After learning about the relevant situation from the deceased Jiang Qingxi's roommate Qi Lingqiu, everyone was about to leave when they were suddenly stopped by her.

Then, she told the police about a strange incident.

"You mean, you often lose things, socks?"

Lu Ke was stunned for a moment, suspecting that there was something wrong with his ears, or maybe there was a problem with his understanding.

Qi Lingqiu nodded very firmly: "Yes, if you lose your socks, there should be a thief." ”

As a criminal policeman, after hearing this sentence, everyone's first reaction was to encounter a theft case, and subconsciously asked: "What else did you lose besides socks?" ”

Qi Lingqiu still replied very firmly: "I only lost my socks, and I didn't lose anything else." ”

At this moment, Lu Ke was even more puzzled, and said very puzzled: "You mean, there is a thief in the school who specializes in stealing socks?" ”

As a criminal policeman, we have also participated in the detection of many theft cases since we joined the police, but this is the first time I have heard of a thief who specializes in stealing socks.

Su Simeng rubbed his ears and said with some doubts: "How can there be a thief who specializes in stealing socks, is it that when you were drying your socks on the balcony, the wind blew away?" Or maybe you accidentally threw away your socks while throwing out the garbage. ”

Hearing the questioning, Qi Lingqiu subconsciously raised his voice and accentuated his tone: "It's true!" Really lost! A lot of people have lost their socks! ”

Lu Ke frowned, faintly feeling that this matter was a little strange, and continued to ask her: "Who has lost their socks?"

Qi Lingqiu replied: "The people in our dormitory building have basically lost their socks, so we don't dare to dry our socks openly now." ”

Lu Ke asked again: "Is it only your dormitory building that has been lost?" ”

Qi Lingqiu thought for a while and replied seriously: "Not only our dormitory building, but basically all the girls' dormitories have lost their socks. ”

Lu Ke paused and continued to ask, "Is there only a girls' dormitory?" Have you ever lost your socks in the boys' dormitory? ”

Qi Lingqiu shook his head: "I haven't heard of this. ”

Lu Ke tilted his head slightly and looked at her: "Then have you lost your socks?" ”

Qi Lingqiu nodded: "I also lost it." ”

Lu Ke continued to look at her: "What kind of socks did you lose?" ”

Qi Lingqiu didn't know how to answer, so he just said, "It's just ordinary socks." ”

Lu Ke asked, "Are they new socks or washed socks?" ”

Qi Lingqiu blinked and said in a deep voice, "Both." ”

As his understanding of the situation deepened, Su Simeng also began to feel that something was not quite right in this matter.

He picked up and asked, "When did you lose your socks?" ”

Qi Lingqiu thought for a while and said seriously: "I often lose it, and I lose it every few months." And we lost it when we went out to class during the day, and when we came back from class, we found that the socks hanging outside were gone, and the wardrobe was also turned over, so we all locked the cabinet later. ”

Hearing this, everyone finally understood the whole story of this matter.

Lu Ke twisted his fingers and carefully analyzed the theft: "Clear target, a cooling-off period of several months, understand the class time of the students, if it is not a theft within the students, then there is a thief in the school who can freely enter and exit the girls' dormitory and is obsessed with women's socks." ”

Mo Yufei raised her head and looked at Lu Ke: "Fetish, or foot fetish." The thief who is obsessed with women's socks is likely to be a man, but how can there be a man who can freely enter and exit the girls' dormitory? ”

Su Simeng scratched his head, and asked Qi Lingqiu again: "Do you report to the school about often losing socks?" ”

Qi Lingqiu spread his hands to him helplessly: "We reported this matter to the dormitory manager, but the dormitory manager said that he had no choice, after all, such a thing as losing socks, even if the police were useless." ”

Mo Yufei asked her again: "Isn't there a surveillance at the door of the dormitory building?" Just look it up and find out who the thief is? ”

Qi Lingqiu smiled bitterly and said lightly: "The dormitory manager said that password authority is required to access monitoring, and it is necessary to apply to the security department, and the procedure is very complicated and troublesome. ”

Su Simeng smiled faintly, breathed a long sigh of relief, and felt that he now had two big heads: "Alas, it's okay now, there is not only a murderer in the school, but now there is another fetish thief." ”

Mo Yufei thought for a while, and suddenly asked, "Will there be any connection between these two things?" ”

Lu Ke took a deep breath and said lightly: "Maybe there is, maybe there is no ......"

This incident can be regarded as an episode, just like the story of Baobenlu, except for Qi Lingqiu's description, there are no more clues.

It is very difficult to catch this thief who steals socks.

Leaving the dormitory building, the angry Obasang really lay down in the guard room and slept, and when everyone left, she didn't wake up.

"Now it seems that Jiang Qingxi is very likely to go out last night to make extra money, and the murderer is the person who is with her 419."

On campus, Lu Ke analyzed as he walked.

Mo Yufei continued: "But judging from the autopsy, there is only obscenity and no sex. Behavior, again in the woods of the school, is somewhat inconsistent with 419's situation. ”

Su Simeng thought for a while, took a step forward, took the words, and said: "Fetishism, which belongs to a kind of sexual preference disorder, refers to abnormal sexual behavior, and belongs to a sexual deviation under psychological reaction. This patient will pass some non-living objects as sex. Arousal as well as sexuality. Satisfying the stimulus, even without passing sex. behavior, but also sexually satisfying. Demand. ”

Mo Yufei also stepped up, and then said: "In other words, the murderer of Jiang Qingxi is likely to be a serious fetish patient, who has fulfilled his sexual needs through some way other than sex?" ”

Su Simeng and Mo Yufei glanced at each other and immediately said, "Maybe the 419 object that Jiang Qingxi chose last night was a patient with a serious fetish psychology, which just explains why sex didn't happen. violated, and Dures in Jiang Qingxi's pocket was not used. ”

Lu Ke suddenly stopped and thought for a while: "But why do you kill people?" ”

This question, and the most critical one, has not yet been answered.

As long as the answer to this question is found, the case will be solved.

Lu Ke froze, took a step, walked in front, and said lightly: "There are still many possibilities in this case, the murderer may be a fetish patient, or he may not have sex. It is also very likely that a person with ability has become a crime of passion because of something unexpected that prevented him from carrying out his plan to carry out the next sexual act. ”

Su Simeng and Mo Yufei looked at each other, sighed one after another, and followed Lu Ke towards the school gate.

At the school gate, a young man in a security uniform was staring at them with the eyes of a prisoner.

As soon as the three of them approached, the security guard suddenly spoke: "What are you doing?" Is this car yours? Move away! ”

After speaking, he pointed to a plainclothes police car parked at the school gate.

Lu Ke settled down, walked directly to the security guard, and asked as he walked, "Are you a security guard at the school?" ”

The security guard snorted coldly and asked, "What are you guys doing?" Who let you in? Registered? ”

Lu Ke smiled faintly, came to the security guard, took out the police ID from his pocket and showed it to him: "From the Criminal Investigation Detachment of the Municipal Bureau." ”

The security guard met the police, and the two were half of the same.

The security guard stared at the police ID for a while, his expression was still serious, but his tone softened significantly: "The police also have to register with the doorman......
