"Drug trafficking, human trafficking, forcing good people to become prostitutes, scum. Ye Shikai looked at the file bag handed over by Song Tian, which carefully wrote the details of this escaped prisoner, the escaped prisoner's name is Xun Long, known as Long Ye, he was a well-known drug lord in the past, he was involved in all kinds of pornography, gambling and prostitution, he used to do all kinds of evil in southern China, and at the same time there was a very powerful force underneath.

However, in the past few years of the country's crackdown activities, this force has been seriously shrunk, and it was in the previous month that the police and the military jointly operated to arrest Xun Long in a drug factory, and brought him back to Yanjing for trial.

"Uncle Song, why is there only his criminal record on this Xun Long's file, but there is no basic information from before. Ye Shikai asked, hearing this, Song Tian also sighed helplessly, shook his head and said, "This kind of person, how can he leave so much information from the police to check him." ”

Ye Shikai nodded, a person like Xun Long is like a rat in the sewer, he will escape at the slightest disturbance, otherwise the police would not have spent so much energy to catch him.

"Okay, leave it to me, I'll do my best. Ye Shikai said to Song Tian, when he was in the army before, Ye Shikai had learned top investigation methods, if you want to talk about the ability to investigate the scene, Ye Shikai will throw off those policemen for several streets, and Song Tian is Ye Shikai's father's comrade-in-arms, so it is reasonable and reasonable, Ye Shikai is duty-bound.

"Okay, I'm sorry for the trouble. Song Tian smiled with relief, and then led Ye Shikai to the scene, with Song Tian as the director, now everyone is very humble to Ye Shikai, Ye Shikai's questions, they also have to answer questions, if it weren't for the stunned police officer just now, Ye Shikai may not be as smooth as now.

"Hey, you don't see anything. After an hour, Zhang Ting couldn't sit still, so she hurriedly came over and asked.

"Don't worry, it's so easy to investigate the site. Ye Shikai looked carefully at the traces on the ground, and couldn't help muttering, "It's either playing with guns or knives, it's so fierce, let's see how you get married in the future." ”

"Bastard, what are you talking about. Zhang Ting, who had sharp ears, said, and immediately went crazy like a cat that stepped on its tail.

"Don't argue, believe it or not, I'll tell Song Bureau. As soon as Ye Shikai said it, Zhang Ting immediately became well-behaved, but she still gritted her teeth, who called Zhang Ting a handle, "Okay, I'm done investigating." After more than ten minutes, Ye Shikai said.

"yes, did you find anything. Zhang Ting impatiently pulled Ye Shikai's arm and kept shaking.

"Nothing was found. Ye Shikai smiled slightly, took a glass of water from the table, and drank it in a big gulp, Zhang Ting's face was almost blue with anger, both fists were clenched, what about the master, what about solving the case one day, a murderous aura emanated, and the police officers next to him slipped away silently.

"Don't mess around, I'm not done yet. Ye Shikai looked at the stick tightly held in Zhang Ting's hand, with a black line on his face, and said with a sly smile, "I didn't find anything, but it was the biggest discovery." ”

"What does that mean. Zhang Ting asked suspiciously, looking at Ye Shikai puzzled.

"I didn't see any traces of this scene, it was like no one had ever been there. Ye Shikai said slowly, "However, as long as it is a person, it will leave some traces more or less, but there is nothing here." ”

"Could it be that the ghost helped him escape from prison? Zhang Ting said, Ye Shikai's face was black, and a chestnut hit Zhang Ting's forehead.

"Stupid, where did the ghost come from, there is no trace at the scene, it is the biggest trace, and it is also the fatal part of this criminal, because no crime is perfect, and this criminal is so perfect that it is suspicious. ”

"What the hell do you mean. Zhang Ting was nervous, she really didn't know what Ye Shikai meant, Ye Shikai looked around, looked at the surrounding police, and directly grabbed Zhang Ting's arm and pulled her into an interrogation room.

"Is this room soundproofed. Ye Shikai said.

"Soundproof. ”

"Okay, let me ask you, since the month when Xun Long was arrested and brought to the police station, has there been any changes in your police station, such as office positions, or character changes. Ye Shikai asked.

"The officer's office location and some key areas, but there is no change, as for the personnel, I remember, the cleaner who has been responsible for cleaning the police station, one day asked for leave for business, but the next day came back, nothing unusual. Zhang Ting thought about it for a long time, and finally remembered.

"That's probably the problem. Ye Shikai said, "Is there really no abnormal behavior after he came back?" ”

"No, after he came back, the cleaning work was not leaky, and there was no need to rush, and the work every day was like a ......"

"There won't be any deviations from the robot, right. Ye Shikai interrupted Zhang Ting's words, and Zhang Ting showed an expression of sudden realization.

"If you are an ordinary person, no matter how careful you are, it is inevitable that there will be mistakes when working, but only a real killer can do it without leakage, and his mistake is to make all this too perfect, unintentional mistakes are inevitable, and it will not be unintentional. Ye Shikai's face showed a confident smile.

"And in the past month, the place where Xun Long is held has not changed, only those who have been lurking in the police station for a long time can be familiar with the branch composition of the police station, and can perfectly unlock and escape from prison, and this, as a cleaner, he will definitely be able to do it. ”

"I see what you mean. Zhang Ting stood up excitedly and slammed the table.

"I guess correctly, the original cleaner is dead, and the later one is just an impostor. Ye Shikai said lightly.

"What, it turns out that the criminal has been in the police station all along. Zhang Ting looked ashamed, this bold criminal has been moving under his nose.

When the two left the interrogation room, Zhang Ting directly grabbed a police officer's collar and said loudly, "What about the cleaner." ”

"Well, Sister Ting, he's ...... Resigned and left. The police officer was so frightened by Zhang Ting's actions that his words were incoherent.

"Damn. Zhang Ting scolded.

"Don't worry, you give me the address of that cleaner, and we'll go there now. Ye Shikai patted Zhang Ting's shoulder and comforted.
