Hai Xiaozhou choked again, this is indeed a problem, there must be prerequisites for the use of police force, and after he is arrested, it is nothing more than a few meals and drinks for him, and he still has to be released when he turns back, and the cost has to be borne by the police.

"At present, I have not found that Yan Mengwei is trying to attack others again, and I do not recommend arresting him, which can only cause him to have a greater psychological backlash. "Cheng Li Snow Road.

"But I'm not at ease, how can you guarantee the safety of the judicial officer?" said Hai Xiaozhou.

"There is no need to explain, Yan Mengwei In this world, the only person he trusts the most is me. Cheng Lixue said with a bit of arrogance.

"Well, thank you. ”

Hai Xiaozhou said, quite provocatively handed over a lady's cigarette, Cheng Lixue actually thanked him and took it, and took out a delicate lighter from the small bag, first lit it for Hai Xiaozhou, and then lit it himself.

Hearing that Cheng Lixue entered Fang Chaoyang's house, Hai Xiaozhou was inexplicably unhappy, and she didn't know why, she still came over to see what was going on with this woman.

Hai Xiaozhou found that Cheng Lixue is really a ruthless character, with strong psychological quality, generous, and no stage fright.

No longer continuing Yan Mengwei's topic, Fang Chaoyang said: "I had a phone call with Chi Weiran today, but it's a pity that I didn't ask anything. ”

When he was questioned with Yao Wuyan in the bureau, he didn't give too useful clues, he was very cunning and kept avoiding them. There has been no progress in the falling case so far, which makes people very angry. Shang Yong said depressedly.

"Everyone, should I avoid it?" asked Cheng Lixue.

"No, the facts of the case are all clear, and there are a lot of rumors on the Internet. Shang Yong waved his hand, in this case, the police currently have clues, only Xu Guangyuan's cold corpse.

"Well, maybe I can provide some ideas, don't worry, I'm not going to tell anyone. Cheng Lixue said seemingly seriously.

Hai Xiaozhou didn't speak, obviously not supporting, but Fang Chaoyang nodded and said: "Dayong, it's okay to talk about it, maybe you can inspire some inspiration from another angle." ”

Shang Yong hesitated slightly, but still told the whole case again, the deceased Xu Guangyuan, seventy-three years old, from Fuyu Village, unmarried, and had no relatives. Under the arrangement of the lawyer, he went to the court as a witness, and on the second night of his arrival in Dong'an City, at about half past two in the second half of the night, he fell from the fifth floor of a small hotel.

After analysis by the police, Xu Guangyuan lacked a motive to commit suicide, and the height of the window sill in the hotel room was 1.5 meters, which was not like an old man of his age who could go up, and he still drank alcohol that night. Therefore, it is temporarily listed as a criminal case.

What gave the police a headache was that after careful investigation and extraction of footprints, no other people's footprints were found in Xu Guangyuan's room, and they were not erased, and the traces of Xu Guangyuan's movement were very complete. Moreover, there are footprints on the windowsill of his shoes, which makes the case even more confusing.

The trace experts invited tended to commit suicide, but Shang Yong thought that there were suspicious points in it and did not conclude the case hastily.

"Captain Shang, I think that even if Xu Guangyuan is an old man, with a height of one meter and five, if he tries his best and helps him run, he can climb up. Cheng Lixue got up and measured the height with his hands.

"He drank and walked trembling. Shang Yongzhi frowned, feeling that this psychiatrist was not very reliable.

"No, in the cases of patients I have worked with, there are many cases where the potential of the special situation is stimulated. For example, there was a twelve-year-old child, who was so thin and small that when he had a manic attack, three adult men could not hold it down, and he was extremely powerful. When you drink alcohol, your thinking will be more confused, and you may make wrong judgments. "Cheng Li Snow Road.

"Doctor Cheng, the phenomenon you mentioned cannot be used in the investigation of cases. Hai Xiaozhou interjected.

"If what I'm saying is not true, there will be no trace of the argument that experts are inclined to commit suicide. Cheng Lixue spit out a smoke ring unhurriedly.

"No, Dr. Cheng reminded me that the traces left now, Xu Guangyuan's bare feet, running to the windowsill, seemed to be running. Shang Yong said.

"That's still suicide!" said Hai Xiaozhou.

"Captain Shang, did the deceased have hearing impairments before his death?" asked Cheng Lixue.

"Yes!"

"In the courtroom, because I couldn't hear clearly, I even had to leave the table for questioning, close to my ear. Fang Chaoyang added.

If so, he wouldn't hear the sound of the lock being unlocked, and he wouldn't be alarmed. Cheng Lixue analyzed.

"If someone opens the door, why don't they go inside?" Shang Yong asked.

"You don't need to go into the house to avoid leaving traces. ”

"Doctor Cheng, according to your speculation, if there is a murderer, he stood in front of the door and forced Xu Guangyuan to jump off the building?" Shang Yong was also incredulous.

"Imagine if a person was asleep and suddenly saw a female ghost with long hair and a tongue standing open? Cheng Lixue boldly speculated.

"No, since Xu Guangyuan has a hearing impairment and doesn't know when the door opens, how can he wake up?" Hai Xiaozhou disagreed with Cheng Lixue's subjective inference.

"There are other ways to do it. For example, use a fast-eliminating irritating gas to wake up a person in his sleep, and by the time the case is investigated, it will have already volatilized. Cheng Lixue said again.

Hai Xiaozhou was stunned, and grabbed his hair hard, as if it was okay!

This inference is very interesting, worthy of a psychiatrist. Shang Yong's eyes lit up and he praised it.

"I've also studied criminal psychology and I'm not very proficient. "Cheng Li Snow Road.

"Someone pretended to be a ghost, causing Xu Guangyuan to jump off the building in a panic, if this is the case, it is a high-IQ crime. Hai Xiaozhou nodded.

"It can't be regarded as a high IQ, maybe, the murderer just wanted to scare Xu Guangyuan to death from a distance, causing sudden death, but he didn't expect him to jump off the building. A suit of white clothes, a mask, some blood stains, and a cyan glow stick suddenly appeared, causing a great deal of horror. Cheng Lixue continued to analyze.

"However, how did the murderer know the room Xu Guangyuan was in?" Fang Chaoyang asked.

"This is not difficult, Xinglong Hotel was on duty that day only the proprietress of the hostess, the method of recording is very traditional, with a ballpoint pen and a notebook, while she went to the toilet, took a book in the window, who lives where, it is clear. Shang Yong answered this question, and said helplessly: "It doesn't cost much to install a set of monitors, and this hotel doesn't have it." ”

"It's not easy to find such a hotel, I think, Xu Guangyuan went there to live, and someone recommended it, and even led it. "Cheng Li Snow Road.

"This matter still needs to be investigated, and he may take a taxi over. Shang Yong said.

"If there is a murderer, he may live nearby, after the jumping incident, he took off his clothes and wrapped it, and left quickly as soon as possible, walking the hall is easy to be found, and he can jump off the second floor to leave, and he is sensitive. Cheng Lixue said again.

"Awesome! The police really need a talent like you!" Shang Yong said sincerely, and then got up, "Xiaozhou, no, I'm going to take someone to Xinglong Hotel to have a look." ”
