Bai Song never expected that there would be such an unexpected gain.
At that time, almost everyone's attention was focused on the crime scene, and few people paid attention to the crowd around. But now think about it, there is always a possibility that there are problems among so many onlookers.
Bai Song even saw the figure of the farmer who was captured today in several key pictures sorted out by Zhao Xinqiao with just one glance!
This person was indeed at the scene at that time, and the person who followed Bai Song later should be him.
After calming down, Bai Song analyzed the situation carefully and pointed to the computer screen: "We caught the person you marked today."
"Who is he?" Zhao Xinqiao was a little confused: "You didn't tell me that you arrested any important person today."
"I don't know if he is an important person, but with this video, there is definitely something wrong with him." Bai Song continued to look at a few pictures: "How did you find out that there is something wrong with this person?"
"His gait and demeanor are not normal." Xinqiao pointed to several other photos and said, "Look at the corresponding video. This person is nervous."
"Nervous?" Bai Song looked at the video and nodded: "Indeed, he is. But if he is nervous, it means that he is not a key figure. He is just a small fry. I guess he doesn't know what to do with him as a breakthrough point."
"Well, take another look at this person." Zhao Xinqiao pointed at the second person, "This person has looked at the person you just mentioned several times, and he is wearing headphones."
Bai Song opened the second set of photos and watched the video carefully.
After all, mobile phone videos have limited clarity. If you only watch them once, it is impossible to tell the condition of each person. All these photos were cut out from the video and the key points were marked.
The horizontal field of view of the human eye is 188 degrees, but the field of view of concentrated attention is only 25 degrees. If you stare intently at one point, you can only observe one person in the entire video.
In other words, even though this video is only more than 20 minutes long, it can take a long time to analyze in detail. Zhao Xinqiao watched it many times without getting tired of it before he came up with these statistics.
After watching carefully for a few minutes, Bai Song realized that there was indeed something wrong with this person. He had "inadvertently" looked at the farmer twice, and he was wearing headphones and talking. Although one could not hear what he said, it was certain that he was not talking to the people around him.
The video is still not clear enough, and if you don't stare closely at this person, you won't gain anything.
Bai Song changed his perspective again to the farmer, but he couldn't see whether he was wearing headphones or not.
"Does it help you?" Zhao Xinqiao asked.
"Yes, and it's very big." Bai Song was very grateful. After watching the videos, he was very moved. He stood up and prepared to hug Zhao Xinqiao.
"Get out of the way, and go work on your case." Zhao Xinqiao pushed Bai Song away, then turned and went into the second bedroom. "Don't be too hasty about this matter. I won't think too much about it."
…
Bai Song watched Zhao Xinqiao go to the next room, and he stared at the computer and laughed foolishly for half a minute.
Do you want to call Wang Liang again to show your love?
I heard that Ma Zhiyuan's sister and Ma Zhiyuan have different personalities. Maybe Ma Zhiyuan dotes on his sister. His sister is a good student, but her personality is still that of a little girl. Her relationship almost makes Wang Liang exhausted.
Forget it, just be a human being.
Bai Song thought about it and directly sent the photo of the second person to Captain Qin’s mobile phone, and then called Captain Qin to tell him about the situation.
"Is this person the farmers' superior?" asked Captain Qin.
"The farmer didn't say a word from beginning to end, but he spoke a few times, and it seemed like he was directing the farmer. Every time he finished speaking, the farmer would look at him a few more times." Bai Song explained: "The video is too large to be sent from the email. I will put it on the network disk later."
"Okay, send it to us so we can study it." Captain Qin said, "This discovery is very important. Maybe it is the key to the case. Who discovered it?"
"Um, my girlfriend." Bai Song paused for a few seconds and decided to tell the truth.
"Your girlfriend?" Captain Qin really didn't expect this time: "Okay, you are quite good... I see, uh, keep it a secret."
The style of the painting changed a bit. Bai Song coughed twice and said, "Don't worry... Um, Captain Qin, I have something else to say."
Captain Qin might have been choked by what Bai Song had just said. He hummed lightly, wanting to hear what Bai Song was going to say.
"It's like this, the farmer we caught today had a very clean phone, and there were no earphones. I suspect that they didn't use our 2G to 4G network communication, but adopted their own radio waves to communicate." Bai Song said: "It just suddenly occurred to me that when I was in Tianbei District, I met Baldy and others, and I happened to meet them going to the factory at night. This is not a coincidence.
It is very likely that these people installed these devices. Although they can indeed control black radio stations and other equipment, they can also be used for their own communications. As long as we don't know about this in advance, it will hardly be discovered.
So, Tianbei District itself had some similar equipment, but after I went to the Economic Investigation Corps, they got hold of my whereabouts and temporarily installed one there.
This kind of equipment must still exist in Jiuhe District. I think we can take technical measures to counter it. Maybe we can discover some illegal channels and find some necessary things in reverse.
I am thinking that if we find it, we can monitor it first and not rush to alert the enemy."
"Okay, hurry up and send the video over." Captain Qin became serious after hearing Bai Song's words: "You should have a good rest at home. I know about this matter."
After hanging up the phone, Bai Song did some work and uploaded the video and some photos organized by Zhao Xinqiao to a network disk. Then he gave the account and password to Captain Qin and leaned back on the bed.
After thinking for a long time, Bai Song felt a little sleepless, so he took out the telescope from the balcony and started looking around.
Is there someone in the community watching him vaguely?
Bai Song suddenly became nervous. Someone was watching him? And they knew where he lived?
I secretly pointed the telescope at that person and slowly focused...
Uh? Isn't this Lao Sun from the second team?
Bai Song looked carefully and it was true!
Oh my god…
Bai Song then looked around with the telescope and found another familiar figure.
well……
This is the group I love so much...
