"After the corpse dies, it can be infected with fly parasite eggs in ten minutes, or even a few minutes."

Liu Guodong paused and explained.

Of course Qin Yong knew this, but he still asked this, Liu Guodong naturally understood what he meant, and then said, "So, this is also the approximate time, and the time when the deceased will be killed should only be sooner, not later."

After all, if the murder is in a closed room, and there are no flies in the room, there will be no insect egg parasitism.

So, don't talk too much, leave a little leeway

"What do you suggest?"

This was a clue that Qin Yong had never thought of at all.

The corpse was frozen and then thawed, this kind of case Qin Yong had encountered before.

Frozen corpses contain a large amount of water residue in the muscle fibers, and freezing marks can also be found during the autopsy of internal organs.

However, the autopsy of the rotting corpses on the banks of the Bailan River found no traces of freezing.

As for low-temperature refrigeration......

I've never seen anything like this before.

"Our suggestion is to do a survey of the cold storage around where the body was found."

Liu Guodong's suggestion was discussed by several people in the current investigation office.

Although Lu Chuan found that the body had traces of refrigeration, this did not help him substantially to solve the case.

It's just that if you want to refrigerate the whole body for more than 20 days, ordinary families will definitely not be able to do it.

"In the case of Happy Garden three years ago, the murderer put the body in a household freezer to freeze."

Liu Guodong said that Qin Yong was very impressed.

The murderer was the victim's wife, who was killed by mistake after her husband was drunk and had a conflict with his wife because of domestic violence and the victim's long-term gambling.

Later, the wife froze the body in the freezer, and no one found it for more than a year.

"The freezer used at home has no refrigeration function, and the murderer should have refrigerated the body for about twenty-five days."

"For so long, without professional equipment, the corpse should have decomposed long ago."

"It's really a clue......

"In this way, I will arrange for Ren Qiang and them to focus on the investigation."

Sainty Logistics is a logistics company that has just risen in Haizhou in recent years.

As long as the company is engaged in cold chain logistics and transportation.

Compared with the past, the development of cold chain logistics and transportation can be described as a blowout.

In the past, the only way to transport frozen cargo was during the winter months.

In the south, because of the high temperature, even in winter, there is no sub-zero temperature, the transportation of frozen goods has always been a problem.

Cold chain logistics and transportation came into being.

The transit cold storage of Sainty Logistics is on the edge of the Bailan River.

When Zhang Xiao was checking the surrounding residents, he had already come to this cold storage once, but he didn't go in to see it.

Now, I received an order from Ren Qiang's side to conduct a detailed search of the twelve cold stores around the Bailan River, so here we go again.

"Officer Chen?"

The security guard at the gate was named Wang Zhi, who was in his fifties and a nearby villager.

Chen Dong, a police officer from a nearby police station, has been cooperating with Zhang Xiao in the past few days to do the investigation.

"Lao Wang, open the door, this time I want to search the cold storage here."

"Search?"

Wang Zhi did not doubt that he had him, and he did not want to see any search warrants.

The nearby villagers all farmed for a living when they were young, and the older ones had no education, so they knew a few words.

In the past few years, because of the rapid development of the surrounding area, the land of the family has been contracted in the village, and Wang Zhi is no longer farming and reading books

Chen Dong's police uniform is easy to use with any certificate, not to mention that Wang Zhi's grandson has a household registration or something, and he is looking for Chen Dong's help.

The household registration police at the police station in the town are not very easy to talk to, and it is easier to do it with Chen Dong's help.

"Well, the order to go to the hair, check every cold store."

"Oh, wait a minute, I'll go inside and get the remote."

After a few breaths, the railing was raised, and the car of the two drove into the cold storage compound.

"Lao Wang, do you have a cold snow area in your cold storage?"

Zhang Xiao has already run three cold storages, two of which are from a logistics company and one from a food factory.

However, all three cold stores only have freezer rooms, and there are no low-temperature freezer rooms.

In this case, it does not match the clues found on the current survey.

Vehicles are coming and going in front of the cold storage door, loading and unloading goods.

Zhang Xiao took a look, the last time he came, it was also this busy scene.

"Yes, it was newly built last year, behind the big cold storage."

Well?

Really?

Zhang Xiao's spirit was slightly uplifted.

There are fewer and fewer clues in the Bailanhe rotting corpse case, and the front-line criminal police involved in the case are very tired after working overtime for a week.

Wang Zhi's answer is the best news Zhang Xiao has heard in the past few days.

But Zhang Xiao didn't go directly to the cold snow area in a hurry.

Instead, he stepped into the door of the freezer.

I just took a look at it last time, and I didn't go in coldly.

I just learned about the situation with Wang Zhi, and asked if there was anything unusual recently, whether I heard of anyone's family missing, and so on.

This time, it's time for a detailed inspection.

"How many vehicles are coming in and out of this cold storage every day?"

This cold storage of Sainty Logistics was built three years ago and is relatively advanced.

The whole cold storage can accommodate large cold chain transport trucks in and out, and there are cold snow area exits inside, and workers are using forklifts to move goods.

"Not necessarily, but at least forty or fifty trucks, and in the summer, at peak times, hundreds of trucks a day are delivered."

Wang Zhi was built from the cold storage, and he looked at the gate here, and many things were very familiar.

"Let's go inside and have a look."

"Okay, I'll go and report to the class leader, I can't get in inside, and I don't have a coat here."

The temperature of the cold storage is below zero, and it is not okay to wear single clothes when you go in.

And Wang Zhi is just a security guard, he knows a lot of things, but he is not qualified to take two policemen to search the entire cold storage.

After a while, a flat-headed man trotted over with a smile.

"Two police comrades, I'm sorry, I'm sorry, I'm not welcome."

"This is our manager here, Li Biao."

"Manager Li, we are from the Haizhou City Criminal Investigation Detachment, and we want to search the cold storage, this is a search warrant."

Chen Dong didn't know Li Biao, and showed his documents on official business.

The other party didn't come forward to check, but just smiled more enthusiastically.

"It's okay, it's okay, don't worry, we fully cooperate, and the right to cooperate!"

"Well, where do we start?"

"Let's take a look at every cold storage room."

"Okay, who is that, Lao Wang, go to Xiao Sun to get three coats, and I will personally accompany the two police comrades."

The case of Bailanhe has spread very widely, and people who work in the neighborhood have heard about it.

"Comrade policeman, come here...... Isn't it the case of the dead man by the river?"

"What, you have a clue?"

Zhang Xiao looked very carefully, and carefully observed every storage compartment.

"No, no, no," Li Biao hurriedly waved his hand, "It's just curious to inquire."
