At one o'clock in the morning, the large office was brightly lit, and from time to time, police officers looked up from the computer, put some eye drops into their eyes, and then continued to work on the screen.
It was drizzling outside.
There was footsteps in the corridor, and Lin Qiupu greeted him. Two policemen rushed back from the outside. They were soaked. They said: "Several flour mills nearby have been checked, and there are no suspicious persons."
"Got it. Go and dry your body and take a break!"
"No, is there anything we can help?"
"Then watch the monitoring!"
The two policemen agreed to join the surveillance investigation. Although they were exhausted, everyone was full of energy.
Lin Qiupu was considering whether to expand the scope of the search. He asked Chen Shi’s opinion. Chen Shi said: “I don’t think it is necessary. It has been found that the person was missing at 3 pm, and the mobile phone was delivered at 5 pm. In the traffic conditions every afternoon, the place where they closed their people would not be more than 20 kilometers away from the missing place."
Lin Dongxue raised objections, "What if the kidnapped person was still on the move when the mobile phone was delivered?"
Chen Shi pondered, "Yes, I didn't think about this... How do you think this life and death decision will be realized? Is it through remote-controlled bombs?"
Lin Qiupu said: "The probability is like this. On this Nokia, the 1 and 2 buttons are set as fast dials, and the two target numbers are unowned mobile phones handled by a debit card. They may each control a bomb."
"Can you track the signal without making a call?" Chen Shi asked.
"It can be tracked by mobile phone PIN code." Lin Qiupu said, but his tone was not too high. "Actually, I have tried it. Those two mobile phones have not been turned on at all. They may not turn on until the deadline."
"Too cunning!" Lin Dongxue said, "If it is really a bomb, it will definitely be placed in a secluded place, right?"
"No, no, don't think of them too kindly, they won't avoid hurting civilians."
"How about tracing explosives?" Lin Dongxue said.
"Too slow, too late." Lin Qiupu shook his head, he had already rejected this idea.
Chen Shi said: "You may not be able to find it if you check it. A bomb that can kill does not require much power. It can be made with some daily necessities. Zhou Xiao should have this knowledge."
"How do you know!?" Lin Qiupu asked, "Zhou Xiao is a serial killer and Ling Shuang is a psychologist. How do you know they have this skill?"
"Intuition." Chen Shi shrugged, "I'll go out and make a call."
Chen Shi called KK and Sun Zhen and asked them to help find them. A little more manpower is also a lot of hope. Finding someone is really hard to trick. It is nothing more than a lot of energy input, which is a death stumbling.
It was four o'clock in the morning. Some policemen were so sleepy that they used cigarettes and coffee to beat up their spirits. Others lay on their seats and slept for a while. Lin Qiupu stared at the screen with red eyes. He was watching the surveillance around the Public Security Bureau. The suspect has been close to this place at least twice when he sent the'diagnosis certificate' for the second time and the mobile phone for the second time.
A suspicious person was indeed photographed in the surveillance. The person wrapped himself up so tightly that he could not even distinguish between men and women. Lin Qiupu chose the clearest picture and printed it out.
"Hey!" Someone sighed with a lazy waist.
"Don't sigh!!!" Lin Qiupu reprimanded loudly, "You know how depressing a sigh can make others feel, so please be more positive!"
"Okay... OK, Captain!"
"Where is Chen Shi?"
"He went to Captain Peng."
Chen Shi is being lazy. He was almost crazy from watching the surveillance that day. Go to Peng Sijue for a cup of coffee and empty your head. At this time, the technical squadron members are off work, and only Peng Sijue is still facing the instrument and the test tube verification object. , The room was quiet, only the sound of rain outside the window and the hum of instruments.
The reagent is taking effect. While waiting, Peng Sijue came over to pour himself a cup of coffee, sat opposite Chen Shi, watched Chen Shi yawning, and said, "Aren't you a night owl in the past? When did your work and rest habits change?"
"No matter what cats can't stand such intensive use of their brains... How are you and Miss Gu?"
"Starting to inquire about personal matters again?"
"care about you."
"Thank you for your concern."
There were footsteps in the corridor, and I knew it was Lin Qiupu. He appeared at the door, glanced at Chen Shi who was holding a coffee cup, and said, "Captain Peng, I'm sorry, for preventing you from getting off work all night."
"It's okay. Do your best. I don't want an accident in Lao Zhang's family."
"Are there any results?"
"Wait a mininute!"
Lin Qiupu sat down opposite Chen Shi, and Chen Shi said, "Don't stare at me, I am not your subordinate, I am really tired today."
"When you need your inspiration, you don't contribute at all."
"How difficult it is to find someone, don't you realize it?"
"Deep experience!" Lin Qiupu remembered the past.
Peng Sijue turned around from the test bed and said, "Would you like to use criminal geography for analysis? The Physical Evidence Center has such experts."
"That's useless, the suspect was kidnapped purposefully, and the range inferred by big data can't be searched within 24 hours." Chen Shi said.
"I think we need more manpower. I will contact the SWAT team and nearby police and co-policemen to help." Lin Qiupu said.
Peng Sijue stared at the results of the analysis from the mass spectrometer on the computer, and said: "The particles brought back from the scene today are still flour and lime."
"The suspect's hiding place can touch these two things." Lin Qiupu thought.
"If this clue was left by them deliberately, it's like this abandoned car today." Chen Shi said.
"At the moment we have no clues at all, and there is no room to play this kind of psychological game. Any clues must be traced to the end. Proof or falsification is a kind of progress!"
"Flour, lime..." Chen Shi groaned, "Not only the flour mills have these two, but also small workshops, noodle restaurants, and warehouses. They need to use a car. There must be a parking space there, and it is not easy to be suspected."
"In fact, there are some salt, but this ingredient is too common." Peng Sijue said.
"Is it edible salt?"
"From the perspective of iodine content, it belongs to industrial salt."
"Many people who make non-staple food use industrial salt, because it is cheap, it may be a non-staple food workshop... By the way, if they hide here, will they pretend to be the staff there? Maybe someone at the scene of the crime witnessed the dress People in this type of workwear..." Chen Shi stood up and prepared to go out.
"Why are you going?" Lin Qiupu asked.
"Return to the car and go to bed. I'll go back to the scene tomorrow morning to find out... You guys should go to bed too, really treat yourself as an iron man!" Chen Shi said as he walked away.
Lin Qiupu glanced at his watch. It was five o'clock. It should be time for everyone to rest. There will be a tough battle tomorrow!
