"Did you see it alone that day?" Shao Lao asked.

S Saidon nodded, and said with some credit: "It's just me, it's a coincidence, if I hadn't seen that kid, maybe I'd never know who he killed. You talk about how terrible this is. , Fortunately, he has been exposed now, if he commits another case, he will be shot directly, am I right?"

S Saidong looked at Police Li.

Police Li shook his head: "It's not like that..."

S Saidong said impatiently: "You guys are just grinding, knowing that he is a murderer, but it is because of lack of evidence that someone cannot be arrested. But I recently heard from people in the village that there is a righteous boss. Hire a killer to kill Wang Liguo and everyone else."

"It's your police officers who are chasing and chirping, so others are in a hurry." Susseidon was firm and firm.

"There is not enough evidence to prove that Wang Liguo killed someone. Shouldn't we be more careful about the matter of one's life?" Shao Lao also stood up at the moment, he turned his head and said to Police Li: "So, go Take a look at Wang Liguo's family, maybe you can get some new clues from Wang Liguo's mouth."

Police Li nodded and led the crowd to Wang Liguo's house.

I saw S Saidong shouting from behind: "Police officer, this is really not me raising the bar. Everyone in the village knows who Wang Liguo is. He is like his father. If you don't believe it, just go out and ask. Ask a question. I could see clearly at the time that he was holding the big arm of the child with his hand. Why don't you say, are the two of them taking a mandarin duck bath?"

Until a few people walked to the gate of Wang Liguo's house, everyone could still hear S Saidong's shouting behind him.

The big iron door of Wang Liguo's house was tightly closed, and no light could be seen from the cracks in the door.

Police Li pushed it, but the door was not locked, and was directly pushed open by Police Li. Everyone filed in and entered the courtyard. At this moment, the sky was gradually dimming, and looking around with the last sunlight, everyone found that the walls of the house were covered with words written in red paint, such as "debt repayment" and "death".

Under the glow of the red sunset, the words written in red paint were illuminated red and red, and the dim and quiet environment made people feel uncomfortable from the bottom of their hearts.

The lights were not turned on in the dimly lit room, and Police Li called several times in the yard, but there was no response.

A few people tried to push the door and found a total of three rooms in the yard, but found that each door was unlocked. Standing at the door and looking at it, several rooms are empty, broken and worthless furniture, broken plates, glass bottles, etc., piled up garbage that has not been cleaned up for a long time, a piece of wood randomly built Wooden bed.

No wonder Wang Liguo's family didn't even lock the door, even the top thief couldn't find anything valuable from his house. Wang Chenglong is a 20-year old gambler, and it is not bad that he has not sold all his houses.

But the question is, what did Wang Liguo's family do? It is normal to say that Wang Liguo's parents fool around every day, but Wang Liguo was dismissed by the school, and it is impossible for him to continue living in the school dormitory. If Wang Liguo didn't follow Wang Chenglong home, where did he go?

"Don't move." Jiang He said, "You stand outside, I'll go in and take a look. This will preserve the traces of the scene to the greatest extent possible."

Jiang He did not enter in a hurry, but turned on the flashlight with his mobile phone, and observed the clues in the three rooms, trying to find out what clues to come. He turned on the lights in several rooms, the filaments flickered, and finally came on. Jiang He paced the room alone. Five minutes later, Jiang He had an answer.

"It didn't take long for him to go." Jiang He said when everyone was at a loss.

Everyone looked at Jiang He.

Jiang He eloquently said: "The windows of all the rooms were almost broken, the room was covered with dust, and the wooden bed in the main room leaning against the window~ there was almost no dust on it, which means that someone lay here not long ago. . If you look closely at the dust on the windowsill, you will see traces of the arrangement of the dust, and the wind is blowing the dust into the house.”

"From these arrangements, in just a few hours, the wind will blow this dust onto the bed by the window, leaving a thin layer of dust on the bed. Judging from the footprints on the ground , This person is about 1.67 meters tall. The Wang Liguo I saw was about 1.7 meters tall."

Police Li said, "But Wang Chenglong is so tall."

"Then it's impossible to judge from the height." Jiang He said, "But I noticed that there was a kind of spicy sticky food in the pile of garbage in the house, and the red oil left in it was still dripping on the ground. The red oil on it has not completely solidified. There is no dust on the bottle of green tea next to it, which is also newly left."

Jiang He looked at Lao Shao: "I am 80% sure that whether it is Wang Liguo or Wang Chenglong, they will leave at about noon today."

Shao Lao shook his head and said, "It's either Wang Chenglong or Wang Liguo. Wang Chenglong will spend any money on gambling, even if it's fifty cents, he won't use it to buy green tea and spicy sticks, and, Adults generally do not choose to eat spicy strips."

"But I don't think he will come back." Shao Lao said.

"Why?" Jiang He asked.

Shao Lao replied: "Because he did not lock the door after he left, not locking the door means that he does not feel that this is his home in his heart, so he does not have a sense of ownership. However, there is no surveillance in the village. It's a mystery where it is."

"These children are really more worry-free than each other." Shao Lao said helplessly.

"If it's a child of peace of mind, I'm afraid he won't go to school bullying." Xu Yiman shrugged and said, "But is this a coincidence? left."

Shao Lao looked at the yellow light shot from the broken window, shining on the red paint, combining into a faint orange.

"No." Shao Lao said: "Zhuang Qinyun broke out because of depression, and Wang Liguo probably wanted to leave a long time ago."

Just as he was talking, Jiang He felt that someone was pulling his arm. He turned around and saw that it was Guan Deng. Not knowing when, the member of the task force with a low sense of presence had already taken out his laptop from his backpack and held it in his hand.

Jiang He went to see it, this is a video. And this video is obviously slow, and the screen will only move for two seconds. But even so, Jiang He recognized the source of this video at a glance. This video is the one where someone left a "killing" note, the one at the gate of the Public Security Bureau.

"Is there a clue to that 'killing' note?" Jiang He asked.

Guan Deng nodded vigorously.

"Look, maybe we can find the suspect." Shao Lao said.

Several people watched this video quietly. The duration of this video was five minutes in total, but because it was played slowly, there was not much content in the picture.

In the video, it is the gate of the Public Security Bureau. There are endless pedestrians on the road. In the video, pedestrians walk past one by one. At three minutes and two seconds, the note appeared on the ground. However, the surveillance of the Public Security Bureau could not reveal who threw the note, and the person who threw the note was not within the scope of surveillance.

And this is the troublesome point. There are no other surveillance cameras around, and the only surveillance camera does not reveal who the person who lost the note was. Otherwise, the police would not have to be so clueless. The whole video is over like this, and everyone still doesn't see anything.

This is not in line with Guan Deng's character. If he is not 100% sure, Guan Deng, who suffers from severe social phobia, will not take the initiative to attract the attention of others, especially Guan Deng chose to pull La Jianghe's arm. Although Guan Deng still did not speak, he also took the first step of his own.

"What's the difference between this and what we saw before?" Yuan Jun scratched his head and said, "Except that you deleted a lot of useless videos and slowed down the speed of this video."

The rest of the people didn't see any difference.

"There's a big difference." Jiang He took the lead and said, "Guan Deng, how did you find out?"

Guan Deng held the computer with one hand, and typed quickly on the keyboard with the other: "I chose the day before the note appeared as the length of the video, and designed a program to recognize faces. This program is very rough, just At the beginning, I would capture images that were similar to but not human faces, so I gradually modified the parameters, and the program became more and more accurate.”

"Until just now, my program ran the video again. When you were looking at the house, I checked the results." Guan Deng continued: "The program intercepted eight faces, but no matter how I look at it, there are only seven people. .I looked at the screenshots, and there was one face that was blurry, but it was the key to solving the case."

"Genius!" Jiang He praised, "Genius!"

"You two are chatting so much, what did you see?" Xu Yiman asked.

"Keep playing the video and stop at that position," Jiang He said.

Guan Deng nodded and fixed the video at the key clues.

"There is no note on the ground, which means that it is the moment before the note appears." Xu Yiman said: "But we have watched the video several times before, and we can see that it is not thrown from the hands of these passing pedestrians. come out, or fall out."

"No." Jiang He shook his head: "The video has already told us about the person who threw the note."

"Who?" Xu Yiman asked.

Jiang He stretched out his finger and pointed to the corner of the video. It was a metal cylinder that appeared on the scene. In a short time, even less than half a second, a vague shadow was reflected on the cylinder. Grabs a note that is about to be thrown away.
