Four hours later.

Cloud City Bureau.

The on-site investigation has been completed and the body has been transported back to the city office.

Song Ting is doing a full autopsy on the body.

All samples of items brought back from the site are also being tested.

Results should be available soon.

Conference room.

The criminal investigation team gathered here, discussing the case while waiting for the report from the medical examiner.

The murder has just happened, and everything is unknown.

It is necessary to go through the existing clues, check and advance little by little.

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

But considering that the autopsy results did not even come out at the moment, it was too difficult for a strong man, so he gave up.

"Little boy."

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 half past six in the morning."

"Lu Xiumei, female, thirty-nine years old, is a nurse in Yuncheng No. 2 Hospital."

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

"On the same day, that is, at half past twelve o'clock at noon today, we received a call that two people were killed at the same time, and the method was to cut their throats."

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

Speaking of this, Wang Xiaotong opened the photos of the scene and continued: "The fingerprints and footprints extracted from the scene are only Dong Kang, Lu Xiumei and a child. "

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

"Moreover, there is a certain sense of counter-reconnaissance."

Picture changes.

It's a knife with residual blood.

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 the household fruit knife. "

"And the victim's home has one less knife set."

"Therefore, this fruit knife should belong to theirs."

The picture changes again.

It's a pair of gloves.

Wang Xiaotong said: "From the grass outside the window of the master bedroom, I found this pair of gloves. "

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

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

She stopped.

That's basically all we have so far.

After Wang Xiao's fairy tale voice fell, Li Xiangbin spoke: "Since it is a deliberate killing, the problem is much simpler. "

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

"Well, investigating the interpersonal 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 they will conduct thorough inspections through visits."

"As long as you find a grudge against the victim, report it immediately."

Everyone nodded in 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 wondered: "Wang Ze, what are you looking at?" "

Wang Ze retracted his gaze and said, "Oh, it's nothing, look at these gloves." "

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

Wang Ze said: "There are folds at the fingertips, and the gloves seem to be a little big. "

"Or that when the murderer kills, the position of the gloves is offset."

"It's okay, it's okay, Team Li, you continue, I'll listen."

Li Xiangbin was suspicious and felt that today's Wang Ze was not normal.

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

"If there are people who know each other well, check it too."

"Do you understand?"

Everyone: "Got it!" "

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

Brainstorming is the only way to find more directions for investigation.

Maybe.

A major clue was inadvertently discovered by a police officer.

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

Wang Xiaotong turned his head: "Huh? "

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

"Do you want to check if the thirteen residents have any criminal records?"

Wang Xiaotong said: "I'm about to start the screening, let's wait for the meeting." "

"Oh."

Bao Qu nodded in understanding.

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 is an unsolved case?" "

Wang Ze nodded: "So to speak." "

"Using the victim's clothes to calmly wipe the murder weapon is no longer something that normal people can do."

"It is necessary to suspect that the murderers are either experienced or have serious psychological problems."

"Or rather, both."

Hearing this, Li Xiangbin's expression became more serious, and said: "If other cases are involved, the nature will be even more serious." "

"Should... It's not a serial murder case, is it? "

He almost startled himself when the question came up.

Just cracked a serial case of instigating suicide.

Do you want to come back together?

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

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

Looking at countless eyes staring at him, the corners of 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 has just happened, and there are no clues.

Who can tell if this is a serial murder case?

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

It's Song Ting.

"The results are in."

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