The situation at the scene did not look like an ordinary theft scene at all.

If you are rushing for money, why don't you take gold.

What was the other party running for?

Chen Yan walked to Zhang Chaoyang's side.

"If the other party really didn't come for property, then what exactly did the thieves come for?"

"First, it's just for Hu Yuefei's archives!"

Chen Yan thought of this when he was at Hu Yuefei's house.

Why did the thieves only take the cash and gold jewelry in the safe.

Is the gold in the jewelry box not gold?

Hu Yuefei's house was not rummaged, which could be explained by the fact that time was pressing, and the thief was very time conscious.

But what about the jewelry box on the table, just under the safe?

If you catch a handful of things, the gold jewelry inside can be taken away.

However, the thieves did not grab the tens of thousands of gold at hand.

Are all thieves so generous now?

In the safe, in addition to cash and gold jewelry, there are three things left.

Archives, small boxes, and diaries.

"Find out which companies or units Hu Yuefei has done security design for, especially the jewelry stores, banks and other units."

"In addition, carefully inspect the file bag in Hu Yuefei's safe."

"Assessed by the technical department, is there a possibility that the seal has been opened and re-pasted."

"Also, the bottom of the portfolio should be checked carefully."

In fact, Chen Yan has probably seen it once.

However, if the file bag is cut open by a sharp blade at the bottom and then sealed with self-adhesive, it is difficult to see from the outside.

It must be opened, and a final conclusion can be made after a comparative test.

"There is also Wu Kaiyue's small box. When I checked it, I found that the metal wires connecting the two small hinges of the box had traces of being hit by sharp objects."

"Look, what the key inside is for."

...

All deployments are over, and it is already evening.

Although the case is somewhat suspicious, Chen Yan is actually relatively easy.

No matter how big the theft is, it is nothing more than a matter of more money and less money.

At least no life.

No amount of money can be compared with a human life.

Therefore, there are many murder cases being investigated, and this kind of theft is trivial in terms of pressure.

In the evening, Chen Yan accompanied Xiao Yu to have a barbecue.

The couple's recent days have been rather sluggish.

Recently, Chen Yan and Shen Yunyi fell in love with sea fishing.

On weekends, I often go fishing.

Chen Yan didn't know that Xiao Yu actually had a private dock.

A luxury yacht that is parked in the marina harbour all year round.

According to Ms. Xiao Yu's account, the yacht has been sold for two years, and the number of times it has gone out has not been as many as the sea fishing in the past few days.

Shen Changhai doesn't like sea fishing very much, saying that he doesn't have that kind of leisurely feeling.

And no matter how calm the sea is, there are still fine waves.

Old comrade seasick.

"Boss, two more grilled oysters!"

On a good day, there is also a disadvantage, that is, the cost of raw oysters.

the next day.

Chen Yan did not wait for the good news brought back by the three people in the 2nd Detective Unit.

Waiting, is another report on the investigation of the theft.

The case took place in the jurisdiction of the Detective Unit 1.

Liu Qingshan called early in the morning: "Chen Yan, the amount involved in this case is relatively large, would you like to come and help?"

Master invited him, so Chen Yan naturally wouldn't refuse.

Moreover, when Chen Yan heard the report, for some reason, he thought of the case of Hu Yuefei's safe being pried.

"Master, I'll be there soon."

...

42 Lanling Street.

Lanling Street, no one in Liancheng does not know this place.

This is the largest pedestrian street in the city and one of the busiest places for nightlife.

Liu Qingshan was even more familiar with this place and could no longer be familiar with it.

Every house, every clubhouse, every private theater, every SPA bathroom, etc., Liu Qingshan has swept it no less than three times.

Many young ladies who did not go home were sent home by Liu Qingshan on this street.

When Chen Yan arrived, Liu Qingshan and others had blocked the scene.

"Chen Yan, you are here."

Chen Yan nodded and looked at Liu Qingshan: "Master, what's the situation?"

"It was the headquarters of a jewelry store that was stolen."

"A big loss?"

Liu Qingshan nodded: "This jewelry store has 5 branches in Liancheng."

"Every night after get off work, the precious jewelry from the other four branches will be transported to the jewelry store's headquarters store for preservation."

"And, just three days ago, this jewelry house just imported a shipment of diamonds worth 3 million, all of which were stolen yesterday."

"At present, the overall loss is about 5 million."

When Chen Yan walked into the store, a team of detectives was investigating the scene.

"The main store of this jewelry store, the front hall is the jewelry display area, and there is a secret room of about six square meters in the back for storing jewelry."

In the front hall, detectives collect fingerprints and other information on counters, glass, doorknobs and other places that may leave traces of thieves.

Passing through the front hall is the secret room that Liu Qingshan said.

At this moment, the safe door of the secret room was wide open, and there was a mess inside.

Several empty boxes were scattered on the ground.

"Several boxes, originally containing diamonds and jewelry necklaces, were stolen."

"The surveillance should have photographed each other, right?"

Inside the secret room, there are two cameras.

One is above the safety door and one is opposite the safety door.

In the entire secret room, there is no camera blind spot.

Moreover, in places like this, the camera must be frequently repaired, and the possibility of failure is not large.

However, Liu Qingshan shook his head: "The surveillance did not capture anything."

Nothing was photographed?

how is this possible?

"camera is broken?"

Liu Qingshan shook his head: "The camera is not broken, but..."

Liu Qingshan brought Chen Yan to the secret room.

Around the corner is a power distribution box.

"The other party turned off the air switch that powers the monitoring device in the distribution box."

air switch?

Liu Qingshan led Chen Yan to move forward. It was a small warehouse.

"Here is the uninterruptible power supply that powers the safety door, which was also destroyed by the thieves."

Liu Qingshan pointed to the safety door: "The door that weighs half a ton opened by himself..."

...

Detective Unit 1 conference room.

"An acquaintance commits a crime, it must be an acquaintance committing the crime!"

"The other party actually knew exactly that the air switch that cut off the surveillance video, and the uninterruptible power supply hidden in the safety door of the small warehouse."

"If it wasn't for their internal staff, how could outsiders know?"

The detectives of the first team are holding a case analysis meeting.

There is not a single bit of information about this theft.

Surveillance video in the jewelry store, although the face of the thief was not captured.

However, the video on Lanling Street was captured.

The theft happened at three in the morning.

Although Lanling Street is known as the gold-selling cave that never stops, it is the least popular time of the day at three in the middle of the night.

On the street corner, there are only a few vomited drunks.

three people.

Liu Qingshan pointed to the video captured by a public surveillance camera on Lanling Street: "Three people committed the crime."

"All masked, and wearing black tights, even, everyone."

Liu Qingshan put a screenshot of the video: "These three people have black socks covering their feet, gloves on their hands, and neck covers on their heads."

"On the whole body, except for the eyes, no part is exposed."

"In less than a minute, 58 seconds to be exact, the two of them went out, and the three of them left Lanling Street."

58 seconds!

Three people completed the five million theft.

This speed...

"If, I mean, if someone was nearby at the time, they would call the police when they saw the thief."

Liu Qingshan looked solemn and looked at everyone: "Can this person complete the alarm within 58 seconds?"

Everyone, looked at each other.

When a person suddenly sees theft, his heart will definitely be nervous.

Make a call, call the police, explain the police situation, and explain the address.

It's hard to do without a minute or more.

Unless the person is trained, the psychological quality is very powerful.

See the theft, still in danger.

But the reality is that very few people can do this.

If nothing else, just say the address.

The first reaction of the reporter would definitely say Lanling Street.

At the beginning, Lanling Street was 3 kilometers long and had thousands of shops.

This is a pedestrian street again, where did you ask the police to find you?

"So, the other party must have undergone repeated practice and are very familiar with the security situation of the jewelry store."

"The two people who entered the door, one went straight to the uninterruptible power supply of the small warehouse, and the other went straight to the air switch of the distribution box."

"Then, the two went straight to the secret room behind the safety door. In just ten seconds, all the jewelry was swept away."

Liu Qingshan has rich experience after all.

After the on-site investigation, cooperated with the monitoring, the other party's crime time, the first time to simulate the thief's crime process.

This time, Chen Yan was invited by Liu Qingshan to come and help.

At the moment, there is no comment.

This theft case made Chen Yan feel heavy.

The other party has a clear understanding of the security measures of the jewelry store.

These things do not mean that the employees who work in the jewelry store know it.

That employee has nothing to go back to study the distribution box.

The point is that there are a total of twelve air switches on the distribution box.

And Chen Yan has seen it, and there is no indication of what each switch is on.

There is also an uninterruptible power supply in the small warehouse.

It is a set of batteries, hidden behind the cabinet.

The thieves did not violently destroy it, but directly pulled the blocking switch of the battery.

This is pre-set.

Just to deal with emergencies.

After being pulled apart, it can be recombined in situ without causing damage to the power supply.

This point, no professional knowledge, generally do not know.

What's more, the small warehouse is usually locked and not open to the clerk.

The thieves did not enter the small warehouse by breaking the door lock.

Instead, the emergency pull bolt above the door was pulled.

This is a special emergency door for the uninterruptible power supply equipment room.

It is to be able to open the door for the first time to deal with the situation such as fire.

And thieves, obviously know everything in advance.

Therefore, the other party can complete the theft in just 58 seconds.

"Captain Chen," Liu Qingshan walked over to Chen Yan after expressing his opinion, and looked at everyone: "Captain Chen is familiar to everyone."

"This case involves a huge amount of money, and the thieves have meticulous methods of committing the crime, so I invited Captain Chen to come over to help the staff."

"Everyone is welcome!"

wow wow...

For Chen Yan, there is really no one who is unfamiliar with the Detective Unit 1.

When Li Hong was still there last time, Chen Yan had cooperated with the first team.

Playground homicide.

Later, the first team and the second team jointly acted to investigate the case of the other side flower No. 3.

"Hello Captain Chen!"

"Welcome Captain Chen to guide the work!"

Liu Qingshan is the matter of Master Chen Yan, and everyone in the first team knows it.

So The two teams cannot be said to be one family, but the relationship is good.

"Hello everyone, see you again."

Chen Yan got up and smiled: "I'm not guiding, I'm just coming..."

buzzing...

Just after saying a few words, Chen Yan's cell phone rang.

It's a WeChat message.

Before the case analysis meeting, Chen Yan sent a WeChat message to Zhang Chaoyang.

Now, information feedback.

However……

The thing that Chen Yan didn't want to happen the most happened.

Just a glance, Chen Yan's face suddenly became very ugly.
