At half past one o'clock in the afternoon of Friday, people came, Liu Xunya and Director Gao came to the office, only Zhang Kai was alone in the office, and everyone else was upstairs in the office, and then understood the situation through monitoring and listening equipment.

After the two sat down, they just wanted to say a few words, Zhang Kai stretched out his hand to signal to stop and said, "Let's get down to business." Director Gao took a deep breath and said, "I'm sure you also know that a person has been charged with several crimes, but it doesn't necessarily mean that this person is guilty." After hearing this, Zhang Kai looked at Director Gao with a questioning expression and asked: "You should know this question best, shouldn't you ask me? This is obviously your area of expertise." ”

Director Gao said: "I know this, and I know it, but I think if it were you, what would you answer? What do you think?" Zhang Kai cleared his throat and said: "It's really useless to just be charged, if there is no evidence to prove it, it doesn't mean guilty." The senior director thought for a moment and said, "What if there is evidence? Zhang Kai looked at Liu Xunya next to him, what does that mean what are you here for? Liu Xunya said: "There is a person accused of stealing, and there is evidence, but we all know the person who this person is, and we all feel that it is definitely not him, if it is you, you are charged, and you find fingerprints and hair, do you have a way to get out." ”

Zhang Kai smiled and said, "Who is this person? Director Gao was silent for a while and said: "My brother-in-law, but he has always been an honest man, he can't do this kind of thing, after this incident, he was accused of honestly cooperating with the investigation, this is not the attitude of a criminal, there are too many suspicions, I believe it is definitely not him." ”

Zhang Kai looked at Director Gao and Liu Xunya, stood up and poured a glass of wine for himself, and looked at the two of them and said, "Would you like a drink?" Director Gao naturally shook his head, Liu Xunya wanted but didn't dare, so he didn't speak, Zhang Kai saw it, so he poured a glass of Gordon Gin and put it in front of her, Zhang Kai took his wine glass, sat down and took a sip and said, "Take me to see the fingerprints and hair on the evidence." ”

Director Gao had already prepared, opened the briefcase he was carrying, and took out a file folder for Zhang Kai, Zhang Kai looked at it, it was a bowl made of jade, Zhang Kai looked at it and said, "Is this picture being P, or is it just like that?"

Director Gao glanced at the picture and said, "That's it." Zhang Kai said: "Your brother-in-law was framed. Director Gao and Liu Xunya nodded at the same time and agreed with this view, Zhang Kai continued: " The fingerprints on this are too obvious, although you use the powder method and magnetic suction method to detect the fingerprints, but this is too complete, and this fingerprint is obviously the left hand and one hand, this is not your own dinner bowl, nor is it a bowl for rice, a priceless bowl, leaving such an obvious fingerprint is problematic, plus the fingerprint is obviously picked up with one hand, giving people a feeling of random loading, not the attitude that this jade should have, is your brother-in-law a rough person?"

The head of the high department leaked a disgusted expression and said: "How can it, he is very honest, he is embarrassed to talk to others, he always keeps his head down, if there is a woman to talk to him, he is nervous, his breathing will be short, his face will be red immediately, he is also timid, he is light on everything, and he is not a rough person at all." ”

After hearing this, Zhang Kai said, "What does your brother-in-law do?" Director Gao pursed his lips and said, "The ice cream is sold in the mall, the kind of big one, cup by cup." ”

Zhang Kai said as if he understood something: "So that's the case, call out all the surveillance, look at the monitoring screening, and then ask your brother-in-law if there are any guests who are suspicious." Director Gao took out a hard drive from his briefcase and gave it to Zhang Kai and said: "The monitoring is this, but it is a little damaged, and the people in their store are also very surprised, how can there be damage, can you deal with it?" Zhang Kai nodded and said: "Yes, even if I can't, there are other ways." ”

Zhang Kai let Director Gao and Liu Xunya go, after the two left, Zhang Kai handed over the hard disk to Zhao Tiande and Yan Xiaojing, the two took more than four hours to get it done, and the monitoring came out, the next day Zhang Kai took the monitoring to find Director Gao and Liu Xunya, and showed them a suspicious place, a woman, wearing a hat, wearing disposable gloves on her hands, grabbed the rim of the cup and bought a cup of ice cream, Zhang Kai said to Director Gao: "Ask your brother-in-law who this person is, do you have any impression." ”

Director Gao found his brother-in-law and asked, the brother-in-law couldn't remember, but if there was monitoring in other parts of the mall, he could also see it, and he could see who this person was, Director Gao told Zhang Kai about it, and planned to apply for an investigation to extract monitoring, Zhang Kai thought for a while and said: "No need, you wait for me, I'll be back in two hours." ”

Zhang Kai called Zhao Tiande and Yan Xiaojing while walking out, telling Zhao Tiande that he was going to the mall, and the monitoring room of the mall might not have a network, so he asked Zhao Tiande to get a network receiver for himself, and told Yan Xiaojing to prepare, once there was a network intrusion, call up the monitoring records and return them to his computer.

Zhao Tiande came to the back door of the mall, carrying a bag, which has network equipment, which can connect to the network in nearby places, Zhang Kai followed Zhao Tiande to the back door of the mall, the back door is usually guarded by security guards, but it doesn't matter who comes in and out, there are many tenants and employees, and many people who have been working for three or five years do not know, so the back door security guards usually occasionally help people unload and load, and they don't care about anything else.

The back door is very messy, there are a lot of small carts loaded with goods, next to the electrician's room, the monitoring room is not far from the electrician's room, Zhang Kai took Zhao Tiande's bag down and carried it on his back, pointed to an electrician's overalls on the cart next to him and said: "Tiande, put it on." Zhao Tiande put it on, and the two walked into the monitoring room, and there was a person on duty inside who looked at Zhao Tiande and Zhang Kai and said, "What's wrong?" Zhang Kai said: "I'm new here, follow the master to learn, the master will not do it in two days, and he will leave after the handover, come to learn whether there is anything to repair and maintain in the monitoring room, don't be in case the master leaves, I won't, and no one will teach me." The person on duty looked at Zhao Tiande, who was wearing uniform, and then looked at Zhang Kai and said, "Oh, then you can take a look, how do you get it?" Zhao Tiande looked around and said: "There's nothing to do, there are not many things in the monitoring room, you mainly remember the points I just told you, do you know?" Zhang Kai nodded.

The person on duty also had nothing to say and said, "Why did you stop doing it well?" Zhao Tiande pretended to say: "Alas, it's boring, I've done enough, and I'm panicking when I stay here all day." The person on duty looked at Zhao Tiande and said, "You haven't been doing it for long, haven't you seen you before?" Zhao Tiande took out a cigarette and said: "I used to be in the supermarket opposite, I felt that the environment was not good to come here, but I didn't expect it to be as good as there." The person on duty took the cigarette and said, "No way, it's all like this, those of us who watch the monitoring don't have this environment." ”

Zhao Tiande smiled and said, "Yes, I haven't seen the light of day all day, let's go, go outside and smoke a cigarette." The person on duty looked a little embarrassed, meaning that he was watching from inside and what to do when he left.

Zhang Kai said: "Then you can smoke it, I'll go back." The man on duty said, "Why don't you smoke?" Zhang Kai showed a little embarrassed expression and said: "I won't, you two go and smoke, I'll wait for you two here, I'll call you if there's something, and I'll smoke it back if it's okay." The person on duty thanked him a few words and left, Zhang Kai put down the bag, turned on the network equipment, and sent a message to Yan Xiaojing to say action, five minutes later, Zhao Tiande came back with the person on duty, Zhang Kai put the bag on the ground, sat on the stool, held his cheeks, and pretended to be very bored, the person on duty saw Zhang Kai like this and said, "It's boring." Zhang Kai nodded, chatting with others, after more than 20 minutes, Zhao Tiande's mobile phone rang, and after looking at it, he said to Zhang Kai: "You can get here today, you can get off work, go home and rest, and then think about it, if you want to come, call if you want to come." ”

Zhang Kai stood up and left with his bag, Zhao Tiande came out, took off the electrician's jacket and put it in the original place, and walked out, the security guard didn't know where to play at this time, just came back, saw Zhao Tiande walking out and said, "Off work?" Zhao Tiande nodded and said, "Middle class?" The security guard smiled and snorted.

After walking out of the road, I got out of the car and drove Zhang Kai to find Director Gao, on the way Zhao Tiande said: "Brother Kai, I learned badly from you, and now I am very calm when I lie and deceive people, as if it is very normal." Zhang Kai smiled and said, "This is your talent." ”

When the police found Director Gao, Director Gao was about to go out, and saw Zhang Kai and said, "My application has been approved, and I want to go to the mall to see the surveillance, are you coming?" Zhang Kai raised his hand and said, "I have found it." ”

Director Gao was stunned, how did he get it? Without saying anything, Zhang Kai said, "Go to your office." After arriving at the office, Zhang Kai asked Yan Xiaojing to send the matched video file remotely, and after opening it, he found the day that the senior director's brother-in-law said, the video of the same time, and found this woman after opening it, it was the cashier on the second floor of the mall, leaving the video data, and Zhang Kai left.

Not long after, the case was solved, the cashier was just a scapegoat, met a man, this man asked the cashier to do this, the two were boyfriend and girlfriend who had just met, the cashier was arrested, the police immediately told the whole situation, this man is also big-hearted, thinking that this is seamless, and he will not have a problem, but Skynet is restored and not leaked, and he was quickly arrested.
