Mystery Case Tracing [Criminal Investigation]

The results of the vehicle inspection first came out with a preliminary conclusion: Except for the impact damage, the off-road vehicle was not abnormal in other conditions. Lei Zhibin’s black Audi initially detected a problem with the brake system, a problem with the steering wheel, and the driver’s seat was changed, mainly because the seat belt buckle was changed. Other deep-seated problems are still being tested.

The big guy was busy all night and the whole morning. Lunch was just two mouthfuls, rushing to produce various results, checking various information, and a piece of news detonated again.

The car accident that occurred in the early hours of the morning was posted by the media, with the headline: "Lei Zhibin, a well-known real estate company, caused one death and one injury in a car accident. Is it drunk driving or DU driving?"

The photo was taken before the traffic police blocked the scene, and the accompanying text basically guessed that Lei Zhibin's driving out of control caused a car accident.

Originally, this news didn't have any hot spots. As a result, the following comments that were topped to the top revealed some of the truth.

First floor:

(Four fuzzy phone pictures) I live next to Huihe Road and smoke on the balcony in the middle of the night. I saw a lot of people at the intersection of Huihe Road and Huilong Road. Both roads have been emptied. I don’t know what happened, so I took a photo casually. The car accident caused such a big accident?

The three photos are in different directions, and the roadblocks set up by the traffic police can be seen vaguely. One photo shows the EOD team surrounding the vehicle, with fire trucks and ambulances parked on the side of the road in the distance, and a bunch of people standing on the side of the road.

Second floor:

(Quoting the photo on the first floor, original text) The bomb disposal expert who is standing by the car wearing the same cotton bag! There is a bomb in the car! The people standing on the side of the road can't see what they look like, and judge by their clothes, they are all big men, and there are special police! This is a suicide attack that has been subdued!

Third floor:

A suicide attack by a well-known real estate developer? Is this a precursor to the collapse of housing prices, or is the house going to be fully nationalized and rented instead of sold?

When Qi Chuchen saw this news, he wanted to die on the spot. The result of the rapid development of the Internet is that more and more cases have been unintentionally exposed by the soy sauce masses. With the addition of brain supplements, the truth of the news is not important, but the important thing is that it will be very explosive!

Qi Chuchen's handling of this kind of thing can be regarded as practice makes perfect. Within half an hour, all news and discussions about the early morning car accident on news websites and Weibo were cleared.

Private chats in various chat software, as long as they are not speculating about the qualitative nature of the case, are simply not dealt with by the accident itself.

Qi Chuchen told Zhang Chao that if there were any comments on the above, he would come to him, and he would tell him. Zhang Chao asked him why he didn't just delete or block it. He told Zhang Chao: Freedom of public opinion is relative. The masses need space, and the police also need space. As long as they are not linear, they can coexist. It is a fact that a car accident happened, and it is also a fact that we dispatched a bunch of people, but what is the fact that is invisible on the surface? Need to be announced after police investigation. The masses can be curious about the facts, but they cannot maliciously speculate or even fabricate the facts. The former is freedom and the latter is crossing the line. It will only make things more complicated, and make things seem like they are unable to handle the case. There is really other insider information. Youyou can't stop everyone's mouths, and one size fits all: Defending the people is better than Fangchuan.

Twenty-two hours have passed since the accident, and the lights in several offices of the Municipal Bureau had been on for more than ten hours. Forensic, inspection, trace inspection, criminal investigation, and technology had a Sunday that was not ordinary for ordinary people at the Municipal Bureau, but it was an extraordinary Sunday for them.

The lights in the meeting room on the third floor were on again, and the meeting room was crowded with people.

The technology's all-round detection of vehicles has ended, and Highlander is not abnormal. In the black Audi A6 driven by the deceased Lei Zhibin, the steering wheel, brake system, seat belt buckle were changed, and the cruise control system was changed.

"Change purpose?" Qi Chuchen asked.

"According to our inspection and inspection, during the driving process of this car, if the cruise control function is pressed, it will automatically jump to high-speed driving, causing loss of control. The solution is to manually take over and brake. The braking system is changed, no matter what There is no way to brake in this situation. Either the collision is forced to stop, or the car jumps, and the jumping car will immediately detonate the ZHA egg under the driver's seat.

Interlocked, there is no way to escape... The vehicle detection result caused an uproar in the conference room.

"If the deceased doesn't need to cruise at a constant speed, regardless of high or low speed, he can't stop after driving, right?" Zhu Zhen asked.

"Correct!"

"Did the cruise control start before the crash?" Qi Chuchen asked.

"It's on. The cruise control switch of this car is on the left rear of the steering wheel. Turn it on. The switch is on, but I don't know if it is turned on by the driver or by a fault." A technical answer in charge of vehicle detection.

"This switch is only for cruise control, right? I have never used this before. I don't know if there is a difference between different brands of vehicles. If you only care about this, I suggest you look at the wear of this switch. If you use it frequently and occasionally, you have not even used it. It must be different. Does Lei Zhibin drive this car? How long has it been bought?" Qi Chuchen asked.

"Lei Zhibin usually only travels in this car. I don't ask the driver. He drives the car himself. He changed this car five years ago and it traveled more than 70,000 kilometers." Gao Rui replied.

"It's been on for so long, and I don't use this switch frequently, it should be obvious."

The technician nodded and wrote it down in the notebook.

Anyway, it's dead...

If the traffic police didn't check it carefully at the time, and when the ambulance arrived, they would just open the seat belt and move...the consequences would be unimaginable...

Forensic doctors completed the dissection of Lei Zhibin, and determined that the deceased was suffering from diabetes, high blood pressure, and other conditions that are commonly known as senile diseases and heart health. Although there is high blood pressure, there is no obstruction and bleeding in the brain, not sudden death. The real cause of death was poisoning, and the deceased ingested it to death.

The mineral water next to the driver's seat and the mineral water in the trunk were tested to determine the quality of the water. Every bottle of mineral water that was not opened in the trunk had tiny pinholes on the side of the bottle mouth.

"Whether Lei Zhibin is drinking with the water at hand, or he is more careful about taking a new bottle from the trunk, as long as he drinks water, he can't escape." Qi Chuchen concluded. "I remember diabetes is prone to thirst?"

The forensic doctor nodded and confirmed Qi Chuchen's problem.

Afterwards, various technical experts told about some details found in the inspection and testing.

"If you don’t drink water to escape poisoning, you can’t stop when you get in the car. Whether you’re driving at a constant speed or not, you must loosen your seat belt if you want to jump out of the car. Can’t escape. The person who shots must be very aware of Lei Zhibin’s driving habits and even life and work habits. Does Lei Zhibin drink? Ask back. If he occasionally drinks alcohol and asks for a driver or taxi, this plan may fail. Where did he drive on Huilong Road." Qi Chuchen pressed his right thumb on his cheek, and kept rubbing his chin with his index finger. The thumb was too hard and a small piece of cheek was recessed.

"Lei Zhibin went to an industry gathering last night. For the specific situation, I have asked the relevant organization for the list of participants, and I can get it tomorrow morning at the latest." Luo Hao replied.

"Vengeance and extermination will be investigated together. Next, we will investigate Lei Zhibin’s business status, business scope, and property sources! Tomorrow morning we will continue and visit one by one after getting the party list. This is the last group of people he came into contact with during his lifetime. One omission. Let's take a break now, and we will meet during the shift tomorrow morning." Zhang Chao arranged the next work and announced that the meeting was adjourned.

Qi Chuchen hurriedly turned on the phone. Yan Mu made two calls to him before, but he did not answer, and then sent two more WeChat voice messages. He never had time to manage, and only replied: I need to check things, have a meeting, and leave me alone. sleep early.

This is the tacit understanding between the two of them during this period of time. To be precise, it is the signal transmission code word that Yan Mu realized

It's almost over: if it's fast, it will get off work in half an hour, and it will be an hour slow.

Not sure how long: I can go home, but I’m not sure how long.

The matter needs to be investigated: the case is complicated, and I may not be able to return home tonight or tomorrow night in the next few days.

Gone: disappeared in the same place, the return date of the business trip is unknown.

Qi Chuchen estimated that the voice was also asked by Yan Mu if he would reply, when to reply, and so on, so he just clicked on it.

"My dad suddenly had a heart problem, and I want to hurry back to Canada."

"I have already bought the ticket. Now I go to the airport. You can go back to Shuimo live or stay here to see you. I have arranged for someone to bring you fresh milk and fruit on time. I will call you when I arrive.

Zhang Chao and Gao Rui and Qi Chuchen walked side by side and heard the voice.

"What happened to Yan Mu's father?"

Qi Chuchen shook his head and looked at the voice time. Both of them were sent not long after the meeting. He immediately called Yan Mu back. The cold mechanical female voice reminded: The user you dialed has been turned off. Please call again later. .

Qi Chuchen replied a text: I can't answer it, this matter is troublesome. You take care of yourself and leave me alone.

After returning to WeChat, Qi Chuchen put his phone in his pocket: "Okay, you don't have to go home tonight, continue to work..."

Zhang Chao squinted Qi Chuchen, his red eyes looked like a rabbit, "Go away, you'll be there."

"Where to go back in a while? Ink painting or Yunyin's way home" Zhang Chao blocked Qi Chuchen's idea of ​​staying overnight in the office.

"Yun Yin, go back to clean up the refrigerator, and eat. He doesn't know how long he will be there. He probably has to report the crime when he comes back. The house smells bad."

Qi Chuchen drove the car and didn't go home directly, and then turned to Huilong Road, walked two back and forth at the intersection of Huilong Road and Juhe Road, and stopped by the side of the road. Qi Chuchen looked at the pine tree hit by Lei Zhibin's car in front, replaying the scene in the road monitoring in his mind over and over. Every time it is replayed, new questions keep appearing: What was Lei Zhibin thinking before he died? Did Lei Zhibin realize that he couldn't escape when he noticed the abnormality? Does Lei Zhibin know who is killing him?

There will never be answers to these questions, but another answer is to never give up the pursuit until the guilty confession.
