"Makiyuki, tell me about cathinone." I put down my phone and looked at Han Muzhi eagerly, he had studied pharmacology and must know.

"Cassione, which is extracted from a plant called khat grass, also known as qiaocha, is a new type of drug." Han Muzhi frowned, "Are you still in charge of He Xiaomin's case?" I said, that's the police—"

"There's no way I can't leave it alone." I sighed and interrupted Han Muzhi, "I can't accept that Xiao Min committed suicide, that made me carry a cross in my heart." Makiyuki, you know me, I can't memorize another one. ”

Han Muzhi was silent, and said after a long time: "Pay attention to your own safety." Rest early, I'll have a meeting tomorrow, so let's go first. Call me for something. After a few more words with Yingying, he left.

I'm a little lost, Han Muzhi has always cared for and protected me meticulously, this time my stubbornness, I'm afraid that it will hurt him.

I arrived at Yiqiao early the next morning, and it wasn't until about ten o'clock in the morning that Yang Yize hurried over, and I invited him to the reception room. "Officer Yang, what the hell is going on?" I asked eagerly.

"Yesterday, we urgently asked the forensic doctor to do an autopsy, and the results came out, but it will take some time before the official report is issued to the family, so Xiaomin's mother doesn't know the situation yet, I will tell you in advance." Yang Yize said, "He Xiaomin has a residue of cathin-ketone in his stomach, cathin-ketone, does Mr. Xin understand?" ”

I nodded: "I heard Dr. Han say that it is an extract of khat grass." "I don't know anything about drugs.

"Yes," Yang Yize nodded, "Khat grass is a new type of drug in recent years, and it has been listed as the target of our crackdown in the past few years. Long-term or excessive consumption can be addictive, and can also lead to anxiety, insomnia, hallucinations, etc., and in severe cases, myocardial infarction. ”

"Could it be that Xiao Min fell downstairs after taking too much Khat grass and hallucinating?" I made an inference.

Yang Yize shook his head slightly: "According to Xiaomin's death time and the decomposition speed of cathin-ketone, the forensic doctor judged that this dosage would not cause hallucinations, and if it really produced hallucinations, according to common sense, how could there be a seizure process, whether it was dancing or crazy, how could he run directly to jump off the building?" ”

"That is to say, the cause of Xiaomin's death is still the conclusion that he committed suicide?" My whole body is a little cold.

"Judging by the current evidence, it is." Yang Yize scratched his head in annoyance, "I have told the white team several times that this case is definitely not that simple, if you want to commit suicide, you can commit suicide, why do you still take drugs." There must be something strange, the white team decided to investigate again, but a task force came from above to mobilize police forces to investigate another serial murder case, and this case could only be put aside. It's sad. ”

"By the way, when Xiao Min jumped off the building, her mother and neighbors were present, did you see Xiao Min's other abnormal behaviors?" I was not reconciled, "You should have asked about the investigation before, right?" ”

"That's for sure." Yang Yize replied, "The first thing we asked was the witnesses, but at that time, Xiao Min's mother had her back to Xiao Min and didn't see anything, and the neighbor said that she saw Xiao Min painting at the table, and then suddenly stood up, walked to the window and jumped down, without any unusual behavior." ”

"Did Xiao Min go out in the morning, or did he see anyone the night before?" I asked.
