Detective from The Future

After finishing the transcript, Lu Zhicun left.

Of course, although Han Bin subjectively thinks that he is not very suspicious, he still has to send someone to verify his alibi.

The more low-level mistakes, the less you can't make them.

Zhang Shungu handed over a document, "Team Han, this is Lu Zhicun's transcript."

Han Bin read it roughly, "What do you think about his confession?"

Zhang Shungu said, "From the beginning of my contact with him, to giving him a confession, he has always behaved fairly normally, and he didn't think there was a big problem.

Qi Shanghai said, "I also think his performance is normal, and his alibi is relatively complete, but there is one thing I don't understand. Why did the suspect steal his phone and what is the purpose?"

Han Bin thought for a while, "If my guess is good, the suspect stole his mobile phone and used his mobile phone to call the victim, just to deceive the victim's door?"

Qi Shanghai asked, "Then why do we have to use his mobile phone? Is there any special reason?"

Han Bin said, "Nowadays, technology is more and more developed. When you answer a call, your mobile phone will automatically recognize the number. If you are a familiar person, it will display your name. If it is a stranger, it will also display a stranger. If it is an advertisement, Sales, fraud, courier, and some mobile phones will also have prompts.

Lu Zhicun is a courier and uses his mobile phone to make a call. The person who receives the call will be prompted as the courier. At this time, the victim will lower his vigilance and naturally open the door and take the courier.

Once the door is opened, the suspect will control the victim as soon as possible. "

Feng Na asked, "The victim still has a dog at home. When the suspect controls the victim, what if he attacks him afterwards?"

Han Bin smiled, "This question is easy to explain. Dogs are more lively by nature and are not suitable for keeping in a building. Except for some particularly lazy or obedient dogs, other dogs will hear the door opening or see outsiders. He seemed very excited, and even ran out from the door when the owner was unprepared.

A friend of mine also raises a dog. His dog has this problem. If someone comes to the door or a courier, he usually locks the dog in the bedroom first, and then opens the door after he finishes the delivery.

The suspect can use this time difference to subdue the victim first, and then subdue the dog. "

Zhang Shungu followed Han Bin's thoughts and pushed back, "Team Han, how does the suspect know that the victim must have express delivery? If there is no express delivery, wouldn't he be exposed?"

Feng Na raised her hand, "I can answer this question. People who really love online shopping often buy things online, either by express delivery or on the way to take express delivery. As long as you don't give him enough time to respond, He also couldn't determine if it was his express.

If I were the victim, I might also open the door.

Of course, I am not so easily subdued. "

Han Bin agreed, "Yes, the victim likes shopping online, so the suspect will give him express delivery to his liking, which is just right. This also shows that the murderer knows the victim well from another angle."

Qi Shanghai showed a look of admiration, "Awesome, worthy of the South Korean team, your explanation has made the whole crime process clear."

Zhang Shungu continued, "Yeah, the Korean team, you have to come to our team often in the future, so that our business level can be improved."

Feng Na agreed, "That is, the Korean team, whether our ability to handle cases can be improved is up to you."

Facing the flattery of the three people, Han Bin was a little bit dumbfounded, "Okay, as long as you are not afraid of me arranging tasks, I would be happy to come."

"Look at what you said, you arrange the task, that is to trust us, we are eager." Qi Shanghai is another flattery.

"I'll take it seriously." Han Bin said sternly, "Lu Zhicun's alibi is still to be verified. This task is left to you. Also, check if the victim He Jun likes shopping online. Is there a problem? ?"

"No."

"Guaranteed to complete the task."

Han Bin glanced at his watch. It was already past seven o'clock in the evening, "Okay, it's late today, let's get off work first, come early tomorrow, and then check."

He is still very sympathetic to his subordinates.

...

The next morning.

After Han Bin arrived at the Municipal Public Security Bureau, he went to the captain's office and told Ding Xifeng of his speculation yesterday.

Ding Xifeng frowned, "Hire to kill? Do you have any evidence?"

Han Bin said truthfully, "The previous speculations are all my analysis, and there is no evidence yet."

Ding Xifeng stood up and walked for a while, "According to your guess, the reason why the killer left the Z mark on the dead was to deliberately pretend to be a serial killer in order to protect the employer behind him."

"Yes."

Ding Xifeng took out a pack of cigarettes and gave one to Han Bin. He also lit his cigarette and took a cigarette. "If it is really hired to kill, then there must be an employer, and this employer should be someone who is more familiar with the deceased. Regarding the identity of the employer Do you have any guesses?"

"There are general speculations. It is nothing more than interest, love killings, and vendettas. As for the specific suspects, it is temporarily uncertain."

Ding Xifeng flicked the soot, "Since there is no evidence and the suspect can not be determined, then this speculation should not be disclosed for the time being. You can investigate in private. You are the direct person in charge of the case. It is still very convenient to operate."

"I see." Han Bin replied and continued, "Captain, I would also like to ask you to find out if there are similar hired homicides in other areas, not just limited to the Z-shaped sign, it is very possible behind this killer. Not alone, it is possible to commit crimes in other ways."

"I understand what you mean, and I will communicate with the provincial government. If it is really like your speculation that this is an hired murder case, there must be a strict organization behind this killer and we must treat it with caution."

"I will be careful."

Ding Xifeng warned, "If you are a professional killer, you must have a certain degree of anti-reconnaissance ability. It is not easy to find their whereabouts. I suggest starting from the identity of the employer. The employer and the victim must have a deep bond."

"I remember."

"Well, you go first, and I will tell you when there is news from the provincial government."

Han Bin responded and left the captain's office.

After returning to his office, Han Bin drew a tree diagram of the three cases on the whiteboard. Han Bin and Ding Xifeng's ideas were the same, and he also felt that he should investigate from the employer's identity.

Han Bin listed people who had emotional entanglements, hatreds, and interests with the deceased in the three cases. These are the key targets for investigation. These people must have common channels to contact the killer, as long as their connections can be found. Channel, the case will become clear...
