"Hurry up. Cut him. Quick, your soldiers are digging roots! "Xiao Su and I were idle, so we used the computer arcade machine to beat a few Street Fighters. But the captain made a strong move behind Xiao Su......

Xiao Su slammed the keyboard and said, "Don't play anymore, this ink is still digging roots, digging roots." Does the boss know what it means to dig roots? ”

The captain smoked a cigarette and said to Xiao Su: "I know, dig the roots, the Northeast vernacular." It is the name given by the common people themselves, which means that they use agricultural hoes, pickaxes, etc. to hit others on the head, causing injuries or deaths. Isn't there a trick you use for the GI called digging roots? ”

"No more playing." Xiao Su was angry, pushed away the keyboard, and returned to his desk.

The captain came over to me and said, "Come, Xiaomei, brother educates you." ”

I laughed and said, "Do you know how to play?" ”

The captain snuffed out his cigarette butt, sat down next to me and said, "Do you know how to play?" You weren't born when I played Street Fighter in the arcade. I had a nickname back then, Street Fighter Prodigal, come on, hurry. ”

After listening to it, I reluctantly adjusted the game again. But at this moment, the phone in the captain's office rang, and the captain hurriedly went in to answer the phone......

After the captain answered the phone, he came out to me and Xiao Su and said, "Hurry up and call people out of the scene, there is a case." ”

After the captain finished speaking, Xiao Su and I hurriedly gathered the personnel and followed the captain to the scene......

At the scene, in an alley at the back gate of the city's state-owned iron and steel plant, a man died in the alley......

After we arrived at the scene, the captain hurriedly asked Xiao Su and me to inquire about the scene......

"The head, the deceased male, named Yi Xiupeng, was an employee of the No. 1 Steel Factory. He was hit in the back of the head with a hard object, and it was fatal. The time of death was between twelve midnight and two in the morning. He didn't have any possessions on him. After Xiao Su asked about the situation, he immediately reported it to the captain.

The captain nodded and said to me, "What's going on with the informant?" ”

I hurriedly said to the captain: "The informant is also an employee of the No. 1 Steel Factory, and he passed by this place when he got off the night shift in the morning, and hurriedly reported the case after finding the deceased. The colleague who stepped on the evidence said that the murderer did not leave any traces when he committed the murder. ”

After listening to my words, the captain nodded and said, "Collect the team, go back to the meeting, and analyze the case." ”

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

In the conference room of the police station, Xiao Su said to the captain: "After investigating the social background of the deceased, I found that he usually lives a simple life, that is, he goes to and from work, is unmarried, and is an old bachelor. and he has never had a grudge against anyone. The time of the crime should have happened to be the time of the second shift. ”

After listening to this, the captain nodded and said, "On the surface, there should be no possibility of vendetta, but what is the murderer's motive?" Love killing? Will he have some lover or something? Xiaomei, Xiaosu, and the two of you carefully investigate his social background, social relationships, etc. Go ahead. ”

After the captain finished speaking, Xiao Su and I immediately withdrew from the conference room and went to investigate the deceased carefully......

"After two days of investigation, there is nothing suspicious. And he lives with his parents, and his personal emotions are blank, ruling out the possibility of love killing. There is no vendetta either, the nature of the deceased's work is three shifts, and he goes home after work. Early in the morning of the third day, as soon as the captain came to the office, Xiao Su told the captain about the investigation in the past few days.

After listening to this, the captain nodded and went back to the office, without saying anything specific......

After a while, the captain frowned again and said, "Out of the scene, there is another murder." ”

The scene was in a remote alley, and the deceased was a woman. When we arrived, Xiao Su and I immediately went to inquire about the situation......

After Xiao Su asked about the situation, he hurriedly said to the captain: "Boss, the deceased is a woman, aged between twenty and twenty-five. The time of death was between two and four o'clock in the morning today. He was hit in the back of the head and died in one fell swoop. According to the medical examiner, this wound is consistent with the head wound of the male deceased found in the alley behind the No. 1 Steel Factory, which can prove to be the same murder weapon. The deceased was not violated, had no belongings on him, and did not have a wallet or identification documents. ”

When the captain had finished listening, he looked at me.

I thought about it for a while, and said to the captain: "The money is gone, could it be just killing people for money." It should be a roadblock robbery, and this is the same as the last crime scene, which is a remote, unlit, and sparsely pedestrian section. ”

After listening to my words, the captain was silent for a while, not knowing what he was considering......

After a while, the captain said, "Go back to the police station." ”

The captain did not say his cross mantra this time, but only said a few words lightly, and led us back to the police station......

After returning to the police station, this time the captain did not organize a meeting, but took Xiao Su and me to the forensic department......

After arriving at the forensic department, the captain asked the forensic doctor, "Are you sure it's the same murder weapon?" ”

The forensic doctor nodded and said, "Yes, this murder weapon is very strange, it should be specially made." The striking surface has a square blunt object, and there is a raised hard object in the middle of the square. In this way, a kind of inertial impact force is formed during the blow, and the blunt object can directly shatter the back of the victim's skull, and the protrusion plays the role of killing the victim. ”

After listening to this, the captain said with a smile: "Authentic planing." ”

After the captain finished speaking, he took the forensic doctor to the technical department to make a simulated restoration of the murder weapon. But on the other hand, let Xiao Su and I find out all the files of some similar robbery cases in the city from 10 to 15 years ago, and prepare to investigate them to see if there are any cases similar to the murder weapons in these two cases......

When Xiao Su and I were checking the case file, the captain took the simulated restoration of the murder weapon and said to the two of us: "Check it according to this." Investigate some cases where the victim was killed. ”

I took the simulation, looked at it carefully, and said, "Is this thing reliable?" ”

The captain nodded and said: "According to the forensic analysis of the deceased's focus after being beaten, the technical department has combined the force of the human arm and the length of the murder weapon when holding the murder weapon, how long the murder weapon can cause the brain scar after the deceased, so as to make such a thing, which is basically in line with it." ”

After listening to the captain's words, I nodded and said, "The length of the murder weapon shown in the picture is 70 centimeters, so it is very likely that the murder weapons are not all made of iron or metal, otherwise the murderer is carrying a long iron bar all over the street looking for a target to follow?" ”

"It's made of wood, only the striking surface is made of metal." Xiao Su interjected on the side.

I listened to Xiao Su's words, nodded, and said, "There is a great possibility, and the forensic doctor said that this kind of murder weapon is very strange, and ordinary people should not be able to do it." The murderer should have been a murder weapon made by himself. ”

After I finished speaking, I ignored the captain and Xiao Su, and continued to check the cases of the past cases in our city......
