crime profiler in the dark

After returning from the Lanshan Psychiatric Hospital, Yi Yunzhao immediately called out the report on the throat-slitting case that had just been closed.

There were four victims in the serial throat-cutting case, the first two were killed in a movie theater, No.3 was killed on a bench in Baihu Park, and the fourth was killed in an underground parking lot of a commercial building.The murderer was cautious at the beginning, even in a public place like a movie theater, he did not leave any clues.

But starting from the third case, the criminal pattern of the murderer became disordered, and Zhuang Xuzhuo of the Psychological Support Department judged that he was taking psychotropic drugs. Prescription drugs for depression, prescription drugs have strict prescription standards, so the suspect was traced to find out, but he committed suicide by jumping off the building when the police went to arrest him, but the clothes at the time of the crime were found in his home, and the evidence is solid.

But is it so?Before asking Nurse Huang, Yi Yunzhao might agree with the results of this report, but now he has doubts.

Yi Yunzhao closed the report and was going to find out the details of the case from Chief Zhu and Chief Xu of the Criminal Investigation Division who were in charge of the case at the time. Go find Bai Haolin.

As soon as I reached the fourth floor, I met Qin Siye: "Yun Zhao, are you looking for Hao Lin?"

"Well," Yi Yunzhao nodded, "By the way, I remember that the No.3 victim in the throat-cutting case was the autopsy done by you."

"The one whose throat was cut in Baihu Park? It's me, what's wrong?" Qin Siye didn't know why he suddenly mentioned this, "Isn't this case closed?"

"I saw in your report that the murderer has a certain degree of medical knowledge, but what level of medical knowledge does he need to know how deep the throat can be cut to allow blood to flow back into the trachea?" Yi Yunzhao asked.

"At least a sophomore at a medical university." Qin Siye thought for a while and said.

Yi Yunzhao remembered that the murderer was studying economics at university: "What if I taught myself? Or are my parents doctors and nurses?"

"Please! Is there any textbook that will teach you the angle and depth of cutting your throat?" Qin Siye said angrily, "Even if there are doctors and nurses at home, it is impossible to talk about this kind of thing at the dinner table, right?"

Yi Yunzhao felt that what Qin Siye said made sense. After all, it is impossible to learn something like murder without a teacher. Could it be that the suspect was really possessed by something unclean while he was in the mental hospital?

Seeing Yi Yunzhao's strange expression, Qin Siye worried that he was thinking wrong again, and said, "Yunzhao, why are you suddenly interested in this case?"

"When Doctor Bai and I went to the Lanshan Mental Hospital yesterday, we found out something." Yi Yunzhao told Qin Siye what they found out yesterday, "So I suspect that the murderer of the serial throat-cutting case may be someone else!"

"You mean that Zou Jun who framed him?" Qin Siye was a little surprised.

"Uh——, sort of." Yi Yunzhao swallowed back the words "possessed by an evil spirit".

"However, the police will not retry the closed case unless there is conclusive evidence. What are you going to do?" Qin Siye tilted his head and looked at Yi Yunzhao.

"The old way!" Yi Yunzhao often secretly investigates the cases he is interested in, which is already common.

"Hey, I knew the Yi Yunzhao I knew would not give up easily!" Qin Siye said with a smile, "Ann, I will still be your strong backing this time!"

Yi Yunzhao nodded, "I'm going to find Dr. Bai, and I want to ask him some questions."

"Haolin just went out. You can ask Zhuang Xumao, the new profiler. I remember that he was in charge of that case." Qin Siye suggested.

"Oh, thanks." Yi Yunzhao thanked him and left.

Because Bai Haolin's office is relatively small, Zhuang Xumao sat in a small cubicle in the big office area. When Yi Yunzhao left, he was chatting with a colleague:

"..., so I judge that the murderer must be engaged in blood-related work. Otherwise, he would not have taken out the victim's blood and replaced it with antiseptic."

"But maybe it's for better preservation of the corpse? Didn't you just say that the No. 1 victim was placed in the bridal shop for several days without being found?" Although the colleague was engaged in administrative work, he was very sensitive to reasoning. Interested, put forward different opinions.

"Yes, he put the corpse in public to attract attention, but the means and method of drawing blood are very professional, so I judged that he must be doing blood-related work, such as the staff of the blood donation center, the embalmer , doctors in the hematology department, etc." Zhuang Xusubaru said.

"But the scope is still very wide. Isn't it difficult for the Criminal Investigation Department?"

"The murderer is very cunning, there is no clue now." Zhuang Xumao sighed lightly.
