Zeng Ping left the scene.

The other team members went to investigate.

Han Bin stood around the scene, watching the crowds who were looking at him and the scene.

The suspect took so much effort to put the victim in this way, it is very likely to show off as his own trophy.

In other words, he is likely to return to the scene again to appreciate his trophy.

At this time, a man came over, wearing a dark blue down jacket and wearing gold glasses.

"Excuse me, are you the police comrade in charge of this case?"

"I am, what's the matter?" Han Bin looked at the other side.

"I'm Niu Ben's father, one of the three kids who discovered the snowman."

"What's your name?"

"Niu Genshan."

"Mr. Niu, I was just looking for you." Han Bin stretched out his hand and shook hands with the other party.

"The child was terrified. I just sent him home." The man said helplessly.

"This kind of child is indeed very troublesome. It is precisely because of this that we did not look for it in the first time."

"Thank you for understanding, comrade, what's the situation with that case?" Niu Genshan asked.

"Still under investigation."

"Then I won't ask more. I didn't mean anything else when I came here. First, I was not at ease, so I came and took a look. Second, if the police really want to ask about the situation, you should look for me instead of going to school to find a child. The child is really frightened, but can't be tossed anymore." Niu Genshan sighed.

"Don't worry about going to school, let the children rest for two more days." Han Bin said with concern.

Niu Genshan shook his head: "I plan to send him to school tomorrow. There are many children in the school, but he is not afraid. There are few people at home and it is easy to think."

This is a private matter of others, and Han Bin is not asking too much, and the conversation changed: "Did the child tell you about the scene?"

"I am also afraid of the child being injured, so I asked what happened." Niu Genshan took out a cigarette and handed it to Han Bin who was aside:

"My child went to school with two classmates. I saw this snowman on the road. The three little boys were all naughty ages. So they started to beat the snowman, only to find that there was a person hidden inside, and he lost an eyeball. Frightened my child."

Han Bin waved his hand and signaled that smoking is not allowed here: "At that time, did they see suspicious people and vehicles?"

"The child was so scared that he lost his soul, how could he notice so much."

"If possible, I still hope to help the police understand more about the situation and solve the case earlier, which is also a good thing for the children."

"No problem, we will think of a way to slowly talk from the child, but I still said that, I hope the police will not directly contact the child, the child is timid, crying when I say it, I feel uncomfortable watching it. ."

"Don't worry, the police will not directly contact the child. Even if they want to inquire, they will get the consent of the guardian."

"Thank you so much, then, with your words, I will rest assured." Niu Genshan said a few more polite words and left the scene.

Han Bin sighed, also a little helpless.

It stands to reason that he should ask the three children, but some things need to be handled flexibly.

Not far away, Li Hui and Sun Xiaopeng came over.

Li Hui rubbed his ears: "I'm freezing to death. I would buy earmuffs if I knew it."

"Are there any clues?"

"It's all about watching the excitement, don't ask them, they asked me the other way around." Li Hui huffed in his mouth and hurriedly put it on his ear.

"Where is the informant?"

"There is no around, probably left."

Although the bodies of the three children were found in the first time, they were too young and frightened, so they could not ask questions.

Then we can only start with the informant.

Although it is not first-hand news, the accuracy should be higher.

For the three frightened children, even if they said something, the evidence may not be credible.

Animals like humans like to replenish some non-existent things in their brains unconsciously.

"Li Hui, you are responsible for finding the informant and asking him to come to the branch to take notes."

"understood."

Not long after, Du Qi and the three also came over.

After this time of getting along, Du Qi has gradually integrated into the second group, and the relationship with the group members has become more tacit.

"How is the surveillance investigation?" Han Bin asked.

Du Qi stomped his feet, shaking the snow on the back of his feet: "The surrounding area is all newly developed. It was only a few years away. The location was a bit remote. There were not many shops around, so I could not directly photograph the case Surveillance of the spot."

"Are there any suspicious vehicles?"

Du Qi pointed to a few shops in the distance: "Checked a few shops, because the neighborhood is newly planned. Not only is the road wide, but the front of the shop is also wide. The video of private shops can't be shot on the road. I can only go back and check Skynet."

Han Bin glanced at his watch. It was already four o'clock in the afternoon: "In this way, I will reschedule the task."

"Li Hui contacted the reporter to make a record."

"Tian Li is investigating the source of the corpse during the surveillance of the police system."

"Du Qi took people to the traffic police monitoring center to check the suspect's transportation."

"Yes."

...

After returning to the branch.

Han Bin wrote several investigation directions on the whiteboard, including corpse source, first scene, transportation, genetic material, footprints, and snowman case.

After investigating these clues clearly, the general situation of the case can be found out.

Soon, the technical team sent high-definition photos of the scene, and Han Bin glanced through it. His footprints were messy and messy.

What Han Bin can do now is to write down these footprints so that he has a general impression in his mind.

When the suspect is found, the suspect's footprint can be compared with these footprints.

Or, if this case and the snowman case are the same murderer, you can compare the footprints of the two scenes. The two cases are separated by a year, and the same person's footprints appear at the two crime scenes, then this person is very Suspicious.

It may even be the murderer.

Han Bin arranged for everyone else out, at this time, he was the only person in the office.

"Da da da..." A sound of footsteps sounded. Although the sound was not loud, Han Bin still heard the identity of the person coming.

Tian Li entered the house and put a document on Han Bin's desk: "Group leader, I checked the missing person recently and found a girl in a situation similar to the deceased."

Han Bin packed up the photos: "When did you report the case?"

"This morning, the police called the police station on Tong'an Road."

Han Bin checked the information. The missing person was Zhang Yiyi, who was 18 years old this year, and was from this city. The time of missing was yesterday morning.

"The situation is more consistent. Contact the informant and ask him to come over."

"Yes."

Before long, Li Hui and Zhao Ming also returned to the office.

Han Bin opened the door and said, "Have you contacted the informant?"

"I got in touch. He said he couldn't make it through today, and he won't be able to come over and take notes tomorrow." Li Hui shrugged.

Zhao Ming spread his hands on the sidelines: "Don't worry about how big a case is, it's none of your own business, people just don't worry."

"Remember to remind you tomorrow."

"I see." Li Hui yawned and said subconsciously: "Binzi, there is such a big case, how can we never see the Zeng team show up."

"Team Zeng went to the scene and left." Han Bin said.

"It shouldn't be, it is considered a big case."

"Team Zeng said that he had heard of a snowman case before, which was somewhat similar to this case. He went to inquire about the snowman case."

"The snowman case is quite vivid." Zhao Ming said.

"Hey, listening to you say this, I really want to have a little impression." Li Hui showed a thoughtful look.

Han Bin didn't urge him either, turning his head and looking out the window, most of the snowball placed outside the window had already melted.

...

Half an hour later, Tian Li returned to the office with a man behind him.

The man appeared to be in his forties. He was wearing a black padded jacket with some oil stains on the cuffs, an anxious look on his face, and a layer of beard stubble around his mouth.

"Team leader, this is the informant of Zhang Yiyi's disappearance." After Tian Li finished the introduction, she pointed at Han Bin: "This is our team leader Han."

The man strode over and hurriedly held Han Bin's hand: "Group leader Han, have you heard about my daughter?"

Because it is still uncertain that Zhang Yiyi is the deceased, in order to avoid the man being too anxious, Tian Li did not tell him that the deceased was probably her daughter.

"What do you call it?" Han Bin made a please gesture and motioned to the other party to sit down.

"My name is Zhang Dagang and I am Zhang Yiyi's father. My daughter has been missing for more than a day. Please help me find her."

"When did your daughter disappear?"

"The home I left yesterday morning can no longer be contacted. It has been more than 30 hours now." Zhang Dagang sighed.

"Does your daughter go to school or work?"

"Study, she goes to Kotoshima Technical College."

"Does Qindao Technical College seem to be on holiday?" Zhao Ming interrupted.

"Yes, I went out last morning. I went to the night shift at night. She hadn't come home yet. I didn't take it as a matter of time. But when I came back this morning and found that there was still no one at home, I was in a hurry and gave it to her. Calling, the cell phone is no longer in the service area." Zhang Dagang showed a worried look.

"Mr. Zhang, what do you do?" Han Bin asked. ,

"I do maintenance on the railway. The train runs during the day. In order not to affect the operation, we usually do maintenance at night."

"What time did you leave home last night?"

"Oh, it's about seven o'clock. When I left, I sent a message to tell her to go home early and close the doors and windows. She gave me back to know."

"Have you contacted since then?"

"I was thinking, I called her at 8 or 9 o'clock in the evening, but I forgot when I was busy." When it came to this, Zhang Dagang expressed regret: "Blame me, if I made a call, maybe Yiyi would just Won't be missing anymore."

"Are there any characteristics in your daughter?"

"What, what do you mean?" Zhang Dagang was a little flustered: "Didn't you say that there is a clue about my daughter? Why did you ask me about my characteristics?"

"We are not sure if it is your daughter."

Zhang Da just stood up with a trembling voice, "What's wrong with my daughter, is it hurt?"
