When the captain saw me running out, he hurriedly asked Xiao Su to follow me, and Xiao Su followed me to the forensic department......

When I got to the forensic department, I asked a medical examiner, "Were the abrasions on the dead man lying on the rails caused by the passing of the train?" ”

The medical examiner said to me: "The wounds on the body of the deceased were indeed caused by the carriage of a mobile car, but I don't know if it was a train, a bullet train or any other car, because he was lying down the tracks." ”

After listening to the forensic doctor's words, after thinking about it, I said to Xiao Su: "You immediately go to the technical department and ask them to make chassis simulations of various vehicles of large, medium and small, and compare the injuries on the deceased's body." ”

After listening to my words, Xiao Su immediately went to the technical department......

The comparison of vehicle chassis simulation drawings is relatively complicated, so the results are not available until noon the next day......

Xiao Su finished taking the report and came back to me: "The abrasions on the deceased's body were caused by the chassis of the 18-seater Jinbei van. ”

After listening to this, I nodded and said, "The railway is the scene of the corpse, and the murderer himself has a van." ”

Just as Xiao Su and I were analyzing the case, the captain came in and said to the two of us, "There is a student from the Fourth High School who committed suicide and went to the scene. ”

After listening to this, I was puzzled and asked, "Student suicide?" ”

The captain nodded and said, "On the surface, it was a suicide, but the police officer at the police station found a note on him, and the words printed on it were: Pride." ”

Proud! It was another crime in the Seven Deadly Sins, and after Xiao Su and I listened to it, we hurriedly followed the captain to the scene......

When we arrived at the scene, the body of the hanged student had already been removed. The scene of the crime was on the top floor of the school building, and the hanged student was hung from a rain shelter on the top floor.

When we entered the scene, a medical examiner said, "The deceased was choked by a rope. The time of death was within an hour. There are no external injuries to the body, and there are rope strangulation marks on the neck. However, judging from the traces, he was first strangled to death with a rope and then hung on a rain shelter. ”

After listening to the forensic doctor's words, the captain immediately said to Xiao Su: "Go and find out who reported the case." ”

When Xiao Su went to interrogate the police at the scene, I was thinking that the three deceased were of different ages and identities. Why was the murderer characterized as a victim of the seven deadly sins? The only possibility is that the murderer knew all three of them!

At this time, Xiao Su came back and said to the captain: "Boss, I have asked, it was the deceased found by the students of these schools when they came to the rooftop to smoke, and the case was reported." ”

After Xiao Su finished speaking, he pointed to a few students beside him.

The captain listened, glanced at the students, and kicked one of the boys in the ass.

While kicking, he scolded: "Little rabbit cub, I let you not learn well, and you secretly smoke at a young age." See if I go home and don't break your leg. ”

Xiao Su and I almost didn't laugh when we saw this scene, it turned out that the captain kicked his son. And his son is also an acquaintance of me and Xiao Su, and he is the reporter of the elevator murder case "Batman".

After the captain finished educating his son, when he saw that we were all looking at him, he shouted: "Look at everything, the jade is not cut, and the little brother comes out under the stick." Okay, carry the body back and close the team. ”

After returning to the police station, Xiao Su said in the conference room: "The deceased, Bi Guoyong. I am in my third year of high school and my academic performance is very good. But he is usually arrogant, looks down on his classmates with poor academic performance, and always puts on an unbeatable face. And he often brags about how good he is, which is very consistent with the crime of pride left on the note. ”

After listening to Xiao Su's words, the captain pondered for a while and said, "How did the murderer find these three victims?" These three people don't seem to be related. ”

After listening to the captain's words, I shook my head and said, "Boss, I think it's better for us to carefully investigate the living conditions of the first two deceased." Perhaps these three have something in common. ”

After listening to me, the captain looked at me for a long time and said, "Well, I actually thought of this from the beginning. There was another murder, and I forgot about it. What, Xiaomei, Xiaosu, you two immediately go and check the living conditions of the first two deceased. ”

After listening to this, Xiao Su and I went to the units of the first two deceased to investigate......

"The first deceased, Wang Yan, was greedy and had an amazing amount of food. The second deceased, Zhang Bin, was greedy and cheap, and he was more disgusting. Xiao Su reported the investigation to the captain.

And then I found a detail......

After listening to Xiao Su's words, the captain saw that I was silent, so he asked, "You, don't pose." Let's talk about the case. ”

"Oh, the bun shop, the same bun shop where the first deceased bought the buns. I don't know who the murderer is in the bun shop, or if the diner who always goes to the bun shop. "I told the captain and Xiao Su what I thought.

After hearing this, the captain frowned and said, "Tell me about the basis and your next thoughts." ”

I sorted out my thoughts and said: "The first deceased always went to the steamed bun shop to eat, and the amount of food was amazing, and it was easy to attract the attention of the murderer in the steamed bun shop. The second deceased was greedy for small and cheap things, and it was easy to get some napkins in the bun shop, so as to facilitate chopsticks and the like. This is the same as what my colleague said when Xiao Su visited the shopping mall where he worked before his death. ”

After listening to my words, Xiao Su suddenly realized: "Yes, these deceased people are very close to the bun shop. The third deceased's school was next to the bun shop, so the third deceased must have always gone there for dinner before his death. ”

After Xiao Su finished speaking, I nodded and said, "Yes, this may be the only intersection between the three deceased in their lives." ”

"So what's next?" After listening to my words, the captain immediately asked me what I was going to do next.

After thinking about it for a long time, I looked at Xiao Su. Finally, he said to the captain: "Boss, I think it's better for us to take the initiative to lure out the murderer." Let Xiao Su go undercover in the bun shop every day and play Yohan. ”

After listening to my words, Xiao Su was stunned for a moment and said, "John? How does this look like a man's name? ”

I immediately smiled evilly and explained to Xiao Su: "Yohan Yohan, Yohan, Yohan." It's a manly man. Ah, let go, it hurts, ......" Before I finished speaking, Xiao Su immediately pinched his waist fiercely.

The captain looked at me and Xiao Su and said, "Although your proposal is very creative, if the murderer is really an extremely dangerous person, will Xiao Su be in danger?" ”

I pushed Xiao Su's hand away and said to the captain: "Let's protect it secretly, if the murderer is really carrying out the seven deadly sins, Xiao Su can use the form of debauchery to attract the attention of the murderer, so that he thinks that Xiao Su is the spokesperson of the crime of debauchery." I think he should take the bait. ”

After thinking about it, the captain didn't give Xiao Su any chance to refute, and directly agreed to my proposal, and Xiao Su went back to prepare the "Yohan" plan with an angry face......
