"The lives of these children are so good now, and they smoke so well, it's too luxurious." The captain came into the office in the morning, threw me a pack of cigarettes, and said to me.

Xiao Su said on the side: "The living conditions are better now than before. The children began to compare what they could eat, drink, wear, and use, but looking at the pack of cigarettes you threw over, it is estimated that his parents are not in tune, and they don't care about the children, they only know how to give money. ”

"I took that pack of cigarettes out of my son's school bag." The captain said lightly to Xiao Su. With that, the captain went into his small office......

As soon as the captain left, I said to Xiao Su: "Just look at the usual virtue of the head, he searched all day, and his son is quite good at enjoying it." ”

As I spoke, Xiao Su hurriedly winked at me, and when I looked at it, I guessed that the captain was already standing behind me.

As soon as I turned my head to explain, the captain said to me and Xiao Su with a dark face, "Okay, Xiaomei, bring me back the cigarettes." All went to the scene, there was a case. ”

After the captain finished speaking, he picked up the box of cigarettes again. Xiao Su and I hurriedly followed the captain to the scene......

At the scene, in an ordinary bungalow in a shanty town, a boy was killed! After we arrived, the captain hurriedly let Xiao Su and I enter the scene to negotiate the situation......

"Boss, the deceased was stabbed in the back. Dead on the ground, the knife plunged into his body from the back. And it was not pulled out, and he died of excessive blood loss. The time of death was between eight and ten o'clock last night. Xiao Su told the captain about the deceased.

After listening to Xiao Su's words, the captain asked me again, "Did the informant ask from there?" ”

I hurriedly replied: "The complainant is the grandfather of the deceased, and the parents of the deceased worked outside the home all year round. Every day, I went to my grandfather's house to live by myself after dinner, and there were no traces of damage to the doors and windows at the scene. ”

By this time, the deceased's grandfather was already crying unconscious.

When the captain was about to call for the team, a colleague who stepped on the card hurriedly called me over, and when he was moving the body of the deceased, he found a line of blood written on the deceased's hand: My father killed me.

I glanced over and looked at the deceased's finger, there was a wound on the finger, this line should have been written by the deceased before he died, but it seemed that something was wrong......

I hurriedly told the captain about the situation. After listening to this, the captain said: "Get the body back to the bureau first, and immediately arrest the deceased and his father." Collect the team, go back to the meeting, and analyze the case. ”

After the captain finished speaking, he took us back to the police station......

In the conference room, Xiao Su said: "The deceased's name is Zhu Long, he is sixteen years old this year, and he is still in school. According to the confession of the deceased's grandfather, no property was lost in the house, and there were no traces of damage to the doors and windows. ”

After Xiao Su finished speaking, the captain asked: "Did the deceased's father catch it, didn't the deceased write that his father killed him?" ”

After the captain asked, Xiao Su opened the notepad and said, "The father of the deceased is named Zhu Sichuan. He has been working abroad all year round, but he returned to the city with his wife a week ago. On the train at 11 o'clock last night, the two returned to the city where they worked, and we have notified the railway police to arrest the two and are on their way back. ”

From the beginning of today's case analysis session, I didn't say a word because I always felt that something was wrong......

When the captain saw that I had not spoken, he asked me, "You, stop playing silence." If you haven't been talking, have you found something again? Say it and analyze it together. ”

After listening to the captain's words, I hurriedly shook my head and said, "I didn't find anything, there is a place I don't understand, I haven't figured it out, I'm thinking about it." Haven't the parents of the deceased been escorted back now, and let's talk about it when the person in question returns? ”

After listening to my words, the captain called the meeting to an end, and we waited for the railway police to escort the suspect back......

"Boss, we interrogated the suspect, the night of the crime. The two of them were on the train at nine o'clock in the evening, and they had already left home at seven o'clock. And we also retrieved the surveillance footage of the train station. The two had indeed arrived at the train station at 8:15 p.m. last night. Therefore, the father of the deceased did not have the time to commit the crime. After Xiao Su interrogated the suspect overnight, he immediately reported the situation to the captain the next day.

When the captain had heard this, he lit a cigarette and said, "Then what does that line mean?" Why did his father kill him? ”

At this point, I interjected, "The murderer deliberately wrote it to interfere with our view." ”

After I finished speaking, the captain and Xiao Su looked at me puzzled.

I smiled and explained to them, "I thought about it yesterday and finally found out that something was wrong. Guess what's wrong? ”

The captain glared at me and said, "If you have a fart, hurry up, when is it, hurry up." ”

I also lit a cigarette and said, "When I looked at that line yesterday, I noticed that the font was neat, and it didn't look like it was written in a hurry before I died." I also observed the wound on the deceased's hand, and there was a wound on the index finger that was clearly cut by a knife. ”

Xiao Su hurriedly nodded at me and said, "You mean that the murderer cut the deceased's finger with a knife, and then he held the deceased's finger and wrote on the ground?" ”

At this time, the captain also asked suspiciously: "Didn't the scene say that there were no other people's fingerprints and footprints?" There are only fingerprints and footprints of the deceased's family of three and the deceased's grandfather. ”

After the captain finished speaking, he hurriedly said to me and Xiao Su: "I know, his grandfather, the murderer is the deceased and his grandfather." Hurry up, you two hurry up and get him back. ”

"Can't you? Kill yourself and then report it yourself? Illogical, right? After Xiao Su listened, he immediately asked the captain.

The corners of the captain's mouth raised, and he said to Xiao Su: "Childish, have you ever heard a thief shouting to catch a thief?" The old man must have deliberately reported the crime because he wanted to clear his suspicions. You two hurry up and get him back for me. ”

I shook my head and said to the captain, "No, the old man also said, usually my grandson goes to his place to eat, and he goes home to live in the evening." On the day of the report, he went to knock on the door when he saw that his grandson had not gone to breakfast. I think we can secretly investigate the deceased grandfather, don't be too public, in case it's not, it's too bad. After all, the grandson is gone. ”

After listening to this, the captain agreed with my idea and asked Xiao Su and I to secretly investigate the deceased's grandfather......

When we arrived at the deceased's grandfather's house, the old man hurriedly came and knelt down and said to me and Xiao Su: "Comrade policeman, I beg you, please catch the murderer and avenge my grandson." ”

Xiao Su and I hurriedly helped the old man up, and asked what the old man was doing that night. After asking for a while, the parents of the deceased saw that the old man was so sad that they begged us not to mention the matter for now, so as not to make the old man too sad. Seeing this, Xiao Su and I also briefly understood the whereabouts of the old man that night, so we hurriedly got up and said goodbye. After leaving the deceased's grandfather's house, Xiao Su and I hurried back to the police station to report the situation to the captain......

"Boss, we have checked, the deceased's grandfather played mahjong at home with several neighbors until ten o'clock on the night of the crime, and he did not have the time to commit the crime." I reported the investigation of the deceased's grandfather to the captain.

When the captain heard what I said, he fell silent, as if he was thinking about something......
