"You mean, two people stepped on the same position one after another?" Tao Lin immediately became alert.

"The edge of the rooftop was the place where the deceased had a dispute with the criminal suspect, so the shoe prints were extremely confusing, and coupled with the interference of wind and snow, it was very difficult to identify; while the shoe prints at the entrance to the rooftop were very neat, showing only the gesture of stepping forward.

." Mo Shiqiu explained.

"Therefore, the murderer stepped on the shoe prints at the entrance to the rooftop and walked to the edge of the rooftop, and did the same when he returned, thus creating the illusion that only one person had been on the rooftop."

"Could it be that there are two patients with dwarfism living in this building, and the one we just arrested may not really be the culprit?" Yu Zijiang grabbed the words.

"But two patients with dwarfism...the probability of such a coincidence happening is too small, right?" After saying that, he sighed and shook his head.

"The probability of such a coincidence happening is of course very slim." Mo Shiqiu immediately shook his head.

Then he handed Yu Zijiang his mobile phone, which opened a photo of shoe prints in the snow. Seeing this photo, a non-professional who didn’t understand it just thought that the shoe prints on it were unorganized.

There is no reason why.

But Mo Shiqiu slightly edited the photo. The pair of shoe prints on the left were surrounded by a red frame and marked 1; the other pair of shoe prints on the right were surrounded by a black frame and marked 2.

These shoe prints have not been professionally sampled and processed, and coupled with the snowy and windy weather, the patterns on the shoe prints are simply blurry.

"The shoe prints on the snow at the edge of the rooftop look exactly the same at first glance, but they are actually slightly different," Mo Shiqiu said.

Unexpectedly, even though the shoe prints were damaged by the wind and snow and were arranged in no order, Mo Shiqiu could still tell a thing or two.

"Compared with this pair of footprints 1, the inner shoe prints of this pair of footprints 2 are deeper. The occasional appearance of a few such special shoe prints in a pile of footprints does not explain the problem, but if they appear in patches and continuously, this

The problem is huge." Mo Shiqiu said meaningfully.

Standing next to him, Tao Lin nodded slowly, understanding what Mo Shiqiu meant.

"The most important thing is that I found that in footprint 1, the left foot generally stepped deeper than the right foot, which shows that the owner of footprint 1 may have lameness." Mo Shiqiu continued.

"Due to physical development defects, patients with dwarfism, in addition to being shorter in height and smaller in body, usually also have leg or waist diseases, which will more or less affect their walking posture. Therefore, I think footprint 1 comes from just now

The man who escaped, and Footprint 2, came from a person with normal body functions." Mo Shiqiu continued his analysis.

Mo Shiqiu has not been on the roof for a long time, but he has already been able to analyze so many articles. His professional ability is really admirable.

If it were anyone else, they might just be worried about the messy shoe prints on the snow and not be able to distinguish the extremely subtle differences between them.

Tao Lin handed Mo Shiqiu's phone back. He took the phone, swiped the screen a few times, found another photo, and raised the phone in front of Tao Lin again.

The photo shows a left shoe print in the snow.

"Furthermore, the shoe prints from the rooftop entrance to the edge of the rooftop overlap perfectly. Unless you are an experienced field surveyor, there will be almost no flaws." Mo Shiqiu paused.

Then he swiped the phone screen with the index finger of his other hand and showed Tao Lin the next photo, which was also a left shoe print.

"But when we returned, there was an obvious deviation in the overlap of the shoe prints. I think... this person didn't expect that there would be police at the scene of the fall, so he was very panicked when he ran away."

"The more you rush, the more likely you are to make mistakes." Tao Lin stared at the photo and said coldly.

He could clearly see the upper shoe print in the photo. Its outline was two obvious parallel lines.

"The shoe prints were severely damaged by the wind and snow. I have to go back to the bureau quickly to do some technical restoration so that I can give you more information." Mo Shiqiu put down his phone and finally said.

"It seems that the real murderer really is someone else?" Yu Zijiang glanced at Tao Lin and then at Mo Shiqiu.

Mo Shiqiu's expression revealed confidence and determination, while Tao Lin still had a straight face. No one knew what he was thinking.

"Anyway, let's go back and interrogate this man first, leaving a few people to continue the interview." After a few seconds of silence, Tao Lin took over.

"That person went crazy and wanted to run away when he saw me. He must know something inside."

"Well, let's go first. It's almost time to close the team." Yu Zijiang nodded, and he immediately turned around and told the police a few words.

Then Tao Lin, Yu Zijiang, Mo Shiqiu and his apprentice Chen Rui left the crime scene together.

When going down the stairs, Mo Shiqiu had been walking at the front of the team. At this time, Tao Lin could deeply feel how tall he was - even though Mo Shiqiu was standing on the next step in front of him, he was almost as tall as him.

.

Mo Shiqiu walked downstairs quickly, and Tao Lin couldn't help but look at his various postures.

Finally, the four of them walked out of the building.

"How about we take my car back to the police station?" Mo Shiqiu said to Tao Lin and Yu Zijiang.

"Okay." Yu Zijiang replied readily.

"How do you know we didn't drive here?" Tao Lin's focus is always different.

"Teacher Tao lives nearby, and it's only a five-minute walk to this cafe, so it won't take a lot of trouble to drive. As for Team Yu... there is a subway station less than 500 meters away from Angel Cafe.

It’s easy to get stuck on the road when driving in heavy snow, it’s more convenient to take the subway,” Mo Shiqiu said.

"Besides, I know Captain Yu usually likes to drink a little wine when he has nothing to do, so he is very frugal when it comes to other expenses. Driving in traffic jams on a snowy day costs too much gas, so you definitely don't know how to drive."

Yu Zijiang opened his mouth slightly, and after listening to Mo Shiqiu's series of reasoning, he suddenly stopped talking.

Tao Lin also didn't speak. His face didn't reveal any emotional changes. He just stared at the man in front of him, replaying the analysis he had just made in his mind.

"Let's go, I want to quickly restore the shoe prints through technology." After Mo Shiqiu said that, he turned around and walked towards a dark brown SUV parked on the opposite side of the road.

"He specifically investigated us." The moment Mo Shiqiu turned around completely, Yu Zijiang tilted his head and said softly to Tao Lin.

"I see." Tao Lin replied coldly.

Then he put his hands in his coat pockets and followed Mo Shiqiu across the road.

When walking to the car——

"Yu Zijiang can just drive." Tao Lin suddenly said to Mo Shiqiu.

[Mo Shiqiu is so weird. Who knows if he really wants to go back to the police station or if he wants to kidnap me and Tao Lin?] As soon as Tao Lin finished speaking, something unfriendly came into Yu Zijiang's heart.
