In a mental hospital, Bai Fumei forced me to be her boyfriend

Li Xiangbin originally wanted to ask Wang Ze if he could make a portrait based on the current clues.

But considering that even the results of the autopsy have not come out at this moment, it is too difficult, so he gave up.

"Children."

Li Xiangbin looked at Wang Xiaotong.

Wang Xiaotong nodded and projected the computer screen on the big screen.

"The identity of the deceased has been established."

"Dong Kang, male, 41 years old, is a taxi driver by profession."

"Dong Kang ran the night shift last night, and it didn't end until 06:30 in the morning."

"Lu Xiumei, female, 39 years old, is a nurse at Yuncheng Second Hospital."

"Coincidentally, I was also on the night shift last night and got off work at seven in the morning."

"On the same day, that is, at 12:30 noon today, we received a report that two people were killed at the same time by cutting their throats."

"As a result of the on-site inspection, no trace of a third party was found."

Speaking of this, Wang Xiaotong opened the photo of the scene and continued: "The fingerprints and footprints taken at the scene are only those of Dong Kang, Lu Xiumei and a child."

"It should be certain that the murderer is premeditated and has made sufficient preparations in advance."

"And, have a certain awareness of anti-reconnaissance."

The screen changes.

It was a knife with blood on it.

Wang Xiaotong said: "Forensic doctor Song said that according to the size and depth of the wound, it can be determined that this is the murder weapon, which belongs to a household fruit knife."

"The knife set in the victim's home is missing one."

"So this fruit knife should belong to their family."

The screen changes again.

It's a pair of gloves.

Wang Xiaotong said: "I found these gloves in the grass outside the window of the master bedroom."

"The preliminary judgment is that it was left behind by the murderer."

"The specific results will have to wait for the blood test report."

She stopped talking.

That's basically what I have so far.

After Wang Xiaotong's voice fell, Li Xiangbin said: "Since it is a deliberate murder, the problem is much simpler."

"Also, we have locked down the scope of the murderer."

"Then, investigating the relationship between the victim and the residents of the entire unit building is the focus now."

"From now on, every two people will be in charge of one household, and a thorough investigation will be conducted through visits."

"As long as you find any enmity with the victim, report it immediately."

Everyone nodded, expressing their understanding.

After speaking, Li Xiangbin turned his head to look at Wang Ze, and found that the latter was staring at the big screen.

He was surprised: "Wang Ze, what are you looking at?"

Wang Ze withdrew his gaze and said, "Oh nothing, look at these gloves."

Li Xiangbin looked back at the photo and said, "What's wrong with the gloves?"

Wang Ze said: "There are wrinkles at the fingertips, and the gloves seem a bit big."

"Or when the murderer kills, the position of the glove is shifted."

"It's okay, Captain Li, you continue, I'm listening."

Li Xiangbin was suspicious, feeling that Wang Ze was not normal today.

He didn't think much about it, and continued: "The scope of the investigation should not be limited to the victim and the residents of the unit building."

"If there are people who are acquainted with each other, we should also check."

"Do you understand everything?"

Everyone: "Understood!"

Li Xiangbin nodded: "Okay, now if you have anything to say, you can say it."

Only by brainstorming can we find more directions for investigation.

perhaps.

The important clue was discovered by a certain policeman inadvertently.

At this time, Bao Qu said: "Little boy."

Wang Xiaotong turned his head: "Huh?"

Bao Qu: "Didn't Wang Ze say that the murderer is probably not the first time to commit a crime?"

"Do you want to check whether the residents of the thirteen households have criminal records?"

Wang Xiaotong said: "I'm preparing to start screening, wait until the meeting is over."

"Oh."

Bao Qu nodded to show understanding.

When mentioning this matter, Li Xiangbin looked at Wang Ze and said, "Wang Ze, if the information of the thirteen households is normal, does it mean that there are unsolved cases left?"

Wang Ze nodded: "You can say that."

"Using the victim's clothes to calmly wipe the murder weapon is beyond what normal people can do."

"We have to suspect that the murderer is either experienced or has relatively serious psychological problems."

"Or rather, both."

Hearing this, Li Xiangbin looked a little more serious, and said: "If other cases are involved, the nature will be even more serious."

"Shouldn't it be a serial murder case?"

When this question was thrown out, he almost startled himself.

Just broke a serial abetting suicide case.

Is it possible to come together again?

Li Xiangbin's words also made the other members of the criminal investigation team look condensed.

The next moment, by coincidence, everyone turned their attention to Wang Ze.

Seeing countless eyes staring at him, Wang Ze's eyes trembled, and he spread his hands and said, "Don't look at me, I don't know."

I really think of him as a god.

The case just happened, and there are no clues.

Who can tell if this is a serial murder case?

At this time, someone pushed the door and walked in.

It's Song Ting.

"The result is out."

"In the stomach of the deceased, there was a large amount of propofol and diazepam."

.......

Chapter 46 Full investigation

meeting room.

While talking, Song Ting handed the test report to Li Xiangbin.

Li Xiangbin took it, but didn't look at it right away.

"Propofol?"

"Diazepam?"

"what."

Song Ting explained: "Propofol is a powerful medical anesthetic, and diazepam is a well-known sleeping pill."

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 medicine reach an extremely strong state."

"Generally, after insomnia patients take diazepam, it will take effect within 10 minutes to half an hour."

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

"Moreover, it's a deep sleep, and it's hard to wake up."

"Unless there is a persistent and intense painful stimulus."

Li Xiangbin: "Does cutting your throat count?"

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

"People whose throats are cut usually die in about 20 seconds."

"As far as this case is concerned, the arteries and trachea of ​​the two deceased were accurately severed, and the time of death should be around ten seconds."

"It only took one knife."

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

Cutting the throat is an uncommon way of killing people.

Rarely will criminals choose.

Even if you really choose to cut your throat, you can rarely achieve a one-shot death.

There have been cases before where the throat of the deceased was cut several times by the murderer.

This is caused by the unskilledness of committing the crime for the first time.

In this current case, the murderer's modus operandi is so straightforward, it doesn't look like an ordinary criminal.

Song Ting nodded: "Yes, it should not be the first crime."

After finishing speaking, 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 out the source of the drug intake?"

Song Ting said: "I found it, it's in the diet."

"Specifically, it's in the porridge."

"Not only the porridge in the victim's bowl contained drugs, but the whole pot in the kitchen."

Hearing this, Li Xiangbin was surprised: "There is a 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 while, nodded and said: "Well, it seems that there is only one possibility."

"After the child has finished eating, leave the house and go out to play."

"At this time, the murderer enters and prescribes drugs to kill."

"If that's the case, the murderer and the victim must be very familiar."

In the conference room, everyone nodded.

The murderer entered the kitchen grandiosely through the dining room, and then prescribed the drug grandiosely.
