crime profiler in the dark

"I heard it was in the elevator. There were other people in the elevator at the time. The murderer was so daring!"

Hearing this, Sergeant Xu didn't care that it was already 02:30 in the morning, so he dialed Sergeant Zhu's phone. After it rang for a while, Sergeant Zhu's confused and complaining voice came from the other end of the phone:

"Do you know what time it is?"

"Old Zhu, did you take a throat-cutting case last week?" Sergeant Xu asked urgently before he could explain.

"Yeah, what?"

"I'm in a movie theater right now and there's a victim with his throat slit."

"What? Are you in the elevator?" There was a "click" sound from Sergeant Zhu turning on the bedside lamp on the other end of the phone, and his voice became more sober.

"No, it's in the screening room. What are the other characteristics of your scene?" Sergeant Xu wanted to make sure that it was the same person.

"Nothing else."

"Are there any suspects?"

"The murderer was wearing a hat and deliberately avoided the surveillance cameras. Witnesses also gave different descriptions of him. There are very few clues at present."

"I asked my subordinates to take the surveillance video, maybe it's a serial murder case." Sergeant Xu said seriously.

"Tell me any news." Sergeant Zhu also felt the same way.

At eight o'clock in the morning, Sergeant Xu had already arrived at the support department. Although he had asked his police officers to check the deceased's social relations, whether there were any enemies or rivals in love, his intuition told him that the murderer and the victim were not the same. There is no connection, this is just an indiscriminate homicide case, so he doesn't hold out much hope, he just hopes that the support department can find the physical evidence clues left by the murderer.

Sergeant Xu first went to the forensic department. Liu Jiajie, the forensic doctor on the evening shift, had already completed the forensic report. There was no special place mentioned in the report, and then he went to the technical support department. The surveillance video of the movie theater was sent here at three o'clock in the morning. It stands to reason that there should be results. When he arrived, he happened to meet technicians Xiao Cheng and Xiao Guan. Xiao Cheng, who was on the night shift, saw Sergeant Xu coming and said:

"The surveillance cameras in the arena are not effective, especially because they are located at the back. People can be photographed, but their faces can't be seen clearly; the surveillance video outside the arena did not record the murderer's appearance. He obviously avoided it on purpose. The monitor, but according to the length of the shadow projection, his height is basically calculated. In addition, I think he should have stepped on a movie theater before, so he matched his height and body shape with people who have been to the movie theater within three months. Homework The amount is huge, I handed it over to Xiao Guan, and there may not be any results in a while."

"Thank you both." The murderer left too little information, and this was the only clue.

"This is his height information, I hope we can find the suspect." Xiao Cheng handed the printed information to Sergeant Xu.

The information is a printed photo, which is the clearest photo Xiao Cheng found. In the photo, a man wearing a baseball cap is facing the monitor, standing in front of the self-service ticketing terminal to buy movie tickets. It reads: According to calculations, the suspect is about 1 meters tall and of medium build.

Sergeant Xu wondered, "Why is there only a back view? Isn't there a frontal photo of him?"

"No." Xiao Cheng shook his head and said, "I've been watching for a long time, but I didn't see him coming out. The murderer should have left through a safe passage without a monitor. Tickets can only be collected at the front door, but the whole process is only from the back." Although Xiao Cheng has tried his best, but it is of little help to Sergeant Xu.

Sergeant Xu was a little discouraged. He asked the ticket inspector before, because it was too late, and the ticket inspector was also very sleepy. He just looked at his ticket casually, and didn't pay attention to the other person's appearance at all.

Then Sergeant Xu went to the hidden trace inspection office and the fingerprint inspection office, but unfortunately found no useful information. Sergeant Xu was disappointed and was about to go back to the third floor when he saw Bai Haolin coming out of the elevator. He called stopped him:

"Hey, Xiaobai."

"Inspector Xu, so early?" Bai Haolin had cooperated with Inspector Xu on some cases before, and the two parties were quite familiar with each other.

"I received a case early this morning, let's take a look at the situation." Sergeant Xu blinked his dry, red and swollen eyes due to lack of sleep.

"What case?" Bai Haolin knew that Sergeant Xu was impatient.

"Throat cutting case." Sergeant Xu looked at Bai Haolin meaningfully.

"Is the case complicated?" Bai Haolin saw some information in Chief Xu's eyes: anxiety and impatience, it seems that the case is quite difficult.

"It's not complicated at all. The victim was cut by a killer while watching a movie in a movie theater. It's not complicated at all. A similar case happened in a movie theater a week ago, but the place was in the sightseeing elevator of the movie theater."

"Serial murder?"

"The surveillance videos of the two cases have not been compared yet, and this possibility cannot be ruled out." Inspector Xu did not dare to draw conclusions without sufficient evidence.

"If you need my assistance, please let me know." If it was before, Bai Haolin would have asked Sergeant Xu for information, but now he is more anxious to find the inner ghost of the police station and has no time to do so.

"Well, definitely." Through previous cooperation, Sergeant Xu was more convinced of Bai Haolin's criminal profile, but he didn't want to seek help from others so early.
