On The Day Of My 100th Blind Date, I Arrested My Date

Chapter 473: Half a Fingerprint

On the projector, there are photos of the accident vehicle.

Zhang Chaoyang began to report: Team Chen, after the investigation of the accident site, we asked a third-party appraisal technician to conduct a technical appraisal on the scene again.

From the trajectory of the vehicle, the entire process of the traffic accident has been re-deduced.

According to the degree of damage to the vehicle and the analysis of the characteristics of the impact on the mountain, the speed of the vehicle hitting the mountain was 96 kilometers per hour.

96 kilometers per hour?

This speed surprised Chen Yan.

The speed limit on the ring road in the northern suburbs is 100 kilometers per hour, and Zhang Baoquan's vehicle was traveling at a speed of 96 kilometers per hour before hitting the bottom of the mountain. Although the speed limit was not exceeded, there is one point that is very unreasonable.

That's where the vehicle crashed.

The vehicle accident occurred at a T-junction, turning left from east to west to the Ring Road, then turning right to connect to National Highway 212.

In the early hours of this morning, after playing mahjong from the Juyou chess and card room, Zhang Baoquan should have driven back to the city, that is to say, his normal driving route should be from east to west, then turn left and continue driving on the ring road.

At that time, turning left into the ring road was a turn of about 70 degrees.

With such a large camber, Zhang Baoquan's speed reached 96 kilometers per hour. There is no need to turn, this is a special takeoff.

Turning at this speed, even if it didn't hit the mountain, it might be an accident, right?

Zhang Chaoyang nodded, and played the next photo: The answer given by the technician is also the same.

Judging from the situation at the scene, as well as comprehensive analysis of the data read from the vehicle's driving computer, the vehicle was traveling very fast at that time, and there was no safe speed for turning.

Furthermore, based on the analysis of the tire tracks at that time, it can be basically determined that the impact of the vehicle was straight during the impact process, and the direction did not deviate in any way.

At the same time, technicians also conducted a comprehensive inspection of the brake system.

Both brake pads and rotors are in good condition with no signs of excessive wear.

The electronic unit that controls the brakes, the brake pedal and the hydraulics, there is nothing wrong with that either.

Is there any trace of man-made damage?

Zhang Chaoyang shook his head and switched the projection picture: This is the inspection picture of all the braking systems of the vehicle.

The front wheel has been completely scrapped due to the impact, and the brake system has also been completely damaged, and there is no way to detect it.

But the brake system of the rear wheel of the vehicle is indeed intact, without any trace of man-made damage.

Moreover, even if the braking system of the front wheels is passive, if the brakes are applied during the accident, the braking of the two tires of the rear wheels will greatly limit the speed of the vehicle.

Therefore, it is initially judged that there is no major problem with the braking system.

How's the airbag investigation going?

Hearing Chen Yan mention the airbag, Zhang Chaoyang nodded emphatically: We have made important discoveries about the inspection of the airbag.

click.

The projection switch, is a photo of a vehicle part.

Chen team, this is the fuse box of the accident vehicle.

After the accident, the front of the vehicle collapsed very badly, and the fuse box also shattered into several pieces, but it was not completely damaged.

Look here, this...

Zhang Chaoyang pointed to a safety pin on the screen fuse box: This safety pin is the safety pin that controls the detonation of the vehicle's airbag.

The first condition for the ejection of the airbag is that the induction device is triggered.

This safety pin is the fuse that guarantees power to the sensors and airbags.

Once there is a problem with this thing, even if the sensor is triggered and the airbag function is intact, the airbag still cannot be deployed.

Switching the projection is a safety plug that has been pulled out.

Look, everyone, one pin of this bolt is broken and missing.

The projection magnification is just a pin of the safety plug.

And if the pin is missing, the pin is actually in a power-off state, which means that the airbag of this car is actually in a non-working state.

Missing pins, can it be determined that it is man-made?

This is what Chen Yan is most concerned about.

If there are such failures under natural conditions, then there is a non-human possibility.

If there is this possibility, it cannot be conclusive evidence.

Sure enough, Zhang Chaoyang shook his head: According to the analysis of the technicians, there are two possibilities for the breakage of the safety pin.

One is man-made. This probability is the greatest, but it is also possible that the pin itself is broken. The possibility of the latter is very small, but it cannot be said that there is no such thing.

Of course, to judge whether the pins are artificially damaged, we focused on the socket of the pin.

Another photo was shown on the projection.

Under normal circumstances, no one will touch this kind of insurance latch. We have checked the maintenance records of this car, and there is no problem.

It is basically possible to rule out the possibility that the pins of the insurance pin are broken due to maintenance.

Also, if it's man-made, the other party is likely to throw away the pins, but everyone, look here...

The photo on the projector was enlarged, and Chen Yan and others could clearly see a broken pin in the socket.

We found that the broken pins were still in the socket, which made it difficult to determine whether the pins were man-made or broken naturally.

Chen Yan nodded.

What Zhang Chaoyang meant was that if there were no broken pins in the socket, it would be certain that the broken pins of the safety pin were man-made, because naturally broken pins could not escape the socket by themselves.

But now, the broken pin is still in the socket, which is hard to judge.

Because of this reason, the pin may be broken naturally, or it may be man-made.

It's just that after breaking the pin, the person didn't throw the pin away, but plugged it back into the socket again.

Letting out a foul breath, Chen Yan leaned back in the chair.

If it's just that, it's going to be difficult.

However, Zhang Chaoyang's discovery must be more than that, otherwise, he would not say that he has made a major discovery.

Sure enough, Zhang Chaoyang paused: However, we found another piece of evidence.

Everyone look here. Zhang Chaoyang switched the projection, and it turned out to be the broken pin: Later, we took out the broken pin in the socket, and found half a fingerprint on this pin.

Half a fingerprint?

Chen Yan leaned forward, and there were fingerprints, which meant that this thing must have been destroyed by humans.

Yes!

Zhang Chaoyang's tone was a little excited: The other party should be very cautious.

We found no fingerprints on the vehicle's fuse box or on the fuse latch.

The other party should have been wearing gloves when he damaged the safety pin, but the stitches on the safety pin are relatively small, and wearing gloves is not easy to break, so the other party probably took off the gloves at this time, but he did not expect that such a small His fingerprints can be left on one of the stitches.

Half a fingerprint!

Enough, even if it is not a little fingerprint line, it can be compared to find out who broke the pin of the safety latch.

Moreover, it is not difficult to delineate the scope of this person.

The fuse box is in the engine compartment. To access this thing, you must have a car key to open the engine cover.

Besides Zhang Baoquan himself, who else has access to the car keys of this car?

Nothing more than his family and the maintenance workers of the 4S shop.

However, the maintenance worker of the 4S shop has no grievances with Zhang Baoquan, so it is unlikely that he will do such a thing.

The most likely one is Zhang Baoquan's second wife, Wang Yue.

Wang Yue and Zhang Baoquan have no enmity, but they have interests.

However, even if the possibility of tampering with the maintenance workers of the 4S shop is relatively small, they still cannot give up.

And these people are still easy to find, check the maintenance list of the vehicle, which worker did the maintenance, this is all recorded.

Chaoyang, organize people to compare these half fingerprints immediately!

The point is Zhang Baoquan's wife, and there will be maintenance workers who have maintained the car!

***************************

In addition to the investigation of airbags and braking systems, there is another key work, that is, the driving recorder.

Zhang Baoquan's car is a flagship sedan with a very high configuration, and the car itself has a built-in driving recorder.

When the accident happened yesterday morning, no one knows what happened, but the driving recorder should have captured some of the incident.

How's the dashcam investigation going?

However, this time Zhang Chaoyang shook his head in disappointment: When we inspected the vehicle, we found that the memory card of the driving recorder had been pulled out.

Unplugged?

The murderer pulled it out?

Chen Yan was a little puzzled.

That's why this case is a bit odd.

First, judging from the clue that the pin of the safety pin of the airbag was broken off intentionally, the murderer wanted to kill Zhang Baoquan, but the purpose was to cause Zhang Baoquan's death in an unexpected way.

However, if the murderer really wanted to cause Zhang Baoquan's death in an unexpected way, then the reasoning and the actual situation found at the scene are somewhat inconsistent.

If the murderer wanted to forge the scene of the accident, there was no need for him to remove Zhang Baoquan's body and crush it with a pulverizer in the pig farm.

Doing so will serve no purpose other than attracting the attention of the police.

Unless the other party wants to destroy the body and cover up something.

Wants to create an accident, but shreds corpses with a shredder in a high-profile way.

What is the murderer trying to do?

Also, the memory card in the driving recorder disappeared.

This also conflicts with the purpose of creating surprises.

If the murderer really wanted to create an accident and pull out the memory card, everyone would know there was a problem.

Didn't you expose yourself on purpose?

The meeting is over quickly.

Zhang Chaoyang compared the fingerprints according to Chen Yan's request.

No matter what the murderer's purpose is, as long as the person is found, everything will be clear.

Unexpectedly, and of course expected, Zhang Chaoyang returned to Chen Yan's office after only half an hour.

Captain, the fingerprint comparison... has the result!

Chen Yan also had some differences, but there was a result so quickly, a person flashed in Chen Yan's mind.

Wang Yue!

Zhang Baoquan died, and Wang Yue owned half of his property.

Moreover, a month ago, Wang Yue bought Zhang Baoquan a 5 million accidental death insurance.

The beneficiary of the insurance is herself.

It can be said that if Zhang Baoquan died unexpectedly, Wang Yue would be the biggest beneficiary.

Then, as a matter of course, Wang Yue is naturally the first suspect.

Moreover, before Wang Yue was interrogated, his fingerprints and other information had already been collected.

As soon as the meeting here ended, Zhang Chaoyang arranged for the detectives to compare the half fingerprint found on the safety pin with Wang Yue's fingerprint.

Then start arranging information inquiries for workers who repair and maintain cars in 4S shops.

As a result, the 4S shop had just contacted the other side, and the result of the fingerprint comparison here has already come out.

The half fingerprint found on the broken pin of the safety latch belonged to Wang Yue!

Taking the comparison report, Chen Yan read it carefully.

The comparison accuracy rate is 100%.

The case is likely to be solved.

Go, go to the interrogation room and interrogate Wang Yue again!

Half an hour later, Chen Yan met Wang Yue in the No. 1 interrogation room.

Compared with last night, Wang Yue is a little haggard today.

The delicate makeup on his face is gone, his eyes are bloodshot, and his mental state is not very good. It is obvious that he did not have a good rest last night.

Even, Wang Yue probably didn't sleep all night last night.

Without any nonsense, Chen Yan directly put the fingerprint comparison report in front of Wang Yue.

Wang Yue, take a look at this.

Wang Yue picked up the report with some doubts, looked at it twice: What is this?

What?

Wang Yue, this is a fingerprint comparison report.

We found a fuse pin with a broken pin in the fuse box of the accident vehicle your husband was driving.

This thing... you are not unfamiliar with it?

Safety latch?

Hearing Chen Yan say the word insurance plug, Wang Yue's expression changed suddenly.

The hand holding the fingerprint comparison report began to tremble.

The cold sweat on the forehead soaked instantly.

This is impossible……

You...how could...

I...I was...wearing gloves...impossible...

Wang Yue murmured impossible words to himself, and his eyes were full of fear.

Wang Yue, it was you who tampered with your husband's car and finally caused the car accident, right?

Now explain, we can try to give you leniency...

No!

Suddenly, Wang Yue's hysterical roar interrupted Chen Yan's words.

Impossible! Impossible! You must be lying to me!

I was wearing gloves to pull out the pin, how could it leave fingerprints?

Gloves?

Chen Yan sneered: Wang Yue, you did wear gloves when you pulled out the safety latch, and we didn't find your fingerprints on the safety latch either.

But were you wearing gloves when you broke the stitches?

Break a pin?

You...you found my fingerprints on the pins I plugged into the socket...that thing is so small...how is it possible?

Hehe, Wang Yue, nothing is impossible, if you want others to not know, unless you do nothing!

Say, why did you kill Zhang Baoquan?

Also, after Zhang Baoquan died early yesterday morning, who put his body into the pig farm and smashed it?

Faced with Chen Yan's questioning, Wang Yue acted as though she had never heard of it, and just muttered to herself: How is it possible...how is it possible...

Wang Yue seemed to be caught in a kind of self-doubt.

After a while, Wang Yue seemed to have recovered from his self-doubt, stroked his somewhat messy hair, and looked at Chen Yan again.

Officer Chen, I didn't kill my husband.

Without waiting for Chen Yan to ask, Wang Yue continued, I admit, I broke the pin of the safety latch.

I'm not afraid to tell you, not only that, I also plan to destroy the hydraulic device that controls the brakes.

It's just that before I could do that, he died!

Wang Yue explained all the things she had done.

It's not a day or two since I wanted to kill Zhang Baoquan. I wanted to do it a long time ago.

He married me and didn't treat me as a family at all. The two of us had an agreement before marriage.

He pays me regular living expenses, but if he dies, I don't get a cent of his property.

I told him about it two months ago, but he still didn't agree to void our pre-marital property agreement.

His property will be given to his daughter in the future. I have no choice but to think of other ways.

I bought Zhang Baoquan a personal accidental death insurance for him a month ago.

The insurance amount is 5 million. As long as he dies, although I won't get his property, I still have 5 million in compensation.

Then I started to implement my plan. A week ago, I broke the pin of the safety latch of the airbag of Zhang Baoquan's car.

Originally, I planned to fix the brake system next week. You know, I used to work in a BMW 4S shop. Although I am not proficient in these things, I know how to do it.

In order to prevent you from finding me out, I bought an accidental death insurance for myself.

However, Zhang Baoquan's car accident yesterday has nothing to do with me.

He died before I could do anything with the brakes.

I didn't lie about one thing. I was at home the night of the incident and didn't go anywhere.

If Zhang Baoquan's death is related to the failure of the vehicle's airbag, I am willing to take responsibility, but I did not kill him.

As for why someone took his body to a pig farm and smashed it up, I really don't know.

This time, Wang Yue did not lie.

Compared with when Wang Yue was interrogated yesterday, she has a natural expression on her face today, and there are no small movements in her hands, and she speaks without thinking, without thinking, and is very smooth.

However, if what Wang Yue said is true, then how did Zhang Baoquan get into a car accident yesterday morning?

And who was the one who crushed his body?
