Jiang Bai, who returned to the bedroom, analyzed the surveillance video by Du Yiheng this time, and at the same time he also took out the kitchen video that had not yet been returned.

"I'll go, and there are people like that?"

He Dazhuang was surprised when he saw a man who was tightly wrapped in his whole body sneaking into the back kitchen, "Is it just for stealing food?" ”

"Don't be funny, that shop is famous for charity."

Du Yiheng said, "Every day, if there is anything left that cannot be sold, we will either let the clerk take it back, or give it to some students who may be in difficulty." Is it necessary to steal? ”

It was only after he met Yan Xiyue that he slowly learned about that store.

This is called "charity" in these years!

"So this is the murderer?"

He Dazhuang said, "It's wrapped so tightly on such a hot day, won't it die of heat?" ”

"What if he put it on temporarily? I suspect that the killer prepared his clothes in advance and only wrapped them up in front of the back door. ”

Jiang Bai said, "Du Yiheng, can you make the pictures on both sides come out at the same time?" ”

"No problem."

Du Yiheng said, instantly putting all the pictures on the same screen, although it is a little small, but all the pictures are in a clear state.

At the same time as the murderer appeared, what changes occurred in other pictures were what Jiang Bai was most concerned about.

Hard work pays off.

By playing back and forth to confirm, they found the man.

The first time he committed the crime, he went out of the store, and it didn't take long for the surveillance in the back kitchen to be able to see the murderer.

And according to the empty time in the middle, it is basically the time when he goes out and arrives at the back door!

The second time, too.

The third time something went wrong, he took a big bag and left.

"What's in that bag?"

Jiang Bai asked, "Can you improve the clarity?" ”

"You don't have to worry about me!"

Du Yiheng said, quickly operate the mouse and keyboard, after all kinds of codes flashed, the appearance of the big bag was instantly clear!

There was also a scarf used by the murderer for the same type of package inside!

"The evidence is conclusive."

Jiang Bai said.

The person who was caught by them in the surveillance happened to be Zhao Yiming!

At the same time, all the conditions known to Jiang Bai are met.

He is the first murderer who actually operated after getting the poison, that is, the murderer who actually operated.

The next thing is to find the murderer behind the scenes!

Jiang Bai knew that Zhao Yiming and Yan Xiyue had no relatives, no reason and no enmity, and there was no motive at all.

Collect money?

Zhao Yiming is actually a very hidden son, and it is impossible to do illegal things because of money.

Boss Li Changchun also treats everyone equally, and there is no such thing as partiality leading to jealousy.

And after Du Yiheng's search, Zhao Yiming is an information professional, and he is engaged in computers at most.

It is unlikely that it will have anything to do with the chemical engineering major or even the seniors who are so much older.

Therefore, he believes that there is also a mastermind in the middle who connects these two people!

Who can "drive" both at the same time?

At the same time, Liu Zifeng also found the clue!

After a night of unremitting efforts, he also saw the clues of the institute's video.

Liu Zifeng felt that maybe the inner ghost was Zhang Jiawei, who used to be from the same university as Jiang Bai.

So he observed Zhang Jiawei more in the surveillance.

Sure enough, he found the problem.

In one surveillance, Zhang Jiawei's direction was obviously towards the warehouse where the drugs were stored, and he even saw it from multiple angles.

But when he arrived at the warehouse where the medicines were stored, the surveillance around him did not see him.

After he left, the surveillance suddenly showed that there was one less Zhen!

There were also a few more people in the meantime.

They came out with the corresponding medicines, stored them in sealed jars, and brought them to some laboratories.

There are traces of this.

Even their rank is unaware that there is monitoring in the warehouse. Therefore, it is even more impossible to change the monitoring.

It's just Zhang Jiawei, he didn't take anything.

Neither going in nor coming out was recorded.

So he immediately called Jiang Bai.

"Zhang Jiawei's clue has been found"

Liu Zifeng said with some excitement.

"It just so happens that I have some clues here, too."

Jiang Bai said, "The murderer can basically be determined." ”

"Okay, then I'll pick you up and bring the murderer by the way?"

Liu Zifeng said that he was getting more and more excited, and the case was about to be solved!

"Well, the murderer is basically confirmed to be Zhao Yiming."

Jiang Bai said, "We have enough evidence in our hands. ”

It didn't take long for Liu Zifeng to come to the school, and after informing his boss Li Changchun, he took Zhao Yiming to the criminal police team.

Come to the criminal police team.

Jiang Bai handed over the evidence from his side to Liu Zifeng, and Liu Zifeng also communicated his findings with Jiang Bai.

"There's one person left in between."

Jiang Bai said.

"Well, look for someone who can connect them together."

Liu Zifeng nodded, "These two people can't be related, there must be someone who connects them, and this person is the mastermind!" ”

But for now, we have to start with the interrogation of these two people.

Liu Zifeng had already informed Sun Li that there was still some time for Zhang Jiawei to arrive, so he interrogated Zhao Yiming first.

"Zhao Yiming, do you know why I suddenly called you over?"

Liu Zifeng asked in the interrogation room.

"It's not going to be a bonus, is it?"

Zhao Yiming pretended to be very excited, and looked like he was completely open-eyed.

If you don't know his family background, you may really be fooled.

"The reward has indeed arrived."

Liu Zifeng said, "Your exclusive silver bracelet and small bungalow have arrived. ”

"What...... What do you mean? ”

Zhao Yiming still pretended not to know.

"There is already evidence that you are the murderer."

Liu Zifeng didn't talk much nonsense, and went directly to the evidence, "You should be familiar with these pictures, right?" ”

"This ...... How can there be monitoring in the back kitchen? When was it installed? ”

Zhao Yiming was a little flustered, but his acting skills were still online, "I don't know who the person in front of me is." ”

"And this scarf, how do you explain it?"

Liu Zifeng said, releasing the last time, Zhao Yiming ran out with a big bag.

The half-exposed scarf is exactly the outermost piece wrapped by the murderer!

"How...... How can it be so clear? It's fake. ”

Zhao Yiming was still quibbling, "I didn't bring these things at all!" ”

"This evidence is enough to prove that you are poisoning, you must know that this is a very serious crime!"

Liu Zifeng said, "If you do it all, then one charge of endangering public safety can ruin all your future!" ”

"Impossible! I studied a little bit of law, and my uncle said that you have to have objective consequences to be able to convict! ”

At this time, Zhao Yiming's "personality" has been lost.

"Then you know that poisoning is a kind of endangering public safety by dangerous means, and if it is poisoning, even if you have no consequences, it will be done by default!"

Liu Zifeng said, "I hope you can learn this knowledge well in prison in the future." ”

"I ......"

Zhao Yiming was very hesitant.

I don't know what I'm still thinking.

"I did it all by myself!"

Zhao Yiming said suddenly!

He said the answer that Liu Zifeng didn't want to hear the most!
