Because the murderer started committing the crime from the 11th, and started to soak in wet on the 15th.

From the evening of the 15th to the evening of the 17th, wet it continuously. During this period, if the chef commits the crime, his time for committing the crime cannot be guaranteed.

After all, most of the work of chefs starts from late in the morning.

There are people who get off work at around 10 o'clock in the evening, even 11 o'clock and 12 o'clock.

All, if he is a chef, he can only ask for leave and have time to commit the crime.

“There are 259 chefs in these 95 restaurants.”

"From the 11th to the 17th, there were 3 people who took leave in total, and 18 people who took leave intermittently."

“We conducted a detailed investigation of these people.”

Zhang Chaoyang changed a projection: "Three people who have never been around, two of them are seriously ill of their parents, and one of them is going to get married. They all returned to their hometown and are not in Anbei City."

"We have contacted the local detective team to verify this."

"The other 18 people, one person, the longest time to take three days off was a minor surgery in the hospital."

"For the other 17 people, most of the time to take leave is half a day, and there will be one day."

"However, after the investigation, there is basically no time to commit the crime."

Click.

"This is the freezer inspection record of 95 hotels."

“There are 175 freezers in total.”

"There are 158 in use, and there are no cleaning records in recent times."

"The technical department has tested its refrigerated residues and found no residues of Ruan Xiaoqing's blood or tissue residues."

Chen Yan nodded. Zhang Chaoyang's group had a lot of work, but the work was very meticulous.

If the body that had been installed by Ruan Xiaoqing in a cold storage was very likely to be cleaned after all the bodies were processed.

However, in ordinary hotels, no freezers can be washed once, from buying a freezer to using it or the hotel goes bankrupt.

“158 freezers…”

"Did you check the remaining 17 freezers?"

Zhang Chaoyang nodded: "We have checked them too."

"The earliest damage was one and a half months ago."

"I have verified it with the staff of the relevant hotel, and there is no doubt about it."

Zhang Chaoyang's group has the most people.

Liu Biao, captain of Anbei City Detective Team, assigned 50 people to Zhang Chaoyang and the others.

Only then did the hotel within three kilometers survey the two days.

However, now it seems that the possibility of hotel personnel committing crimes is basically ruled out.

“How is the slaughterhouse and the cold investigation?”

Zhang Chaoyang still shook his head: "The location of the Vocational and Technical College is close to the city center, and there is no slaughterhouse nearby."

"However, we checked the raw meat sales points in nearby farmers' markets."

"We still checked all raw meat sales outlets based on three kilometers."

“There are 6 outlets in total.”

"However, we conducted a survey on all the personnel in the outlets and frozen meat refrigerators."

"The same as the search results of the hotel, there are no doubts."

Zhang Chaoyang sighed and continued, "As for the cold storage, we have also conducted an investigation."

"Including supermarket cold storage, logistics station transit cold storage and a cold chain transit station two kilometers away."

“We all conducted an investigation and conducted sample inspections on the cold storage.”

"The cold chain transit station has standardized management, and there are cargo orders for entry and exit, which eliminates the suspicion."

"The cold storage of five large supermarkets has administrators, and they are only stored at low temperatures and cannot be refrigerated."

"There are also 7 logistics stations for transit, 7 freezers and 1 small cold storage."

“Not freezes.”

Zhang Chaoyang's investigation has been very detailed.

Three kilometers outside the school, all places where the corpses could be frozen and the corpses were basically investigated.

Now, the remaining and most important location survey is also the most important one.

Zhang Chaoyang has not reported yet.

And this is what Chen Yan cares most about.
