"Han Bin, let's talk about it first, Detachment Ding has praised you a lot in front of me. ”

Ding Xifeng is the deputy head of the criminal investigation team of the Qindao Public Security Bureau and the captain of the municipal criminal investigation team.

In private, Ma Jingbo will call the other party's captain, and in front of outsiders, he will call the deputy detachment leader.

At different times, it is still very particular to use different names.

It's not the first time Han Bin and Ma Jingbo have met, and the two have also cooperated in the 101 project, and Han Bin is no stranger to him.

"I think it is best to locate a suspicious mobile phone number, and if it can be located to the current location, it is naturally the best; if the mobile phone number is not in the service area, you can locate the location of the last call of the mobile phone number, and the suspect must have appeared nearby, and maybe there will be any evidence left." ”

Han Bin's proposal is not very clever, but it is the most direct way to find the suspect.

Ma Jingbo nodded: "Wang Xiao, call the technical team of the city bureau in a while, and ask them to contact the people of the communication company to locate the location of the suspicious mobile phone number." ”

"Yes. ”

"What else do the others think?"

"Ahem......"

Li Hui cleared his throat: "You should contact Zhao Xiaoshan's family in time to determine whether Zhao Xiaoshan is really missing, if it is determined that Zhao Xiaoshan has disappeared, the family can also provide some clues before the disappearance." ”

"Li Hui, yes, that's right. ”

Ma Jingbo added: "Not only Zhao Xiaoshan's family, but also the family members of the first two victims, Ren Jianhua and Cao Da, should also be notified, let them come to the substation to make a record, and then cross-compare their records to see if they can find common clues." ”

"The remains of two deceased people were found in the stomach of the dog, one of whom was identified by DNA comparison as the second missing person, Cao Da, but the identity of the other deceased could not be determined. My guess is that the other deceased is likely to be the first missing person, Ren Jianhua, so when notifying Ren Jianhua, it's best to ask an immediate family member to come over. ”

"That's the way it is now, I'll arrange the task. Ma Jingbo said this, and ticked it on his notebook: "The location of the mobile phone and the tracking of the suspect will be handed over to Captain Zeng." ”

"No problem. Zeng Ping said.

Ma Jingbo pointed to Wang Xiao on the side: "You have to assist Captain Zeng in his work, in the process of tracking down the suspect, once you exceed the jurisdiction of the Yuhua Branch, you will investigate in the name of the Municipal Criminal Investigation Team." ”

"Yes. Wang Xiao responded.

The Municipal Criminal Investigation Team has law enforcement powers throughout Qindao, which is much more convenient than the Criminal Investigation Team of the Yuhua Branch.

"Captain Ma, it takes a certain amount of time to locate the mobile phone, I want to go to Zhao Xiaoshan's house to see if there are any clues. Zeng Ping proposed.

"Wang Xiao has Zhao Xiaoshan's information, you can ask him directly. Ma Jingbo said.

Zeng Ping nodded and left the conference room with Wang Xiao, Li Hui and others.

After seeing Zeng Ping and others leave, Han Bin suggested: "Captain Ma, since Zhao Xiaoshan may still be alive, I suggest starting with him first, maybe you can find some valuable clues." ”

"I think so too, the other two cases are far away, Zhao Xiaoshan only disappeared yesterday, and the clues left are easier to investigate. Ma Jingbo agreed.

Han Bin continued: "Then I will notify the technical team and ask them to contact the communication company and print out Zhao Xiaoshan's communication records. ”

Ma Jingbo waved his hand: "Let me contact the technical team of the city bureau, they have always cooperated with the communication company, and the procedures are simpler." ”

Han Bin was also happy: "Horse team, what are we going to do now?"

Ma Jingbo glanced at Han Bin, Zhao Ming, and Tian Li: "If the three victims are all confirmed, what do you think the murderer's purpose is?"

Zhao Ming touched his chin: "These three victims are all young men, will it be a revenge killing, just like the first victim of the snowman case, these three young men are all substitutes for someone." ”

Ma Jingbo took over the conversation: "I have read the file of the Snowman case, the murderer of the Snowman case is not a standard serial killer, if you guess that the murderer of the 131 case is more mature than the murderer of the Snowman case." ”

Han Bin also agreed with Ma Jingbo's words that the first victim of the snowman case was a substitute for the murderer's wife. But the second victim was for revenge.

If the murderer of the Yeti case is not caught, he continues to kill, and it is likely that he will continue to find a replacement for his wife, and he will evolve into the murderer of the 131 case, becoming a standard serial killer.

Once there is no element of revenge, there is no direct connection between the murderer and the victim, and the murderer is likely to take a look at the victim on the street and treat the victim as the next substitute.

In this case, it will increase the difficulty of the investigation.

The mask was a little uncomfortable, and Han Bin shrugged the mask: "Zhao Ming's guess has a certain possibility, but now we know too little about the situation, and we can't clarify the nature of the case." ”

Taking advantage of the discussion of the case, the four of them each made a bowl of instant noodles and a ham each, which was considered today's lunch.

In order to avoid mutual infection, when eating instant noodles, each of the four people is separated by a distance of two meters.

The efficiency of the technical team of the municipal criminal investigation team is really higher than that of the technical team of the sub-bureau, and as soon as the four of them finished eating instant noodles, Zhao Xiaoshan's communication record was sent to Ma Jingbo's WeChat.

The public security system does not have the phone numbers of Zhao Xiaoshan's relatives, so it can only find out the more common contacts through Zhao Xiaoshan's communication records.

After some comparison, Han Bin found a number that called Zhao Xiaoshan most frequently and dialed it.

"Hey. "There was a woman's voice on the phone, and it didn't sound very old.

Han Bin didn't know the identity of the other party, and said tentatively: "Is Zhao Xiaoshan here?"

"Who are you?" the woman asked rhetorically.

"Isn't this Zhao Xiaoshan's mobile phone?"

"I'm Zhao Xiaoshan's girlfriend, and I'm also looking for Zhao Xiaoshan. The woman said.

"What's your name?"

"My name is Ning Yuerong, who are you, why did you call me?"

"I'm from the criminal investigation team of the Yuhua Branch, and I want to know something about Zhao Xiaoshan's situation with you. ”

"What's wrong with Xiaoshan, I'm looking for him too, what's wrong with him?" Ning Yuerong's tone was a little anxious.

"When was the last time you contacted Zhao Xiaoshan?"

"Yesterday morning, we were still on the phone. Later, his mobile phone was shut down, I couldn't be contacted, and he didn't reply to WeChat, I was always worried about ......" Ning Yuerong cried:

"Comrade policeman, what's wrong with Xiaoshan?"

"Based on what we know so far, Zhao Xiaoshan is likely missing. ”

"Missing? how could he be missing, was he kidnapped, or whatever. ”

"His specific situation, our police are also investigating, do you have the contact information of his parents?"

"Nope. ”

"Do you know where he lives?"

Xiaoshan didn't live with his parents, he lived alone, in Room 702, Unit 2, Building 1, Baiziwan Community, Guangrong Road. ”

"Do you have the keys to the house?"

"Yes, yes, I can take you there. ”

"Well, we're just trying to make a note for you. ”

"Half an hour later, we met at the east gate of Baiziwan Community. ”

"Yes. ”

"Comrade policeman, what do you call it?"

"My surname is Han. ”

After hanging up the phone, Han Bin said to Ma Jingbo on the side: "Captain Ma, do you want to continue to check the mobile phone numbers of Zhao Xiaoshan's parents from the communication records." ”

Ma Jingbo clasped his hands to his chest: "Since Zhao Xiaoshan has the most calls with this Ning Yuerong, it proves that the relationship between the two is very close, and he knows the most, let's rush to Baiziwan Community now, and you can check the mobile phone numbers of Zhao Xiaoshan's parents in the car." ”

Subsequently, Han Bin and his entourage got into the car, and when they were about to continue to find the mobile phone numbers of Zhao Xiaoshan's parents in the car, Li Hui called.

Zhao Xiaoshan's ID card had an address registered, and Zeng Ping and others searched for that address and found Zhao Xiaoshan's parents.

He is now making a transcript of Zhao Xiaoshan's parents.

This is equivalent to saving Han Bin and the others, they only need to contact Ning Yuerong.

Baiziwan Community.

There are a total of four doors in the Baiziwan community, three of which have been closed, only the east gate is still open, and the temperature must be measured when entering and leaving.

After arriving at the east gate of Baiziwan Community, Han Bin took out his mobile phone and dialed Ning Yuerong's number.

Then, from a white Tesla car, a woman walked down, wearing a gray mask, with a slim figure, dressed very fashionably, and it can be seen from the vaguely exposed eyebrows and eyes that she should look very beautiful.

Han Bin and the others got out of the car: "Hello, is it Ning Yuerong?"

"It's me, you're Officer Han. The young woman walked briskly. There was also a woman behind her, a little older, and she looked a little like Ning Yuerong between her eyebrows and eyes.

Han Bin pointed to Ma Jingbo next to him: "This is Captain Ma of the Municipal Criminal Investigation Team." ”

"Hello Captain Ma, I just called Xiaoshan again, but the phone still can't get through, let's go to his house and have a look." Ning Yuerong urged.

The woman next to her dragged Ning Yuerong and said to Ma Jingbo on the side: "Captain Ma, I am Ning Yuerong's mother, can I take a look at your documents?"

Ma Jingbo showed his police ID.

"Eh, it's actually a comrade of the Municipal Criminal Investigation Team, what happened to Zhao Xiaoshan, do you want to find him?" the woman said curiously.

Ma Jingbo looked at the other party: "What do you call it?"

"My name is Chen Xia and I work for the Municipal Women's Federation. ”

"We are investigating a case and suspect that Zhao Xiaoshan may also be one of the victims. ”

As soon as she heard this, Ning Yuerong suddenly became anxious: "What kind of case, what is the danger in Xiaoshan, Captain Ma, you quickly tell me, what is going on?"

Han Bin persuaded: "Miss Ning, don't be too excited, it's still only the investigation stage, and it may just be a false alarm." ”

Ning Yuerong left tears: "No, no, this is not the first time, Xiaoshan has already had an accident, I asked him to call the police, he refused, he is just too kind." ”
