Chapter 1834: Tetramine

At 3:00 p.m., in a KFC restaurant outside the high-speed rail station in Yaoming City.

"Don't worry, master." Wang Can looked at Zhao Yu who was munching on a hamburger, and assured him with a determined face, "I will continue to investigate according to your ideas, and I will definitely investigate all the relevant personnel in the prison!"

"Yes," Zhao Yu said, "according to the evidence we have so far, Nong Zhifa should have had no mental problems before he was imprisoned, so the most critical part of the murder memoir should be in the prison!

"Now that the staff have all screened, let's check the prisoners!"

"Yes!" Wang Can nodded.

"But..." Cui Lizhu took a sip of Coca-Cola and said with disbelief, "Nong Zhifa has been imprisoned for 14 years. It's a prison, and the prisoners are not like revolving doors. If we search one by one, we will find them." when?"

"Yes, I roughly counted them," Wang Can said, "There are nearly 5,000 prisoners who may have come into contact with Nong Zhifa!

"However, if you follow Master's elimination method, you should be able to narrow down the scope layer by layer.

"We will send more people and try our best to fight for it!"

"Also," Zhao Yu said again, "There may be other circumstances surrounding Nong Zhifa's hypnosis. Next, you can pay attention to the people who came to visit the prison these years ago, or the letters related to Nong Zhifa, etc. wait……

"Since the hypnotist is a master, it is also possible to hypnotize Nong Zhifa by other means!"

"Understood, I remember!" Wang Can nodded.

"Also," Zhao Yu simply put down the delicious hamburger, and instructed again, "I heard from Sister Wu that senior hypnotists are not common, you'd better send someone to investigate along this line of thought, and see if Yao Ming Are there any qualified hypnotists around here?

"What if this person came into contact with Nong Zhifa through other channels? For example, he can use the opportunity to provide psychological counseling to prisoners, or has any relationship with the prison, etc..."

"Yes!" Wang Can hurriedly took out his mobile phone and recorded Zhao Yu's instructions.

"Of course, Liu Cheng is also a key figure. Don't ignore this mental patient. After all, he is the only person who has seen the memoir killer!" Zhao Yu said again.

Wang Can nodded again.

"okay,

After explaining everything, Zhao Yu picked up the hamburger again and said, "If we still get nothing after all this tossing, it can only mean that my inference is wrong!"

"At that time, let's investigate again according to the original thinking!

"However, before you are 100% sure, don't let go of any information! The truth often appears somewhere inadvertently..."

"Well..." After Wang Can nodded, he said to Zhao Yu, "Master, you have to be careful, I heard that the case you are going to handle is not easy!"

"Okay, don't ask too much about our affairs, just complete your own tasks," Zhao Yu said after eating a few mouthfuls of hamburger, "If you have any latest news, remember to let me know!

"I've already called the Criminal Department. Although I'm not in charge of this case, I still retain the right to participate. So, just report to me, don't worry about leaks or permissions..."

"Yes yes yes!" Wang Can pointed to the front desk of the restaurant, "I see that you eat so deliciously, why don't you... order a few more hamburgers..."

...

Half an hour later, Zhao Yu and other special team members boarded the plane and sat in first-class seats.

"Boss, I still want to chat with you about something," Ran Tao, who was sitting next to him, suddenly said to Zhao Yu before the plane took off, "I have been to the prison where Nong Zhifa was imprisoned, and I have also been in-depth with the prison staff. contacted.

"They told me..." Ran Tao surveyed the environment, and then continued cryptically, "Actually, all the prisoners in the prison will have psychological problems to some extent, especially those who have committed serious crimes!

"So, Nong Zhifa has psychological problems, which is actually quite common.

"Think about it, if a person is sentenced to life imprisonment and loses his freedom, even if he can get by in prison, it's impossible not to have some negativity and negative emotions!"

"Hmm..." Zhao Yu listened carefully, recalling his past life in prison. Indeed, as Ran Tao said, as a prisoner, the chance of losing control of his emotions is naturally higher than that of ordinary people.

"They also told me that even if a prisoner has serious mental problems, as long as he is not violent or suicidal, the prison authorities are not very willing to report it!

"Because..." Ran Tao said in a low voice, "Once the prisoner's family finds out, they will definitely think that it was the prison's supervision error that caused the prisoner to lose control. Complaints or prosecutions will inevitably affect the prison. Of course not!

"So, regarding the issue of Nong Zhifa, I really can't say for sure. What is the reason?"

"Hmm..." Zhao Yu sighed, and said with a sense of enlightenment, "I can understand what you said... Maybe I'm too sensitive!

"Or maybe it's because I feel uncomfortable seeing Nong Zhifa, the murderous demon, dying in bed...

"Also, maybe it's because of my subjective wish that I still hope that a real murderer will appear so that he can be brought to justice...

"But..." Zhao Yu gritted his teeth and said, "For such a big case, we must maintain a skeptical attitude!

"Until the moment the evidence is conclusive, we must investigate every doubtful point before we can draw a final conclusion!

"So, we can't look at this case according to the usual way of thinking. After all, Nong Zhifa's character and trajectory are inconsistent with the memoir killer, and Liu Cheng has also confirmed that the case in the nursing home was not done by Nong Zhifa... ..."

"I understand..." Ran Tao realized, "It turns out that my worries are completely unnecessary. The boss has already seen this case clearly and thoroughly! It's amazing!"

"Hehe, I haven't heard Brother Tao flatter for a long time..." Zhao Yu made a joke, which caused the two of them to look at each other and laugh.

At this time, the flight attendant reminded the passengers that the plane is about to take off, please be prepared...

Unexpectedly, just as the plane was about to take off, Zeng Ke received a message, turned around hastily, handed the phone to Zhao Yu, and introduced to him at the same time:

"Team leader, the autopsy report from the Andu Police Station came out. The victim has been dead for three days. Because of the make-up, the corpse doesn't look very rotten...

"Also..." Zeng Ke pointed to a message on the phone and said, "The cause of death has also been investigated. The deceased was indeed poisoned and the poison was tetramethylene disulfone tetramine, which is what we often say. The—Tetramine!!”

"Wow!" Zhao Yu was speechless in surprise, "Tetramine? So...advanced!?"

"What's even more powerful is..."

Just as Zeng Ke was about to explain the situation, the beautiful stewardess in the distance suddenly quit, and shouted to Zeng Ke: "Sir, the plane is about to take off, please sit back and put away your phone..."

"Oh... oh..." Zeng Ke quickly turned around and sat down. At the same time, the plane started to start and entered the take-off state.
