The situation that Qin Yong was most worried about did not appear.
There was no second body in the reservoir. What the salvage team fished out was an electric car.
This is the scope of current survey work.
Liu Guodong has already conducted a preliminary inspection of the electric vehicle.
"Team Qin, long hair was found in the rear wheel bearing of the electric vehicle."
Liu Guodong, who was wearing three layers of gloves, held a piece of hemp rope: "The hemp rope was found on the back seat of the electric car. It is probably a tool for binding the body."
"First tow the electric vehicle back to the detachment, and now we will conduct a detailed inspection here."
Faced with the electric vehicle that was likely to be a tool for throwing corpses, Qin Yong paid great attention to it.
"Ren Qiang, your team is conducting a search and platoon on the nearby villagers."
"Sun Jun, you are responsible for checking the surveillance cameras nearby. Pay special attention to the surveillance cameras from three days ago."
"yes!"
Sun Jun was the leader of the action team, and the two of them started working immediately after receiving the order.
Qin Yong frowned deeply and got in the car directly to report to the city bureau.
The corpse was buried in the reservoir, and at least three days had passed. Theoretically, the difficulty of solving the case was much greater than that of Zhang Wen's murder case.
Of course, the specific situation will depend on the interviews and surveys.
There are also many murder cases that are solved directly when the masses are involved.
After all, except for rare serial murder cases, it is difficult for anyone to gain experience in murder.
Just like Zhang Minlu who killed Zhang Wen.
Although the scene was cleaned up, the burned out cigarette butt still betrayed him.
According to Zhang Minlu's confession, he smoked while wiping the scene.
And I also thought that if the cigarette butt was left in the ashtray, it would become evidence.
So he just flicked the ashes into the ashtray and put the cigarette butts away himself.
But when he finished smoking his second cigarette, he threw the cigarette butt into the trash can.
A hundred secrets and a sparseness, this is ordinary people.
There is no leakage, they are all capable people.
In this society, the vast majority of people are ordinary people.
Just like the young masters in the club, most of them are good at hands or words.
If you are really talented, you may earn more by finding a job in a certain company.
Even if you don't make much money, most of the people you serve are of high quality.
Criminal Investigation Detachment.
Lu Chuan has completed the extraction of the DNA information of the deceased, and the fingerprint comparison has also been completed.
He is reporting to Liu Guodong who has just returned.
"The deceased's name is Wang Lin, female, native of Haizhou, 26 years old."
"Ding!"
"The basic task is completed: the host perfectly extracted the fingerprint information of the soaked corpse and completed the identification of the deceased."
By coincidence, the deceased had just applied for a new ID card last month, so the fingerprint information was left in the fingerprint system.
Liu Guodong was a little surprised that Lu Chuan confirmed the identity of the deceased so quickly.
"The fingerprints collected from soaked corpses will be somewhat swollen. Isn't it that easy for the system to compare?"
Liu Guodong has also been exposed to fingerprints soaked in corpses before.
This kind of fingerprint extraction is not difficult, but comparison is very difficult.
Because the corpse was swollen, the imprinted fingerprints swelled, which required a second adjustment of the fingerprints.
This process is not just about shrinking the fingerprint image as a whole.
This requires technology and even more experience.
Whether the comparison is successful depends on luck.
After this set, with the level of Liu Guodong and Yang Sen Laobai, it would take more than ten hours to complete it.
As a result, Lu Chuan finished it in less than two hours by himself?
After Yang Sen washed his hands, he came over and took the fingerprint identification report issued by Lu Chuan: "Ren Qiang asked you for help last time. Didn't you say you were not very good at fingerprint analysis..."
Um?
Yang Sen was slightly startled after receiving the report: "Your fingerprints..."
Liu Guodong also discovered the problem.
The fingerprints extracted by Lu Chuan had no expansion!
The fingerprints of soaked corpses did not swell!
"Xiao Lu! How did you do it?"
Lu Chuan didn't think it was anything. In the intermediate fingerprint collection skills, these were all small scenes.
"I used a hollow steel needle..."
Lu Chuan explained the process of collecting fingerprints: "The fingerprints collected in this way basically do not expand."
Liu Guodong and the other three looked at each other silently without speaking.
The dog beeped.
A handful of years are wasted.
However, getting a skill for free... is not bad.
I'm just a little embarrassed.
"Um...Xiaolu, after you finish working on this case, please give me a good meal."
"Yes, I'll pay for it!"
Liu Guodong took the fingerprint identification report with Lu Chuan's name on it and went directly to report to Qin Yong.
This time, regardless of whether the case is solved or not, the current investigation has made a small contribution.
Don’t underestimate the identification of the deceased.
In the vast majority of murder cases, the murderer has a certain motive for killing.
Whether it is love killing, vendetta or killing for money, a relatively large proportion of crimes are committed by acquaintances.
The case that detectives fear the most is murder of passion.
For example, a random stranger is killed on the street, and then the person runs away.
This is the hardest case to solve.
It's like a single man in the dark, passing by an alley and seeing a beautiful baby.
Who knows who this man was afterward?
Babies don't remember either, unless they are particularly gifted.
As long as the identity of the deceased is confirmed, the deceased's relationship network can be traced.
The possibility of finding the murderer is much greater.
In addition, it sounds good even when reporting to the superiors.
At least we know who the deceased is.
Otherwise, how to report?
So who?
Moreover, no one knew who died, so it would be strange to find the murderer.
The current survey office shows off its skills once again.
Liu Guodong, go and come back quickly.
"We only have one mission left."
In the yard, Liu Guodong and the other four stared at the electric car in front of them, spinning around and around.
"Where to start?"
Liu Guodong frowned.
Xingfu Reservoir is the scene where the body was dumped, and investigations in the surrounding areas have not found anything so far.
According to the examination results of the corpse, Liu Guodong had just been to the autopsy room.
The autopsy is in progress, but according to Wang Changjiang's preliminary judgment, the body can provide little information.
There are only causes and times of death.
Lu Chuan also inspected the surface of the body and found nothing major.
And this electric car, as a body transport tool that once transported the deceased, is the most likely place where the murderer left traces.
However, the electric car has been soaked in water for three days after all.
For such a long time, even if the murderer left fingerprints, there was no way to collect them.
"First, take out the hair that was stirred into the rear wheel bearing, extract the DNA information, and compare it with the DNA information of the deceased to confirm that this is the tool for transporting the body."
Lao Bai gave advice.
"Lu Chuan and I will conduct a visual inspection of the car body to see if we can find any fingerprints."
Yang Sen crossed his arms and stood next to the back seat of the electric car, watching carefully.
Liu Guodong nodded: "Follow this order first."
The four people worked together and began to investigate electric vehicles.
