Xiao Su and I led our colleagues who stepped on the certificate to the building where the accident occurred again to collect clues on a large scale......

Soon, a colleague found a clue at the elevator door on the 12th floor, and Xiao Su and I immediately went to the 12th floor......

After arriving on the 12th floor, a colleague who stepped on the certificate called us to the elevator and pointed to the lower end of the elevator door and said, "That's it, you can conclude that the person fell from here, this floor is the 12th floor." This is the scratch mark left by the deceased in a panic, with the thumb pointing down. It shows that he entered the elevator backwards. And when he faced someone, he was pushed down. ”

After listening to the words of my colleague, I pondered for a while and said to Xiao Su: "The deceased should have been pushed down in a reluctant farewell with someone." ”

After hearing this, Xiao Su nodded at me, and went to the property to ask for the information of all the residents in this building. After a while, Xiao Su came back with a document book and said to me: "All the information of the residents in this building is here. ”

I took the notebook and looked at it carefully for a while, and said, "That's not right, why are all the 12 floors empty?" ”

Xiao Su seemed to know that I would ask this, so he explained to me: "Oh, there are three households on the first floor. The residents of 1201 and 1203 have gone abroad and have also registered their houses for rent at the property. 1202 is a newlywed couple who went out for their honeymoon a week before the accident. ”

After listening to Xiao Su's words, I began to be silent, since the entire 12th floor is empty, who will the deceased go to see on the 12th floor?

Seeing that I didn't speak, Xiao Su said, "Is there something I missed?" Isn't the check detailed? ”

I shook my head and said to Xiao Su, "I was thinking that there was no one on the 12th floor, what did the deceased do there." Could it be that the murderer is in the residents of this building? Let's look into them one by one. ”

After Xiao Su and I agreed, we began to screen the suspects from the residents of this building......

After a day of investigation, I finally got a clue.

"On the 15th floor, there lives a single woman named Wang Shanshan, who is twenty-nine years old this year. The information shows that she and the deceased Zhang Guozheng used to be from the same unit and were cashiers. The only person who can talk to the deceased in this building has an intersection with this woman, and there is one on the 14th floor who is in the same unit, but it doesn't seem to have anything to do with the deceased. Xiao Su truthfully reported the investigation to the captain.

After listening to this, the captain said: "Then bring this woman over for interrogation, and besides, you two have not checked how others know that I am a policeman, and posted the report letter on my doorstep." ”

I shook my head at the captain and said, "It's better to check this woman's background first, after all, one is in her sixties and the other is in her twenties." If she didn't do this, it would have a bad impact on people's reputations. ”

Unexpectedly, as soon as I finished speaking, the captain smiled evilly and said to me, "You don't understand. It's not easy to forget the year, and the old husband and young wife are the most hilarious. Surely this woman has something to do with the deceased. Alright, you two go check it out. ”

After the captain finished speaking, he sat on the chair and picked up his mobile phone to fight the landlord. Xiao Su and I left the office and went directly to the deceased's unit before he retired......

When the deceased died, after Xiao Su and I entered the guard room, Xiao Su said, "Hello, we are friends of Wang Shanshan, and we want to come over ......."

Before Xiao Su finished speaking, he was interrupted by the doorman: "Don't fool me, I know what you two are doing." Don't look at me now, I'm also a factory director, and I look at people. Now that Lao Zhang is dead, are you here to find out what happened between Lao Zhang and Xiao Wang? ”

When Xiao Su and I heard it, there was really a connection between the two. Xiao Su asked, "Can you tell me more about what's going on?" ”

The doorman said: "The year before last, our factory bought 10 suites in the community where Lao Zhang and Wang Shanshan lived. This is the last welfare room, so the factory employees are staring at it, but there are only ten places. Many middle-level cadres were not allocated. ”

After listening to this, I asked a little puzzled: "You said that many middle-level cadres have not been assigned rooms, but Zhang Guozheng and Wang Shanshan." One is a retired workshop director, and the other is an ordinary cashier, how did they get the house? ”

After listening to my question, the doorman smiled and said, "Then you don't need to ask, Lao Zhang's son is the current factory director." Lao Zhang and that Wang Shanshan...... Got it. ”

After listening to this, Xiao Su and I looked at each other and smiled. Xiao Su said to me: "This time I really let the leader go, and I was blinded." ”

Xiao Su and I saw that things were basically the same, so we got up and said goodbye. After Xiao Su and I left the deceased's unit before retirement, we did not go back to the police station, but went directly to the home of that Wang Shanshan......

Xiao Su and I came to Wang Shanshan and knocked on the door, and Wang Shanshan seemed a little overwhelmed and said, "Who are you?" Who are you looking for? ”

Xiao Su took out his ID and said, "Police, let's find out more about the situation." ”

Unexpectedly, she said to Xiao Su: "I'm sorry, I don't have time." The police can't just disturb the normal life of the residents, I'm not available. ”

She was just about to close the door when I saw a man walking by, and I said, "Oh, no wonder there's no time, there's a guest." ”

The other party said to me coldly, "I love people." ”

At this time, the man in the house came over and said, "Shanshan, there are guests, then I'll go wash the vegetables." With that, the man turned and went back to the house.

When I saw the man leave, I asked Wang Shanshan, "When are you free?" ”

The other party thought for a while and said, "Tomorrow at noon, half past eleven, you can come to my house." ”

Xiao Su and I listened to each other's words and left the 15th floor......

Xiao Su said to me, "Isn't she single? Why do you have a husband? ”

I glared at Xiao Su and said, "She now has a motive to kill, she has an ambiguous relationship with the deceased, and she has a man who loves each other." Let's wait for tomorrow at noon. ”

Xiao Su and I agreed on the next day's time and then went home, waiting for the next day to talk to this Wang Shanshan at noon......

"I didn't have the time to commit the crime, and I went to our colleague's house on the 14th floor at 11 o'clock that night. Until one o'clock. "We came to Wang Shanshan's house, and Wang Shanshan said to me and Xiao Su.

After she finished speaking, I did not reply to her, but after observing the environment of her home, I said to her, "Your house has just been renovated, right?" ”

Wang Shanshan asked me a little at a loss, nodded and said, "Yes." ”

After I saw her answer, I pulled Xiao Su up and prepared to leave, and Xiao Su didn't understand why I was so abnormal today, so I followed me obediently for some reason. After I walked out of Wang Shanshan's house, I turned back to Wang Shanshan and said, "Listen to your wedding on the 28th of this month?" ”

As I said that, I could clearly feel an unnatural look on her face. She said to me, "Yes, I invite you to come if I have time." ”

After leaving Wang Shanshan's house, I asked Xiao Su to go to the 14th floor to verify whether Wang Shanshan's words were true or false, and Xiao Su soon had a clue......

"I asked Wang Shanshan's colleague, and she was indeed at her colleague's house. Watch TV together. However, according to her colleague's husband, she seems to have been out for about three or four minutes. ”

After listening to Xiao Su's words, I began to simulate running from the 14th floor to the 12th floor of the elevator. After countless experiments, I began to shake my head, even I could not guarantee that I could complete this series of actions in three to four minutes to push the deceased into the elevator back and forth between two floors, let alone a woman?

Xiao Su watched me run over and over again, and she said to me slowly: "This Wang Shanshan used to be a sprinter, she should be able to do it, now the only thing to do is to apply for a search warrant to check if there are any clues in her house to prove that she has done things in the elevator." ”

After Xiao Su finished speaking, I hurriedly scolded: "Damn, eldest sister, you already have a clue, can't you tell it earlier?" ”

Xiao Su quickly applied for a search warrant, and we found a hacked Trojan horse in Wang Shanshan's home computer......

In the interrogation room, I said to the suspect, "I'm sorry I can't attend your wedding." But I still admire you, I asked a technician to study your Trojan. You hack the Trojan into the property's elevator management system. That night, after the elevator system automatically shuts down, only 12 floors can be buttoned, you are a genius. ”

After I finished speaking, the rest of the interrogation was handed over to Xiao Su......

According to her own confession, she had a relationship with the deceased in order to get the welfare housing in the factory. But then she had the man she loved and wanted to cut off contact with the deceased, but the deceased was still pestering her, and finally she was afraid that her boyfriend would find out about the matter between her and the deceased, so she changed the elevator program through a hacker Trojan and designed this elevator killing. ”

Xiao Su told me the results of the criminal's own confession. I listened and fell silent. The program can be rewritten, but life can't, as long as you take a wrong step, you can't rewrite it......
