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

Chapter 575 Southern Suburb Funeral Home

At present, there is actually no better way, the only way is to scan the videos one by one.

Only after obtaining the other party's appearance information can it be possible to proceed with the next step of investigation, deployment, control and tracking.

Even a wanted notice.

"We still need to intensify the 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 you two in the surveillance video investigation."

"Expand the search scope, center on the location where the suspect has appeared, and scan all surveillance within a three-kilometer radius."

The decision Li Donglin made 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 shows that the 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 inference, the three suspects are likely to live near the hot pot restaurant or settle nearby.

Normally, a person's environmental familiarity range is probably within two kilometers.

Taking the residential area as the center and radiating two kilometers around it is basically the limit.

Because two kilometers is the limit of what most people can explore on foot.

Beyond this distance, most people will choose other means of transportation.

Such as public transport, bicycle or driving.

Li Donglin expanded this range to three kilometers, which was already far beyond the range.

"The focus is on hot pot restaurants, automatic teller machines where the suspects withdraw money, and the victim's home."

"Radiate around, check all the surveillance cameras you can find, and pass without missing a single frame."

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 a case, it would be best if you 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 manpower and implement the human sea tactic.

But like the case of massacre, 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 opponent, and lock down the identity of the suspect.

"Another point is that the suspect should have decided to retaliate after the conflict with the victim at the hot pot restaurant."

"So, the murderer must not have gone far after leaving the hot pot restaurant. Instead, he waited for the victim to come out of the hot pot restaurant and followed them to the victim's home."

"So we will focus on checking the surveillance from the hot pot restaurant to the victim's home to see if we can find anything."

"Yes!"

……

Early the next morning.

Lu Chuan went directly to the funeral parlor in the southern suburbs of QZ City.

Compared with Tianzhou City, the QZ City Criminal Investigation Detachment is far behind the other party 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 playing tricks with Qin Hui was an old man who looked to be in his sixties or seventies.

"Old Zhao, why is Captain Qin not Captain Qin? If you call me that, I won't bring you wine."

With that said, Qin Hui handed over the Erguotou in his hand.

"Okay, okay, if you want to say it, 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 of 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 new here?"

Lao Zhao and Wang Ruiqing had known each other for a long time, but seeing Lu Chuan's appearance and how young he was, he 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 active detective of our Haizhou City Criminal Investigation Detachment. He is also a member of our provincial serious crime team!"

"Three first-class individual merits!"

Hey!

Lao Zhao raised his eyebrows.

It’s useless not to mention the previous title.

But three times I received first-class individual merit...

"Hello, Officer Lu, my name is Zhao Feng, you can just call me Lao Zhao."

"The body has been prepared and is inside."

After Lu Chuan thanked him, he followed Lao Zhao into the freezer.

The body had 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 of 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, also 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 injuries on his face, especially on his lips, mouth and nose, where there were forced friction injuries.

It was proved that he was smothered to death by a pillow.

In addition, there were not many other injuries on the surface of the two bodies.

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."

Wang Ruiqing explained to Lu Chuan on 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.

Lu Chuan opened the legs of one of the corpses and carefully inspected the private parts.

"There are no semen spots. The other party uses silicone condoms, which can be purchased anywhere on the market."

"At that time, we checked all the pharmacies and supermarkets selling condoms around the school, but we found no clues."

"Have you done micro-testing?"

"No, nothing was found except for some blood stains and the victim's body fluids."

"We carefully examined 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 during the autopsy, so Lu Chuan did not think that he would be able to find things that others had not found.

And this is not the purpose of his coming here this time.

However, as to the circumstances of the case…

Lu Chuan already had some guesses.

"Captain Qin, it's almost done here. Can we meet the surviving student in the morning?"
