Now that the identity of the deceased has been confirmed, the direction of the investigation must be to investigate the social network of the deceased.

The office of the criminal investigation team was filled with smoke, and Lao Lu sat on the sofa next to me with a cigarette in his hand and said: "Ouyang, do you think that such an 18-year-old girl has just entered the society from the campus, and she is working in her own noodle restaurant, who will a girl like her have a deep hatred with?" ”

I shook the ash into the crystal glass ashtray on the wooden coffee table, and perhaps in a hurry to answer Lao Lu's question, I accidentally shook some of the ash on the outside of the ashtray.

Looking at the cigarette ash scattered on the wooden coffee table, I took a puff of cigarette and said, "A little girl like Tan Lishu, the person who has a grudge against her is most likely the person who has a relationship with her. At their age, there is a high probability that a passion kills because of relationship problems. ”

Lao Lu nodded and said, "You mean that the murderer who killed Tan Lishu may be her boyfriend?" ”

I said, "Yes, that's a big possibility. Because sperm spots were found on Tan Lishu's lower body, but judging from Tan Lishu's neat clothes, Tan Lishu is likely to have sex with a man voluntarily? So this man is likely to be Tan Lishu's boyfriend. ”

Lao Lu shook his head and said, "I don't agree with your statement, what if Tan Lishu was forced?" It's just that after having a relationship, the murderer asked Tan Lishu to put on her clothes again. ”

I said: "It is unlikely that she was coerced, because there are no injuries on other parts of Tan Lishu's body, and if it is carried out*, then there must be some bruises on her body due to violence, but in the forensic examination results, these bruises were not found." ”

Lao Lu frowned and thought for a while and said, "What if it's because the corpse is too corrupt to make this kind of bruise unrecognizable?" Or is it that the murderer threatened Tan Lishu not through violence, but through some other mental threats? For example, it is not good for her family, etc. If you think about it, young people nowadays are very protective of themselves, if it is said that they have a relationship voluntarily, why doesn't she use protective measures? ”

I didn't refute Lao Lu again, because his words were not unreasonable, although Lao Lu's consideration would make the case more complicated, but I can't deny that there is such a situation. No matter what the situation is, the primary purpose now is to find out the man who had a relationship with Tan Lishu, because this man is the key breakthrough in the case.

I nodded in agreement, and then said, "Whether Tan Lishu is willing or forced to have a relationship with this man, in short, finding this man is the key to this case." ”

Lao Lu said: "Of course. ”

I said: "I remember Tan Lishu's mother said that Tan Lishu went out on the day of her disappearance, she was elated and in a good mood. In such a hot weather, a girl who loves beauty doesn't even bring a parasol, happily and hurriedly goes out, what do you think her purpose will be? ”

Lao Lu took a puff of cigarette and said, "I guess I'm going to meet my lover." ”

I nodded and said, "Tan Lishu has been working in the store that day, and she went out purposefully in the afternoon. Then when she was in the store, she must have been in contact with the person she was dating. We can look up the relevant phone number through her mobile phone call history. ”

At the communication company, sure enough, at noon on the day of the crime, a phone number was found. The phone number had been called twice at noon that day, with the first and second time separated by half an hour. And on the same day, during the time from the morning to Tan Lishu's outing, only this one phone call came in. So I judged that this call was very likely to be the phone call that asked Tan Lishu to go out.

Based on this suspicious phone number, the police quickly found the owner of the phone number.

In the interrogation room of the criminal investigation team, I saw this man. He wears a pair of black-framed glasses, is not tall, about 1.70 meters, is less than 20 years old, and his face reveals some childishness. But this kind of childishness is more precise, a kind of naïveness, that is, the appearance of a person who seems to be intellectually unsound. I don't know why I feel this way, maybe it's just an illusion.

It's just November, and the weather is already very cool, but this man is still wearing a thin gray shirt, and his already thin body, I really can't understand how he can resist the cold.

Lao Lu looked sideways at this kid and asked, "What's your name?" ”

The young man in front of him seemed very calm, and did not seem to feel that he was being interrogated, and he said in a very confident tone: "My name is Sun Guangshan, Sun of Sun Wukong, bright light, mountain of mountains." ”

Although his self-introduction is very ordinary, I have never encountered this method of introduction in the interrogation room. Because the interrogated people are not introducing themselves or applying for jobs, they generally have a strong sense of precaution and resistance, so how can they introduce their names so clearly?

It's incredible.

Lao Lu continued to ask, "How old are you?" ”

Sun Guangshan actually cocked Erlang's legs, leaned on the chair leisurely, and said: "Born in August, I just turned 20 years old this year. ”

His actions didn't look like he was being interrogated, but like he was running a talk show.

I thought in my heart, this guy's psychological quality is too good. However, his performance is extremely inconsistent with his age.

Lao Lu frowned and asked, "Do you know the purpose of inviting you to the police station today?" ”

Sun Guangshan actually sneered and said, "Of course you know, you want to investigate the cause of Tan Lishu's death." You don't have to investigate, Tan Lishu was killed by me. ”

Lao Lu and I glanced at each other, and I thought to myself, this guy admitted that he killed someone so quickly? This case was solved a little too quickly, right? No, there must be something strange about this, a real criminal must be on guard, and he is trying to get rid of the crime. In addition, this is a vicious homicide case, and the idea of paying for life has been deeply ingrained in people's hearts since ancient times. This is a great crime, how could he admit it so easily?

So I walked to the iron fence, looked into Sun Guangshan's eyes and said, "You said that you killed Tan Lishu, then tell me, how did you kill her?" ”

Sun Guangshan coughed twice, cleared his throat, and said calmly: "I am Tan Lishu's boyfriend, and I asked her out that afternoon, mainly to talk about one thing. I asked Tan Lishu not to continue working in her family's noodle restaurant, because she wouldn't make much money at all. She's already my woman anyway, and I'm tired of playing with it, so I ask her to go out and sell it, and she will definitely make a lot of money with her appearance and figure at her age. But this woman she didn't know dared to refuse me. So I called some of my brothers to rape her and beat her, but I didn't expect to shoot her too hard and beat her to death. In the end, we threw her body in a dry well. That's the way it is, Tan Lishu was killed by me, arrest me. ”

After listening to Sun Guangshan's explanation, Lao Lu stood up suddenly, slapped the table hard, and roared angrily: "Mom, you bastard, Lao Tzu has to make this evil breath for the deceased today." ”

After Lao Lu finished speaking, he rushed towards Sun Guangshan. It seems that Lao Lu was angered by Sun Guangshan's confession, and he wanted to enforce the law violently or something.

I stopped Lao Lu and said loudly: "Comrade Lao Lu, can you be sober?" This guy is complete nonsense, I don't think this guy is a murderer at all, but a mental patient. ”

After Sun Guangshan heard my words, he also stood up and shouted loudly: "Who is mentally ill, you are fucking mentally ill." Tan Lishu was killed by me, I killed ......"

The manic Sun Guangshan was quickly pressed on the table by the two criminal policemen beside him.

I glanced at Sun Guangshan, who was still struggling in vain, and then said to Lao Lu: "Don't worry, I can prove that he is lying by asking a few questions." ”

Lao Lu gasped and said, "Okay, you ask." With that, he sat down in a chair next to him and lit a cigarette.

I asked the criminal police to let Sun Guangshan go, and said to Sun Guangshan: "When we found Tan Lishu, her legs were tied, since you beat everyone to death, why do you still tie her legs?" ”

Sun Guangshan shook his left leg and said in a rogue-like tone: "Yes, it was her leg tied so that she wouldn't kick and kick indiscriminately." ”

I glanced back at Lao Lu, who looked at me, didn't speak, and took a few puffs of cigarette vigorously. Because we all know that Tan Lishu is tied with her hands instead of her legs.

I said, "Since you have done it to Tan Lishu*, why do you still wear her skirt?" ”

Sun Guangshan was still shaking his legs, tilting his head and saying, "Who said that you must remove your skirt?" Isn't it okay to set it off. ”

I could feel Lao Lu behind me, throwing the cigarette butt to the ground with a large movement, and I heard the sound of stepping on the cigarette butt with the sole of his foot.

Of course, we also know that the deceased Tan Lishu was wearing jeans, not a skirt.

I continued to ask, "Aren't you afraid of being found by throwing your body in a dry well near the town of Lonza like this?" ”

Sun Guangshan said: "The broken well has been abandoned for so many years, and the devil knows how you found it?" ”

Lao Lu finally couldn't help it anymore and yelled at Sun Guangshan: "Boy." Don't mess around, Tan Lishu didn't kill you at all, Tan Lishu's body was not found in Longsha Town at all, you are talking nonsense at all. Say, why do you want to be a scapegoat for the murderer? Why bear the responsibility for homicide? What is your relationship with the murderer? ”

Sun Guangshan did not show weakness, stood up and broke his heart, and roared with spittle: "Tan Lishu was killed by me, I killed ......"

Of course, he was once again faced down sideways and pressed down on the table.

Later, the police investigated Sun Guangshan and learned from his family and neighbors. Sun Guangshan has had paranoia since he was a child, although he usually can't see any difference from ordinary people, but after deep contact with him, you will find that he often talks about things that are not true. also learned that Sun Guangshan had known Tan Lishu since he was a child, and pursued Tan Lishu, but was rejected by Tan Lishu. But Sun Guangshan's friends all know that he is very infatuated with Tan Lishu, and after learning that Tan Lishu died, he once cried and made a fuss and smashed a lot of things at home. After that, his mental state became even more bizarre.

We sent Sun Guangshan to a psychiatric hospital, and after examination, it was learned that Sun Guangshan was suffering from delusional disorder. It seems that everything he said to us in the police force before was because he had told him what he had come up with after Tan Lishu was killed.

This clue that was finally discovered was actually made up by a psychopath, which inevitably made us a little disappointed.

So when Tan Lishu left the noodle shop on the same day, no one else asked her out? Or was it agreed a few days ago?

I have a more reliable idea, that is, Tan Lishu's contact with the murderer is not through phone calls and text messages, but through QQ. Because at their age, the frequency of use of QQ is very high (at that time, WeChat was not yet popular).

We visited Tan Lishu's home again, and with the permission of her mother, Feng Guifen, we turned on Tan Lishu's desktop computer.

Fortunately, Tan Lishu's QQ in the computer is saved with a password and automatically logged in.

After logging in to QQ, I found that 80% of Tan Lishu's QQ friends are young male friends. Of course, at her age of yearning for love, it is understandable to find a man who can be entrusted with life and enjoy the happiness of love among many male friends.

After QQ opened, whether it was in the QQ space or in the QQ dialog box, there were a lot of messages, most of which were words in memory of Tan Lishu, and I couldn't help but feel sad when I saw it. And Feng Guifen next to her, after seeing these messages, she couldn't cry anymore.

However, among the many QQ friends, I found that one QQ friend was very abnormal.

This QQ friend is divided into a separate group.,The name of the group is 'dear',QQ is called 'my man',Of course, this QQ name is just a note.,His real screen name is 'Gentle Wolf'。

In Tan Lishu's QQ space, you can see a lot of messages about 'gentle wolves', messages about Tan Lishu's words, messages about each other's 'good morning and good night', and messages of laughter and flirtation. Obviously, this 'gentle wolf' should be Tan Lishu's boyfriend.

But the strange thing is that on August 25, the day Tan Lishu disappeared, this 'gentle wolf' never left a word.

In the chat logs, we found out a lot of chat content between Tan Lishu and 'Gentle Wild Wolf'. The content is all sweet and even explicit love words, and there is never a dispute at all.

In the chat log on August 25, the content of the chat was not available until after 2:29 p.m. And the last words of the two were 'I'm waiting for you at the door' and 'I'm out'.

I can be sure that Tan Lishu was asked out by this 'gentle wolf' on the day of her disappearance.
