There is only one reason, and that is the intentional murder of the other party.

Chen Yan looked at everyone: "If it is a stranger, and the murderer doesn't know Yang Miaomiao's parents, then why did he kill them?"

"for money?"

"Impossible," Li Hong shook his head: "I led the investigation at the scene at that time."

"There are about 3,000 yuan in cash in the backpacks of the two elderly people, and they have not been lost."

"The watch worn by Yang Miaomiao's father is also more valuable, and the bracelet and gold necklace her mother wore were not lost."

So, a stranger would deliberately kill two old men?

No money, no profit?

This is unlikely.

"I agree with Team Li's point of view," Chen Yan nodded: "Moreover, from the scene, if Yang Miaomiao's parents were murdered, then the other party should have taken the opportunity to kill the two old men while they were posing on the stone. People pushed it down."

"This will cause the two of them to fall off the cliff on their backs and land on the back of their heads."

"And, one more point, if it was us, taking pictures on the edge of the cliff, would we let strangers approach and give him the possibility of pushing us down?"

"So..." Li Hong's eyes flickered, as if thinking of someone: "That driver..."

Chen Yan nodded: "Yes, that driver is very suspicious!"

"Although, we still don't know how he avoided the surveillance and went up the mountain."

"However, from the current analysis, the driver who sent Yang Miaomiao's parents to play is suspected of being a major crime!"

...

An hour later, the driver has been invited to the interrogation room of the Detective Unit 2 for tea.

"Officer, I don't understand what you're talking about."

Zhao Xiaohu's expression was innocent: "Sister Yang arranged for me to send her parents to climb the mountain."

"At the foot of the mountain, the two old men went up the mountain, and I was waiting for them in the car."

"Afterwards, they never came back, so I started going up the mountain to find them."

"And then they found out they fell off a cliff."

"What's the matter, what happened? It's been half a year since Sister Yang's parents passed away..."

In the monitoring room, Chen Yan and Li Hong were watching Zhao Xiaohu's reaction on the screen.

"His expression is very natural, and he is a little suspicious, not like a lie."

Li Hong has been observing this Zhao Xiaohu's expression.

Chen Yan nodded.

There's nothing wrong with Zhao Xiaohu's expression, but...

"Ask about the time they agreed, and when he went up the mountain and when the body was found."

Through the earphone, Chen Yan gave some hints to Zhang Chaoyang inside.

"Zhao Xiaohu, you don't have to be nervous," the detective in charge of the inquiry was Zhang Chaoyang: "We're just simply checking the situation."

"What time did you arrive at Langtou Mountain, and what time did you come down?"

"Langtou Mountain at 11 o'clock, we made an appointment to go down the mountain at 2 o'clock."

"What time did you find out that something was wrong, and then found the body and reported it?"

"At 2:30, I saw that they hadn't come down the mountain, so I went up the mountain to look for them. I called in the middle, but no one answered."

"At 3:30, I found them falling off a cliff on the north hillside and called the police."

"At that time, there were two groups of people who went up the mountain. They saw me going up the mountain, and they helped me find someone together."

monitoring room.

Chen Yan and Li Hong were still staring at the video.

At this moment, both of them frowned.

"Li team, what do you think?"

Li Hong did not speak for a while.

This Zhao Xiaohu, all questions to Zhang Chaoyang, are all correct.

No hesitation at all.

But the problem is that it has been half a year since Yang Miaomiao's parents passed away.

Half a year later, this Zhao Xiaohu still remembered all the details and time points at that time so clearly, it was no different from the record half a year ago.

That's a bit unreasonable.

Could it be that this Zhao Xiaohu is a child prodigy and has an excellent memory?

If you really want this...you don't have to be a driver.

"This Zhao Xiaohu remembers the details too clearly."

Chen Yan nodded.

"Yeah, more than half a year has passed. Zhao Xiaohu remembers what time he arrived at Langtou Mountain at that time, what time did he take takeaway, what time did he go up the mountain to find someone, what time did he call the police, and how many people were on the mountain..."

"Haha," The reason why Chen Yan asked Zhang Chaoyang to ask about these details, especially the time details, was to listen to Zhao Xiaohu's memory of these details.

"The details are not bad at all, just like memorizing it."

This is a little too deliberate.

Compared with other tangible memories, people's memory of time is very vague.

In particular, the finer the time, the more difficult it is to have specific memory impressions.

For example, when I was in school, I recited an ancient poem.

Maybe you will memorize it in a day, and the content of the poem will not be forgotten for a long time.

However, can you remember exactly which ancient poem you recited that day?

Even, what time it was memorized.

Whether there are such people, there must be, but they must be very few.

Zhao Xiaohu has such a deep memory of what happened in the past six months, is it possible?

Of course there was, after all, two people died at that time.

Zhao Xiaohu, as the first person to see the corpse and report the grievance, should never forget this incident in his life.

After all, the irritating memory of dead people must be very stimulating.

However, because of this, Zhang Xiaohu's memory of that day may only be the moment when he saw the corpse.

Other memories are weakened.

After all, on the day Yang Miaomiao's parents died, the most irritating thing was death itself.

Not what time did they arrive at Langtou Mountain, what time did they receive takeout, and what time did they go up the mountain...

With all the details so clear, it's a little suspicious.

As for Chen Yan, since he has become suspicious of Zhao Xiaohu, it will not be particularly difficult to find evidence.

Or rather, something relatively simple.

"Li team, you stare here first, I'll watch the video of the Langtou Mountain parking lot at that time."

Why was Zhao Xiaohu not suspected at the time?

Two reasons.

One is that Zhao Xiaohu's car has been in the surveillance area.

From the monitoring point of view, after Zhao Xiaohu parked the car, after sending Yang Miaomiao's parents up the mountain, they got into the car.

It hasn't come out since.

The second factor that proves that Zhao Xiaohu has been down the mountain, that is, the appearance of the takeaway.

When the deliveryman came, Zhao Xiaohu got out of the car.

After that, Zhao Xiaohu ate takeaway outside the car.

During this period, Zhao Xiaohu disappeared from the surveillance for 3 minutes.

According to him, it was going to the toilet.

It takes three minutes to go to the toilet, which is normal.

In such a short time, it is impossible to run to the top of the mountain to kill.

It is precisely because of these factors that the staff at the time believed that Zhao Xiaohu had an alibi.

So, if Zhao Xiaohu tells a lie, he is the murderer.

So, what Chen Yan has to do is to find the flaws in the video.

Especially in the range of 11:00 to 1:00.

Is Zhao Xiaohu in the car?

In front of the computer, the video is playing.

Chen Yan concentrated, turned on the visual gene lock, and did not miss every frame.

At 11:00, Zhao Xiaohu's car drove into the parking lot.

Judging from the speed at which the car entered the arena, Zhao Xiaohu entered the arena without any hesitation, parked, and reversed.

Coincidentally, after Zhao Xiaohu stopped the car, he was just below the surveillance camera.

The driver side of the car is facing the camera and the other side is facing the camera.

Can see the front four-fifths of the car, but not the rear.

The car was a commercial car, and Zhao Xiaohu did not enter the driver's seat after sending off the two elderly people.

Instead, from the passenger side of the car, he sat in the business seat at the back.

The picture after that is basically a still picture.

The breeze blew and the branches swayed.

Zhang Xiaohu's car never moved.

During this period, Zhao Xiaohu did not get off the bus.

It was not until the deliveryman entered the surveillance field and parked beside the car that Zhang Xiaohu got out of the rear door on the passenger side.

In the video, it can be seen that after Zhao Xiaohu got out of the car, he stretched for a long time.

Also had a chat with the delivery guy.

After that, there was a video of Zhao Xiaohu squatting on the front of the car to cook.

Then, Zhao Xiaohu disappeared for three minutes, and after returning, he walked around the car a few times.

Walk and watch the time.

Called at 2:10, left the car at 2:30, walked out of the video range, and went up the mountain.

Video...seems to be ok.

Chen Yan learned from the information of the first team when the deceased was found at 3:30 in the afternoon.

It was 4:10 when Li Hong and others arrived.

At that time, judging from the stiffness and temperature of the corpse, the time of death of the deceased was about 4 hours.

That is, around 12:00 in the morning, Yang Miaomiao's parents fell off a cliff.

It was at this time, combined with Zhao Xiaohu's stay at the foot of the mountain, that there was no doubt about this reporter.

"But if it wasn't Zhang Xiaohu, who would it be?"

Chen Yan frowned deeply.

This afternoon, Chen Yan watched the video several times, but found no clues.

eight pm.

Wang Gang was still investigating the whereabouts of Yang Hao's boyfriend last night, but he didn't come back.

There are no clues here, and Chen Yan is not going to stay up late.

Eucalyptus has to be done, and life has to be there.

Miss Yu is still waiting at home.

In the team parking lot, the tank 500 that Miss Yu gave to Chen Yan quietly parked there.

Mmmm, domineering!

Chen Yan really likes this car.

Not so flamboyant and domineering.

The key is that the suspension tuning of this car is very interesting. The suspension in the first half is relatively soft and it is very comfortable to drive.

The second half is more supportive and less prone to roll.

Open the door and the electric pedal automatically extends.

Chen Yan is 1.83 meters tall and weighs about 75 kilograms.

Well, I was fed by the chubby oysters and sea cucumbers in Zhuyuan recently.

Stepping on the electric pedal, the body sinks slightly.

Sitting in the car, Chen Yan suddenly froze.

The finger that was about to press the start button was suspended in the air.

what!

I see!

Zhao Xiaohu, right?

I see where you're going this time...
