Detective from The Future

"Han Bin, let's talk about it first, but Ding Detachment often praises you in front of me."

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

Privately, Ma Jingbo would call the opposing team leader, and in front of outsiders he would call the deputy team leader.

It is still very particular about using different titles at different times.

This is not the first time Han Bin and Ma Jingbo have seen each other. During the 101 project, the two had also worked together, and Han Bin was no stranger to him.

"I think it is possible to locate a suspicious mobile phone number. It would be best if the current location can be located; if the mobile phone number is not in the service area, the location of the last call with the mobile phone number can be located. The suspect must have been nearby, maybe. What evidence is left."

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

Ma Jingbo nodded: "Wang Xiao, call the technical team of the Municipal Bureau soon and ask them to contact someone from the communications company to locate the suspicious cell phone number."

"Yes."

"Does anyone else have any ideas?"

"cough……"

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 is missing, the family can also provide some clues before the disappearance."

"Li Hui is right, right."

Ma Jingbo added: "Not only the family of Zhao Xiaoshan, but also the families of the first two victims, Ren Jianhua and Cao Da, should also be notified and asked to come to the branch to make transcripts, and then cross-check their transcripts to see if they can find common clues. ."

"The remains of two deceased were found in the dog's stomach. One of the deceased was confirmed to be the second missing person, Cao Da, after DNA comparison, but the identity of the other deceased is still uncertain. I guess the other deceased is very It may be the first missing person, Ren Jianhua, so when you notify Ren Jianhua, it’s best to let your immediate family members come."

"The current situation is like this. I will arrange the task." Ma Jingbo said this and ticked on the notebook: "Captain Zeng will be responsible for locating the phone and tracking the suspect."

"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 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 replied.

The city criminal investigation team has law enforcement powers throughout Qindao, which is much more convenient than the Yuhua branch criminal investigation team.

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

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

Zeng Ping nodded and led Wang Xiao, Li Hui and others out of the meeting room.

After watching Zeng Ping's person leave, Han Bin suggested: "Captain Ma, since Zhao Xiaoshan may be still alive, I suggest starting with him to investigate, maybe we can find some valuable clues."

"I think so too. The other two cases are far away. Zhao Xiaoshan only lost contact 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 communications company to print out Zhao Xiaoshan's communication records."

Ma Jingbo waved his hand: "I should contact the technical team of the Municipal Bureau. They have always cooperated with the communications company, and the procedures are simpler."

Han Bin was also happy and relaxed: "The horse team, what are we doing now?"

Ma Jingbo glanced at Han Bin, Zhao Ming, and Tian Li: "If all 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 retaliatory killings, like the first victims of the Snowman case? These three young men are replacements for someone. Product."

Ma Jingbo took the stubborn words: "I have seen the file of the Snowman case. The murderer in the Snowman case is not a standard serial killer. According to your guess, the murderer in the 131 case is more mature than the murderer in 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 Snowman case is not caught, he will continue to kill, and it is likely that he will continue to look for a substitute for his wife, and he will become the murderer of the 131 case and become a standard serial killer.

Once there is no element of revenge, there is no direct contact between the murderer and the victim. The murderer may have looked at the victim on the street and will treat the victim as the next substitute.

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

The mask was a little bit uncomfortable, and Han Bin shrugged the mask: "Zhao Ming's guess is a certain possibility, but now we know too little about the nature of the case."

Taking advantage of the effort of discussing the case, the four of them each made a bowl of instant noodles, each with a ham, even 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 city criminal investigation team is indeed higher than that of the technical team of the branch. As soon as the four of them finished the instant noodles, Zhao Xiaoshan's communication records were sent to Ma Jingbo's WeChat.

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

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

"Hey." A woman's voice came from the phone, which sounded not too old.

Han Bin didn't know the identity of the other party either, and tentatively asked, "Is Zhao Xiaoshan there?"

"Who are you?" the woman asked back.

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

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

"What is your name?"

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

"I'm from the Criminal Investigation Team of Yuhua Branch, and I want to get some information about Zhao Xiaoshan."

"What's wrong with Xiaoshan, I'm also looking for him, what happened to him?" Ning Yuerong said anxiously.

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

"Yesterday morning, we were still on the phone. Later, his cell phone went down and I couldn't get in touch. He didn't respond even after sending WeChat. I was always worried..." Ning Yuerong cried:

"Comrade police, what happened to Xiaoshan?"

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

"Missing? How could he be missing, was he kidnapped, or what."

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

"No."

"Do you know where he lives?"

"Xiaoshan did not live with his parents. He lived by himself 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 there."

"Alright, we are just trying to make a note for you."

"In that half an hour, let's meet at the east gate of Baiziwan Community."

"can."

"Comrade police, what do you call?"

"My last name is Han."

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

Ma Jingbo put his hands on his chest: "Since Zhao Xiaoshan has the most calls with this Ning Yuerong, it proves that the two people are very close and he knows the most. Let's rush to the Baiziwan community now, and we can check Zhao Xiaoshan in the car Parent’s mobile phone number."

Afterwards, Han Bin and his group of four got into the car, and when they were about to look up the phone numbers of Zhao Xiaoshan's parents in the car, Li Hui called.

Zhao Xiaoshan’s ID card has a residential address registration. Zeng Pingping searched according to that address and found Zhao Xiaoshan’s parents.

Now I'm making a transcript for Zhao Xiaoshan's parents.

This is tantamount to saving Han Bin and others. They only need to contact Ning Yuerong.

Baiziwan District.

There are a total of four doors in Baiziwan District, three of which are closed, and only the east door is left open. Body 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.

Later, from a white Tesla car, a woman walked down, wearing a gray mask, slender figure and very fashionable dress. From the faintly exposed eyebrows, it can be seen that she should look pretty.

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

"It's me, you are Officer Han." The young woman walked over quickly. Behind her was a woman, a little older, with a look similar to Ning Yuerong between her eyes.

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

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

The woman next to her grabbed Ning Yuerong and said to Ma Jingbo on the side: "Captain Ma, I'm Ning Yuerong's mother, can I see your documents?"

Ma Jingbo showed the police officer ID.

"Hey, it's a comrade from the city criminal investigation team. What did Zhao Xiaoshan commit? You want to find him?" the woman curiously asked.

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

"My name is Chen Xia and 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."

Upon hearing this, Ning Yuerong suddenly became anxious: "What case, what is the danger in Xiaoshan, Captain Ma, please tell me what is going on?"

Han Bin persuaded: "Miss Ning, don't be too excited. It's still in the investigation stage, maybe it's just a false alarm."

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