In the conference room.
As she spoke, Song Ting handed the test report in her hand to Li Xiangbin.
Li Xiangbin took it but did not read it immediately.
"Propopent?"
"Diazepan?"
"What is it?"
Song Ting explained," Propopent is a powerful anesthetic for medical use. Diazepam is a sleeping pill that we are familiar with.”
"Why did the murderer use two drugs?" Li Xiangbin was surprised.”
"Propopent and Diazepan will make the drug reach an extremely strong state," Song Ting said.”
"Generally, after an insomniac patient obeys Diazepam, it will take effect in ten minutes to half an hour.”
"With the addition of the anesthetic, this time will be shortened to less than five minutes.”
"Moreover, it's a deep sleep, and it's very difficult to wake up.”
"Unless they are stimulated by continuous and intense pain.”
"Does cutting the throat count?"
"Not really," Song Ting said.
"A person whose throat is slit will usually die in about twenty seconds.”
"In this case, the arteries and windpipes of the two victims were accurately cut. The time of death should be about ten seconds.”
"Only one slash."
Li Xiangbin frowned." In other words, the murderer is very experienced?"”
Killing someone by cutting their throat was not common.
There were very few criminals who would choose.
Even if they chose to slit their throats, it was rare for them to be killed in one strike.
There had been cases in the past where the victim's throat had been slit several times by the murderer.
This was caused by his lack of proficiency in committing a crime for the first time.
In this case, the murderer's modus operandi was so straightforward that he did not look like an ordinary criminal.
"Yes, it shouldn't be the first time." Song Ting nodded.”
After saying that, she glanced at Wang Ze.
Regarding this matter, Wang Ze had already made a deduction at the scene.
"Have you found the source of the drug intake?" Li Xiangbin asked after a moment of silence.”
"Yes, it's in the food."”
"To be specific, it's in the porridge."
"It's not just the porridge in the victim's bowl that has drugs in it. The entire pot in the kitchen has them.”
"The whole pot?" Li Xiangbin was surprised. Why is that child fine?"
"It's possible that the murderer committed the crime after the child left home."”
Li Xiangbin pondered for a moment and nodded."Hmm, it seems like this is the only possibility.”
"After the child finishes eating, he will leave the house to play.”
"At this moment, the murderer entered and drugged him.”
"In that case, the murderer and the victim must be very familiar with each other.”
Everyone in the conference room nodded.
The murderer had entered the kitchen through the dining room and drugged her.
This meant that the murderer and the victim definitely knew each other.
Moreover, it was very familiar.
"The murderer should have known that the child would come back at any time, so he chose to use both Propopent and Diazepan to maximize the effects," Bao Qu said.”
"The crime can be completed within ten minutes.”
"There is a problem now."
"How did the murderer know when the child would leave?”
"Could it be that he has been waiting nearby?”
"We're all in the same unit," Li Xiangbin said."If you look out the window, you can see what's going on downstairs.”
"And you can also wait in the corridor.”
"This is not a problem."
Hearing this, Bao Qu nodded.”
It was impossible to hide any movements from the residents of a single apartment building.
"Is the victim a permanent resident?" Wang Ze asked. Or did you move here later?"
"Let me take a look." Wang Xiaotong operated the computer and said.”
After a while, she replied," I moved here about two years ago. I'm living in a newly bought second-hand house now."”
"Where did you live before?" Wang Ze asked.
"It's a community 20 kilometers away. It's considered to have moved to the city center now."”
"Oh."
Wang Ze nodded and did not say anything else.
Moving from the suburbs to the city center was considered an improvement.
It was normal.
However, he still had to investigate.
"Wang Ze, is there a problem?" Li Xiangbin asked.”
"He was killed two years after he moved. It might have something to do with the motive."”
"Since it's in the same direction, I think it's necessary to investigate.”
"For example, someone in the unit knew the deceased two years ago.”
"If that's the case, it's very suspicious.”
"How do you want to investigate?" Li Xiangbin pondered for a moment.”
"Why don't I go to the community where the victim lived before and pay a visit?" Wang Ze said.”
"Alright." Li Xiangbin nodded.
"Alone? Why don't you let Haoyu follow you?"
Wang Ze waved his hand." No need, no need. The workload on your side is not small. After all, there are 13 households.”
Li Xiangbin didn't insist." Alright," he said." That's it for now."”
"Everyone, get busy. Don't miss anything during the investigation.”
"Especially when it comes to money and relationships.”
Homicide cases caused by money and emotional reasons accounted for a relatively large proportion.
Therefore, they should focus on the investigation.
"Yes, sir!"
Everyone received the order and left one after another, ready to start work.
At this moment, Wang Ze called out to Bao Qu.
Bao Qu turned around and walked over.”
"I want to see the results of the trace examination at the scene," Wang Ze said.”
"Oh, sure."
Bao Qu handed the document to Wang Ze and left.
Looking at Wang Ze who was flipping through the documents, Li Xiangbin felt strange."There are only the victim's fingerprints and footprints at the scene. Is there anything we can check?”
Wang Ze flipped to one of the pages.
This was the overall layout of all the footprints at the scene.
Faced with Li Xiangbin's question, he said,"Let's see if we can restore the situation before the crime.”
The footprints at the scene represented the location where the victim had walked before he was killed.
Although it was messy, he might be able to find something.
Seeing this, Li Xiangbin did not disturb him. He stood up and said,"Alright, I'll leave first."
"Call me anytime if you need anything."
"Goodbye, Captain Li," Wang Ze said without looking up.”
