Out of politeness, Liu Yi poured a glass of water and gave it to Summer. Liu Yi didn't dare to look at her more, because every time he looked at her, his heart seemed to be pierced by a sharp sword. The summer in front of me is too much like Shen Xiao.

"Are you looking into this case?" Summer sat down in a chair and looked around.

"How do you know?" Liu Yi's investigation of the case was not public. Except for the people involved in the case, the others really don't know.

"You don't have to worry about this, I want you to check it for me!"

Liu Yi snorted, "Even if you don't say it, I'll check it!" Liu Yi felt that the summer was not so simple as letting herself investigate the case, and providing clues was her purpose.

"I know, I just want to know some clues about the case, after all, I found too few clues." After Natsu finished speaking, she took out a file from her bag.

"Did you check it yourself? Why did you look into this case? Are you a loved one of the victims? Liu Yi said disdainfully.

"You don't have to worry about this! Let's take a look! Liu Yi opened the file bag and found that it was all handwritten information by Xia Xia.

The case happened one night five years ago, and now it is in a villa area in City C, where very few people can live in the villa. The villa is a family of four, and the male owner is Li Qi, 36 years old, general manager of the city's xx company. The hostess's name is Zhao Hongna, a 32-year-old executive of a listed company in the city. The two have a son and a daughter, the boy Li Jie, 10 years old, attends an aristocratic elementary school in City C. The girl, Li Hanyu, 5 years old, attends a nearby senior kindergarten.

The murderer left many traces at the scene, the murderer climbed over the fence of the villa area, and through the monitoring of the security room, he found that the man was tall, wearing a black hooded jacket, army green pants, white sneakers, and a black satchel.

The killer entered through the window on the second floor of the villa, which happened to be Li Kit's bedroom. Through the police's preliminary restoration of the scene, Li Jie shouted for help when he found the murderer, Li Qi found that his son's cry for help immediately rushed up, the murderer fought with Li Qi at the position of the stairs, and the murderer stabbed Li Qi in the chest, abdomen, arms and other places with a fruit knife he carried.

Li Qi was stabbed to the ground, and after Zhao Hongna found the murderer, she immediately ran to her daughter's room, but was caught up by the murderer, kicked her to the ground, and then used a fruit knife to stab Li Hongna four times in the back and chest.

Li Hanyu was strangled to death by the murderer on the bed in the bedroom, and the whole process took about 20 minutes, judging from the time of death, the murderer probably entered Li's house at about 1 a.m. to commit the crime. The time of reporting the case was around 4 o'clock in the afternoon of the next day, and the neighbor asked Li Qi to borrow a car repair tool, but found that there was no one, and looked through the window and found Li Qi's body lying at the staircase.

When police arrived at the scene, they found that the food from the refrigerator had been removed and consumed. The fact that the documents on Li Qi's computer had been flipped through and that the killer had logged on to the internal website of XX Company brought the attention of the police, who suspected that the murderer might be a commercial sex offender. The murderer left Li Qi's residence after eating and drinking. However, after visiting XX company, the company did not appear abnormal.

"Was the murderer a commercial espionage?" Summer asked.

Liu Yi shook his head and said: "The suspicion caused by habitual thinking can erase correct judgment. Summer was confused when she heard this, and Liu Yi asked, "What?" Don't understand? Xia nodded, and Liu Yi explained: "That is to say, the case handler will generally compare himself to a higher position, but often in this way, he will fall into the trap set by the murderer in advance." ”

"You mean the murderer was an ordinary person?" Summer asked, chin crutched.

"I can't rule out the possibility of indiscriminate killing, your information is relatively small, most of it should be published by the media, and some specific important clues are still waiting for me to come into contact with the information!" Liu Yi took a sip of water and said.

"Tomorrow, right?"

Liu Yi felt that summer should be an acute child, and said helplessly: "Yes! You didn't answer my question, what is your relationship with the Li family. ”

"It doesn't matter, I just like to investigate these cases, I just want to find the murderer for these victims!" Liu Yi can't be sure about the true purpose of summer for the time being, so let's believe her.

"Hobbies? Are you a student? Or did it work? "Liu Yijian saw the sportswear he wore in the summer, he was not very old, and he should be a student.

"It's been a few years since I graduated, but I've been looking into this case and have no job." Summer replied after a while.

"If you don't work, you have a mine at home!" Liu Yi said with a smile.

"Don't say it, I do have money in my family, what's the matter? Can't I do something? "This arrogance in the summer can be compared with Gao Xiaoqing, Liu Yi is really worried that the two of them will run into each other, just like two time bombs crashing together, doubling the damage!

Liu Yi wiped the cold sweat on his forehead and said, "It's not early, go back early!" ”

"You're defaulting! I'll look for you again! Summer dropped a phone number on the table and left Liu Yi's residence.

Liu Yi was completely stunned by this girl, and when he looked back at the last closing door in the summer, Liu Yi almost took her for Shen Xiao, and a dagger was instantly inserted into his heart, this feeling of pain couldn't be more real. At this moment, Liu Yi's phone rang, it was Gao Xiaoqing. After Liu Yi took the phone, he said with a smile: "The case is solved, I just came back!" Liu Yi told Gao Xiaoqing the general process of the case.

"Did you take your medicine on time?" Gao Xiaoqing asked.

"Yes, every day, don't worry! When will I be able to come back? Liu Yi didn't say anything, he really missed Gao Xiaoqing in his heart.

"I won't be able to go back until two months later, the school has detained me here, and my thesis has become the focus of the research meeting, really, I want to go back!" Gao Xiaoqing began to be coquettish on the other side of the phone. Liu Yi comforted her and said that if he solved the case earlier, he would go to Gao Xiaoqing.

"Really? That's great, I'll just take you around, and then we'll go back home together! Liu Yi immediately agreed, and the two chatted until Liu Yi fell asleep. But Liu Yi's night was not easy, and the past was played back in Liu Yi's mind like a movie.

In the early morning of the next day, when Liu Yi arrived at the Southern District Bureau, Xu Wei was lying on the table in the conference room and was asleep, Liu Yi put breakfast on Xu Wei's table, and said with a smile: "Viagra, the delicious food is here!" ”

I saw Xu Wei's nose sniffing, raising his head sleepily, and bringing his mouth close to the food on the desk. Liu Yi hurriedly took the food away, only to see Xu Wei move with Liu Yi's hand, and his right hand kept scratching.

"Viagra, here, here!" Liu Yi was amused by Xu Wei and laughed.

Xu Wei opened his eyes and immediately snatched the breakfast from Liu Yi's hand, "Liu Yi, I think you don't want to live anymore!" Xu Wei was just about to go up to give Liu a look, but was stopped by Wang Jianguo, "Xiaowei, hurry up and eat, there will be a meeting later!" ”

When Wang Jianguo reappeared, the six members of the old case team were all sitting in chairs. Wang Jianguo said: "The next case is strange, we still got a lot of information at the scene, even fingerprints and blood, but the murderer was not caught.

Liu Yi opened the file on the table, the 8.11C city massacre is still more famous in C city, after all, it caused a sensation in the major media at that time, and the police almost turned over the household registration of the entire C city under the pressure of public opinion, but the technology was limited at that time, which eventually led to the inability to identify the suspect.

Liu Yi did find that there was too much missing information about the summer last night, and it seems that the police did not fully release the details of the case that year. First of all, the murderer ate a total of two loaves of bread, a bottle of yogurt and two boxes of ice cream in the refrigerator at Li Qi's house. The ice cream box was left in the bedroom and on the stairs.

A total of 150,000 yuan in cash was stolen from Li Qi's family, and the strange thing is that the murderer did not take away the 60,000 yuan in the bedroom of Li Qi and his wife. Judging from the reconnaissance at the scene, the 150,000 should have been hidden in a book containing documents in the wardrobe.

In the bathroom, it was found that the medicine box had been opened, the gauze was scattered on the ground, and there were a small amount of blood stains on it. The police judged that the murderer should have been injured during a fight with Li Qi. Judging from Li Qi's several wounds, the murderer shot decisively, and all the hits were critical, indicating that he had been trained.

"Is there a DNA test for blood?" Liu Yi asked.

"At that time, the technology was not perfect, and from the subsequent detection, the murderer was a mixed-race person, and the police searched almost all the household registration information, and did not find any similar people." Liu Yi repeatedly looked at the photos on the materials.

Liu Yi found that the police at that time did verify the murderer's clothing and other clues that could be investigated, even including details such as the brand of the murderer's clothes.

"With so many clues, we couldn't catch him?" Xu Wei stuffed the last bun into his mouth.

"viagra, the fact that there are many clues kept on the scene does not mean that you can find very favorable clues. Some clues still need to be dug deeply. Liu Yi said as he carefully checked every detail on the information. Fortunately, I made up for my brain last night in the summer, and I was still prepared.

"Xiao Liu, do you have any opinions from these materials?" Wang Jianguo lit a cigarette. Liu nodded and said: "It can still be excavated, first of all, judging from the items in the refrigerator, the murderer has not touched beer and rice wine, which means that the murderer is not good at drinking." Secondly, judging from the cutting of the gauze and the photos on the monitor, the murderer's bandaging techniques are very professional and may have military experience. ”

Wang Jianguo nodded, "The police officers who investigated the case before also did a case deduction, but it was not reasonable, I always felt that it was commercial revenge!" ”

Liu Yi shook his head and said: "It's possible, or the murderer doesn't necessarily have the purpose of killing, it may be that he finds that his heart is unhappy." There is also a possibility that the murderer is a black household, or even a wanderer, who commits a random crime through this place. ”

"Then how do you explain the usage history on the computer?" Xu Wei asked.

"Viagra, do you understand what curiosity is? Think about it, if you turn on a stranger's computer, will you see if there's anything nice in it. Voyeurism is hidden deep in everyone's heart, as long as the conditions are met, it can explode! But this is also a speculation, and the specific situation can only be judged by understanding the victim's personal relationship. Liu Yi said as he checked the confessions of several people who had a relationship with Li Qi back then.

Xu Wei nodded as if he didn't understand, "I don't have a clue at all!" ”
