At two o'clock in the morning, the police at the police station received a report that they had seen a ghost in the community.

That community is the community where Zhang Qiaowei lived before his death, and the room where the ghost was found is the room where Zhang Qiaowei lived before his death. Because of the strange incident, the police station notified the criminal police team, and the criminal police team notified Liang Zhijie and Li Fei. When the two of them arrived at the community, it was already 2:45 in the morning.

The informant was a young girl who had just graduated from university and was working in finance for an information technology company. Because there was something wrong with the accounts, she checked herself in the company at a little more, and when she left, it was 1:28 points. She didn't count the time on the road, and it shouldn't have been more than fifteen minutes under normal circumstances.

The little girl is a foreigner, went to college in Jiangcheng City, and joined the current company after graduation. The house was rented by her only three days ago, and as soon as she moved in, Zhang Qiaowei fell from the building. Coincidentally, she happened to live on the floor below Zhang Qiaowei.

Because she was afraid, when she walked to the place where Zhang Qiaowei fell from the building, the little girl hesitated slightly. The light in the corridor seemed to be broken, flickering and flickering, and the little girl did not dare to go in, so she ran to the doorman and begged for security.

It takes three minutes to walk from the gate to the building rented by the little girl, and it should take no more than five minutes for two people to talk. When there was still some distance from this building, the little girl found that a room upstairs was abnormal, and when she looked closely, it was Zhang Qiaowei's house.

"The first thing you saw was a silhouette of a man?" Li Fei made a record: "Who saw it first?" ”

"I saw it first!" The little girl raised her hand, her face was still a little pale because she was frightened: "At that time, most of the people in the community were asleep. I was afraid to always glance at that upstairs because I knew that there was someone dead on the upper floor. I was very entangled in my heart, I was afraid of what to see, and what I wanted to see, whether I was sick in my heart and had to see a psychiatrist. ”

"I'm not sick, I'm like that." Li Fei hurriedly comforted: "Tell me what you saw?" ”

"The lights were on in the room, the curtains were floating, and I guessed that the windows on the upper floor were open. The first time I saw it, there was nothing, and I didn't go upstairs to my house to think about it. When I looked up the second time, I saw a shadow. ”

"What kind of shadow?"

"Silhouette!" The little girl stood up and demonstrated: "It's like a silhouette like this." ”

"A man standing sideways in front of a window?"

"Yes, yes, that's what it feels like. I was still wondering, wondering who got up in the middle of the night to dry my clothes. Later, I thought that maybe it wasn't drying clothes, but I woke up in the middle of the night and couldn't sleep, so I ran to the balcony to breathe. As you can see, the living room and balcony are connected. ”

"And then?"

"I blinked, and the man stood in front of the glass in a very strange pose." The little girl adjusted her posture and asked the security guard, "Big brother, do you think I am learning well?" ”

The little girl's posture is indeed very strange, like a gecko, and like the kind of person who is beaten to the wall in a film and television drama.

After getting a response from the security guard, the little girl opened her mouth again: "That's what it looks like!" It was strange enough, but the man was still writhing on the glass, and the more he twisted, the stranger it became. Later, I heard from the security guard that it was Zhang Qiaowei's house. Zhang Qiaowei is the teacher who fell from the building, the one who lives upstairs in my house. I looked at it more and more, and counted it carefully, and it was really her house. Then I pulled the security guard to call the police. ”

"It's right to be security-conscious, and it's right to call the police." Li Fei gave a thumbs up to the little girl: "There is no ghost, don't scare yourself, that is a burglar." ”

"Did something happen to that thief?" The little girl asked uneasily: "I see people in white, and on TV, such people are usually forensic doctors." The medical examiner only appears when the dead are dead, is there a murder case upstairs? ”

"If so, are you afraid?" Li Fei asked, unable to bear to tell the little girl the truth: "If you can, let's change the house." ”

The little girl was about to cry, she looked at Liang Zhijie, her nose twitched: "Bet one and pay three, I have rented it for half a year, and if I move now, the landlord will not refund the money." I just graduated, and my parents paid for the rent. Forget it, people are so poor, what the hell are you afraid of? ”

"Is there a phone number from the landlord? I'll help you talk to the landlord. Liang Zhijie spoke: "Let the security guard help you ask if there are any other houses for rent in this community, stay away from this one." ”

The little girl nodded and thanked Liang Zhijie.

Upstairs, the medical examiners are investigating.

Liang Zhijie walked in with Li Fei and asked the forensic doctor who was busy: "What's the situation?" ”

"The circumstances at the scene of the crime are a bit simple, but the case itself may be a bit complicated." The forensic doctor handed Liang Zhijie an ID card: "The identity of the deceased has been confirmed, and he is a thief with a criminal record." Zhu Chengfeng, male, 37 years old, habitual thief. The cause of death was poisoning. ”

"Poisoned?"

"Yes, poisoning, I can't tell you exactly what poison it is, but it's very likely that the murderer extracted it from some kind of plant." The medical examiner pointed to the corner of the deceased's mouth: "The poison was poured into it, and the deceased struggled slightly, leaving something on the corner of his mouth. In my experience, it's not like the usual ones on the market. This murderer has a technical level. ”

"You forensic doctors can boast like that?" Liang Zhijie went to see the condition of the deceased: "His expression is a little strange! ”

"Frightened, extremely frightened, he might have seen something strange here." The forensic doctor spreads his hands: "For example, a murderer who pretends to be a ghost, or a murderer who looks like a ghost." In short, he was frightened, and his abnormal behavior was coerced after being frightened. Also, there were three people at the scene of the crime, although the footprints are not clear, it can be determined that in addition to the deceased Zhu Chengfeng, there are two other men. ”

"Three?"

Not only Li Fei was surprised, but Liang Zhijie was also surprised.

"I can understand the thief in Zhang Qiaowei's house. Xu wanted to take advantage of the death of the head of the household to come to the house to steal something valuable. Who are those other two people? What was the purpose of them coming to Zhang Qiaowei's house? ”

"I don't know who the other two are, but I can only tell you that one of them is hidden in the hostess's cupboard." The forensic doctor led Liang Zhijie and them into the master bedroom, opened a cabinet door, and pointed inside: "The male is between 1.75 meters and 1.8 meters tall, and his body shape is average, about 130 pounds, and he forced himself into it." This person is not in good health, his spleen and stomach are weak, his hair is oily, and he has hair loss, there are strands of hair that he has fallen out, I have already taken some of it, and when you and Li Fei find the suspect, you can do a DNA to determine his identity. ”

"Is it the murderer?" Li Fei picked up a hair from the cabinet, it was indeed very oily, it was not Zhang Qiaowei's, nor her boyfriend's.

The murderer was not the one hidden in the cabinet, but the third person who entered Zhang Qiaowei's house. This person may have witnessed or heard the whole process of committing the crime, because he left after the killer left.

Also, the burglar entered the room through the lock-picking technique, and this person entered the room through the key, as for how the murderer got in, it is possible that the second person did not close the door after entering.

That's why the forensic doctor said that the facts of the case are very simple, and the case is very complicated.
