Regarding the death of the fourth victim, Ye Qing, it still deeply shocked the police and caught them off guard!

People didn't expect that the murderer of the rapid homicide would kill another pharmaceutical factory employee in such a short period of time!

According to reports from the scene, Ye Qing, who is now the director of the R&D department of the pharmaceutical company, died in his private car.

Although the autopsy report has not yet been released, it is inferred from the scene that he should have died of car exhaust poisoning! Someone used a hose to connect the exhaust pipe to the trunk and then started the engine, causing the deceased to be poisoned.

Since no signs of struggle were found at the scene, the police speculated that there were two possibilities, first, that the deceased died by suicide. Second, the deceased was murdered and was drugged into a coma before being poisoned.

Of course, because of the existence of rapid homicide cases and the special identity of the deceased, the police are naturally more inclined to the possibility of murder!

After the news came, Zhao Yu was also surprised. Unexpectedly, they have tried their best, but they still haven't stopped the murderer from committing murder!

At the same time, Zhao Yu was even more sure of one thing, the murderer must have accomplices!

Because, at first glance, it seems that Ye Qing's death is reasonable. But if you think about it carefully, you can find that it is not a simple matter to kill a person in this way.

First of all, if Ye Qing personally drove to the scene of the crime, then the murderer needed a good reason to lure him here.

However, now that the rapid homicide case is boiling, Ye Qing, as a party, has no reason not to care about his own safety, how can he be easily deceived?

Of course, there is another possibility, that is, the murderer stunned Ye Qing in advance, and then drove Ye Qing's private car to transport him to the woods and killed him.

However, if this is the case, the murderer must consider a question, whether he can avoid the surveillance probes on the highway and not be discovered by others?

All in all, if you want to successfully use this method to kill Ye Qing, you need to make a lot of preparations in advance, and Liu Yu's words alone don't seem to make a lot of sense.

After the incident, Li Luoyun was also panicked, and he hurriedly dispatched a large number of people to investigate the fourth murder case, wanting to find clues from it as soon as possible.

At the same time, he did not hesitate to arrange all the people on the new drug list to the Jinping Police Station and protect them from recurring.

Of course, there is another tricky thing that he urgently needs to prepare. Now that the fourth victim has appeared, it is highly likely that the murderer will contact the board of directors of the pharmaceutical company again and propose his new conditions!

Therefore, the police must control everything in advance and find a way to find Liu Yu.

At first, Zhao Yu was also a little strange, he thought that when those people on the new drug list were interrogated by the police, they would be able to know the truth about Liu Yu at the beginning!

But after a round of interrogation, nothing was found, and these people still insisted that they didn't know anything.

Later, Zhao Yu gradually figured out that perhaps, these people were not deliberately concealed, but really did not know.

The reason is also very simple, if you screen the remaining people on the list, you will find that these people are just ordinary R&D personnel of the new drug research team, no matter whether Liu Yu is fired from the pharmaceutical company or not, as long as the new drug is successfully developed, they will definitely have their credit.

However, for the four deceased, the situation was not ordinary.

First of all, the first Peng Ankang was a student of Liu Yu and belonged to the master-apprentice relationship. It is said that Liu Yu's information about reselling drugs was reported by him. The student betrayed the teacher, no matter whether Liu Yu was wronged or not, he would inevitably hate this Peng Ankang.

The second deceased, Lu Xiaohong, was just a general pharmacist who had just come to the R&D department for less than a year, and it stands to reason that her name could not appear on the list of new drug R&D;

Looking at the third deceased, Zhang Kaibin, he was not in Liu Yu's R&D group before, but not only did his name appear on the final R&D list, but he was also transferred to the quality inspection department as an official!

As for the fourth deceased, Ye Qing, not to mention, after Liu Yu left, he directly corrected it, and he was obviously the biggest beneficiary.

The situation of these four people is clearly not normal. Perhaps, it was these people who jointly framed Liu Yu, so Liu Yu was the first to attack them!

"Team leader!" Wu Xiumin immediately shrugged his shoulders after listening to Zhao Yu's analysis and said, "If it is really as you guessed, it means that Liu Yu has already taken revenge and will not kill the other people on the list, right?"

"Not necessarily!" Zhao Yu frowned and expressed his worries, "I feel that if someone really frames Liu Yu, there may be more advanced people involved! With just a group of people from the R&D department, I'm afraid it will be difficult to bring Liu Yu down!"

"Makes sense!" Ran Tao scratched his head and said, "If you want me to see, we have to screen the leaders of the pharmaceutical factory to see who has a holiday with Liu Yu? If we can find this person, maybe we can find the truth!"

"That's right!" Zhao Yu nodded, "I'll leave this matter to you! I know that there are many leaders in the pharmaceutical factory, so you go and ask Li Luoyun to ask for someone!"

"Okay!" Ran Tao nodded, turned and left the office.

"Team leader, the situation is not good!" Wu Xiumin also said very worriedly, "If there are also factory leaders among the people who framed Liu Yu, then next, will Liu Yu choose them to take revenge? In other words, the rapid killing will continue?"

"It's too likely!" Zeng Ke said, "From Peng Ankang to Ye Qing, the deceased is older than the other, and the murderer is also killing people in order from small to large! Next time, if there is another factory leader, it seems very possible!"

"God forbid, don't die anymore! If we die again, our special investigator career will be GAMEOVER!" Wu Xiumin clasped his hands together and kept praying.

"However, four ......people have already died," Zhao Yu pondered, "I think, if there is really such a factory leader, he should have realized that he will be Liu Yu's next target, right?"

"Hmph, I'm not optimistic about that dead guy," Wu Xiumin complained, "Just because I look like Guo Fucheng, I pick up girls everywhere, and it's annoying to watch!"

"However, I think Brother Tao is quite reliable!" Zeng Ke gave a contradictory opinion, "After all, Liu Yu was found out by him first!"

"Hmph, the blind cat just ran into a dead mouse, and there is no technical content!" Wu Xiumin was still disdainful, "If you are really capable, you can find out Liu Yu now?"

Liu Yu!?

In a word, Zhao Yu was reminded.

That's right?

Now all the problems are focused on Liu Yu, if this person can be found, then wouldn't the truth of the rapid murder case be revealed?

But...... This Liu Yu has already hidden his whereabouts, where else can he go to find it?

Ay?

That's right!

Suddenly, Zhao Yu remembered the female snitch Cui Lizhu. He remembered that when Cui Lizhu saw Liu Yu's photo, he was inadvertently stunned.

Don't...... Does she really know Liu Yu?

Otherwise......

Who knows, as if there was some telepathy in the dark, just when Zhao Yu just thought of Cui Lizhu, someone suddenly knocked on the door outside the office.

A small police officer ran over to report to Zhao Yu, saying that the woman he arrested wanted to see him, and also said that there was something important - to discuss!
