City: Attack, Fat House

　　Xiao Yao stood in the hall and looked carefully.

　　The villa is very large, with two floors up and down, about [-] square meters.

　　The corner is good, the mountains and the water are on the back, and it can barely be regarded as a 'sea view room'.

　　The first floor is the hall, living room, kitchen, study and storage room.

　　In addition to a hall on the second floor, there are three bedrooms, all with separate bathrooms.

　　After investigating from top to bottom, Xiao Yao found nothing wrong.

　　Back on the first floor, Xiao Yao walked out of the villa and looked around again.

　　Still nothing was found.

　　Could it be that he was teleported into this villa?

　　Xiao Yao frowned.

　　Ability: Cat's Eye!

　　Skill: Track!

　　Ability: Details!

　　With three abilities activated, Xiao Yao took the trouble to re-investigate the villa.

　　Once, twice, until the third time.

　　Xiao Yao stopped at the back outside the villa, standing in front of a window sill, staring at the edge of the window.

　　"What did you find?"

　　Ye Qingzhu followed her husband's gaze and looked at the edge of the window.

　　"There's something wrong with the dust on it."

　　Xiao Yao stretched out a finger and wiped it lightly, looking at the thin layer of dust on his finger.

　　"Isn't it normal that dust will accumulate on the window edges outside the villa?"

　　Ye Qingzhu was also somewhat incomprehensible.

　　"Very abnormal."

　　Xiao Yao chuckled, came to another window not far away, stretched out his hand, and wiped it.

　　When he put two fingers together.

　　It can be clearly seen that the dust on one finger is very thin, and the dust on one finger is very thick.

　　"Same windows with different levels of dust accumulation?"

　　As an old criminal investigator, Xiao Yao reminded him a little, and Ye Qingzhu could figure out the key in an instant.

　　"If you were cleaning our house, would you only clean the dust in one window alone?"

　　While speaking, Xiao Yao walked to the window not far away and wiped it with a finger.

　　The dust is equally heavy.

　　Subsequently.

　　The couple went back to the window with the least dust accumulation.

　　"Someone cleaned this window specifically."

　　Ye Qingzhu spoke coldly, with a very positive tone.

　　"Ah."

　　Xiao Yao nodded, "It can be in and out, or it can be to cover up something. The murderer is quite professional, and it is estimated that he has watched a lot of Conan episodes!"

　　"..."

　　Ye Qingzhu was speechless and wanted to beat her husband.

　　When investigating the case, you are still joking, is it really good?

　　"just kidding."

　　Xiao Yao brushed off the dust on his fingers, gave Ye Qingzhu a kiss, and turned to look behind the villa.

　　Behind it is a low wall with added guardrails.

　　Going to the guardrail, there is a small metal door, which is locked from the inside and cannot be opened from the outside.

　　The ash buildup on this metal doorknob was just as different from the ash buildup on the rest of the small door.

　　The couple looked at each other.

　　Xiao Yao opened the door and the two walked out.

　　Outside the fence are sitting hills and planted woods, but there are no roads.

　　Because these are man-made greenery, the trees do not need to be pruned, and the hills do not need to be maintained.

　　There is no road, but it does not mean that people will not walk.

　　There is an artificial drain on the edge of the hill.

　　The cement construction is not short, and there is still water in it.

　　"The murderer entered from here."

　　Ye Qingzhu looked complicated, "Only walking in the water can cover up any traces of footprints."

　　"Yes."

　　Xiao Yao nodded, "Not only that, it may also be that the murderer carried the suspect, walked from here to the villa, entered the villa through the window, and faked the suspect's murder."

　　If Xiao Yao hadn't noticed that the dust on the windows was different, he wouldn't have thought of it.

　　Even old criminal investigators can hardly find these suspicious points.

　　This is not to blame for the negligence of the police officers who originally surveyed the scene.

　　without any traces.

　　Who could have imagined this way of entering the villa?

　　How many people will notice the thickness of the dust on the window edge?

　　The couple followed the drainage channel and walked into the distance.

　　In about ten minutes, I walked past three villas and came to a residential road.

　　This road is an emergency passage within the community.

　　There is an emergency gate not far away, which is specially used for the passage of fire engines and ambulances.

　　The gates are closed on weekdays, and there are no security guards to look after.

　　When Xiao Yao came to the door, he found that it was an electronic magnetic lock.

　　As long as you have the owner's card, you can swipe it open.

　　Outside the gate is a small road leading directly to the road in the distance.

　　There is surveillance on a street light.

　　The surveillance video has been checked by the police and there is nothing suspicious.

　　Is it really not suspicious?

　　Xiao Yao looked at the camera installed on the street light pole about three meters away.

　　Let the security send a ladder and come to the surveillance station to check.

　　Doubt arose.

　　The ash accumulation on it is very thin, and it has been wiped off in about a month or so.

　　This kind of monitoring will someone clean up the dust?

　　funny!

　　Ask the members of the serious crime team to send a Polaroid camera and take a photo of the night scene from the angle of monitoring. After finding a simple stand, place the photo in front of the monitor and adjust the angle.

　　When everyone returned to the monitoring room and saw the monitoring display, they were all stunned.

　　On the monitoring screen, what is actually displayed is the normal monitoring screen on weekdays.

　　However, everyone knows it.

　　At this time, the picture you see is the picture given by the camera when taking pictures.

　　"Compare the surveillance footage before and after the incident."

　　Xiao Yao narrowed his eyes, "The light is different, and there is a big gap between the photo and the real surveillance video. When replacing the screen, there will definitely be an abnormality, look for it carefully!"

　　PS: Dear readers, it’s the beginning of the month, give me monthly passes and flowers, thank you! .

Chapter 254

　　Surveillance footage was reviewed.

　　Some night thirty-two days ago.

　　Sure enough, an anomaly was found.

　　During a certain period of time, the video footage suddenly blurred for a while, and then became clear and bright. If you didn't look carefully, you couldn't see anything wrong.

　　Because Xiao Yao made an 'experiment', everyone knew that the video had been replaced.

　　Therefore, the video does not capture anyone entering or leaving the emergency door.

　　Combined with the time of the incident, it can be inferred that the time when the video screen was replaced was between one and a half to two hours before the incident.

　　By time, monitoring by block.

　　Clues were quickly found.
