Chapter 527: Serial Murder Case The atmosphere in the car was silent for a while.

Both Chen Yan and Li Hong have a deep understanding of Wang Fenglei's feelings.

Some cases, if not solved, will be like a fish bone stuck in the throat forever.

Every time you take a breath, it stings your nerves.

But returning to the case itself, Chen Yan still has a question.

"Team Wang, I have a question that I don't quite understand."

"So many years have passed since the case, and the interval is so long, why do you think this is a serial murder case?"

"How do you know that the other person is the same person?"

"Taxi drivers were killed. In terms of probability, especially more than ten years ago, there were probably similar cases every year in every city."

"How did you know that the other party was a serial killer?"

"Also, ten years have passed since the case that happened last night and the last time the murderer committed a crime. How can we be sure that the other person is the serial murderer of that year?"

Chen Yan’s question is not unreasonable.

More than ten years ago, the murder of a taxi driver was a crime with a relatively high proportion of robbery and homicide cases.

As Wang Fenglei said, mobile payment had not yet emerged more than ten years ago, and taxi drivers only collected cash.

Such a group that always has cash in their hands is naturally the target of many vicious criminals.

When I was in the police academy, the professor specifically talked about data in this area.

In large cities like Liancheng and Shenshi, more than ten years ago, more than one or two taxi drivers would have accidents in a year.

But why is Wang Fenglei so sure that these cases were committed by the same murderer?

Also, if someone else imitates the crime, is it possible?

Wang Fenglei gave the answer.

"Because of the murder weapon!"

"The murder weapon?"

"Yes, it's the murder weapon!"

"Fifteen years ago, there were even six murders in total, two of which were taxi drivers who were robbed and killed."

"However, except for this serial murder case, the other five murder cases were all solved that year."

"In the following years, although there were successive cases of taxi drivers being robbed and killed, they were all solved one after another, and there were no unsolved cases."

"There are only those four cases without any clues, and the four drivers who were killed were all killed with the same murder weapon."

"What weapon?"

"Probe!"

"Probe?"

Faced with Chen Yan's doubts, Wang Fenglei did not introduce it in detail.

"It's hard to explain exactly. Just turn a corner and you'll arrive at the scene. You'll understand it when you get there."

After the car drove out of the airport, it did not go directly to the city, but went straight to the scene.

"Is this an abandoned factory area?"

Wang Fenglei nodded: "Yes, this place was originally a cement processing plant. It was moved out five years ago due to environmental pollution problems. It is now vacant. This is where we found the murdered taxi driver."

The car turned the corner and entered the sight of tall weeds.

There has been no human habitation in five years, and the original cement factory has become overgrown with weeds.

The car was driving on the cement road, less than 100 meters away, when we saw the warning line.

A group of detectives are investigating the scene.

"Chen Yan, get out of the car. This is the crime scene."

After getting out of the car, Chen Yan first put on his gloves and boot gloves, followed by Liu Qingshan and others behind him, and walked into the scene.

There are weeds half as high as a person on the concrete roadside. It is summer, the grass is tender green, and there are obvious signs of tires running over it.

Passing through more than 20 meters of grass, there is an open sandy field. A yellow and green taxi parked in the middle of the sandy field.

Because it is full of sand and gravel, there are very few weeds here, just a few scattered around.

Five detectives responsible for on-site investigation are working.

"You guys take a rest first, Team Leader Chen is already here."

These detectives were all members of the Shen City Detective Team. After Wang Fenglei and Chen Yan arrived at the scene, they asked these people to rest first.

"Chen Yan, I'm personally watching this case. You go to the scene first, and I'll give you the basic information."

Chen Yan nodded. According to normal procedures, this case should not be led by Wang Fenglei himself.

Because Wang Fenglei's current position is not only the captain of the Shen City Detective Team, he is also the deputy captain of the Liao Provincial Detective Brigade.

With his level, he no longer has to personally lead the investigation of the case.

However, this case is part of a series of cases. Wang Fenglei has handled this case before, and now no one can stop him from participating in the investigation personally.

In the car, Chen Yan knew that the case back then had become Wang Fenglei's heartache.

Just like what his master, the resigned captain, told him when he retired, this case must be investigated.

In fact, Cao An, the captain back then, was the one who took the blame.

Without his resignation, Wang Fenglei's career would have ended ten years ago.

Entering the taxi, Chen Yan immediately activated the gene locks on smell and vision.

Wang Fenglei followed Chen Yan and introduced the basic situation.

Regarding this case, Wang Fenglei knew that it would probably still be impossible to solve it on his own.

I couldn't figure it out ten years ago, so it's unlikely that I can solve it now.

Although the technical means of solving crimes have improved a lot compared with ten years ago, solving the case cannot be solved by technology alone: ​​"The reporter is the wife of the taxi driver, and the taxi driver is a night shift driver."

"Night-shift taxi drivers in Shen City usually pick up the taxi at 5pm and return it at 6am the next morning."

Wang Fenglei is very familiar with the taxi industry in Shen City: "Of course, some drivers have their own agreed time, but probably the night shift drivers will pick up the taxi before the evening rush hour and hand it over to the day shift driver before the morning rush hour."

In this way, both day shift and night shift drivers have peak hours, and the difference in money earned is not very big.

"This taxi driver was supposed to deliver the taxi to the day shift driver at 6 o'clock this morning, but the taxi driver did not wait for the taxi and did not answer the phone. The day shift driver contacted the night shift driver's wife."

"The other party called the police at 9 o'clock this morning. We contacted the taxi company and retrieved the vehicle's positioning system. We found the taxi and the murdered driver in the factory area, and that's when we discovered the taxi."

While listening to Wang Fenglei's introduction, Chen Yan carefully observed everything in the car.

The driver was lying on the steering wheel in the driver's seat, and there was a lot of blood in the car.

Observing carefully from the passenger seat, Chen Yan finally understood what Wang Fenglei was talking about with the probe committing the crime.

There was a probe in the deceased's right carotid artery, connected to a hose under the driver's seat.

The sharp part of the probe was completely inserted into the carotid artery of the deceased.

"In previous cases, did the murderer use similar modus operandi?"

Wang Fenglei nodded: "Exactly the same!"

"Not only the modus operandi, but also the probes and hoses used are exactly the same as those ten years ago!"

Chen Yan frowned.

Use a probe to bleed, causing the deceased to die...

This modus operandi is very special in itself.

The other party actually used the same probe and hose to commit the crime ten years ago. Why?

Demonstrate to the detectives handling the case?

Or is it obsessive-compulsive disorder, or some other reason?

This modus operandi is unusual.

Generally speaking, it is impossible for the taxi driver to be bled quietly by the other party. He will definitely resist, but there is no trace of resistance in the car.

The clothes of the deceased were neat and tidy, and the hanger on the bridge was not displaced or damaged at all.

Did the murderer bleed the driver after subduing him?
