Because the people in the USB flash drive are wearing masks, they need to be identified by professionals in the technical department.

I turned around and walked out of the alley, and when I went out, Brother Liao had already walked for several minutes, and Brother Liao and I had to be vigilant.

Brother Liao and I discussed using text messages to communicate so as not to cause more trouble, and if things go well, then the murderer will be tricked.

Back in the store, Zhao Mei stayed in bed as before, and there was no damage in the store.

If we can find those people in the USB flash drive tonight, it will be of great help to our work to solve the case.

This is the moment when the technical department races against the clock.

I suddenly remembered a very serious problem, since they had already poisoned Zhao Mei, the situation of the congratulatory letter was also very dangerous.

You have to quickly inform Brother Liao to send someone to protect the congratulatory letter, he is the only clue to this case, if something goes wrong, this case will definitely become an unsolved case.

To gain time, I sent a text message to Brother Liao, and when I saw that he didn't reply to me, I dialed his number again, and it rang for more than ten seconds before someone answered, but it was not Brother Liao but Wang Yu.

I told Wang Yu to ask Brother Liao to send someone to protect the congratulatory letter, and Wang Yu said that Brother Liao was busy with the affairs of the technical department and couldn't get out.

Wang Yu definitely won't be able to leave, so I asked Wang Yu to tell Brother Liao to come to the drug rehabilitation center to find me later.

I hung up the phone in a hurry, I was afraid that if I arrived a moment late, I would be the first to arrive.

I took a taxi to the drug rehabilitation center, and as soon as I got in the car, I asked the driver to drive faster, and the journey from 10 minutes was shortened to 5 minutes.

I got out of the car and paid the fee, so I hurriedly ran into the drug rehabilitation center, and as soon as I entered the gate, I saw Xiao Mu coming out, so I asked him about the congratulatory letter.

He told me that the congratulatory letter was transferred to another drug rehabilitation center at about 10 o'clock in the morning, and Xiao Mu and they confirmed it again and again, so they let him take it.

Xiao Mu also said that there were five people who took away the congratulatory letter, and two of the fat men were the most conspicuous.

I looked at the faces of the four people in the surveillance, and by the way, I took a few photos with my mobile phone.

There was also a person who was covered the whole time, and I don't know what he looked like.

When I left the drug rehabilitation center, I called Brother Liao and told him that the congratulatory letter had been diverted and a clue had been broken.

Another layer of coefficients has been added to the case.

Brother Liao said that he could only take one step at a time, and the technical department would not be able to produce results until later.

Brother Liao originally wanted me to wait, but when I thought of the limited time in the evening, I refused Brother Liao, and I asked him to talk to me tomorrow night.

I also told him about Su Chen's participation in solving the case, and I could let Su Chen look for clues together during the day.

Brother Liao did not object, but welcomed Su Chen in particular.

I really don't know what he's trying to do.

After talking to Brother Liao, I went home, nothing happened on the way, I hope something happens, because as long as someone does it, our next step is to go.

The moment I opened the door, a pungent smell came from me, and it was actually the smell of gas.

I quickly opened the door of the shop as much as possible to let all the gas out, I found the faucet, opened it to wet the corner of my clothes, covered my nose, and closed the valve of the leaking gas.

I didn't see Zhao Mei in the store, could it be that she sneaked away while I wasn't there.

What is the situation with this Zhao Mei?

Is it playing stupid?

I opened the window to let the gas out, and I waited in front of the store for fifteen minutes before the gas ran out.

I waited a few more minutes before I closed the door, closed the window, and lay down on my bed, if I hadn't had the foresight, my shop would have exploded.

I look back on what happened in the past two days, and after some sorting out by me, it seems that they have already done it, and the target is not me, but the congratulatory letter, which is a chess piece that is crazy about each other.

Now I can explain why Zhao Mei is pretending to be stupid, so that I think she is an innocent victim, so as to better lure me away, so that her accomplices can take away the congratulatory letter.

I wrote down the clues I knew in my notebook, so that Su Chen could better understand the entire case and keep up with Brother Liao.

If you don't prepare in advance, the murderer won't be fooled.

They will be disguised, don't we?

They picked up an addict and a prisoner who was about to be shot, so they would hang it horizontally and vertically, let them kill, and they could be charged with killing innocent lives.

The congratulatory letter is the only clue, and if it is simply left in the drug rehabilitation center, it will be a loss of face for the criminal investigation.

The congratulatory letter is still in the drug rehabilitation center, but in the quarantine area, because only by sending them to quarantine will they not succeed.

So they have a plan, we have a strategy, and as long as they realize that they have been deceived, we will be able to catch them.

Although they took the congratulatory letter away at 10 o'clock in the morning, they must not have realized the identity of the congratulatory letter, because the fake congratulatory letter is in the process of drug rehabilitation, and it will have seizures from time to time.

If they want better information, they will definitely give fake congratulatory letters.

We told this fake congratulatory letter that as long as we cooperate with the work, we can reduce the penal code for him, but he will not have the freedom to stay in prison and be converted from the death penalty to life imprisonment.

We didn't tell him explicitly, and if he knew that it was a life sentence, he would definitely not have done anything with his heart, and maybe it could have done something bad.

So it's better to keep an eye on it than anything else, and we've done it to prevent accidents.

Now just wait for the prey to emerge, and all the capture work is already ready.

Because it was ten o'clock in the morning, it had been arranged for nearly thirteen hours.

However, the location of the murderer has not always been determined, so they are still waiting for the opportunity, as long as they return to the lair, the arrest work will be launched, and the people of the Criminal Investigation Bureau will rush to the lair as soon as possible and take it to the pot.

In the places where they left, Brother Liao sent people to check.

No major clues were found, so we had to wait until their positions stopped moving before we had a better chance of winning.

9 a.m. on the sixth day......

I am Su Chen at the moment, and Su Chen has read all the clues I wrote last night, so I have no objection to this.

Brother Liao drove to pick me up, and he had already called to inform me before.

So, I followed Brother Liao to catch the murderer.

At 8:50, it was the third time to confirm the location information, and when they saw that it was the murderer's nest, Brother Liao and Wang Yu couldn't wait.

The murderer's nest is in a small town called Xiumo, about two hours' drive from the Criminal Investigation Bureau.

After all, this is a cross-provincial case, and the police station in Xiumo Town had to be notified.

Let them work together to solve the case, and when they go, the handover has already been completed, and the police station in Xiumo Town is also watching, and they will not let the suspect escape the law.

Although it is a police station with only a dozen people, I heard that the ability to handle cases is quite high.

Two hours later, they arrived at the Xiumo Town Police Station, discussed with the chief, and carried out the arrest operation ten minutes later.
