Back in the office, Xun Mu took out two bottles of Red Bull from the drawer, threw one bottle to Su Ping, and opened the ring by himself and poured the other bottle into his stomach.

"Xiong Yikun's death should have nothing to do with the gang behind it." Su Ping didn't drink it, put the can on the table, and said:

"Xu Qinghai is right about one thing, if they want to deal with Xiong Yikun, they can do it a long time ago, and they don't have to wait until he goes home and dismiss their subordinates. Moreover, they will never let go of Xu Qinghai and the three of them. ”

Xun Mu didn't answer, only turned his head to look out the window.

After looking at it twice, he said, "Lao Meng, they haven't come back yet." ”

"There are a lot of people, and of course it takes time to move." Su Ping took over: "Don't worry, there will be no accidents." ”

Xun Mu nodded lightly.

As early as 12 o'clock, they completed the surprise interrogation of Ah Cong and Wang Tsai, and obtained part of the list of the criminal gang, as well as the testimony of some high-level personnel.

Of course, because they were both drunk at that time, the testimony obtained could not be used as the basis for filing a case, and the suspicion of those people could not be determined, so Lao Meng led the team out, just to prevent the suspect from running away after receiving the news.

After obtaining Xu Qinghai's confession, the two verified the list and found that there were no discrepancies, and then ordered Lao Meng to let their people act immediately, detain or summon these suspects, and bring them all back.

After being silent for a while, Xun Mu asked again: "You say, if it wasn't for this gang, who would it be?" ”

"It's hard to say." Su Ping pouted: "This guy has done too many things that hurt the heavens and reason, and the enemy is gone, the question is only that apart from the gang, who can make him willing to die?" ”

"I don't think he's reluctant." Xun Mu shrugged: "There are no traces of resistance on the deceased's body, and there are no restraint injuries, which doesn't mean that he doesn't want to resist." ”

"Huh?" Su Ping was stunned for a moment and asked, "What do you mean?" ”

"Don't forget," Xun Mu said, "he died of a disulfiram-like reaction, which in simple terms, was to drink a lot of alcohol and be injected with cefoperazone at the same time.

So, is there such a possibility, he first got drunk in the study and was unconscious, and then the murderer slipped in, found him lying on the ground, and in a flash of inspiration, injected him with cefoperazone.

After all, it takes a long time for alcohol to metabolize, and even if he is drunk, there is still a large amount of alcohol accumulation in his body.

According to Lao Yan, the methiotetrazole substituent on cefoperazone will seriously affect the metabolic process, so that after alcohol is metabolized into acetaldehyde, it cannot be metabolized, resulting in acetaldehyde accumulation.

Acetaldehyde is much more toxic than ethanol, and after the ethanol in the deceased's body is converted into acetaldehyde, it eventually causes Xiong Yikun's death. ”

Su Ping pondered for a long time before finally shaking his head and saying, "Your brain is very open. But since Xiong Yikun is unconscious, why didn't the murderer just strangle him, but instead went to great lengths to get cefoperazone to inject him?

While it's not hard to buy — even though it's a prescription drug — the killer can't just happen to have cefoperazone with him when he comes to the door, right?

Besides, after continuous public welfare publicity in recent years, many people have indeed learned that cephalosporin cannot be taken with wine, otherwise it is equivalent to poison.

However, among the cephalosporins that most people understand, or recognize, the main ones should be cefradine, cefixime, cefaclor and other more common and commonly used oral drugs, right?

As far as I know, the above mentioned several cephalosporins do not cause a reaction when taken during drinking, but in order to avoid making it too complicated, the masses are confused, and it is not clear whether they can eat it.

Logically speaking, even if the murderer really has the kind of idea you said, he should make some oral capsules like this for Xiong Yikun to eat, right? ”

That is to say, it was Xun Mu who put forward this statement, if he was changed to Qi Yuan, Su Ping would definitely spray him in the face.

Xun Mu touched his chin: "I also know that this statement is a bit far-fetched, and there are many places that are far from the past." But if it weren't for Xiong Yikun, who was killed by a criminal gang, I could only think of this possibility at present. ”

Su Ping frowned.

If you think about it, that's true.

If you want to inject Xiong Yikun in his armpit without resistance, and inject cefoperazone into his body, you can either get his active cooperation, or take advantage of the fact that he has no sense of resistance when he is drunk.

To put it another way, the more difficult the conditions to achieve, the clearer the direction.

"If that's the case, it's likely that the killer was a medical worker, at least not just about medicine." Su Ping said: "Moreover, I should be quite impressed by the disulfiram reaction between cephalosporin and wine, otherwise I wouldn't think of cephalosporin when I saw Xiong Yikun drunk." ”

"Hmm." Xun Mu nodded lightly: "But there is one more problem." What was his purpose in doing this? ”

"Purpose?"

"Like you said, in the face of a man who has no power to resist, it is a good choice to directly cover up, strangle, and stab to death, there are no variables, why should he complicate simple things?

Cefoperazone is not difficult to get, but it takes time. What if he takes advantage of his departure to buy medicine and comes back, what if he wakes up?

Drunkenness is uncontrollable, one second you may sleep like a dead pig and you can't wake up, and the next you may suddenly jump up and shout that I can still drink - although this is rare. ”

"That's a problem, indeed." Su Ping bowed his head slightly, and then said: "But, after Xiong Yikun's death, didn't there be three people rummaging in the study?"

This shows that the murderer is likely to be committed by a gang, is it possible, after finding that Xiong Yikun was drunk, he left two people to watch him, and one person was left to buy medicine? ”

"And for the purpose of doing this?" Xun Mu questioned again: "Since he knows that cefoperazone can react with alcohol, and he knows more about medicine, then he shouldn't have thought that our forensic doctor can restore the cause of death of the deceased and detect the cephalosporin in the deceased's body." ”

"Hey, what's wrong with you?" Su Ping's eyes widened: "Isn't it your own speculation?" Why are you still questioning me? ”

Xun Mu scratched his head.

Su Ping rolled his eyes, and continued: "It's not that it can't be explained. Maybe he just wanted to die when the deceased was unconscious and had no resistance, creating an illusion that Xiong Yikun had to choose death because of the threat, so as to splash dirty water on the criminal gang and pick himself out.

Judging from the results, at the beginning, the criminal gang behind Xiong Yikun was indeed the object of our key suspicions, and we didn't think about anything else. ”

After a pause, he continued: "Or, he has already made a plan to kill people with cefoperazone and alcohol, and has been prepared for it. The reason why Xiong Yikun is drunk is that he poured it. ”
