Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Wang Song's suggestion is to check online shopping records and try to find the person through the characteristics of the other person's clothing, or to identify the suspect.

Song Mingguang's suggestion was to investigate bank insiders.

The timing of the robbers' attack coincided with the sudden large amount of cash deposited in three branches of Binzhou Commercial Bank.

There is the question of whether someone is informing.

Of course, logically speaking, the two people from the coal mining company who deposited cash in the bank are also suspects.

So we can’t let this one go.

"Lu Chuan, what do you think?"

Unknowingly, Li Donglin had developed the habit of asking Lu Chuan for his opinion during meetings.

This is brought about by the experience of solving crimes in the past.

Lu Chuan can often give some special revelations.

Moreover, in this bank robbery, Lu Chuan discovered how two of the robbers escaped from the scene.

This was originally the most troublesome problem for the BZ City Criminal Investigation Detachment. After all, if they didn't even know how the robbers escaped from the scene, how could they track them?

Lu Chuan shook his head: "I don't have a mature idea yet. I want to do a spot survey of the things I retrieved first to see if I can make any discoveries."

Lu Chuan conducted more detailed on-site surveys on the roof of Cui's house and under the sewage well.

Some clues were also obtained.

But there is no time to analyze it yet. After the meeting, Lu Chuan will definitely not be able to rest. He will analyze these clues overnight to see if he can find some pointing clues.

"Okay, if you don't have any objections, the meeting will end here. Wang Song and Song Mingguang please work hard to get the investigation results as soon as possible."

Li Donglin looked at Gao Xiang again: "Detachment Gao, you guys from the BZ City Criminal Investigation Detachment must cooperate. After all, the serious crime team has limited manpower, and you are more familiar with the situation on your territory."

"Don't worry, Li Chu, we will do our best to support you!"

Gao Qiang also knew very well that when the crime squad came, Li Donglin had the final say in everything. He would just provide support and do whatever others asked him to do.

Although Binzhou's field exploration laboratory cannot keep up with Shanghai City's, it is still adequate.

General verification analysis can be done.

Lu Chuan and Wang Hao, the current detective here, are also old acquaintances.

We have cooperated many times before when solving crimes.

"Lu Jun, I'm going to trouble you again this time."

To be honest, Wang Hao was a little bit withdrawn. The Binzhou Criminal Investigation Detachment was sorry. It was less than a year and it seemed that Lu Chuan had been asked to help with three cases.

Lu Chuan smiled: "Anyone who has trouble is a colleague. Speaking of helping, I'm going to have to work hard for you tonight."

Nothing happened to Wang Hao.

After all, at that time, the BZ City Administrative Detachment didn't even know how the three endings were leaving, let alone finding any physical evidence related to them.

But when Lu Chuan took action, there was a lot of relevant physical evidence.

First there are four cash boxes.

"You collect the fingerprints on it and I will analyze them."

Lu Chuan hoped that the other party would leave fingerprints on the cash box when transferring cash.

Although this possibility is very small, it is still possible after all.

Lu Chuan must do this comparative analysis.

There are many people who come into contact with the cash box, including bank staff and security personnel, but in comparison, the number of people who come into contact with it is relatively fixed.

The cash box in the deposit car is for use with the vehicle.

When the payment vehicle arrives at the destination, the cash box will be opened, the cash inside will be taken out, and the cash box will be returned to the payment vehicle.

In other words, logically speaking, the only people who have access to the cash box are the staff of the three branches, the escort and the staff of the treasury.

And these people must have had their fingerprints recorded during identity collection.

As long as Lu Chuan could find fingerprints that were different from these people's, he would have reason to judge that there was something wrong.

In addition, Lu Chuan also discovered some interesting things on the roof of Cui's house. The robber on the roof must have changed his clothes after the police left. In this process, it was inevitable that his body parts would be exposed to the air.

In this process, even if the other party was very careful, it still left a big flaw in the other party.

A hair!
A short hair only one centimeter long.

Now, this is the most valuable clue Lu Chuan got.

Of course, Lu Chuan has not yet conducted identification and analysis on the hair, and it is possible that this hair belongs to the Cui family.

However, this possibility is unlikely.

There were only traces of the robbers lying and walking on the roof of Cui's house, and there were no other traces.

This shows that no one in the Cui family has been on the roof in a short period of time.

There is a high possibility that this guy with short hair is a robber.

While Lu Chuan was busy analyzing the evidence, Wang Song and Song Mingguang were also working intensively on their side.

Compared with Song Mingguang's case, which had specific investigators and targets, Wang Song's work was very difficult to carry out.

If you search for explosion-proof clothing online, you will find a lot of sellers.

More than a dozen people are holding computers and reading.

"Everyone, please be careful and be sure to find clothes that are exactly the same as those worn by the robbers."

Fortunately, there is one thing that makes everyone happy.

Although there are many prices for selling explosion-proof clothing on the Internet, the types of items vary.

The explosion-proof suits purchased by the three robbers are fully armed explosion-proof suits that cover the fingers from head to toe. This kind of explosion-proof suit is rare online and is generally relatively expensive.

So everyone is comparing explosion-proof clothing styles on the Internet.

"Team King! This!"

More than two hours later, I finally made a discovery.

Wang Song heard the shouting and rushed over immediately.

“Team Wang, look at the pictures of this seller’s customized model!”

Browsing through the pictures, I compared it with the explosion-proof suit worn by the robber in the surveillance video in my memory. It looked very similar.

"Did you compare?"

"That's right! Exactly the same!"

The detective who found the clue zoomed out the web page, and on the screen were the surveillance screenshots of the robbers during the robbery.

"it is good!"

"Contact them to see if there are any goods sold to BZ City!"

"Others continue to search, trying to find all the merchants selling such explosion-proof clothing at night!"

Mr. Wang made some discoveries here, but the matter is not over yet.

What is certain is that there cannot be only one seller selling this kind of explosion-proof clothing.

So where exactly the robbers bought it, no one can tell. .

Investigating this is just one direction and one possibility. The robbers may also buy the explosion-proof clothing offline in other places instead of online shopping.

There are all possibilities, but every possibility must be completely eliminated when solving the case to be sure that this possibility does not exist.

On the other side, Song Mingguang has obtained the list of all personnel in the three branches through the bank's senior management.

"Contact the Communications Administration and find everyone's phone numbers."

The bank also gave these personnel phone numbers, but there was only one.

But in reality, some people are likely to have two or more phone numbers.

This can only be investigated and verified through the Communications Bureau. (End of chapter)
