Because she had promised Xiao Su to help her investigate her sister's case back then, we went into the archives to study the case when we didn't have a case now......

Judging from the notes at the time, even if the boss caught a suspect back then, he was only a suspect. Later, the court released the person due to insufficient evidence. I said to Xiao Su while looking at the file.

Xiao Su looked at the file and said, "At that time, Guan Wei's letter to the captain mentioned that he found a clue that was missed by everyone. What is it exactly? ”

I also nodded and said to Xiao Su: "This is the key, maybe because the technical conditions were not proficient enough, so there were so many unsolved cases and mysterious cases." But if we use today's criminal investigation methods to deal with the cases of that year, I believe that they should be able to be solved. ”

I was talking to Xiao Su when Xiao Su's mobile phone suddenly rang......

After Xiao Su answered the phone, he said to me: "The call from the boss, go downstairs to gather, there is a case." ”

After I listened, I immediately went downstairs with Xiao Su and prepared to go to the scene......

The scene was in a deserted field, and after we arrived, the captain hurriedly asked Xiao Su and me to go in to ask about the situation......

"Chief, deceased female. He was about 30 years old. He was stripped of his clothes, and the cause of death was that he was strangled to death in his underwear, and his hands were tied in his underwear and hung around his neck. Before he died, he was violated, and a cigarette butt was stuffed into his lower body. There are still body fluids left in the body of the suspect, and the time of death was between eleven and twelve o'clock last night. Xiao Su reported the situation of the deceased to the captain.

After hearing this, the captain said, "Is there nothing else but the remaining body fluids?" ”

Xiao Su immediately replied: "There are hairs and fingerprints, and they have all been collected." But since the murderer dares to leave traces like this, it means that he has no previous convictions. ”

After listening to Xiao Su's words, the captain nodded. Then he asked me, "What's going on with the reporter?" ”

I replied, "Oh, there's nothing wrong with the informant. He is a police officer at the police station in this jurisdiction. At that time, they were following several thieves who had gone to the suburbs to steal cables, and suddenly found the body. ”

After the captain waited for me to finish, he thought about it and asked, "Tell me what you think." ”

I glanced at the corpse, thought for a moment and said, "Judging from the marks around the corpse, the deceased victim struggled, and the soil and the surrounding wild grass left obvious marks. This should be the scene of the first crime. ”

After I finished speaking, the captain nodded and said to everyone: "Collect the team, go back to the meeting, and analyze the case." ”

After the captain shouted to call the team up, we returned to the police station......

In the conference room of the police station, Xiao Su said: "The deceased's name is Gao Yue, and his family lives in a town not far from the place where the crime occurred. The social background is simple, and on the day of the incident, he told his parents to go to a friend's house during the day, but he was killed at night. ”

While Xiao Su spoke, I kept looking at the photos of the deceased at the scene, as well as some records of the scene.

After Xiao Su finished speaking, I asked, "Have the hair and male body fluids found on the deceased been tested?" ”

Xiao Su nodded and said to me: "Yes, I compared the database of filing personnel, and there is no match." ”

After the captain waited for Xiao Su to finish speaking, he said: "Now that the identity of the victim has been confirmed, let's discuss the specific facts of the case and specific investigation ideas." Xiaomei said first. ”

After listening to the captain's words, I shook my head and said with a wry smile: "The murderer's modus operandi this time is a bit interesting. It seems to be a bit modeled after the method of the famous Hwaseong serial murder case. ”

When I finished speaking, the captain turned to me and asked, "What's the case?" Who hosts it? I haven't heard of it. ”

I hurriedly smiled and explained to him: "It's not our country's case, the murderer in that case was also very casual when he committed the crime, strangled the victim with the victim's underwear or stockings, and then stuffed the victim's lower body with a foreign object. It's very similar to our case. ”

After listening to my words, the captain immediately slapped the table and said, "Then it's him, which country, check if it's our arrival." ”

After listening to the captain's words, I said, "There is no such possibility. There are two possibilities in my analysis, it may be the murderer's momentary creative killing, or the deliberate imitation to confuse our vision. ”

When the captain heard what I said, he fell silent......

The captain thought for a while and said, "Then what should you do next in analyzing and analyzing?" ”

After the captain finished speaking, everyone's eyes looked at me again, including Xiao Su......

I was a little embarrassed and said, "There are two possibilities, first, the murderer may have lived in the vicinity. Second, the murderer may have inadvertently passed by there and met the deceased and committed the crime, which means that the murderer had his own means of transportation. The time of death was between eleven and twelve o'clock, so let's assume that it took about an hour for the murderer to kill the victim. Then he met the deceased at about ten o'clock. ”

As soon as I finished speaking, Xiao Su immediately said loudly: "Oh, yes, there may be eyewitnesses after ten o'clock." We should look for witnesses by checking the vehicles that passed by the road on the side of the field last night. ”

After Xiao Su finished speaking, the captain immediately said: "Very good, in fact, this captain also thought of this." Xiaomei and Xiaosu's complementary analysis and conclusion are very good, so you two can get busy. The captain then sorted out the case for the remaining people. Go ahead. ”

Xiao Su and I shook our heads, then exited the conference room and headed for the traffic police team......

"It's not a way to look at it this way, so many cars, look at the license plate number little by little, and verify them one by one. We'll have to find out when this happens. "Xiao Su and I looked at the surveillance video of the road section in the traffic police team and said to me.

I smiled and said to Xiao Su: "Let's look first, there is no parking at the moment, at least it means that the murderer is not a person who is temporarily passing by the scene so far." ”

As soon as I finished speaking, a taxi was parked on the side of the road in the surveillance footage. After a man and a woman got out of the car, the taxi drove away again......

I asked my colleagues from the traffic police team to rewind the picture, and after writing down the taxi license number, I asked Xiao Su to quickly contact the taxi driver and ask him to go to the police station to assist in the investigation.

Soon, the driver went to the police station to assist us in taking notes.

Xiao Su asked the driver, "Did you notice anything unusual in the field when you passed by this section of the road last night?" Or hear shouting? ”

The driver shook his head and said, "No, I put the guest down and left." ”

I thought for a moment and asked, "Do you have an impression of those two guests?" ”

The driver thought for a while and said, "I don't have any impression, the two have been sticking together since they got in the car, and I haven't looked closely." But when the woman said to park there, she walked a little way home. ”

After listening to the driver's words, I thought about it and made a bold decision.

I took a photo of the deceased woman and asked the driver, "Is this the woman?" ”

After the driver looked at the photo, he nodded hurriedly and said, "Yes, it's her." The two got into the car in front of a hotel. It seems to be a couple. ”

After listening to the driver's words, I was a little clueless, I thought it was looking for witnesses, but it turned out to be the deceased who got out of the car, so the man who got out of the car with the deceased should be the murderer......
