crime profiler in the dark

Some lonely people prefer midnight movies, especially those that don’t sell well, not because they like to watch unpopular movies, but because they like to see only one person in an empty movie theater, which makes him feel special , Xiao Li is one of them.

Xiao Li is 22 years old this year. He has just graduated from school and found a clerical job. As a newcomer to the company, he mainly does small things such as serving tea and copying materials every day, which makes him feel very uncomfortable , because of his introverted personality, he doesn't have any friends to talk about his unhappiness, and he doesn't want to worry his parents in other places, so he often sits in a daze alone in the movie theater at midnight, and today is no exception, but what makes him extremely unhappy is Besides him, there was a couple in the first row kissing me like no one else, and behind him was a single man like him. There were only four of them in the movie theater of Nuo Da.

Xiao Li stared at the screen, but his mind was not on the movie. He was thinking about what the boss looked at him during the meeting today, and what did he do wrong to make the boss unhappy?Xiao Li was so engrossed in his thoughts that he didn't realize that the man sitting behind him had quietly come up behind him, and covered his mouth with his left hand as quickly as lightning. Xiao Li panicked all of a sudden. The first thought in his mind was: "Robbery!", but before he took out his wallet and obediently handed it in, the other hand had already skillfully made a gap on his neck, before he even had time to feel the pain, I just watched the blood of the carotid artery spurt out, drawing arcs in the air and staining the seats in several rows in front, but the couple sitting in the first row didn't notice it at all, and were still immersed in it. In the world of two...

two hours later

Sergeant Xu from the Criminal Investigation Department of the Baihu Police Station came to the scene of the crime. At this time, Liu Jiajie, the forensic doctor on the night shift, had already done a preliminary autopsy and was asking the assistant police to pack the body and bring it back to the forensic department. Sergeant Xu stopped Liu Jiajie:

"Doctor Liu, what's the matter?"

"There was only one wound on the corpse, and the margins of the wound were smooth and tidy, in the shape of a spinneret. It can be judged that the murderer's knife was extremely sharp, and it may be a scalpel; the direction of the incision was from left to right, indicating that the murderer was right-handed; the cause of death was that the neck was severed. arteries, causing massive blood loss leading to death."

"Is it possible that the murderer has a medical background?" Sergeant Xu asked.

"It's possible, but I'm not sure." Liu Jiajie shook his head, expressing that he couldn't judge.

"Boss, I went to ask the box office. Four tickets were sold for this movie, one for the deceased, two for the couple who reported the crime, and one for the murderer." Police officer Wan Ming came to report the situation.

"Can the conductor recognize the murderer?"

"She said that except for the deceased, the other three bought tickets through self-service terminals, and she didn't see their faces."

"Tsk." Sergeant Xu felt that there were very few clues, which was quite tricky.

"Boss, I heard that Sergeant Zhu and his team also received a throat-slitting case last week, and the location was a Broadway theater." Wan Ming said, "Could the murderer be the same person?"

"Is it the same at the scene?" Sergeant Xu asked.
