"Detachment Zhuang, you Inspector Bai have something in your hands. The expression of the Liu detachment of the Xijing Branch was a little solemn: "Just now, the Wang team told me that this case is really strange. ”

"If it was simple, the headquarters wouldn't have arranged for us to come over. The Zhuang detachment has a sense of "Bai Song is my person", and it is slightly cold: "After all, the leaders of the corps are well-informed. ”

"That's that, that's. Detachment Liu took out a cigarette and handed one to Detachment Zhuang: "I hope there will be results sooner." ”

...

In just half an hour, the person in charge of this case in the Xijing Criminal Investigation Detachment has changed from Xiao Zhao to the captain of the second brigade.

To characterize a case as an accident or suicide, all reasonable doubt must be eliminated.

However, the fact that the balloon does not reach the explosion limit is enough to cause concern.

...

Graphic Investigation Room.

"The situation I just mentioned is very simple, generally speaking, the correct camera is a parallel perspective effect, that is, horizontal lines converge in the distance... This is not the case with this luminous wide angle, which will have noticeable distortion. The operation is also relatively simple, take out this image a few seconds before the B explosion, then open the PS software, select the filter - adaptive wide angle, and then set it to perspective. And then you need to add it... Kindness... Six constrained lines, so that... Well, you also need to add a rotation constraint line, and then... The rotation constraint line is vertical..."

A group of detective detectives: ╮(╯▽╰)╭

Is this how the PS software is used?

At the end of the operation, a repaired drawing is made.

"Why is this a little crooked?" someone asked, sharp-eyed.

"That's the problem", Wang Liang pondered for a while and said, "I still need to take a few more screenshots to verify it." ”

This camera is 25 frames, and the current software can't intelligently repair the video, Wang Liang took more than a dozen pictures from it, and found that there was a certain amount of crookedness.

"What could be the problem?" Wang Liang pondered.

Seeing Wang Liang pondering, everyone also thought about it.

...

"Could it be the air conditioner?" asked a new police officer next to him, weakly.

"What nonsense, Captain Wang is a computer god, so he doesn't talk much. The deputy captain of the graphic reconnaissance next to him patted the new policeman's head.

"That is, do you know who Captain Wang is, how can you not see the outdoor unit of the air conditioner?" said another old detective.

Wang Liang gradually blushed a little...

Right... It is caused by the outdoor unit of the air conditioner...

Generally, buildings are very large, and you don't need to consider things like air conditioners to draw constraint lines, but this room is not big, and if you forget an air conditioner outdoor unit, it is likely to be crooked.

Finding the problem, Wang Liang subconsciously planned to use his own methods to fool the past, then gave up the idea and looked at the new policeman, "What you said makes sense, this needs to be considered." How about you try it?"

"Captain Wang", the new policeman immediately shook his head: "I can't, I just like photography sometimes, and I'm just getting started." ”

"That's great, too. Wang Liang nodded, and then began to readjust the photo.

The captain of the detective team smiled and patted the new police officer on the shoulder.

It's more normal to get a re-made photo, and after Wang Liang made a few photos, everyone analyzed them together, and they didn't find any problems.

"Do you need to keep going?" asked the deputy head of the graphic reconnaissance team.

"Let's pick a few more time periods, the method is not difficult, you can get it, I'll go to Inspector Bai first to talk about the situation. Wang Liang didn't feel very good, not because he had just seen it from the video in the last few days, and the effect of the investigation was not necessarily great.

Wang Liang knows that monitoring is not a panacea, and it takes a lot of things to handle cases. To put it bluntly, it is to rely on white pine.

...

"You mean, no one has entered the house in advance to decorate?" Bai Song thought a little after listening to Wang Liang's story.

"Well, no one has been in except the son and daughter of the deceased. Wang Liang said affirmatively: "There was another person who passed by a few minutes before the B bombing and looked inside. ”

"What did these two men bring?" Bai Song asked.

The son brought a cigarette and two bottles of wine, and the daughter brought a balloon, a cake and two bottles of wine. Wang Liang said: "Look at the photo. ”

Bai Song looked at the photo carefully.

Because the weather is already very cold now, and it will be heated in a short time, Yao's son and daughter are wearing more clothes, but judging from their posture, there is nothing hidden in them.

The cake brought by her daughter Yao Xin is still a transparent box, and it doesn't seem like there's any problem.

The wreckage of the cigarette brought by the son was also found from the scene later, and it was indeed a state formed after the whole cigarette was burned directly.

Because the fire did not last long, the smoke was not completely burned to ashes, but the high liquor brought by the children was burned by the fire, and the wine inside also played a role in combustion--judging from the follow-up situation, Yao's death had nothing to do with these wines.

"So, why did the B bombing happen, what did it blow up?" Wang Liang looked puzzled: "According to what you said, at least a few cubic meters of hydrogen is needed." ”

"That might not be the reason for hydrogen. Bai Song pondered for a while: "Wait to see Wang Huadong and Liu Shuyuan's on-site investigation." ”

...

After Wang Liang left, the graphic investigation department continued to check all kinds of video materials, and many people got started together, picked dozens of time periods, and corrected hundreds of pictures, but still no problems were found.

This result was very frustrating, and the Zhuang detachment specially came to the office here to ask Bai Song, and when he saw Bai Song reading the transcript here, he didn't bother.

Bai Song saw several valuable information from many transcripts.

First of all, several people have proved that Yao is in arrears of wages, and there are still three months before the Chinese New Year, but he has not yet paid the wages of these workers who followed him for the last trip.

Generally, the contractor will always say that the end of the year will be settled, but once there is a default, the workers are not stupid, and now not every worker is a "waiting party", especially when it comes to their own vital interests.

In the past month, Yao's workers have had many clashes with him.

In addition, some people say that Yao's children are good to Yao, especially his son, who basically comes over every week. However, some people said that the son came to Lao Tzu to ask for money.

The latter has corroboration, that is, the police investigated the consumption records of his son Yao Lei, which is indeed several times higher than that of ordinary college students, and much higher than that of his daughter Yao Xin.

In addition, some people also said that a few minutes before B bombed, passing by this neighborhood, he saw Yao looking at his mobile phone from the window, and the candle was still lit. Because both of these are bright, they are easy to spot.

In other words, the B bomb is not because of the sudden ignition.
