Han Bin turned on the headset: "Team Zheng, it's not a matter for us to keep following like this." ”

"Do you have any good ideas?" Zheng Kaixuan said.

"I suggest that Sheriff Sun call up the surveillance around the square, and if the old lady is really picking up garbage, she should go there often. Han Bin said.

"Well, that's a good idea. Zheng Kaixuan responded and instructed Zeng Ping on the side: "Lao Zeng, contact Sheriff Sun and ask him to call up the surrounding surveillance and verify the identity of the old lady." ”

"Yes. ”

The five of them followed all the way, and the old lady found nothing abnormal.

Han Bin and the others did not see anyone else following.

Forty minutes later.

"Jingle Bell ......"

Zeng Ping's mobile phone rang, and it was Sun Hao calling.

"Lao Zeng, I checked the surveillance near the square, and the old lady would pick up garbage nearby almost every night, and found nothing unusual. Sun Hao said.

"I see, you've worked hard. ”

"It should. After Sun Hao finished speaking, he hung up the phone.

"What do you say?" said Zheng Kaixuan.

Sun Hao checked the surveillance, and the old lady often picked up garbage in that area, and it was unlikely that she was a suspect. Zeng Ping said.

"Team Zheng, the old lady has walked into the path, and it is estimated that it is not far from her house. Li Hui's voice came from the headset. ”

"Team Zheng closed the Internet café and asked the old lady to take the money home, but it would be difficult to do. Zeng Ping said.

Zheng Kaixuan hesitated for a moment: "Close the net." ”

......

Not far ahead of the car.

Han Bin rode an electric car and caught up with the old lady directly, and after passing her a few meters, he crossed the electric car and stopped in front.

"What are you doing in front of me, such a wide road?" the old lady asked.

Li Hui and Tian Li also chased after them, sandwiching the old lady in the middle.

"Who are you?" said the old lady, a little nervous, as she put the cart in the back.

"Auntie, don't be afraid, we are police. Li Hui said.

"Police, what's the matter with you?"

"Auntie, go to the square to pick up garbage tonight, do you want to go yourself, or did someone tell you to go?" Li Hui said.

"You still need to teach you to pick up garbage, if you want to learn, follow me to pick up for a few days. The old lady said.

Li Hui was speechless, he was a good policeman, why did he run to pick up garbage.

"Old lady, we are investigating a blackmail case, and the 50,000 yuan you took is the extortion money. Tian Li said.

"Eh, what 50,000 yuan, I don't know what you say?" the old lady hurriedly denied.

"You didn't take 50,000 yuan, what are you doing so fast?" Li Hui said.

"I don't want to exercise. The old lady quibbled.

"Excuse me, come with us to the police station to assist in the investigation. Tian Li said.

"Why, I'm not going. The old lady shouted.

"Auntie, I know you may be innocent, but that money is extortion, whoever takes it has to go back with us to make a record. Tian Li said.

Li Hui and Tian Li coaxed and deceived each other, and finally persuaded the old lady and took her back to the substation.

......

Kotoshima Branch.

Li Hui and Tian Li were responsible for making notes for the old lady.

Zheng Kaixuan made a pot of tea and sat at the table with a serious face.

"You two come here, let's have a meeting. ”

Zeng Ping and Han Bin walked over and sat next to Zheng Kaixuan.

"Has Sun Hao withdrawn over there?" Zheng Kaixuan said.

Sun Hao withdrew, leaving two policemen to guard in the car. Zeng Ping said.

"Where's the Anyang Apartment?"

"Zhao Ming called me, there was no abnormality over there, and I asked him to continue squatting. Zeng Ping said.

"Why didn't this blackmailer show up, and what he was trying to do, I was a little confused. Zheng Kaixuan said.

"Could it be that he found out about us, so he didn't dare to show up. Han Bin said.

"No, we've been careful today. Zeng Ping said.

Han Bin recalled for a moment: "I really didn't see any suspicious people. ”

"Tomorrow, the surveillance near the People's Square will be re-checked to see if there are any suspicious people between 6 p.m. and 12 p.m. Zheng Kaixuan said.

"Yes. ”

At this moment, Li Hui and Tian Li walked in.

"Is the money coming back?" asked Zheng Kaixuan.

"It's all here. Li Hui put the black plastic bag on the table.

"This old lady has no spirit to collect money at all. Zeng Ping shook his head.

"Do you think this old lady is suspicious?" Zheng Kaixuan said.

"The confession has been recorded, the old lady's name is Li Yuanfang, a native of Qindao, who often picks up garbage near People's Square, and has no intersection with the victim, so the suspicion can basically be ruled out. Li Hui said.

"Team Zheng, the old lady is also quite pitiful, she followed us to toss all night, or give her a hundred yuan. "Tian Li has a good heart.

"I'll pay for this hundred dollars. Zheng Kaixuan said.

"The old lady is fine, it means that the clue is broken again. Zeng Ping sighed.

"Team Zheng, I want to interrogate Yu Hefeng again to see if he can provide any clues. ”

"It can be used as a breakthrough. Zheng Kaixuan said.

"Li Hui, Tian Li, you went to investigate near Anyang Apartment today, do you have any clues?"

"We have called up the surrounding surveillance, and no suspicious person has been found so far. Li Hui said.

"Tomorrow we will continue to investigate. Zheng Kaixuan said.

"Yes. ”

"Team Zheng, I want to see the blackmail photos. Han Bin said.

"I've seen the photos, they're all relatively private, it's not convenient for you to be a big man, if you have any questions, you can ask me." Tian Li said.

"Okay, it's all this time, don't come to the difference between men and women, let Han Bin see it. Zheng Kaixuan waved his hand, the clues were all broken, and new clues must be found as soon as possible.

This is just like a doctor and a patient, who has already been seriously ill, and it is not certain whether it can be cured or not, so it is natural to find the most suitable doctor.

Otherwise, the suspect will post the photo online, causing more harm to the victim.

"Alright, it's not too early, I'll be here tonight, and we'll all go back to sleep. ”

Zheng Kaixuan said, and took out a hundred yuan: "Give the money to the old lady and ask her to take a taxi back." ”

"Yes. ”

......

The next morning.

Han Bin came to the office with two dark circles under his eyes.

When I got home last night, it was already past two o'clock, and it was three o'clock when I cleaned up.

I didn't sleep for a few hours, and I had to get up and go to work.

Li Hui and Han Bin both got up late, and the two didn't eat, so they came directly to the office.

Except for Zhao Ming, everyone else is there.

Tian Li took two breakfasts and put them in front of Han Bin and Li Hui: "Eat, Team Zeng bought it for you." ”

"Team Zeng, you are really a god, how do you know that we haven't eaten. Li Hui swallowed a xiaolongbao in one gulp, and said vaguely.

Zeng Ping lit a cigarette and took a puff: "I also came from your time, hurry up and eat." ”

After eating, everyone threw themselves into the intense work again.

According to the task arranged by Zheng Kaixuan last night, they investigated separately.

Relatively speaking, Han Bin's job is relatively easy, staying in the office to study photos.

These photos can clearly see the appearance of the victim, and if it is spread on the Internet, the consequences are unimaginable.

Han Bin carefully observed each photo, and then, compared it with the video on the computer, after some research, he really found new clues.
