Conference room one.
After an all-nighter, everyone was still busy.
When a murder occurs, being able to take a nap on a chair is a luxury for the police handling the case.
Of course, not only the criminal policemen of the criminal investigation detachment are busy at this time, but also the people at the grassroots police stations.
Starting yesterday morning, all persons closely related to the deceased must be investigated.
These tasks cannot be completed quickly by the criminal police of the criminal investigation detachment alone.
The grassroots police stations also need to send people to follow them, 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 should be between 2 and 3 midnight four days ago.
There were no signs of being violated during his lifetime, but there were post-mortem pinch marks on his breasts and private parts.
This point has attracted great attention from the task force.
Insulting the body after death creates the possibility of a vendetta.
However, based on detailed observation, the pinch marks had pockmarks, which indicated that the murderer committed violence through his clothes.
So no fingerprints were found on the body of the deceased.
The current 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.
After not sleeping all night, even Lu Chuan's body in his early twenties felt a little tired.
"Male, about 1.73 meters tall and weighing about 70 kilograms. His age is tentatively estimated to be between 28 and 33 years old."
"The other person has to stand for a long time when working, so the bone seams in his feet are slightly larger than normal people."
"chef?"
Yang Sen put two drops of eye drops on himself and came over.
Lu Chuan shook his head: "That's not necessarily true. It could be a DJ or something. The specific situation cannot be determined."
"Master, how's the fingerprint comparison going?"
Upon hearing this, Liu Guodong's expression became solemn: "Of the seventy-two sets of fingerprints, we only successfully compared twelve sets."
The probability of this proportion...
It's really not high.
Not only because the fingerprints collected are superimposed, but also because the electric bicycle handle itself is cylindrical.
Even for individual fingerprints, the fingerprints left on the cylinder are severely deformed.
Fortunately, the handle is made of smooth rubber and the bumps have been smoothed away. Otherwise, fingerprint collection would not be possible.
But even so, if you want to successfully compare, you must preprocess the fingerprints, which is very difficult.
Lu Chuan studied spot surveying and knew very well that analyzing and comparing fingerprints collected from cylinders and irregular objects required superb skills.
"what's the result?"
"Hey, what's interesting is this result."
Lao Bai also got up from the sofa and took the cigarette handed over by Lu Chuan: "Twelve sets of fingerprints, all of them belong to the car owner Wang Song."
Um?
"All twelve sets of fingerprints are his?"
This is unlikely.
"Wang Song's electric car was stolen. The fingerprint on the top is most likely that of the thief."
"Of course, this thief may be the murderer of Wang Lin."
"How come all twelve sets of fingerprints belong to Wang Song..."
Lu Chuan was slightly startled, and suddenly understood what he was talking about: "Wang Song...reported a false case?"
The analysis results from the current survey office were quickly handed to Qin Yong.
Snapped!
Qin Yong, who had also stayed up all night, looked at the analysis report from the current survey office, his eyes shining.
"Arrest Wang Song immediately!"
Fingerprints are one thing, but the key is the footprint analysis results made by Lu Chuan.
The physical characteristics of the owner 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 investigation and the identification of the suspect's characteristics through footprint analysis.
Wang Song quickly confessed the fact of killing Wang Lin.
Wang Song's motive for committing the crime shocked the interrogating police officers.
Wang Lin and Wang Song actually 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 sat slumped in the interrogation chair.
"We had already agreed on the price, but she temporarily raised the price. If she didn't increase the price, she threatened to tell my wife..."
"I...wuwu...I really didn't mean it..."
Wang Song, who had runny nose and burst into tears, explained the whole story of their meeting.
In addition to leading the dance at the Slow 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 agreed on a price of five hundred yuan.
The agreed place was Wang Song's hotel.
But after the two met, Wang Lin asked to increase the price to 1,000 yuan because of Wang Song's ugliness.
She also threatened Wang Song that if he didn't increase the price, she would come to the restaurant to make trouble and tell his wife about the incident.
In desperation, Wang Song strangled Wang Lin to death in the hotel.
"What's going on with Wang Lin's breasts and the pinch marks on her lower body?"
This is the result of the forensic examination.
"This...after I strangled her to death, I wanted...I wanted to feel comfortable..."
"But... I'm afraid of leaving evidence, just through my clothes... through my clothes..."
Wang Lin's mobile phone, ID card and backpack were found in the kitchen of Wang Song Hotel.
As for the electric car being stolen, it is a play directed by Wang Song.
That night, he rode his electric bike out and then returned to the hotel.
The car theft surveillance video discovered by the traffic police was actually left behind intentionally by Wang Song.
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, he returned to the hotel through an unmonitored path, took Wang Lin with him, and took her to the Xingfu Reservoir to dump her body.
"Ding!"
"Advanced mission completed: The host used a self-made fingerprint developer to collect key fingerprint information from the electric vehicle where the crime occurred, helping the action team to locate the suspect and detect the corpse dumping case in Xingfu Reservoir."
"System reward: Intermediate skeleton identification and analysis skill card."
"Does the host receive the reward?"
Intermediate skeletal identification and analysis skills?
Lu Chuan was slightly startled.
The skills the system rewards this time are a bit strange.
Generally speaking, there are not many skeletons encountered.
But once encountered, there is a high probability that it will be a long-term disappearance case transformed into a murder case.
Of course, there are also accidental deaths that cause people to go missing, but the probability is relatively small.
Although it is a bit strange why the system rewards this skill, it is at least an intermediate skill card.
Lu Chuan, who had already experienced the intermediate fingerprint collection skill card, knew that this was already an expert-level ability.
Based on what Lu Chuan learned, it should be the ability of someone who is an expert in the provincial department.
"receive!"
Wow!
Messages shuttled through Lu Chuan's consciousness.
Knowledge about the human skeleton is pouring in.
