505, in addition to the two policemen, there was also a man and a woman who were about 25 years old, looking very uneasy. The woman wears a hazel dress and a white coat, and is a sexy and easily attractive woman for men. Her face was pale, very haggard, and her long hair was disheveled, as if she was in such a hurry that she didn't even have time to comb it. The man was wearing a short-sleeved shirt, as if he had come straight from work in the company, and he had a strong physique of an athlete type, and his forehead was covered with sweat, as if he had just had a fierce exercise.

"You are ......"

As soon as Tian Chunda asked, the man took a step forward and said, "I am a colleague in this homeowner company, my name is Zhong Kuan." This is Zhong Kuan's fiancée Tong Jun. ”

He said as he pointed to the woman beside him.

Tian Chunda left an impression in his mind: Zhong Kuan, a man, has a sense of lightness.

"Someone called the police and there was a murder here." Criminal Police Officer Hao Dong pointed to the door and said.

"Hasn't anyone been in yet?"

"Because the door is still locked." Hao Dong said, pointing to the handle.

"Hmm......" Tian Chunda's eyes were buried in wrinkles, and on his square face, the thick eyebrows were twisted into a knot. He looked at Tong Jun and asked, "Are you his fiancée, don't you have the key?" ”

"I didn't." She nodded apologetically.

It's a newly built apartment and there's no bulletin box on the door. Because it's a private room, there won't be a spare key from the caretaker. It seems that I have to smash the door, maybe it is better to smash the window pane from the balcony.

Tian Chunda instructed Hao Dong to go around to the balcony with a policeman and smash the window panes. Hao Dong got permission from the residents of room 504 next door, and when he climbed over the wall of the balcony to go to the balcony of room 505, Tian Chunda carefully observed the door and inspected the keyhole, which was a magnetic lock, the kind that ordinary thieves could not open.

As he was saying this, the sound of unlocking came from the back of the door, and Detective Hao Dong revealed a pale face from the open door.

"Captain, what a murder!"

"Is the door on the balcony side locked?"

"Locked."

"Is there a chain on the door?"

"Nope."

"Let's go in and have a look."

As soon as Tian Chunda walked into the room, Hao Dong pointed to the center of the living room. A man in a shirt lay on his back under a table, his eyes bulging as if they were about to pop out, apparently dead. It was observed that the deceased had no stab wounds on his body and was bleeding around his neck, most likely strangled to death.

The room was two suites, and no murderer was found. There is a round hole in the window pane of the bedroom, which is where Hao Dong and the others reached in to open the window and enter the house, so the door on the side of the balcony was locked well. In short, the murderer disappeared from the room without a trace.

"Hey, no, don't go in!"

A policeman's shout came from behind. As soon as Tian Chunda turned around, Tong Jun, who was pale, stood at the door of the living room with his hands covered his mouth.

"Zeng Yuan, you're scary, aren't you? You're just sleeping, aren't you? Uh, you get up, I'm scared to death! ”

Tong Jun staggered like a ghost and tried to walk towards the corpse, but as soon as his legs went limp, he was about to fall. Zhong Kuan hurriedly supported her and helped her sit on the sofa.

"Is this person definitely Zeng Yuan?" Tian Chunda asked.

Zhong Kuan nodded and replied, "Yes." ”

After letting the unconscious Tong Jun temporarily sleep on the bed in the bedroom, in order to learn more about the situation from Zhong Kuan, Tian Chunda took him to the elevator.

When Tian Chunda pressed the button to descend, Zhong Kuan said, "Hey, I'm really scared. My friend died, and I really didn't know what to say. ”

Zhong Kuan said, as if he had just exercised, with a relaxed expression, and it was difficult to see the sadness of his loss of a friend.

Zhong Kuan briefly told Tian Chunda about the process of rushing here.

"Tong Jun is my ex-girlfriend. I was sitting at home drinking tea after dinner, and Tong Jun called me. She anxiously said that Zeng Yuan might have had an accident at home. I asked what was wrong? She said that she was talking to Zeng Yuan when she heard him scream, 'Ah! Then it went silent, and when I called again, the bell rang and no one answered. So she called me and asked me to go with her to Zeng Yuan's house to have a look, but she didn't dare to go alone, because I had a car. I drove her up and came to Zeng Yuan's house. When I arrived at Zeng Yuan's house, the door was locked, and no one answered the door. I asked Tong Jun to go to the nearby police station to report the case, and I went to the apartment manager to ask for the key. But the caretaker didn't have a key either. ”

"So, Tong Jun has broken up with you, and you drove here to help her?" Tian Chunda said. "You're very open-minded!"

"There's no way around it. If she asks me, I can't refuse. Even if it's a woman who dumped me......"

"When your rival was killed, your mood should be said to be very complicated."

"Zeng Yuan and I are not the kind of antagonistic relationship called rivals in love. Tong Jun just thought that Zeng Yuan was better than me so he chose him, and I was also an adult, so I withdrew without hesitation. She's not the only woman. ”

The two took the elevator down to the first floor.

"But now that her fiancé is gone, what will happen to her in the future?"

Tian Chunda stepped out of the elevator and walked towards the door of the apartment, standing next to a large tree potted plant. He looked at Zhong Kuan and said, "You may still have a chance." ”

"Hey, if only that's the case."

Nakakuan smiled, but perhaps feeling that he was not cautious after all, he glanced around and closed his mouth.

It was only at this moment that Tian Chunda noticed that the mailbox in room 505 was slightly open. He put on his gloves and opened the mailbox to see that there was no mail in it, only a few pieces of advertising paper, and when he pulled it out, something fell to the ground. It's a key. After Tian Chunda wrapped the key in his handkerchief, he immediately ran into the elevator. Zhong Kuan also hurried behind.

After Tian Chunda asked Hao Dong to lock the door of room 505 from the inside, he inserted the key into the keyhole from the outside. With a "boom", the door lock opened.

Tian Chunda thought: The key found in the victim's mailbox is undoubtedly the key to the door of room 505. That is, after committing the murder, the murderer locked the door of the house, and then put the key in the mailbox on the first floor when he escaped from the apartment.

Because it was discovered early, Zeng Yuan's time of death was limited to one hour after 8:30 p.m. This is basically the same time as Tong Jun's call to Zeng Yuan. Tong Jun found that Zeng Yuan's situation was different, and then called Zhong Kuan for help, which was about 9 o'clock. About 20 minutes later, Zhong Kuan drove a car to pick her up. The two rushed to Zeng Yuan's apartment before 10:30 p.m., and when they saw that no one answered in the room, they immediately called the police. As soon as Tian Chunda and the others received the report, they immediately rushed to the scene and arrived at 10:30.

According to colleagues, Zeng Yuan left the company at 7:30. It is assumed that he returned home at around 8:30 a.m. He was concentrating on answering Tong Jun's phone call when he was hit in the back of the head with a hard object, and when he was feeling groggy, his neck was wrapped around a rope or something. The rope around his neck forcibly took his life. The cause of death was asphyxiation. Zeng Yuan had struggled to the death. can hold him down, it seems that the murderer is a very powerful person. The top button of the victim's shirt was pulled off, and a shoe was broken off his foot.

There were no traces of a fight in the room, and it is estimated that the murderer was most likely an acquaintance of the deceased.
