Shut up wisely.

The door opened, and Xiao Min walked in with two appraisal certificates. She seemed to feel that the atmosphere in the room was a bit awkward, but she couldn't say it. She smiled and put down the appraisal certificate, "Doctor Su, this is Mr. Fang's wound reexamination.

The book and the identification certificate you asked me to print for you last time in the laboratory, I will go out first."

"What did you ask Xiao Min to print for you?"

"Huh?" Su Yawen looked up from the appraisal book and suddenly said, "After you left, I went to the crime scene again last night, resampled the blood remaining on the ground, and reanalyzed the blood that I had with Xiao Li at that time.

The brain toxins brought back from the corpses, etc., now seem to have made unexpected progress."

"How do you say it?" Fang Jun listened attentively and took the opportunity to change the topic of Alan.[

"I found that there was not just one kind of toxin in Xiao Li's blood, but a variety of toxins. Although the concentrations were different, I could clearly feel the different types and the different times of ingestion.

Therefore, it can be determined from one aspect that if Xiao Li's death was due to poisoning, the toxin seemed to spread slowly, and there should be signs some time before death, whether it was emotional or physical deterioration, and immunity decreased."

Fang Jun nodded, "When I got the task from the bureau that day, I talked to Xiao Li's good brother once. He told me that Xiao Li had met him once before he died. At that time, Xiao Li

His mood was very unstable and his face looked haggard. It seemed that if he had not lied to me, Xiao Li would have been poisoned at that time."

"And I identified a very strange toxin in the brain that was extracted from Xiao Li's brain. This substance contains a large amount of morphine and heroin. Did Xiao Li have a drug problem before?"

Fang Jun glared and denied, "No way! Xiao Li has always been very dedicated to his duties, and he has always had a good relationship with the people in the anti-drug brigade. How could he be taking drugs? Don't forget that he is a policeman!"

"That's weird," Su Yawen muttered while looking through the documents in his hand. "Since it's not drug abuse, where did such a large amount of morphine and heroin come from? Moreover, the drug itself has the function of controlling human nerves, so now it can't

Determine whether Xiao Li committed suicide or was killed by others."

It seems like things have gone back to the original mystery.

Fang Jun was puzzled by Su Yawen's complete denial of the initial reasoning, "Even if heroin and morphine were found in his brain, what does it matter? Does this deny the possibility of suicide?"

"It's not a denial, but it's not 100%," he is truly a 100% paranoid, not allowing the slightest doubt.

"Drugs can make people go crazy. According to my test report, there were at least four kinds of snake venom in Xiao Li's blood. It can be imagined that he was in extreme pain at the time. And if the drugs flooded the brain and the nerves were uncontrolled, suicide is not impossible.

.

Secondly, according to the evidence report provided by your bureau, no other person’s fingerprints were found on the knife edge except Xiao Li’s. Therefore, even if, as mentioned before, the wound is a sign of homicide, poisoning first and then killing, etc., it cannot be 100% certain.

I am absolutely certain that Xiao Li committed suicide."
