Chapter 28 Locking the Suspect
Conference Room No. 1.
After the whole night, everyone is 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 police officers 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 forensic doctor 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 raises the possibility of 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.
Now surveying the 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 clicked on it 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, weighing about 70 kilograms, tentatively estimated to be between 28 and 33 years old." The gap is slightly larger than that of a normal person.”
“Chef?”
Yang Sen put on two drops of eye drops 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?"
After hearing this, Liu Guodong's expression became solemn: "We only successfully compared twelve of the seventy-two sets of fingerprints."
This The probability of specific gravity...
It is indeed 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 fingerprints collected from cylinders and irregular objects require superb skills to complete analysis and comparison.
“What was 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."
Huh?
"All twelve sets of fingerprints are his?"
This is unlikely.
"Wang Song's electric car was stolen. The fingerprint left on the top is most likely that of the thief."
"Of course, this thief may be the murderer of Wang Lin."
"How come the twelve sets of fingerprints are all Wang Song's..."
Lu Chuan was slightly startled, and immediately thought about something: "Wang Song... reported a false case?"
Existing Investigation Office The analysis results were quickly handed to Qin Yong.
Snap!
Qin Yong, who 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 surprised the interrogating criminal police.
Wang Lin and Wang Song actually don’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 negotiated 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 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 is Wang Song’s hotel.
But after the two met, Wang Lin asked to increase the price to one thousand yuan because of Wang Song's ugly appearance.
She also threatened Wang Song that if the price was not raised, she would come to the restaurant to cause 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 chest 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 to...want to feel comfortable..."
"But...I was afraid of leaving evidence, so I just used my clothes... Through 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 homemade fingerprint developer to collect key fingerprint information on the electric vehicle where the crime occurred, helping the action team to locate the suspect and detect the case. The corpse dumping case in Xingfu Reservoir. "
"System reward: Intermediate skeleton identification 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 has already experienced the intermediate fingerprint collection skill card, knows that this is already an expert-level ability.
Compared with what I learned from Lu Chuan, it should be the ability of a type of person who is an expert in the provincial department.
“Get it!”
Wow!
One after another, messages shuttled through Lu Chuan's consciousness.
Influx of knowledge about human skeleton.
