Shen Nuo pulled my sleeve and strode forward with me, through the alley, and we returned to the old street where Xiao and I first came. The road in Lao Cai is paved with bluestone, and the road surface is a little slippery due to dampness. There are several street lamps on the side of the street, which are said to be street lamps, but in fact, they are high bamboo poles with a yellowing bulb hanging from them.

Xiao Gang sat on the noodle stall, and he had already eaten two large bowls of noodles, which were stacked on top of each other and placed on the table in front of him. When he saw me coming, he immediately stood up. But when he saw Shen Nuo behind me, he took a few steps back in a trembling voice. Shen Nuo is now wearing a draped hair, dressed in a bright red dress like blood, and the big night does make people look a little frightened. Shen Nuo snickered, pretended to roll his eyes a few times, grimaced, and was about to arrest Xiao Gang, which made Xiao Gang even more frightened.

I shouted loudly and told Shen Nuo to stop playing. I asked Xiao Gang to hurry up and drive, and we immediately went back to the police station, Xiao Gang hesitated, and finally pointed to Shen Nuo and asked, "Are you a human or a ghost?" ”

Shen Nuo laughed out loud, "Have you ever seen such a beautiful ghost?" ”

Xiao Gang finished speaking, he glanced at Shen Nuo a few more times, paid the money and hurriedly ran to drive. Shen Nuo was still pulling my sleeve, I shook my hand a few times, Shen Nuo still didn't let go, she was looking at me with a smug face, inexplicably, I was even more angry, and pulled my hand back angrily.

Shen Nuo snorted, reached out and stroked her hair, Shen Nuo didn't know when there was an extra black rubber band in her hand, and after a few random strokes, she tied her hair up. At this time, Xiao Gang also happened to drive the car over, I sat in the co-pilot, and Shen Nuo sat in the back seat of the car.

As the car was driving, I saw the old man again, still on crutches, standing in front of his house staring at our car. It was too dark and far away for me to make out his expression, but his head was slowly turning in the direction we were moving, and finally, after a corner, I couldn't see him anymore.

Shen Nuo stretched out his hand and waved in front of me, asking me what I was looking at, and I reacted and asked about the old man. Shen Nuo sighed, saying that the old man was indeed her neighbor when she was a child, and after the fire, everyone said that Shen Nuo's family of four died. After Xiao Gang heard this, he slammed on a sudden brake, and we all turned to the back seat of the car, Xiao Gang pointed at Shen Nuo and asked tremblingly: "Then, what that old man said is true?" ”

Shen Nuo nodded: "There is indeed such a fire, what's wrong?" ”

Xiao Gang was about to cry, "You, you were also burned to death!" Xiao Gang's face turned pale, he looked at me pleadingly, I originally thought that the old man was invited by Shen Nuo to play and tease me, but now it seems that the old man was not found by Shen Nuo. I thought about it for a moment and let Shen Nuo continue.

Shen Nuo glanced at Xiao Gang and sneered: "It's still Professor Li who is bold, my brother and I have survived." That strange fire killed my parents, and when the police arrived, they saved me and my brother, but everyone didn't know about it, so everyone thought all four of us were dead. ”

After listening to Shen Nuo's explanation, Xiao Gang finally relaxed, he stepped on the accelerator again and continued to set off. On the next journey, Shen Nuo talked endlessly about the various cases she knew, and she didn't feel the slightest embarrassment because of my unreasonable relationship with Xiao Gang. And just like that, we went back to the police station.

Looking at the watch, it's been so long, it's already past eleven o'clock in the evening. I came to Zhao Da's office, and when he saw me coming back, he immediately stood up. Zhao Da told me that everyone has joined forces with the grassroots public security police and criminal police teams to go out to investigate and patrol all night, and now there are only Lao Zhang and a few other police officers in the police force, except for the people from the identification department.

And Zhao Da, who is waiting for me to come back, wants to tell me the results of everyone's meeting tonight. Zhao Da was so angry that he directly ignored Shen Nuo behind me, Shen Nuo deliberately coughed twice with some dissatisfaction, and Zhao Da finally noticed her. Shen Nuo immediately became serious again and saluted.

"Shen Nuo! Do you know how much trouble you've caused us? Zhao Da pointed to the door: "You go out for me immediately now, go to the logistics to get a police uniform to change into, otherwise, you will go back to your grassroots police force for me!" ”

"Yes!" Shen Nuo stood upright, winked at me a few times, and then jumped out again. Zhao Da sighed and said that he had been the captain of the G City Police Force for so long, and it was the first time he had met a criminal policeman who was not afraid of him. Looking at Shen Nuo's back, I felt that Zhao Da would have a headache in the future.

I asked Sun Hui where he was, and Zhao Da said that he was asleep in everyone's office, there were more people, he was not afraid, Lao Zhang and several other criminal policemen who stayed in the police team were watching him. Zhao Da pulled me aside and complained to me about the outcome of tonight's meeting. There were more than two dozen people in tonight's meeting, and they discussed for hours without coming up with anything.

Although Zhao Da was complaining, I felt that his expression was not quite right, and sure enough, he suddenly said tentatively: "However, there is an expert who said something very strange......"

I saw through Zhao Da's thoughts, he probably heard a very reasonable analysis, but the results of that analysis were different from what I said, so he didn't say anything for a long time.

"Captain Zhao, you can say it, it's okay." I smiled and asked Zhao Da to say it.

Zhao Da poured me a cup of hot water and told me about tonight in more detail. It turned out that an expert in this area at the meeting also noticed the water cup he took back from Sun Hui's house, and he said that there were only Miao Miao's fingerprints on the cup, indicating that Miao Miao poured the water.

There are also Miao Miao's lip prints on the water cup, and according to the morphological analysis of the lip prints, the lip prints are more likely to have been left by Miao Miao herself before her death. They asked Sun Hui, and Miao Miao only used her own cartoon cup, this glass, which they used to pour water for guests. So the expert analyzed that Miao Miao was pouring water for someone she was particularly close to, so she left her own lip prints on the water glass.

Speaking of this, Zhao Da suddenly stopped, he looked out of the door, and lowered his voice: "Sun Hui said, Miao Miao is pouring water for her mother......"

"Nonsense!" I interrupted Zhao Da's words, and I finally understood what Zhao Da was going to say to me, he still thought that Miao Miao's death had something to do with ghosts. Zhao Da was reprimanded by me, his face was slightly red, and I didn't give Zhao Da face: "Captain Zhao, these cases of women in red are obviously purposeful serial murder cases, and the suspect has already called me, but you are suspicious here, in this way, you will never be able to solve the case!" ”

Zhao Da was a little embarrassed, and didn't know how to answer me, so I calmed down, "Captain Zhao, that expert, there is some truth in his analysis, but there are too many loopholes." First, not all children will leave their own lip prints on the things they like, have you asked Sun Hui, does Miao Miao have this habit? ”

Zhao Da shook his head and said no.

"Second, there is not a stool in the room that can reach the feet and Miao Miao can move, the table is so high, how to put the water cup on the table, have you thought about it?" I made the second point, the so-called expert, the results of the analysis, there is no basis at all.

Zhao Da still shook his head, his face turned completely red, "Professor Li, you mean that the water was poured by the murderer?" ”

"I didn't say that, but the one who put the water cup on the table must be the murderer, so I asked the people in the identification department not to give up and continue to identify." In both cases, it was a secret room murder, and the murderer's modus operandi was so superb that I couldn't analyze how he killed people and managed to escape the scene.

Now I think there is still analytical value, and that's the cup. The person who called me can basically be identified as the murderer, and I can roughly analyze his psychology, he wants to provoke me and provoke the public security system. So he won't leave unnecessary things on the scene, that water glass, there is definitely any information hidden.

Zhao Da scratched his head in disdain and said that he would go and ask the people in the appraisal department.

I sat in Zhao Da's office and waited for a while, Shen Nuo came in, she finally changed the red clothes on her body, wiped all the lipstick on her lips, and wore a police uniform with a look, lining her face even whiter. Shen Nuo took three steps and one step at a time, jumped to my side, and sat down on his own.

"Professor Li, what do you think of my method?" Shen Nuo held his chin in his hands and looked at me with blinking.

My head hurt a little, and I didn't want to deal with Shen Nuo, who thought I didn't understand what she meant, and explained it to me again. The method she said was to use red clothes to lure the murderer into the bait. This method of luring the murderer to the bait is called "baiting" in the industry. Regarding the trapping, there is a lot of controversy in the industry, with some supporting and some opposing.

And I, on the other hand, belong to the opposition. Trapping the murderer is actually a kind of fishing law enforcement, maybe the murderer obviously does not want to commit the crime, but he is lured and commits another crime, which will also increase the sentencing of the criminal suspect when sentencing. Although the murderer is a heinous crime, he also has human rights and should be protected by the law within a reasonable range, which is my philosophy.

Moreover, the decoy is likely to pose an unforeseen danger to the person acting as the decoy, and I could not possibly agree with it. Shen Nuo was still waiting for me to answer, and before I could speak, Zhao Da ran in in a hurry.

"Professor Li! New traces have been found on the water glasses! ”

I immediately stood up and ran to the identification department with Zhao Da. There were many people around the place, and the room was newly ventilated, but there was still a very strong smell of burnt iodine. The person in charge of the appraisal department immediately handed me the information in his hand, and there was a photo on it, which was a photo of the latest appraisal results of the cup.

The cup in the photo has one more lip print than the original, and this lip print is a cracked lip......
