"It takes ten minutes or even a few minutes after the body dies to be infested with fly parasite eggs."
Liu Guodong paused and explained.
Of course Qin Yong knew this, but he still asked. Liu Guodong naturally understood what he meant, and then said: "So, this is also an approximate time. The time when the deceased was killed should only be earlier than this, not later."
After all, if the murder occurred in a closed room and there were no flies in the room, there would be no parasite eggs.
So, don’t talk too much and leave some room.
"What suggestions do you have?"
This is a clue that Qin Yong never thought of.
Qin Yong has encountered this kind of case before when the body was frozen and then thawed.
Frozen corpses will contain a large amount of water residue in the muscle fibers, and traces of freezing can also be found during autopsy under the viscera.
However, no signs of freezing were found in the autopsy of the rotting corpses on the bank of Bailan River.
As for low-temperature refrigeration…
Never seen this kind of thing before.
"Our suggestion is to conduct a search of the cold storage surrounding the body where the body was found."
Liu Guodong's suggestion was discussed by several people in the current survey office.
Although Lu Chuan found traces of refrigeration on the body, it was not of any substantial help in solving the case.
However, if you want to refrigerate the entire body for more than 20 days, ordinary families will definitely not be able to do it.
"In the Happy Garden case three years ago, the murderer froze the body in a household freezer."
Qin Yong was deeply impressed by the case Liu Guodong mentioned.
The murderer was the victim's wife. Due to domestic violence, the victim's long-term gambling and other reasons, she was killed by the wife by mistake after her husband got drunk and had a conflict with his wife.
Later, the wife froze the body in a freezer, and no one found it for more than a year.
"Household freezers do not have a refrigeration function, and the murderer should have refrigerated the body for about twenty-five days."
"For such a long time, without professional equipment, the corpse would have rotted long ago."
"This is indeed a clue..."
"In this way, I will arrange for Ren Qiang and the others to conduct a focused investigation."
Sainty Logistics is a logistics company that has just emerged in Haizhou City in recent years.
The company only engages in cold chain logistics and transportation.
Compared with before, the development of cold chain logistics and transportation can be described as a blowout.
In the past, transporting frozen goods could only be done in winter.
In the south, because of the high temperatures and no sub-zero weather even in winter, the transportation of frozen goods has always been a problem.
Cold chain logistics and transportation came into being.
Shuntian Logistics' transit cold storage is right next to the Bailan River.
When Zhang Xiao was checking the surrounding residents, he had already visited this cold storage once, but he had not gone in to take a look.
Now, I received an order from Ren Qiang to conduct a detailed search of the twelve cold storages around Bailan River, so I came again.
"Officer Chen?"
The security guard at the gate is named Wang Zhi, who is in his fifties and is a nearby villager.
Chen Dong, a policeman from the nearby police station, has been cooperating with Zhang Xiao in the investigation these days.
"Old Wang, open the door. This time we want to search the cold storage here."
"search?"
Wang Zhi had no doubt that he was there, and he didn't want to see any search warrant.
The nearby villagers all farmed for a living when they were young, while the older ones have little education and only know a few words.
In recent years, due to the rapid development in the surrounding area, the land at home has been contracted by the village, and Wang Zhi no longer farms. Read the book La
Chen Dong's police uniform can be used with any certificate, not to mention that Wang Zhi's grandson has asked Chen Dong for help when applying for household registration.
The household registration policeman at the town police station is not easy to talk to, so it will be easier with Chen Dong's help.
"Well, the hair-dressing order must be checked in every cold storage."
"Oh, wait for me, I'll go inside to get the remote control."
In a few breaths, the railing was raised, and the two people's car drove into the cold storage compound.
"Lao Wang, does your cold storage have a cold snow area?"
Zhang Xiao has run three cold storages, two of which belong to logistics companies and one to a food factory.
However, these three cold storages only have freezer rooms and no low-temperature refrigeration rooms.
In this case, it would not be consistent with the clues found in 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 the same busy scene.
"Yes, yes, it was newly built last year, behind the large cold storage."
Um?
really have?
Zhang Xiao's spirit was slightly lifted.
There are fewer and fewer clues in the Bailanhe corpse case, and with the continuous overtime work for a week, the frontline criminal police involved in the case are very tired.
Wang Zhi's answer was the best news Zhang Xiao had heard in the past few days.
But Zhang Xiao did not go directly to Lengxue District impatiently.
Instead, he walked into the freezer door.
I just took a brief look last time, but I didn't go inside the cold place.
I just checked with Wang Zhi to find out the situation, and asked if there had been anything unusual recently, and if anyone had heard of anyone’s family missing.
This time, it’s time to check carefully.
"How many vehicles come in and out of this cold storage in a day?"
The cold storage of Shuntian Logistics was built three years ago and is relatively advanced.
The entire cold storage can accommodate large cold chain transport vehicles. Inside are the exits of the cold snow area, and workers are using forklifts to transport goods.
"Not necessarily, but there are at least 40 or 50 vehicles. In the summer, during the peak period, there are hundreds of vehicles delivering goods a day."
Wang Zhi built it from the cold storage, and he looked at the gate here. Many things were very familiar.
"Let's go inside and take a look."
"Okay, I'm going to report to the supervisor. I can't get in, and I don't have a coat here."
The temperature in the cold storage is below zero, so it is not allowed to wear single clothes inside.
Moreover, Wang Zhi is just a security guard who knows a lot, but he is not qualified to lead two policemen to search the entire cold storage.
After a while, a man with a crew cut came running over with a smile.
"Two comrades, police officers, I'm sorry, I'm so far away from you."
"This is our manager Li Biao."
"Manager Li, we are from the Haizhou City Criminal Investigation Detachment. We want to search the cold storage. This is the search warrant."
Chen Dong did not know Li Biao and showed his ID in a formal manner.
The other party didn't step forward to check, but just smiled more enthusiastically.
"It's okay, it's okay, don't worry, we will cooperate fully and have the right to cooperate!"
"Well, where do we start?"
"Check every cold storage room."
"Okay, who is that? Lao Wang, go get three coats from Xiao Sun. I will personally accompany the two police comrades."
The case of Bailanhe has been widely spread, and everyone working nearby has heard of it.
"Comrade police, come here...is this the case of the dead man by the river?"
"What, do you have a clue?"
Zhang Xiao looked very carefully, observing every storage compartment.
"No, no, no," Li Biao waved his hand hurriedly: "I'm just curious and asking."
