"Nothing?" Xu Jiuyan asked. Pen & Fun & Pavilion www.biquge.info

"And what else do you want to know?"

"What about portraits? How to draw? ”

"In Lombrosso's book The Criminals, it is clearly pointed out that the four arsonists were particularly long, with relatively small heads, and thinner than the average person."

"Who are you talking about?"

"Lombrosso, what, you've seen it?"

Xu Jiuyan shook her head and said, "No." Who is Lombrosso? ”

"Alone."

“…… Nonsense! ”

"A dead man!"

“……”

Guan Zheng smiled and introduced: "He is an Italian criminologist, psychiatrist, and the founder of the criminal anthropology school. Born into a Jewish family in Verona. He was a military doctor, director of a psychiatric hospital, and a professor at universities in Turin.

Emphasis is placed on the study of the pathological anatomy of the offender, the comparative study of the relationship between the mentally ill and the offender, the use of anthropological measurement methods as a method for studying the mentally ill offender and other offenders, and special attention is paid to the skull and physiognomy of the offender. ”

Xu Jiuyan nodded and said, "Isn't it very beneficial for our simulated portrait?" ”

"Well, there's one in the third drawer under my desk, you can take it yourself."

"You really are a god, you remember that."

"Who is like you, you don't even know where your key is."

As he was talking, Lao You came in from outside and said, "I have bought all my tickets, and I was stunned to call me back, what are you doing." ”

Guan Zheng smiled and said: "My son can see me at any time, and the murderer can't be dragged along." ”

"Okay, the world is not as big as your case."

Guan Zheng patted Lao You on the shoulder and said, "The arson case is not easy to investigate, so it takes a lot of effort." ”

"Do you still have to say that? Leave it to me. ”

When Guan Zheng and Xu Jiuyan returned to the bureau, the first thing they did was to check the surveillance. There was no suspicion at the scene, a cleaning staff was dragging the ground in the picture, and when everyone reacted, the fire had already started.

"What about the cleaners? Called for questioning. ”

"What's wrong with the cleaner?"

"She's the closest person to the camera, and if she hasn't done anything, she must have seen something."

"Just because she's close?"

"You see, after the cleaner walked over, he took a look at this corner, and then paused, and was just about to see what was going on, when the figure had just disappeared into the picture, and the fire had already started. So there should have been someone here at the time. ”

Xu Jiuyan nodded and said, "I'll find it right away." ”

After a while, the cleaner arrived. Guan Zheng glanced at the cleaner a few times and asked Xu Jiuyan, "What do you think?" ”

"Not quite like her."

"Why?"

"Instinct it!"

"Intuition is also the accumulation of a lot of experience, and you can use your intuition often in the future."

Xu Jiuyan smiled and said, "I love to hear this." ”

The corners of Guan Zheng's mouth lifted and said, "Let's go, go in and see if what you said is right." ”

Guan Zheng walked in, pulled out a chair, and said, "Hello, eldest sister, I am the captain of the criminal police brigade, and my surname is Guan." This is my colleague, her surname is Xu. I called you this time to ask about the Tang Dynasty KTV fire case. ”

The eldest sister nodded a little panickedly and said, "I know, you can ask if you have something." ”

Guan Zheng handed over a glass of water and said, "Eldest sister, don't be nervous, I'm just here to ask you about the situation." ”

The eldest sister held the cup tightly, and Guan Zheng said, "What did you see on the day of the fire?" ”

"I ...... I ......"

Guan Zheng smiled and said, "Eldest sister, what are you nervous about, I won't eat you again." Where are you from? I don't know your accent is local. ”

“…… I'm from Lin'an, and I'm married here. ”

"Really, I'm from Zhuzhou, and I'm very close to Lin'an." Guan Zheng deliberately put out a few words of Jingzhou dialect, and the thick northern accent made the eldest sister gradually relax.

Guan Zheng said again: "The children of the eldest sister's family are also in college, right?" Where to go to school and how are you studying? ”

"At NTU, I am a graduate student."

Guan Zheng smiled and said: "I'll just say that we are very fateful, I also graduated from NTU, and I am a student of bioengineering." I remember that I was soaking in the laboratory every day, and there were a lot of experimental reagents, and the smell was very bad. By the way, eldest sister, did you smell any strange chemicals on the day of the fire? ”

The eldest sister was stunned for a moment and said, "...... Yes. ”

"Is it gasoline, or is it alcohol?"

"Well, it's not, I can't tell you what it tastes like, it's a fragrance? It dissipated in a few moments. ”

Guan Zheng nodded and said, "Did you see any strange people that day?" ”

The eldest sister shook her head and said, "There are no strange people, but there is a strange thing. ”

"You say."

"The bottle at the door is not quite right, you also know that Nanyi is close to the sea, the wind is relatively strong, the bottle was filled with water to suppress the warning sign before, but the bottle that day was sprinkled somehow, I was just about to go to see it, and it caught fire."

Guan Zheng smiled and said, "Eldest sister, you won't be so evil, right?" If there is no flame to ignite, how can it catch fire? ”

"I didn't lie to you, I thought it was strange! There were no sparks, and suddenly there was a fire. ”

Guan Zheng looked at Xu Jiuyan, such an evil family?

After sending the cleaner away, Xu Jiuyan asked, "Can you really do it?" ”

Guan Zheng, like an encyclopedia, began to popularize science again: "According to what the cleaner said, it should be benzene." Any substance that exists in a liquid state at room temperature and is easy to cause combustion when exposed to fire, and its flash point is below 45 °C is called flammable substance.

Or steam is flammable and explosive, swelling by heat, easy to accumulate static electricity, high flow expansion, and oxidizing strong acids and oxidants, with different degrees of toxicity. But there is no proof that it can be lit without fire. ”

Jia Zhenkai came over with the report and said, "Master Zheng, the report is out, and the liquid is benzene." ”

Guan Zheng nodded and said, "The witness said that he caught fire without fire, what do you think?" ”

"There should be a first-class spontaneous combustion."

Xu Jiuyan asked, "Class 1 spontaneously combustible items?" ”

Jia Zhenkai said: "Class 1 spontaneous combustion products are chemically very active, and dangerous goods that are easy to spontaneously ignite in the air, such as yellow phosphorus, reduced iron, reduced nickel, and a variety of metal-organic compounds as polymerization catalysts. ”

Xu Jiuyan nodded and said, "So that's the case." ”

Guan Zheng said: "The amount this time is not particularly large, there are not many chemical plants in Nanyi City, and I can't find anything in the chemical factories for these leftovers." Immediately check the university laboratories in the city that can be exposed to the relevant substances, and be sure to find out the source. ”

Jia Zhenkai said lightly: "That, I've already checked it easily, here." ”

Guan Zheng glanced at Jia Zhenkai and said, "This time is good." ”

"Thank you, Masama."

Guan Zheng glanced at it a few times, and suddenly saw the bioengineering laboratory of Nanyi University. Xu Jiuyan pushed Guan Zheng and said, "What's the matter, what are you looking at, so stupid?" ”
