Sun Xiuming sat in the office all day uneasy, picking up and putting down the phone, putting it down and picking it up again, not knowing who to call.

When I'm old, I only go to the police when there is a big case - it's too difficult for a person in his forties to chase a thief - he usually sits in the team, responsible for registration, interrogation, and light work such as bringing new people, although the official position is not big, but the seniority is there, and he is also a person with prestige.

Sun Xiuming wanted to find someone to discuss Sun An's affairs, but he wasn't sure who to turn to, some of his colleagues in the past had been promoted, some were in other departments, and some had lost contact, and he couldn't figure out who he could trust and who he couldn't.

The cooperation between the police and criminals is nothing new, informants are criminals, but none of them are serious crimes, reporting to the police is considered to be atonement, Sun An personally admitted that he killed someone, this is a felony, it is impossible for a murderer to be an informant, unless the level of the person to be arrested is very high, even a homicide is nothing.

Sitting at the end of the day, Sun Xiuming didn't go back, sitting in the office smoking one cigarette after another, until the cigarette butt was dragged like sunflower seeds, then he got up, changed his clothes, went to the criminal police detachment, ate a bowl of noodles, and then came to the apartment building again.

"To be honest, I don't have a reason to cooperate with you, and I don't know if others are reliable, so I don't dare to contact casually. He also sat down on the stairs, sat next to Sun An, and took the cigarette that Sun An handed over.

Sun An nodded in understanding: "You and I really can't get too much benefit from cooperating, the patrol police are not the ones who convict and punish crimes, to be honest, my main partner is not you, it is the police of Qingji, you are just the breakthrough I chose, but people live for a lifetime, it is inevitable that they will encounter some problems that they can't solve, you don't need to cooperate with me as a policeman, just as a private person, I can help you solve the problem." ”

"Private identity...... I don't have anything I want, just mess around and get into retirement and eat retirement salary. Sun Xiuming said with a cigarette.

"No desire, no desire, this is the rhythm of becoming a Buddha?" Sun An said with a smile, and asked again, "Tell me why you can't be promoted, after so many years as a policeman, even if you don't have merit, at least you can be promoted to a squad leader or something, but you are still an ordinary police officer, you must have made some mistakes." ”

Sun Xiuming snorted his cigarette and said slowly: "It's not a big deal, when I was young, when I smashed those organized crime groups, I just killed the wrong person, in the process of arresting, I thought that guy was going to pull out a gun, so I shot that person to death, but he just jumped over the wall in a hurry, trying to throw away the drugs in his pocket, originally this manslaughter was not a big deal, at most he was given a punishment of probation, but it was an important witness, he died and failed to convict several leaders, and the result was either to stay in office, archive, You must not be promoted, or you will have your files destroyed, leave your job, and find a new job. ”

"It's really not a big deal, you're just a bad guy. Sun An nodded, this kind of thing may be encountered by the police, arresting the most vicious criminals, usually you are alive and dead, suspecting that the other party is pulling out a gun, and you are still stunned and don't shoot, you are dying.

"It's good to be a policeman, but I'm still a civil servant, I just can't be promoted, and I didn't want to be a big official, so I chose to stay. Sun Xiuming chatted with a man of age who could be his own son, like an old friend.

"But after making such a big mistake, you can still have a choice, you should also have some background, right?" Sun An turned his head to look at Officer Sun and asked.

Sun Xiuming shook his head: "It can't be regarded as having a background, the police family, my grandfather, my father's past colleagues, and students are basically big officials, so I stayed after saying hello." ”

"Since you don't want anything, then recommend a breakthrough, I'll go to him myself, and I won't involve you. Sun An saw that the reason why the other party didn't want to cooperate with him was that he was afraid of losing his job, which was also understandable.

"There's no hurry. Sun Xiuming opened the briefcase, took out a file from it and handed it to Sun An, and said, "If you can help solve this case, I will cooperate with you, and contact those people I know to persuade them to cooperate with you." ”

"It's going to be a problem. Sun An frowned and took the file, opened it and looked at it, and asked, "Cold case?"

Cold cases usually refer to cases that have not yet been solved, are about to be or have passed the prosecution period, and it is not easy to convict, and the slightest mistake in human and physical evidence will be caught by the defense lawyer, resulting in the failure of the prosecution, and the police have many such cold cases in their hands, and the longer the time, the more difficult it is to crack.

Almost every police officer will encounter such a case, sometimes because he is too involved and unable to solve the case, he ends up leaving a hole in his heart that he can't let go of until he dies.

Sun Xiuming nodded: "The case I encountered when I was young, the evidence was conclusive, but unfortunately it was polluted, and in the end, that guy was acquitted." ”

The file records a homicide case, the victim is a seventeen-year-old girl named Wang Min, the suspect is her classmate Yang Lei, the murder weapon is a fruit knife, the fingerprints on the handle have been wiped off, but the fruit knife has no hammer, when it stabbed into the girl's body, the suspect's hand slashed forward, the root of the blade cut his fingers, and the suspect's blood was collected at the place where the fruit knife handle was connected.

However, because the blood samples collected were contaminated in the process of handling the case, and there was no other evidence or witnesses, the suspect was released in court.

This file was asked for by Sun Xiuming when he went to the criminal investigation detachment just now.

"What do you want me to do?" Sun An closed the file and handed it back to Officer Sun.

"I just want you to help me ask him if he killed that girl. Sun Xiuming said calmly.

"If so, after the acquittal, he should have a fluke mentality, and he will commit it again, right, and then there will be no case?" Sun An asked.

Sun Xiuming shook his head: "There is no case with the same modus operandi, it has nothing to do with him, and I won't investigate him, and then I don't know much about that file." ”

"Is he still in Qingji?

"In. Sun Xiuming said an address.

"Okay, you go back, I'll leave it to me, I promise to satisfy you. Sun An stood up and moved his body.

Officer Sun left uneasily, this is already a risk, if Sun An fails, then the matter may eventually be traced back to him, but in order to fill the hole in his heart, this risk is still worth taking.

Sun An returned to the house, put on his coat, and put on his hat.
