Chapter 28: Locking up the suspect

Conference Room 1.

After an all-nighter, everyone was still busy.

In the case of a fatality, being able to take a nap in a chair is a luxury for the police handling the case.

Of course, at this time, not only the criminal police of the criminal investigation detachment were busy, but also the people from the grassroots police station.

Since yesterday morning, all those who are closely related to the deceased will be investigated.

It is impossible for these tasks to be completed quickly by relying solely on the criminal police of the criminal investigation detachment.

Grassroots police stations also need to send people to follow, and even some less important people need them to investigate.

Now, twenty-one hours have passed since Wang Lin's body was found.

The autopsy report from the medical examiner has also been issued.

The specific time of death of the deceased is that it must have been between 2 and 3 a.m. four days earlier.

There are no signs of being violated during his lifetime, but there are posthumous pinch marks on the doublets and private parts.

This point has aroused great attention from the task force.

Insulting the corpse after death, this presents the possibility of vendetta.

However, according to the detailed observation, there are pockmarked spots in the pinch marks, which indicates that the murderer committed violence through clothes.

So no fingerprints were found on the body of the deceased.

Survey Office.

"Master, the analysis of the three sets of footprints has been completed, and the physical characteristics of the owner have been basically determined."

Lu Chuan handed the final footprint analysis report to Liu Guodong, who had dark circles under his eyes, and lit a cigarette.

I haven't slept all night, and even Lu Chuan's body in his early twenties feels a little tired.

"Male, about 1.73 meters tall, weighing around 70 kilograms, and preliminarily judging his age to be between 28 and 33 years old."

"The other party should stand for a long time at work, and the bone seams of his feet are slightly larger than those of normal people."

"Cook?"

Yang Sen put two eye drops on himself and came over.

Lu Chuan shook his head: "It's not necessarily, it may also be a DJ or something, the specific situation can't be determined." ”

"Master, how is the fingerprint comparison?"

Hearing this, Liu Guodong's expression was a little solemn: "Seventy-two groups of fingerprints, we only successfully compare twelve groups." ”

This specific gravity probability......

It's not high, indeed.

Not only because the fingerprints collected are superimposed, but also because the handlebars of electric vehicles themselves are cylindrical.

Even if it is a single fingerprint, the fingerprint left on the cylinder is very distorted.

Fortunately, the handle is a smooth rubber sleeve, and the protrusions have been smoothed, otherwise, fingerprint collection would not be possible.

But even so, if you want to compare successfully, you need to preprocess the fingerprint, which is very difficult.

Lu Chuan learned the current survey, and he is very aware of the fingerprints collected on cylinders and irregular objects, and it takes superb skills to complete the analysis and comparison.

"How did it turn out?"

"Hehe, that's the interesting result."

Lao Bai also got up from the sofa and took the cigarette handed over by Lu Chuan: "Twelve sets of fingerprints, all of which are from the owner Wang Song." ”

Well?

"Twelve sets of fingerprints are all his?"

It's unlikely.

"Wang Song's electric car was stolen, and the fingerprints left on the top are most likely the thief."

"Of course, this thief may be the murderer of Wang Lin."

"Why are the twelve sets of fingerprints Wang Song's ......?"

Lu Chuan was slightly stunned, and suddenly understood something: "Wang Song...... Reporting a false case? ”

The results of the analysis of the field survey office were sent to Qin Yong very quickly.

Syllable!

Qin Yong, who also stayed up all night, looked at the analysis report of the current investigation office, and his eyes lit up.

"Arrest Wang Song immediately!"

Fingerprints are one thing, the key is the footprint analysis results made by Lu Chuan.

The physical characteristics of the owner of the shoe print on the pedal of the electric vehicle are consistent with Wang Song's posture.

With the results of the fingerprint comparison of the current survey, there is also the identification of the characteristics of the suspect by footprint analysis.

Wang Song quickly confessed the fact of killing Wang Lin.

And Wang Song's motive for committing the crime made the interrogating criminal police extremely surprised.

Wang Lin and Wang Song actually don't know each other.

The intersection of the lives of the two is a chat software.

"I didn't actually want to kill her." Wang Song in the interrogation room had already put on restraints and sat slumped in the interrogation chair.

"We had already negotiated the price, but she temporarily raised the price, and if the price did not increase, she threatened to tell my wife ......"

"I ...... Whining...... I really didn't mean to......"

Wang Song, who had a handful of snot and tears, explained the beginning and end of the meeting between the two.

In addition to leading the dance in the slow swing bar, Wang Lin also has other part-time jobs.

There are also a lot of men who need this on chat software.

Four days ago, the two negotiated a price of 500 yuan.

The agreed place is at Wang Song's hotel.

But after the two met, Wang Lin asked for a price increase of 1,000 yuan on the grounds that Wang Songchang was ugly.

also threatened Wang Song that if the price was not raised, she would come to the restaurant to make trouble and tell his wife about his bubbles.

Wang Song was in a hurry and strangled Wang Lin to death in the hotel.

"What's going on with Wang Lin's chest and the pinching marks on her lower body?"

This is the result of a forensic examination.

"This ...... After I strangled her, I wanted to ...... I wanted to be comfortable......"

"But...... I was afraid to leave evidence, so I put it through my clothes...... Through the clothes......"

Wang Lin's mobile phone, ID card and backpack were found in the back kitchen of Wang Song's restaurant.

As for the theft of the electric car, it is a play directed by Wang Song.

That night, he rode out of the electric car and then returned to the hotel.

The surveillance video of the car theft discovered by the traffic police was actually deliberately left by Wang Song.

He has lived in Beihu Road for more than 20 years and is very familiar with it, and it is clear where there is surveillance and where it is not.

After that, he returned to the hotel from the unmonitored path, took Wang Lin with him, and dragged him to the Happy Reservoir to throw the body.

"Ding!"

"Advanced mission completed: The host collected key fingerprint information on the electric vehicle where the crime occurred through a self-made fingerprint contrast agent, which helped the action team lock the scope of the suspect and solved the case of throwing corpses in the Happy Reservoir."

"System Reward: Intermediate Bone Identification Analysis Skill Card."

"Does the host claim the reward?"

Intermediate Bone Identification Analysis Skills?

Lu Chuan was slightly stunned.

The skills that the system rewards this time are a bit strange.

Bones, in general, are not encountered much.

But once it happens, it is likely to be a murder case transformed from a long-term disappearance.

Of course, there are also accidental deaths that result in people going missing, but this probability is relatively small.

Although it is a little strange why the system rewards this skill, it is a medium-level skill card.

Lu Chuan, who had already experienced the intermediate fingerprint collection skill card, knew that this was already an expert-level ability.

From the comparison of the situation that Lu Chuan understands, it should be the ability that only a type of person in the provincial department can have.

"Pick!"

Wow!

One by one, the information shuttled through Lu Chuan's consciousness.

Knowledge about the human skeleton flocked in.
