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

Wang Ze nodded: "Okay, thank you, I'll just ask these questions."

Liang Zhi smiled: "You're welcome."

After speaking, he looked at Pei Donglei.

Pei Donglei said: "You go back first, and I'll call you when I need something."

"Ok."

Liang Zhi nodded and stood up, leaving the office.

After Liang Zhi left, Pang Qun asked, "Have there been many such inexplicable fires outside the city?"

Pei Donglei said: "Not many."

"You said yes to natural fire."

"The probability of natural fires is still relatively low."

"The cause is nothing more than a lightning strike and a chemical reaction to spontaneously ignite."

"Captain Wang should know this, right?"

Wang Ze was thinking about something, when he heard the words, he said, "I know."

"Poor ventilation of cotton, peat, coal piles, etc., as well as nitrocellulose, ferrous sulfide, yellow phosphorus, phosphine, etc., are all prone to spontaneous combustion and fire."

"Also, some substances such as potassium, sodium, lithium, calcium, etc. are also prone to fire when in contact with water."

"Cotton and straw are in contact with concentrated nitric acid, the same."

"Certain chemical products, such as potassium permanganate mixed with glycerin, will immediately catch fire."

"There are many situations."

Pei Donglei looked at Wang Ze appreciatively, and said with a smile, "That's right."

"Therefore, we must take corresponding fire prevention measures according to the characteristics of these substances."

"Don't think that firefighting is easy to do, haha."

Pang Qun also said with a smile: "Hearing what you said, it's really complicated."

After speaking, he glanced at Wang Ze and was surprised.

The theoretical knowledge that the other party understands is also too much.

A bit beyond his acceptable range.

so young.

Where did you learn it?

Is there enough time?

You can't learn from birth.

At this time, Pei Donglei asked: "Captain Wang, is this matter related to the case? Is it important?"

Wang Ze replied: "I don't know yet."

"The case is now in the stage of comprehensive investigation, and any related incidents cannot be let go."

"Maybe it's related."

5.4 "Maybe irrelevant."

Pei Donglei smiled and nodded: "I understand."

Although he is not a criminal police officer.

But have you never eaten pork, haven't you seen a pig run?

Check countless clues.

Perhaps there is only one clue, useful to the case.

Very normal.

And it’s not always possible to find out.

Otherwise, there would be no unsolved cases in the world.

But after getting to know Wang Ze gradually, he suddenly felt that.

Others don't know, but I'm afraid in the hands of this young man, it should be difficult to have an unsolved case, right?

"Then, shall we go first?"

Wang Ze looked at Pang Qun.

Pang Qun nodded and said, "Captain Pei, excuse me."

Pei Donglei: "They're all our own people, so you're welcome."

Chapter 197 Wang Ze's Deduction [2]

Fire brigade door.

Pang Qun handed Wang Ze a cigarette.

Wang Ze took the ignition and took a deep breath.

"The bus line is basically checked."

he opened his mouth.

Pang Qun nodded: "That's right, the investigation has been done very carefully."

"It doesn't make much sense to look further down."

Wang Ze took a puff of cigarette and said, "I only know the identity of one deceased person, so it's really difficult to find out."

"I felt the need to add another line."

"Work hard on the other two dead."

Pang Qun turned his head: "What do you mean?"

Wang Zedao: "How was the process when the missing persons were investigated?"

Pang Qun said: "The workload is quite heavy, and a lot of people have been transferred."

"Xicheng is a place with a large permanent population and a large floating population, as well as black households."

"It is very difficult to determine the identity of the deceased through the investigation of missing persons."

"Moreover, it also includes missing persons who did not report."

Wang Ze said: "Did you exclude some people?"

"The number of missing persons every 27 years is indeed a lot, but most of them can be ruled out."

"For example, mentally handicapped people, children."

"I think the murderer committed such a deliberate crime, so the person who killed the disabled should not be?"

Pang Qun remained silent for a while, and said, "I couldn't judge the murderer's motive at the time, so I didn't think too much about it."

"I just want to quickly determine the identity of the deceased."

"you know too."

"How important is the identity of the deceased to the case."

Wang Ze nodded: "I know."

Pang Qun: "You said just now that the mentally handicapped and children are excluded."

"What about the old man and the bum and all that?"

Wang Ze: "That cannot be ruled out."

"The elderly and homeless people may also be among the targets of the crime."

"Captain Pang, when the missing persons were investigated, there was really no one in contact with Yuan Shengqiang?"

Pang Qun nodded helplessly: "Yes."

"After the No.2 deceased appeared two years ago, I compared them."

"This time, I also checked."

"But I didn't find anyone who knew or had an intersection with Yuan Shengqiang."

"You mean evil or evil?"

"Therefore, the possibility of random killing cannot be ruled out."

Wang Ze slowly exhaled a puff of smoke and said, "Then what if the missing person didn't report it?"

Pang Qun was surprised: "Didn't report the crime? Shouldn't it?"

Wang Ze said: "In this world, there are too many people who have no children, no father, no mother, and no spouse."

"And even if there are relatives, there is no guarantee that they will report the crime 100% of the time."

"There is no possibility of reporting the crime, but there is still."

Pang Qun frowned: "If this is the case, wouldn't it be more difficult to check?"

Wang Ze nodded: "Difficult to investigate is difficult to investigate."

"However, it is good to have corresponding missing person information. If not, we can analyze it and why not."

"There is a premise before the analysis, the victim is a normal person with a normal job."

"First of all, does the missing person have parents?"

"The children are missing, don't they call the police?"

"Probably not."

"As for the small probability, such as cutting off relationship with parents, or not contacting for a long time, don't worry about it."

"Secondly, does the missing person have a spouse?"

"It's hard to judge."

"Regardless of whether there is a spouse or not, it is within an acceptable range that no one has reported to the police for two years of disappearance."

"Because the possibility of conflicts in the long-term separation cannot be ruled out."

"Finally, does the missing person have any children?"

"This is the same as whether you have parents or not. There is a high probability that you don't have any."

"Then, we can make a general guess about the basic characteristics of the victim."

"The first point is that if you have no father and no mother, then you have to be older, at least 40 or even 50 years old."

"Let's not talk about those who are young and lose their parents."

"Second point, spouse and children."

"The victim's occupation should be a relatively unpopular one that few people do."

"Importantly, the relationship is poor, and it can be described as lonely."

"So, a person in his 50s and [-]s has been doing an unpopular and lonely job all year round."

"Also, there may be some overlap between this profession and Yuan Shengqiang."

"Then what is this occupation?"

Pang Qun listened carefully to Wang Ze's words.

After the other party asked, he couldn't think of it for a while, so he shook his head.

Wang Ze said: "Think about it, where did we go yesterday?"

Pang Qun subconsciously said: "Forestry Station..."
