Chapter 98 First Case Analysis Meeting
In the office of the Third Brigade, everyone was having a meeting.
This was the first case analysis meeting Zhou Yi had held since his rebirth.
During the previous 316 case, since the case was solved within 24 hours, there were basically no meetings and we were constantly following up on clues.
In addition to the personnel from the Third Brigade, the formal case analysis meeting also included technicians from the Technical Department responsible for on-site investigations and forensic medical examiners responsible for autopsies.
In addition, there is another team of people.
In principle, Team One is the main body of the Criminal Investigation Detachment, not because Team One is directly under the charge of the captain of the Criminal Investigation Detachment, but because Team One is responsible for all criminal cases. The anti-gangster cases of Team Two and the serious cases of Team Three are all transferred internally according to the nature of the cases.
At the same time, in principle, the members of Team 2 and Team 3 are all outstanding talents selected from Team 1.
There are two exceptions. One is Chen Yan. He graduated from the Public Security University with a high degree of education, which is rare in the police system of Hongcheng. In addition, his shooting performance is almost the best, so he was directly noticed by Wu Yongcheng and was admitted to the Third Brigade as an exception.
The other one is Zhou Yi.
Due to the staffing issues of Team 2 and Team 3 and limited manpower, most cases require the assistance of Team 1.
This is also one of the important reasons why the team attended the meeting.
Wu Yongcheng wrote a few words on the whiteboard in front of him: The 313 major dismemberment case.
Then he wrote down the names of the main people involved in the case, including Xu Jiaguang, Zhang Hui, and Zhang Yu.
Zhou Yi looked at the words "313 Major Dismemberment Case" and had an indescribable feeling.
These words represent another possibility, a very terrifying possibility.
That is, the truth behind some missing cases is actually homicide, like the case of Zhang Hui.
Zhou Yi didn't remember that there was any case involving Zhang Hui in Hongcheng's criminal case files in his previous life.
If there was, he would definitely remember it, after all, dismemberment cases are rare.
This means that in the previous life, Zhang Hui, who was chopped into pieces in the septic tank of Donghai Community, was not discovered by anyone until she completely rotted and decomposed and disappeared from this world.
He didn't know how many such disappearances there were, or how many victims had disappeared without even being known to anyone about their deaths.
He only knew that he had another responsibility on his shoulders.
Wu Yongcheng said: "I will not elaborate on the basic details of the case, everyone should know it."
"It's important to note that this case was originally being treated as a common missing persons case by the local police station. It was Zhou Yi's keen intuition and persistence that prevented such a serious crime from being overlooked. I hope everyone will learn from Zhou Yi and always maintain the keenness of a criminal police officer."
"Okay, enough with the official rhetoric, let's get started," Wu Yongcheng said self-deprecatingly. "First, let's talk about the on-site investigation."
Qiao Jiali stood up and said, "Alright, Captain Wu, let me first talk about the on-site investigation. The on-site investigation is mainly divided into two parts: one is the septic tank in Donghai Community, and the other is the home of Xu Jiaguang and Zhang Hui."
"We recovered a total of 54 pieces of human tissue from the septic tank. I'll have the forensic doctor provide more details on this later. I'll mainly discuss the condition of the septic tank."
"The septic tank in Donghai Community uses the commonly used urban septic tank structure, which has the function of treating and discharging feces and sewage. Simply put, solid particles and heavier suspended matter will sink to the bottom, forming a sludge layer; lighter suspended matter will be treated and discharged directly into the city's sewage system through the discharge pipe."
Qiao Jiali said solemnly, "In other words, the body parts found so far have sunk to the bottom of the sludge due to weight. Others have either completely decayed or been discharged directly into the city's sewage system, making the chances of finding them almost zero."
These few words made everyone present feel very heavy-hearted. Anyone who put themselves in the victim's shoes would find it unbearable.
"We've also confirmed with the Environmental Sanitation Bureau that unless there are special circumstances, the community's septic tank is usually cleaned every two years. The last time it was cleaned was last year, so there's no possibility that any body parts were mistakenly removed."
"Then we investigated the scene at Xu Jiaguang's home. We focused our investigation on the kitchen and bathroom, two possible locations where the body was dismembered. We ultimately identified the bathroom as the dismemberment site. Using luminol, we discovered a large amount of fluorescent reaction on the bathroom floor and walls."
"Wait." Wu Yongcheng suddenly raised his hand.
"Captain Wu, what's wrong?" Qiao Jiali asked.
Wu Yongcheng pointed at Zhou Yi and said, "Zhou Yi, you speak for yourself."
Zhou Yi nodded and told Wu Yongcheng what he had said before about the limitations of the luminol reagent.
After getting confirmation from the colleague in charge of the investigation in the technical department, Qiao Jiali said, "This is my fault. I didn't expect this when Zhou Yi and I went to Xu Jiaguang's house."
"No, it wasn't Sister Qiao's fault," Zhou Yi said. "I was the one who opened the bathroom door at Xu Jiaguang's house and saw the room full of feces. Xu Jiaguang immediately closed the door. Sister Qiao didn't see the specific scene, she just listened to my brief description."
Qiao Jiali gave Zhou Yi a grateful look.
Wu Yongcheng said, "Xiao Qiao, please continue."
"Okay. Based on the luminol reaction, we tried to find any remaining blood and extract a sample. Unfortunately, no blood sample was found. Now it seems that it was probably cleaned during dismemberment and later during feces removal, resulting in no blood remaining."
"We then searched other areas and found a kitchen knife, a meat cleaver and a fruit knife in the kitchen, all of which were taken back for further testing."
"Besides that, we also found a locked wooden box in Xu Jiaguang and Zhang Hui's room. After opening it, inside..." Qiao Jiali blushed slightly and said awkwardly, "Inside was a large amount of bedding, handcuffs, whips, candles, underwear, stockings, and so on, and some..."
"Forget it. Everything is filed away as evidence. You can look at the photos for yourselves."
Everyone was puzzled as to why Xiao Qiao couldn't speak clearly.
But when Zhou Yi took the photos from the embarrassed Chen Yan, he was stunned after looking at a few of them.
There are a lot of big, indescribable ones in there.
Zhou Yi immediately passed the photo to the person behind him.
Although we were police officers investigating a case, the social atmosphere in the 1990s was still very reserved. To be honest, if we wanted to buy this kind of thing, we wouldn't even know where to go.
Someone secretly cursed, "What a pervert."
Qiao Jiali cleared her throat. "Ahem, we also found a bundle of rope in this box. On the rope, we found traces of what appears to be blood and some unidentified liquid. The technical department is already identifying the components."
Zhou Yi immediately became alert: "Rope?"
