Ningtai County's Anti-Narcotics Squadron is under the name of the County Anti-Narcotics Committee, and its daily focus is on publicity, education, and communication to popularize the law.

Occasionally when encountering some drug cases, the anti-drug squadron often turns to the anti-drug brigade of Qinghe City for help.

In fact, the anti-drug brigade in Qinghe City does not have much business, but they have to support various districts and counties, and they are relatively independent brigade establishments, so they can show their presence from time to time.

The anti-narcotics squadron in Ningtai County is more theoretical. Zhang Kun, the squadron leader of the anti-narcotics squadron, came over directly with a laptop in his mouth.

meeting room.

After a brief introduction to each other, Zhang Kun put down his laptop and said: "From my understanding, this case should be a typical drug transportation case where people and goods are separated. This is the main form of domestic drug transportation at present. There are many specific methods. For example, the most common one is to use long-distance or short-distance buses to transport and carry drugs in the form of ant moving. Because the luggage carried in buses is not labeled, so even if we find drugs, even The person transporting the drugs was on the bus, and because he could not correspond to a specific person, it was impossible to identify and arrest the suspect."

Jiang Yuan, Liu Jinghui, and a group of police officers from Jiang Yuan's backlog case team all listened carefully to Zhang Kun's introduction.

Police work is also divided into different professions. The daily work of criminal police officers is different from that of public security, anti-narcotics or traffic police, etc. If you just do it briefly and participate in it, of course there won't be a big problem. Just be a human being, but most of the time it's something like solving a case that goes deep.

Zhang Kun was encouraged to see such a group of people listening so seriously, and continued: "In addition to using passenger cars for transportation, it is also a common method to borrow express delivery companies that do not have strict management. In some places, private cars are also used at night. Sometimes, you would stick the drugs on the chassis of a private car or something like that, and then secretly take them back when you park the car the next day..."

Zhang Kun talked about several ways to separate people and goods, which was an eye-opener for the police officers present.

Liu Jinghui also frowned: "I didn't expect that drug trafficking in my impression was still in the stage of motorcycle smuggling or pregnant women packing bags, but it would develop so fast."

Zhang Kun nodded heavily: "The separation of people and goods is spreading very quickly. Now there is a high incidence of unowned drug cases, and everyone has a headache."

Unowned drug cases refer to cases where only the drugs are found but the owner cannot be found. Although the cargo owner still has to lose a huge amount of money, compared with criminal liability, the punishment for lost cargo is too small.

Liu Jinghui rubbed his chin and pondered.

In just a minute or two, Liu Jinghui said: "Now to make a conclusion, if this case involves drug trafficking, then there is the most direct question, where are the drugs? Are they hidden or have they been transported?

Without waiting for anyone to answer, Liu Jinghui said to himself: "Just as Captain Zhang said, you can first check the information of the bus station and express station based on the identities of No. 1 and No. 2 to see if they have bought tickets recently. .!

This idea is very realistic. Although it sounds troublesome, it is still relatively easy to implement. It is nothing more than sending a few more police officers to verify.

Jiang Yuan agreed: "If it can be confirmed that a certain suspect is the owner of the cargo, the motive of this case will be easy to analyze."

"That's the truth." Liu Jinghui felt that the thick fog had been lifted halfway, and he breathed out happily.

Zhang Kun continues to popularize anti-drug knowledge to everyone.

After the meeting ended, the staff of Jiangyuan's backlog team dispersed, and with the new knowledge they had just acquired, they carefully checked the county's passenger transportation center and express delivery outlets.

Identity card, mobile phone number and other information were all found in vain.

If this was an ordinary case, or even an ordinary drug trafficking case, when it reached this level, it would probably be shelved.

Without clues, it is impossible to keep the members of the task force waiting.

However, Jiang Yuan's manpower for the backlog of cases is a bit too sufficient. Coupled with the continuation of the murder case, Jiang Yuan has a lot of manpower at his disposal.

"Check the surveillance, just check the surveillance at the bus station and express delivery point to see if we can find victims No. 1 and 2."

sit

At one end of the conference table, Jiang Yuan worked hard and came up with a stupid idea.

Liu Jinghui was startled when he heard this and said hurriedly: "This range is too big."

There are so many towns under Ningtai County, and most of them still rely on buses for commuting. The bus station is also quite large, with more than twenty buses and minibuses parked there every day, and the total number of surveillance cameras covering these vehicles and the waiting hall is well over a hundred.

Liu Jinghui was a little afraid to think about how long it would take to watch so many video surveillances. As for the express delivery points, there are quite a few of them. Each one is monitored and searched, which is at least the size of a bus station.

The key is that the monitoring system in places like bus stations is generally imperfect. People who often take buses may not even go to the station to buy tickets, but will wait on the street outside the station.

In other words, even if you check hundreds of surveillance cameras, you may still miss something.

Liu Jinghui would not do this kind of investigation plan. He has never fought such a complicated battle in his life. Speaking of it, the most complicated investigation he has ever encountered in his life was the time when he disappeared.

Jiang Yuan became famous at a young age, and he is from Jiangcun, but he is not afraid of waste. Anyway, there is only one clue, so let’s talk if we can’t find it.

The police officers below were not verbose. Once they got the order, they followed it.

Soon, the fourth floor of the newly built small building of the Ningtai County Criminal Police Brigade was filled with TVs and monitors.

More than two dozen police officers stayed up late to watch the surveillance camera for two days.

This scene made Zhang Kun, who came to help, dumbfounded.

Zhang Kun has been doing science popularization all year round and has few opportunities to participate in cases, and his participation in major and important cases is even lower. Jiang Yuan is now doing drug transportation cases on the scale of current murder cases. For Zhang Kun, it just feels like an explosion of abundant resources.

Jiang Yuan doesn't care what Zhang Kun thinks. For him, the drug transportation case that has not yet been determined is itself one of the components of the murder case. If no evidence of the drug case can be found, then the murderer's motive, the murderer and the victim It is difficult to explain clearly the relationship between people.

Jiang Yuan himself also scanned the surveillance screen, especially the ones that were particularly blurry.

On several occasions, several figures of similar stature were confirmed and eliminated through Jiang Yuan's image enhancement.

Time passed by minute by minute.

The policemen who were the first to participate in the task force's investigation of the case couldn't stand it any longer and began to fall asleep one after another.

Jiang Yuan transferred more police officers to fill the vacancies.

Mu Zhiyang also went into battle, found an empty seat, sat on it, turned on the computer and started reading.

After a while, Mu Zhiyang raised his hand: "Captain Jiang, I saw a person who looks a bit like victim number one."
