Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 28 Lock down the suspect

Conference room one.

After all night, everyone is still busy.

In the event of a homicide, 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 in the grassroots police station.

Starting from yesterday morning, all personnel who were closely related to the deceased must be screened.

It is impossible for the criminal police of the criminal investigation detachment to complete these tasks quickly.

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

Now, 21 hours have passed since the discovery of Wang Lin's body.

The autopsy report from the forensic doctor has also been issued.

The specific time of death of the deceased should have been between 2:3 and [-]:[-] midnight four days ago.

There were no traces of being violated during his lifetime, but there were pinch marks on Shuangfeng and private parts after death.

This has aroused the special attention of the task force.

Insult the corpse after death, which creates the possibility of vendetta.

However, according to the detailed observation, there are hemp spots in the pinch mark, which shows that the murderer committed violence through the clothes.

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

Surveying the office now.

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

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

After not sleeping all night, even Lu Chuan's body in his early 20s felt a little tired.

"Male, about 1.7 meters tall, weighing around 28 kilograms, and preliminarily judged to be between 33 and [-] years old."

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

"chef?"

Yang Sen dripped two drops of eye drops on himself, and came over.

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

"Master, how is the fingerprint comparison going?"

Hearing this, Liu Guodong's expression was a little dignified: "There are 72 sets of fingerprints, and we only successfully compared twelve sets."

This proportion probability...

It's really not high.

Not only because the collected fingerprints are superimposed, but also because the electric handlebar itself is cylindrical.

Even if it is a single fingerprint, the deformation of the fingerprint left on the cylinder is very serious.

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

But even so, it is very difficult to preprocess the fingerprints if the comparison is to be successful.

Lu Chuan is a student of spot surveying, and he is very clear about the fingerprints collected on cylinders and irregular objects. It requires superb technology to complete the analysis and comparison.

"what's the result?"

"Hey, the interesting thing is this result."

Lao Bai also got up from the sofa, and took the cigarette handed over by Lu Chuan: "The twelve sets of fingerprints all belong to the owner of the car, Wang Song."

Ok?
"All twelve sets of fingerprints belong to him?"

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 one who killed Wang Lin."

"How come the twelve sets of fingerprints belong to Wang Song..."

Lu Chuan was slightly taken aback, and immediately thought of something: "Wang Song...reported a false case?"

The analysis results of the current survey office were quickly delivered to Qin Yong.

Snapped!
Qin Yong, who also stayed up all night, looked at the analysis report of the survey office, his eyes lit up.

"Arrest Wang Song immediately!"

Fingerprints are one aspect, but the key is the result of the footprint analysis made by Lu Chuan.

The owner's physical characteristics of the shoe prints on the pedals of the electric vehicle are consistent with Wang Song's.

With the fingerprint comparison results of the current survey, and the identification of the suspect's characteristics by footprint analysis.

Wang Song quickly confessed the fact of killing Wang Lin.

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

Wang Lin and Wang Song didn't know each other.

The intersection of their lives is a chat software.

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

"We had already negotiated the price, but she raised the price temporarily, and threatened to tell my wife if she didn't raise the price..."

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

With snot and tears, Wang Song explained the whole story of their meeting.

Apart from leading dancers at Slow Shake Bar, Wang Lin also has other part-time jobs.

There are also many men who need this on the 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 demanded that the price be raised to 1000 yuan on the grounds that Wang Songchang was ugly.

He also threatened Wang Song that if he didn't raise the price, she would come to the restaurant and tell his wife about his affair.

In desperation, Wang Song strangled Wang Lin to death in the restaurant.

"What happened to Wang Lin's chest and the pinch marks on her lower body?"

This is the result of the forensic examination.

"This...after I strangled her, I wanted...I wanted to feel better..."

"But... I'm afraid of leaving evidence, so I'm going through my clothes... through my clothes..."

Wang Lin's mobile phone, ID card and carry-on backpack were found in the back kitchen of Wangsong Hotel.

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

That night, after he rode his electric bike out, he returned to the hotel.

The car theft surveillance video found by the traffic police was actually left behind by Wang Song on purpose.

He has lived on Beihu Road for more than 20 years and is very familiar with it. He knows exactly where there is surveillance and where there is no surveillance.

Afterwards, they returned to the hotel from the unmonitored path, took Wang Lin with them, and dragged her to Xingfu Reservoir to dump her body.

"Ding!"

"Advanced task completed: The host collected key fingerprint information on the electric car where the crime occurred through self-made fingerprint developer, helped the action team to locate the range of suspects, and solved the Xingfu Reservoir dumping case."

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

"Does the host receive the reward?"

Intermediate skeleton identification and analysis skills?
Lu Chuan was slightly taken aback.

The skills rewarded by the system this time are a bit strange.

Generally speaking, there are not many skeletons encountered.

But once encountered, there is a high probability that the long-term disappearance has turned into a murder.

Of course, there are also accidental deaths that lead to missing people, but the probability of this is relatively small.

Although it is a little strange why the system rewards this skill, it is an intermediate skill card anyway.

Lu Chuan, who has already experienced the intermediate-level fingerprint collection skill card, knows that this is already an expert-level ability.

From what Lu Chuan learned, it should be the ability of a type of person who is a powerful expert in the provincial department.

"receive!"

Whoa!
Message after message shuttled through Lu Chuan's consciousness.

Knowledge about the human skeleton floods in.
