"Wake up, cheer up, let's talk about psychological warfare during criminal investigation." The captain spoke to us from the conference room.

The captain was alone in the conference room, and we were drowsy.

I'm just now realizing that I'd rather go out every day to handle a case than listen to the captain talking here every day when there is no case......

"Wake me up this time, there's a case." The captain answered the phone and yelled at us.

When everyone heard about the case, they immediately cheered up and rushed to the scene......

The scene was by a river on the outskirts of the city, and the body was washed up from the river to the shore.

When the captain arrived at the scene, he was stunned when he saw the corpse. I don't know how he was abnormal this time, but before Xiao Su and I could ask about the situation, he said, "Collect the team and go back to the body for an autopsy." ”

Everyone was stunned when they heard this, why did they have to go back just after arriving at the scene? However, the captain had already spoken, and everyone began to evacuate one after another, and on the way back to the police station, the captain did not say a word......

After returning to the police station, the captain looked at the crowd, and finally said to me and Xiao Su, "You two, go and wait for the autopsy report." Wait for the report to come out before the meeting. When the captain had finished his order, he returned to his office alone.

Xiao Su and I went to the forensic department......

"Boss, the results are out, do you have a meeting?" After getting the autopsy report from the medical examiner, I went back to my office and spoke to the captain.

The captain nodded and walked towards the conference room.

In the conference room, Xiao Su said: "The deceased, female, identity unknown. He was between the ages of twenty-five and thirty. He had been subjected to very violent abuse before his death and had not been violated. The time of death was more than forty-eight hours. ”

After listening to Xiao Su's statement, the captain lit a cigarette and said, "Also, the clothes worn by the deceased." ”

Xiao Su was stunned for a moment after hearing this, and then continued: "The style of the deceased's clothes is a pink shirt that was popular in the late eighties and early nineties. But it should have been changed into, not her own clothes. ”

The captain bowed his head and pondered for a while and said, "Twenty-five years ago, the same case happened in our city. It has not been solved so far and has become an unsolved case. The modus operandi, the place where the body was dumped, and the style of clothing on the deceased were all the same. However, due to the limited criminal investigation technology at that time, it was impossible to solve the case at all. ”

After the captain finished speaking, he looked at me again and said, "You also know the person in charge of the case at that time, it was your grandfather, and this case was the last case he dealt with before he retired." Whether you can solve the case this time is up to you. ”

After listening to the captain's words, Xiao Su interjected and asked, "Boss, didn't Xiaomei's grandfather pick the lock?" Didn't you have to arrest and assist in the investigation before? ”

The captain explained to her with a smile: "Actually, I know both of your information. Xiaomei's grandfather is our old director, and he has nothing to do after retirement. The lock was unlocked. Over the years, there have been three unbroken pieces in our city. Among them, the old director has two in his hands, and I have one in my hand. Xiaomei, your grandfather must have a record of this case, you should go home and look for it. ”

After listening to the captain's words, I immediately got up and went home, and I remember that my grandfather had a notepad of the cases he used to handle......

"No fingerprints were taken from the corpse, and it was deliberately thrown into the river because the river water can wash away the traces of the murderer's crime." After I went home and found my grandfather's log, I synthesized the contents of the log left by my grandfather, rearranged the ideas of the case, and said to the captain.

The captain looked at me and said, "It took you more than five hours to go back home?" It's going to be off work in a while, and I have to go home and cook. Gather everyone for a meeting, and you try to speak as quickly as possible. ”

The captain reconvened a meeting of all the officers.

In the conference room, I said, "The fact that the murderer was able to run so far to dump the body shows that he must have his own means of transportation." ”

At this time, the captain also said: "The autopsy report said that the deceased was subjected to very cruel torture before his death. That shows that the murderer is a person with very violent tendencies. ”

After Xiao Su listened, he interjected and said, "Boss, I have an objection. ”

After hearing this, the captain glared at Xiao Su and said, "You're in a hurry to get off work, you hurry up, Quickly!" ”

Xiao Su playfully stuck out his tongue and said, "Could it be that someone imitated the crime?" Like you said, it's been 25 years since the unsolved case of that year. The murderer has not committed another crime in 25 years, so why did he suddenly commit another crime? Assuming that the murderer was 40 years old when he committed the crime, then 25 years have passed, and he should be 65 years old now, can he still kill people? ”

After listening to Xiao Su's words, the captain was also speechless for a while.

When I saw this, I was about to speak, when the captain suddenly said, "Okay, get off work." When it's time to discuss, if you two like to discuss, stay alone and discuss, don't take up everyone's time. Anyway, it's been hanging for 25 years, and it's not a day off. Meeting. ”

After the captain finished speaking, he quickly turned around and left the conference room......

After the others also got off work one after another, I said to Xiao Su: "You go first, I'll go to the archives and check the specific information of the case that year." My grandfather's diary book is full of suspicious analyses and simple on-site records. ”

Xiao Su nodded and said to me, "Then you go, I'll buy you dinner." ”

After Xiao Su finished speaking, he left the police station, and I walked towards the archives, hoping to find clues from the files of that year......

After comparing the dossiers of that year, I came to a new conclusion.

The next day, as soon as the captain entered the office, I said to him, "Boss, I don't think this case is as simple as violent murder, but throwing the body." I have combined the indications of the two cases, and I suspect that the cause of this case is a case of female abuse. ”

After I finished speaking, Xiao Su on the side suddenly asked: "But the deceased was not violated, and the 25-year-old deceased was not violated." ”

After the captain waited for Xiao Su to finish speaking, he nodded and said, "Yes, how do you explain this?" ”

I said to the captain and Xiao Su: "The reason why the deceased did not suffer from the assault is because the murderer may have an obstacle in 'that aspect'!" So he had no choice but to use violent ways to vent his desires. ”

After thinking about it, I continued: "The style of the shirt on the deceased's body is exactly the same as that of the twenty-five years, and it is no longer available on the market, so it should be the murderer's private collection. ”

"Does he have mental illness? Is there a desire for such a style of clothing? After listening to my words, Xiao Su asked me.

I nodded at her. The captain said at this time: "Xiaomei, you stay at the police station and comprehensively analyze the case and the murderer's motives. Xiao Su, you immediately go to verify the identity of the deceased and see if you can find any valuable clues. ”

After the captain explained to the two of us, he went back to the office alone.

After Xiao Su left, I began to think in my heart: why did the murderer commit the crime again after an interval of twenty-five years......
