I'm in a mental hospital, Bai Fumei forces me to be her boyfriend

meeting room.

As she spoke, Song Ting handed the test report in her hand to Li Xiangbin.

Li Xiangbin took it but didn't look at it immediately.

"Propofol?"

"Diazepam?"

"what."

Song Ting explained:"Propofol is a powerful medical anesthetic, and diazepam is a sleeping pill we are familiar with. Hearing this

, Li Xiangbin was surprised:"Why did the murderer use two kinds of drugs?""

Song Ting said:"Propofol combined with diazepam will make the drug reach an extremely strong state."

"Generally, after insomnia patients take diazepam, it will take effect in ten minutes to half an hour."

"With the addition of propofol, this time will be shortened to less than five minutes."

"Moreover, it is a deep sleep and it is difficult to wake up."

"Unless there is persistent and high-intensity pain stimulation.

Li Xiangbin:"Does cutting one's throat count?"

Song Ting said:" It doesn't count.""

"A person whose throat is cut usually dies in about 20 seconds."

"In this case, the arteries and trachea of ​​the two deceased persons were cut accurately, and the time of death should be about ten seconds."

"Only one knife was used.

Li Xiangbin frowned:"In other words, he has a lot of experience in identifying the murderer?""

The killing method of cutting the throat is not common.

Criminals rarely choose it.

Even if they do choose to cut the throat, it is rare to kill them with one knife.

There have been cases in the past where the throat of the deceased was cut continuously by the murderer. Several times.

This was caused by his unskilled first time committing the crime.

In this case, the murderer's method of committing the crime is so clean and neat, and he does not look like an ordinary criminal.

Song Ting nodded:"Yes, it should not be the first time he commits a crime.."

After saying that, she glanced at Wang Ze.

Regarding this matter, Wang Ze had already made an inference at the scene before.

Li Xiangbin was silent for a while and said:"Have you found the source of drug intake? Song Ting said:"

I found it. It's in the food.""

"Specifically, it’s in the porridge"

"The drug was not only present in the porridge in the victim's bowl, but also in the entire pot in the kitchen. Hearing this

, Li Xiangbin was surprised:"The whole pot?" Why is the child okay?

Song Ting said:"Maybe the murderer committed the crime after the child left home.""

Li Xiangbin pondered for a moment, nodded and said:"Well, it seems that this is the only possibility."

"After the children finish eating, they leave home and go out to play"

"At this time, the murderer entered and drugged people to kill."

"In this case, the murderer and the victim must be very familiar with each other."

In the conference room, everyone nodded.

The murderer passed through the restaurant and entered the kitchen in a grand manner, and drugged him openly.

This shows that the murderer and the victim must have known each other.

Moreover, they were very familiar.

Bao Qu said:"The murderer should also know that the child will be there at any time. Back, that’s why I chose propofol plus diazepam to achieve maximum efficacy."

"The crime can be completed within ten minutes"

"Now there is a question"

"How did the murderer know when the child would leave?"

"Could it be that you have been waiting nearby?"

Li Xiangbin said:"They are all in the same unit. If you look out the window, you can see the situation downstairs."

"And you can also wait in the corridor."

"This is not a problem. Hearing this

, Bao Qu nodded:"That's true.""

Residents in a unit building cannot hide anything happening in their house.

At this time, Wang Ze asked:"Is the victim a permanent resident? Or did you move here later? Wang

Xiaotong operated the computer and said,"Let me take a look."

After a while, she replied:"I moved here later, about two years ago, and now I live in a newly purchased second-hand house."

Wang Ze:"Where did you live before?""

Wang Xiaotong said:"A community twenty kilometers away has now been moved to the city center."

"oh."

Wang Ze nodded and didn't say much. Moving from the suburbs to the city center is considered an improvement and relocation.

It's quite normal.

However, we still need to check.

Li Xiangbin looked at him and said,"Wang Ze, is there any problem?

Wang Zedao:"He was killed just two years after moving. It may be related to the motive of the murder.""

"Since it's one direction, I think it's necessary to check it out."

"For example, someone in the unit building knew the deceased two years ago."

"In this case, the suspicion is very high.

Li Xiangbin pondered for a moment and said,"How do you want to check?"

Wang Zedao:"How about I go to the community where the victim lived before and visit."

Li Xiangbin nodded:"Okay.""

"Are you alone? How about letting Haoyu follow you? Wang

Ze waved his hand:"No, no, the workload on your side is not small. After all, there are thirteen households."

Li Xiangbin did not insist and said:"Okay, let's do this first.""

"Everyone, get busy and don’t miss anything during the investigation."

"Especially property and relationship issues."

The proportion of homicides caused by money and emotional reasons is still relatively large.

Therefore, investigation should focus on

"yes!"

Everyone took the order and stood up and left one after another, ready to start working.

At this time, Wang Ze called out to Bao Qu.

Bao Qu turned around and walked over, saying:"What's wrong, Wang Ze.

Wang Zedao:"I want to see the results of the on-site trace inspection.""

"Oh, OK."

With that said, Bao Qu handed the documents in his hand to Wang Ze and left.

Looking at Wang Ze who was flipping through the documents, Li Xiangbin wondered:"There are only fingerprints and footprints of the victim at the scene. Is there anything that can be checked?"

Wang Ze turned to one of the pages.

This is the overall layout of all the footprints at the scene.

Facing Li Xiangbin's inquiry, he said:"Let's see if we can restore the situation before the crime."

The footprints at the scene represent the location where the victim walked before he was killed.

Although it is relatively messy, you may be able to find something.

Seeing this, Li Xiangbin did not interrupt and stood up and said:"Okay, I'll leave first."

"Call me anytime if you need anything. Wang Ze said without raising his head:"

Goodbye Captain Li.""
