Chapter 944

After finishing the notes, Lu Zhicun left.

Of course, although Han Bin subjectively thinks that his suspicion is not big, but still want to send someone to verify his alibi.

The lower the mistakes, the less we can make them.

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

Han Bin roughly looked over, "what do you think about his confession?"

Zhang shungu said, "from the time I started to contact him to give him a confession, he has been acting normally and didn't feel that there was a big problem.

Qi Shanghai said, "I also think his performance is normal, and the alibi is relatively complete, but one thing I don't understand is why the suspect stole his mobile phone and what's the purpose?"

Han Bin thought, "if my guess is good, the suspect steals his mobile phone, and uses his mobile phone to call the victim, just to cheat the victim's door?"

Qi Shanghai asked, "why do you have to use his mobile phone? What's the special reason? "

Han Bin said, "today's technology is more and more developed. When you answer a phone call, your mobile phone will automatically identify the number. If you are familiar with someone, your name will be displayed. If it's a stranger, it's also a stranger. If it is advertising, marketing, fraud, express, some mobile phones will also have tips.

Lu Zhicun is a courier. When he makes a phone call with his mobile phone, the person who receives the call will be prompted for the identity of the courier. At this time, the victim will lower his vigilance and naturally open the door to take the express.

As soon as the door opens, the suspect will control the victim as soon as possible. "

Feng Na asked, "the victim still has a dog at home. When the suspect is controlling the victim, what will he do if he attacks him after that?"

Han Bin said with a smile, "this problem is easy to explain. Dogs are lively in nature and are not suitable to be raised in buildings. In addition to some very lazy or obedient dogs, other dogs will be very excited when they hear the door opening or meet outsiders, and even run out of the door when the owner is not prepared.

I have a friend who also owns a dog. His dog has this kind of problem. If someone comes to the door or a courier, he usually locks the dog in the bedroom first and opens the door after he has finished the express delivery.

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

Zhang shungu pushed back along Han Bin's way of thinking, "team Han, how does the suspect know that the victim must have express delivery? If there is no express, he will 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 by express delivery. As long as you don't give him enough reaction time, he can't be sure whether it's his express delivery or not.

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

Of course, I'm not so easily subdued. "

Han Bin agrees, "yes, the victim likes online shopping, so the suspect gives him express delivery, which is exactly what he wants. This also shows from another angle that the murderer knows the victim very well. "

Qi Shanghai showed a look of admiration, "fierce, worthy of the Korean team, your explanation, so that the whole crime process is clear."

Zhang shungu then said, "yes, team Han, you have to come to our team often in the future, so that our business level can be improved."

Feng Na echoed, "that is, team Han, whether our ability to handle cases can be improved depends on you."

In the face of three people's flattery, Hanbin some laughing and crying, "OK, as long as you are not afraid of my arrangement of tasks, I'm willing to come more."

"Look what you said. You're trusting us when you arrange the task. We can't wait." Qi Shanghai is another flattery.

"I'll take it seriously." Han Bin said solemnly, "Lu Zhicun's alibi still needs to be checked. This task is up to you. In addition, check whether the victim He Jun likes online shopping. Is there a problem? "

"No

"Guaranteed to get the job done."

Han Bin looked at his watch and said, "OK, it's late today. Let's get off work first, come early tomorrow, and then check."

He is very considerate of his subordinates.

……

The next morning.

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

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

Han Bin truthfully said, "the previous speculation is my analysis, there is no empirical evidence."

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 is that he deliberately disguised as a serial killer in order to protect the employer behind him."

"Yes."

Ding Xifeng took out a box of cigarettes and gave Han Bin one. He also lit a cigarette and took a puff. "If it's really murder by hire, there must be an employer, and the employer should be someone familiar with the deceased. Do you have any speculation about the identity of the employer?""The general conjecture is that it is nothing more than interest, love killing and hate killing. As for the specific suspect, it is still uncertain for the time being."

Ding Xifeng flicked the ash, "since there is no evidence, and it is impossible to determine the suspect, the speculation should not be disclosed for the time being. You can investigate in private, you are the direct person in charge of the case, and it is very convenient to operate. "

"I see." Han Bin answered and continued, "Captain, I also want to ask you to help me find out if there are similar cases of employment homicide in other areas. It's not limited to the Z-shaped sign. It's very likely that there is not a person behind the killer, and there may be other forms of crime."

"I know what you mean. I will communicate with the provincial department. If it's really an employment homicide as you speculate, there must be a tight organization behind the killer, so we must be cautious. "

"I'll be careful."

Ding Xifeng warned, "if you are a professional killer, you must have certain anti reconnaissance ability. It's not easy to find their whereabouts. I suggest that starting from the identity of the employer, there must be a deep bond between the employer and the victim. "

"I remember."

"Well, you go first. I'll let you know when there's news from the provincial department."

Han Bin responded and left the team leader's office.

After returning to his office, Han Bin draws a tree diagram of three cases on the whiteboard. Han Bin and Ding Xifeng share the same idea. He also thinks that they should start from the identity of their employers.

Han Bin listed all the people who had emotional disputes, hatred and interests with the dead in the three cases. These are the key targets of investigation. These people must have common channels to contact the killers. As long as their contact channels can be found, the case will become clea
