And who is this person?

The answer is ready to come out.

"Have you checked Wang Lili's prison visit records?"

Wang Lili was imprisoned three months ago, and since then, she and Zhang Xiaohua have become close friends as if they had discussed it in advance.

You know, Zhang Xiaohua has never had any friends since he was imprisoned for two years.

According to what Wang Shun said earlier, Zhang Xiaohua used to walk alone when he was having fun.

Wang Shun smiled bitterly again: "We have also noticed that Wang Lili is suspicious, but since Wang Lili was imprisoned, no one has come to visit her."

No one either!

Chen Yan smiled.

interesting.

The layout is careful and there are no flaws.

Next, Chen Yan no longer asked, but inspected the ambulance in detail.

Since the murderer killed people in a car, how could he not leave any clues?

I don’t believe Chen Yan.

Visual gene lock is on!

Every corner of the ambulance was reflected in Chen Yan's mind, like a magnifying glass, magnifying everything.

Roof, seats, glass fragments...

etc!

The ambulance was overturned on its side, the back door was open, the glass was broken, and there was a strand of hair on one of the glass fragments.

The hair is yellow, it should be animal hair.

It is similar in color to the dry grass on the ground and is difficult to spot.

How could there be animal hair on the ambulance?

He reached out and motioned to Wang Shun to get a sealed bag, and Chen Yan used tweezers to collect the hair on the glass fragments.

Then he handed it to Wang Shun: "Test immediately what kind of animal hair this is."

Wang Shun looked at Chen Yan in surprise.

It's incredible.

No wonder he was promoted to the third level of Detective Director at just over 20 years old.

This is ability.

They looked at the entire scene countless times and found nothing, but they discovered such an important clue with just one glance.

Don't underestimate this small strand of animal hair.

It's impossible to pull an animal in an ambulance, and there are no animals around here.

When detectives investigate a scene, they always wear shoe covers and gloves and have protective measures.

Therefore, there is a high probability that this thing was brought by the murderer.

"Yes, team leader, I will send it for testing right away!"

After the on-site investigation, Chen Yan went to the corpse refrigeration room.

Two housekeepers and one doctor died.

Opening the body bag, Chen Yan's eyes burst with anger!

Two back-office colleagues suffered fatal injuries to their carotid arteries, and one suffered a smooth and everted wound.

But the other person's wound was not caused by an ordinary sharp weapon.

The wounds were crisscrossed and torn, and there was mercury residue inside.

Recalling the broken blood pressure monitor on the ambulance at the crime scene, Chen Yan was surprised: "Is it a blood pressure monitor?"

Although Wang Shun was surprised that Chen Yan could determine the cause of the wound so quickly, he still nodded: "It is indeed a blood pressure monitor."

Chen Yan squinted and looked at the three corpses.

The neck injuries of a housekeeper and a doctor were all caused by sharp objects. There is no reason to use a blood pressure monitor to kill people.

Therefore, there is only one possibility: the clerk was killed by someone in the car!

After the car overturned, the people in the car and the people outside the car worked together, and instantly eliminated the two gun-wielding security guards.

As for Wang Lili’s profile, she is a nurse at a hospital owned by Ruihao Pharmaceutical. She likes sports, fitness and...

free sparring!

As for the doctor, he has no fighting ability and must have been silenced because he saw the murderer's face.

This also explains why the driver was not killed.

Since the other party was unconscious, it was naturally impossible to see the murderer's face.

In order to rush for time, the other party did not kill the driver.

Wang Shun zipped up the body bag for one of his internal colleagues who died: "This little guy, his name is Wang Jun. He only joined the police three years ago and used his father's police number."

Enable siren?

In China, the term "alarm siren activated" is used only when parents engage in detective work and die, and their children continue to join the police.

This is inheritance!

Chen Yan's previous life also had a similar inheritance.

The most the siren he had ever seen activated was three times.

Grandpa and father all sacrificed their lives.

In the end, the policeman who used his ancestral siren also died on the job!

Especially those who work in the police force have the most inheritance.

Snapped!

Chen Yan stood at attention and saluted: "Wang Jun! I promise you and your elders in heaven that we will seek justice for you!"

…

The first supervisor of the iron city.

Accompanied by Wang Shun, Chen Yan inspected the protection situation of the entire prison.

As Wang Shun said, the scope of the supervision is very strict, and the supervision, cleaning, and management of the chefs are very strict.

Moreover, Wang Shun and the others also checked the surveillance. Therefore, it is unlikely that Zhang Xiaohua's pregnancy was caused by an insider.

The first supervisor of the iron city is actually quite helpless.

A female prisoner who had been detained for two years became pregnant for no reason...

What a shame.

Liang Jianguo, the person in charge of the prison, followed Chen Yan as he walked in the playground where prisoners were allowed to relax.

"Team Leader Chen, all the supervisors, including me, have exposed eighteen generations of our ancestors, but nothing has been found."

Liang Jianguo is full of bitterness. No matter what happens in the end, he should not have to think about it anymore.

"The No. 1 Prison in the Iron City was renovated eight years ago. It was designed in accordance with relevant standards and only accepts female prisoners after passing the inspection."

Liang Jianguo shook his head: "Tell me, did the other party dig a tunnel to bring the things in?"

Don't be ridiculous, that was a hundred years ago.

Today's supervision is all about pouring high-grade concrete on the ground. Not to mention digging tunnels, even if the crusher goes directly on it, it will take a lot of effort to break it.

Liang Jianguo looked up at the sky and saw a big bird flying by: "Could it be the son God sent to her?"

Chen Yan followed Liang Jianguo's gaze and looked to the sky, and a flash of light flashed in his mind.

"Maybe...it's really a gift from the sky!"

Liang Jianguo: "..."

Wang Shun: "..."

Although the two of them were surprised, they quickly realized what Chen Yan meant.

"Team Leader Chen," Liang Jianguo shook his head hurriedly: "I know what you mean. The drone sent something in to make Zhang Xiaohua pregnant?"

"It's impossible. We have so many guards here every day. If there is a drone, how can we not see it!"

Wang Shun also nodded: "Team leader, Supervisor Liang is right, and there is a no-fly zone for drone flight. The sky above the supervisor is recognized as a no-fly zone in the built-in map of the drone. You can't fly at all without permission."
