Chapter 414

"Han Bin, first of all, team Ding praises you in front of me."

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

In private, Ma Jingbo will call the other party's leader and vice leader in front of outsiders.

It's very particular to use different names at different times.

It's not the first time that Han Bin and Ma Jingbo have met. In the 101 project, they also cooperated with each other. Han Bin is no stranger to him.

"I think it's the best way to locate the suspicious mobile phone number. If the mobile phone number is not in the service area, it can locate the last call place of the mobile phone number. The suspect must have appeared nearby, and may leave some evidence."

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

Ma Jingbo nodded: "Wang Xiao, I'll call the technical team of the Municipal Bureau later and ask them to contact the people of the communication company to locate the location of the suspicious mobile phone number."

"Yes."

"What other people think?"

"Cough..."

Li Huiqing cleared his throat: "we should contact Zhao Xiaoshan's family in time to make sure whether Zhao Xiaoshan is really missing. If it is confirmed that Zhao Xiaoshan is missing, his family members can also provide some clues before his disappearance."

"Li Hui, right? That's right."

Ma Jingbo added: "it's not only Zhao Xiaoshan's family members, but also the families of the first two victims, Ren Jianhua and Cao Da, who have to be informed to come to the branch office to take notes, and then cross check their records to see if they can find common clues."

"The remains of two dead people were found in the dog's intestines and stomach. One of the dead was confirmed to be the second missing person Cao DA by DNA comparison, but the identity of the other was still uncertain. I guess the other dead person is probably the first missing person, Ren Jianhua. So when we inform Ren Jianhua, it's better to let his immediate family members come. "

"That's the situation at the moment. I'll arrange the task." Ma Jingbo said that, in the notebook tick: "mobile phone positioning and tracking of suspects, to have team leader responsible."

"No problem." Zeng Ping Road.

Ma Jingbo pointed to Wang Xiao on one side: "you should help team leader Zeng well. In the process of tracking down the suspect, once you exceed the jurisdiction of Yuhua Branch, you will investigate in the name of the city criminal investigation team."

"Yes." Wang Xiao answered.

The municipal criminal investigation team has law enforcement power in the whole Qindao, which is much more convenient than the criminal investigation team of Yuhua Branch.

"Captain Ma, it takes time for mobile phone positioning. I want to go to Zhao Xiaoshan's home to see if there are any clues." Zeng Ping proposed.

"Wang Xiao has information about Zhao Xiaoshan. You can ask him directly." Ma Jing wave path.

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

After seeing Zeng Ping and others leave, Han Bin suggests: "Captain Ma, since Zhao Xiaoshan may still be alive, I suggest that we start investigating from him first, maybe we can find some valuable clues."

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

Han Bin continued: "then I will inform the technical team and let them contact the communication company to print out Zhao Xiaoshan's communication record."

Ma Jingbo waved his hand: "I'd better contact the technical team of the Municipal Bureau. They have been cooperating with communication companies all the time, and the procedures are simpler."

Han Bin is also happy and relaxed: "horse team, what do we do now?"

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

Zhao Ming touched his chin: "these three victims are all young men. Will they be revenge murders, just like the first victim of the snowman case? These three young men are substitutes for someone."

Ma Jingbo took over: "I've seen the files of the snowman case. The murderer of the snowman case is not a standard serial killer. According to your guess, the murderer of the 131 case is more mature than the murderer of the snowman case."

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

If the murderer of the snowman case is not caught, he will continue to kill, and will probably continue to find a substitute for his wife, which will turn into the murderer of the 131 case and become a standard serial killer.

Once there is no revenge factor, there will be no direct contact between the murderer and the victim. The murderer may look at the victim in the street and take the victim as the next substitute.

In this case, the investigation will be more difficult.

Han Bin shrugged his mask: "Zhao Ming's guess is possible, but we don't know much about it now, so we can't know the nature of the case."

Taking advantage of the time to discuss the case, each of the four made a bowl of instant noodles, and each of them had a ham, which was today's lunch.In order to avoid mutual infection, when eating instant noodles, four people are separated by two meters each.

The efficiency of the technical team of the municipal criminal investigation team is indeed higher than that of the technical team of the Branch Bureau. As soon as the four people finished the instant noodles, Zhao Xiaoshan's communication records were sent to Ma Jingbo's wechat.

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

After a comparison, Han Bin found a number with Zhao Xiaoshan to call the most frequently.

"Hello." A woman's voice came from the mobile phone. It should sound young.

Han Bin is not clear about the identity of the other side, probing: "is Zhao Xiaoshan there?"

"Who are you?" Asked the woman.

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

"I'm Zhao Xiaoshan's girlfriend. I'm looking for Zhao Xiaoshan, too." Said the woman.

"What's your name?"

"My name is Ning Yuerong. Who are you and why do you call me?"

"I'm from the criminal investigation team of Yuhua Branch. I want to know something about Zhao Xiaoshan."

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

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

"Yesterday morning, we were on the phone. Later, his mobile phone stopped working, and I couldn't get in touch with him. He didn't return his wechat, and I was worried all the time... " Ning Yuerong cried:

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

"According to our current understanding, Zhao Xiaoshan is likely to be missing."

"Missing? How could he be missing? Was he kidnapped or something? "

"We are also investigating his specific situation. Do you have the contact information of his parents?"

"No

"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 key to the house?"

"Yes, yes, I can take you."

"Well, we just want to make a note for you."

"That half an hour, we met at the east gate of Baiziwan community."

"Yes."

"Comrade police, what's your name?"

"My name is Han."

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

Ma Jingbo held his hands in his chest: "since Zhao Xiaoshan has the most conversations with Ning Yuerong, it proves that they are very close to each other and he knows the most. Let's go to Baiziwan community now and check Zhao Xiaoshan's parents' mobile phone number in the car."

Later, Han Bin and his party got into the car and prepared to continue to search Zhao Xiaoshan's parents' mobile phone numbers in the car. Li Hui called.

Zhao Xiaoshan's ID card has an address registered. Zeng Ping and others find Zhao Xiaoshan's parents according to that address.

Now I'm taking notes for Zhao Xiaoshan's parents.

This is equivalent to saving Han Bin and others. They just need to contact Ning Yuerong.

Baiziwan community.

There are four doors in Baiziwan community, three of which have been closed, only the east door is still open, so we need to measure the body temperature when we go in and out.

After arriving at the east gate of Baiziwan community, Han Bin takes out his mobile phone and dials Ning Yuerong's number.

Then, from a white Tesla car, down came a woman, wearing a gray mask, slim, dressed very fashionable, from the vaguely exposed eyebrows and eyes can see that she should be very beautiful.

Han Bin and others came down from the car: "Hello, is Ning Yuerong?"

"It's me. You're officer Han." The young woman came quickly. She was followed by a woman, a little older, who looked like Ning Yuerong.

Han Bin pointed to Ma Jingbo: "this is the captain of the city criminal investigation team."

"Team leader Ma, I just called Xiaoshan again, but my mobile phone still can't get through. Let's go to his home to have a look." Ning Yuerong urged.

The woman next to Ning Yuerong tugged at Ma Jingbo and said, "Captain Ma, I'm Ning Yuerong's mother. Can you have a look at your ID?"

Ma Jingbo showed his police certificate.

"Ah, it's actually a comrade of the municipal criminal investigation team. What's Zhao Xiaoshan doing? Do you want to find him?" Women are wonderful.

Ma Jingbo looked at the other side: "how to call it?"

"My name is Chen Xia. I work in the Municipal Women's Federation."

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

On hearing this, Ning Yuerong immediately worried: "what's the case? What's the danger of Xiaoshan? Captain Ma, please tell me quickly. What's the matter?"Han Bin advised: "Miss Ning, don't be too excited. It's only the investigation stage now. Maybe it's just a false alarm."

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