Chapter 575: Southern Suburb Funeral Home
Currently, there is no better way except to scan the videos one by one.
Only after obtaining the other party's appearance information, it is possible to carry out the next step of investigation, control and tracking.
Even a wanted notice.
“We still need to increase our efforts in monitoring and investigation here.”
After thinking for a moment, Li Donglin said: "The Tianzhou City Criminal Investigation Detachment has concentrated its maximum efforts to cooperate with the two of you in the surveillance video investigation."
"Expand the search scope, centering on the location where the suspect has appeared, within a three-kilometer range All surveillance inside must be scanned.”
This decision made by Li Donglin was also based on experience.
The suspect was able to deliberately avoid the surveillance video of the hot pot restaurant. Not only can it be judged that the other party is very cautious, but it can also be concluded that the other party is familiar with the environment of the hot pot restaurant.
In addition, the video outside the hot pot restaurant did not capture the faces of the three suspects, which means that the other suspects were relatively familiar with the environment around the hot pot restaurant.
At least know the shooting directions and angles of some obvious surveillance equipment.
Based on this, the three suspects are likely to live or settle near the hot pot restaurant.
Normally speaking, a person's environmental familiarity range is probably within two kilometers.
With the residential area as the center and the surrounding area radiating for two kilometers, it is basically the limit.
Because two kilometers is the limit that most people can explore on foot.
Beyond this distance, most people will choose other means of transportation.
For example, taking a bus, bicycle or driving.
Li Donglin expanded this range to three kilometers, which was already far beyond the range.
“The focus is on the hot pot restaurant, the self-service teller machine where the suspect withdraws money, and the victim’s home.”
“Radiate to the surroundings and check all the surveillance cameras that can be found, not even a single frame. It’s too late.”
Half a month has passed since the case. If the other party had escaped, he would have escaped long ago, so now is not the time to rush, but to expand the scope and conduct a detailed search.
When handling cases, time is exchanged for space and space is exchanged for time.
In the prime time after the incident in the early stages of handling the case, it would be best if we could trade space for time.
As long as there is any possibility of a breakthrough in a short period of time, then we must increase our manpower and implement the human sea tactic.
But like the case of family extermination, half a month has passed, so there is no need to rush into it. The point is to exchange time for space.
The most important thing is to work steadily, find clues about the other party, and lock down the identity of the suspect.
“Another point is that after the suspect had a conflict with the victim in the hot pot restaurant, he should have decided to retaliate.”
“So, the murderer must not have gone far after leaving the hot pot restaurant. Instead, they waited for the victim to come out of the hot pot restaurant and followed them to the victim's home."
"So we focused on checking the surveillance from the hot pot restaurant to the victim's home to see if we could find anything. ."
"Yes!"
……
Early the next morning.
Lu Chuan went directly to the Nanjiao Funeral Home in QZ City.
Compared with Tianzhou City, the QZ City Criminal Investigation Detachment is more than one step behind in terms of software and hardware.
The Tianzhou City Criminal Investigation Detachment Forensic Office has its own cold room, but the QZ City Administrative Detachment does not have one.
QZ City Nanjiao Funeral Home is a cooperative unit of the QZ City Criminal Investigation Detachment. All corpses of homicide cases are placed in the Nanjiao Funeral Home during the refrigeration stage.
"Captain Qin, why are you here in person?"
The person fighting Qin Hui was an old man who looked to be sixty or seventy years old.
"Old Zhao, why is Captain Qin not Captain Qin? If you call me that, I won't bring you wine."
As he said that, Qin Hui handed over the Erguotou in his hand. past.
"Okay, okay, you have to be a fool. You know I'm good at this."
The old man took the wine and smiled happily.
Wang Ruiqing explained softly next to Lu Chuan: "Zhao Feng, the old man at the funeral parlor, I have known Captain Qin since he was young." "I have been working here for more than forty years."
Lu Chuan was stunned. No wonder Qin Hui brought wine with him. He turned out to be an old friend for decades.
"Is this the new guy?"
Old Zhao and Wang Ruiqing have known each other for a long time, but seeing how young Lu Chuan was, they thought he was a new criminal police officer from the QZ City Criminal Investigation Detachment.
"What's new, Lao Zhao, let me introduce you. This is Lu Chuan, the current detective of our Haizhou City Criminal Investigation Detachment, and a member of our provincial crime team!"
< br>“First-class individual merit three times!”
Oops!
Lao Zhao raised his eyebrows.
It’s useless if I don’t mention the previous title.
But three first-class individual merits...
"Hello, Officer Lu, my name is Zhao Feng, you can just call me Lao Zhao."
"The body is ready , right inside.”
After Lu Chuan thanked him, he followed Lao Zhao into the freezer.
The body has been lifted onto the stainless steel table.
After a night of natural thawing, it has softened, but it has not completely thawed.
It's still a bit difficult to open the arms and legs.
“Both the two deceased died of suffocation. One was mechanically suffocated by strangulation, and the other was suffocated by covering his face with a pillow.”
Lu Chuan stepped forward and inspected it carefully, and the conclusion was consistent with Wang Ruiqing's.
The victim, who was about 1.7 meters tall, had obvious semicircular bruises on his neck. It was obvious that he died after being pinched with both hands.
The other victim, who was about 1.6 meters tall, had no pinch marks on his neck, but there were minor friction wounds on his face, especially on his lips, mouth and nose, where there were forced friction wounds.
It was proved that he was suffocated to death by a pillow.
In addition, there were not many other injuries on the surface of the two corpses.
This shows that the deceased did not resist violently during the violation.
“After the incident, we detected ether in the mouth and nose of the deceased. The murderer probably entered the dormitory and stun six people with ether while the students were drunk and asleep, and then committed the atrocities.”< br>
Wang Ruiqing explained to Lu Chuan from the side.
Lu Chuan already knew this information in advance.
He had no doubts about it either.
This time the next time the body is inspected, Lu Chuan will focus on other parts.
Opening the legs of one of the corpses, Lu Chuan carefully inspected the private parts.
“There are no semen spots. The other party is using silicone condoms, which can be bought anywhere on the market.”
“At that time, we conducted an investigation on the pharmacies and supermarkets selling condoms around the school. But no clues were found.”
“Have you done any trace testing?”
"No, nothing was found except some blood stains and the victim's body fluids."
"We carefully inspected the private parts of the six victims and found no body hair of the murderer."
Without body hair, there is no way to identify a suspect through DNA testing.
Of course Lu Chuan knew this.
For such a big case back then, the investigators would have been very careful when doing the autopsy, so Lu Chuan did not think that he would definitely be able to find things that others had not found.
And this is not the purpose of his coming here this time.
However, regarding the situation of the case...
Lu Chuan already has some guesses.
"Captain Qin, it's almost done here. Can we meet the surviving student in the morning?"
