But after walking around the rooftop, the footprint disappeared.

"Hey, why are they missing?" Li Jie was surprised.

Ma Weizhong and Bao Xiaohei immediately looked at Su Qing with four eyes.

Su Qing pointed to the stairs on the rooftop: "Let's go down and take a look!"

So the group of four people walked down the stairs.

This self-built building for residents is also a five-story building. Each floor has a long aisle, and each floor is divided into seven or eight small rooms, and each room has a door number.

Until Su Qing and his group of four went down to the third floor, they found that the shoe print that had disappeared before actually appeared again.

And the footprint was actually heading towards a family on the third floor.

So the four of them followed the footprint and came to the door of San07. The sound of TV could be heard inside. It was obvious that there was someone in the house now.

At that moment, Bao Xiaohei raised his hand and knocked on the door without Su Qing's order.

A man's voice soon sounded inside: "Who?"

With the sound, footsteps also sounded from the room.

Then the door of the house was opened.

This is a young man who looks just twenty-five or twenty-six years old. He is quite thin and tall.

However, when the man opened it, he saw that there were four young people standing outside the door of his house.

Of course, this is not the point, the point is that he doesn't know these four people at all.

However, the young man asked quite politely: "Who are you?"

Bao Xiaohei took the initiative and immediately showed his ID: "We are from the Municipal Bureau of Serious Crime Team."

The young man was even more confused: "Uh, are you asking me for something?"

He seemed to have never done anything.

Su Qing said lightly: "I wonder if we can go in and take a look?"

The man's mind has not turned around yet. These are people from the Municipal Bureau's serious crime team. If you want to go into your house and see, can you refuse?

Although I hadn't figured it out yet, the man nodded, then moved away from his body and invited four people in.

"Then, please come in!"

As soon as the four of them came in, they turned on the LED trace lights. Sure enough, in the man's room, they could clearly see the shoe prints tracked by them.

Soon Ma Weizhong found a pair of sneakers from under the man's bed.

"Boss, look!"

Ma Weizhong turned over the soles of the shoes and looked at them, then immediately greeted Su Qing.

Su Qing came over, took the shoe, and looked carefully at the patterns under the soles of the shoe.

That's right, the pattern on the soles of the shoes is exactly the same as the soles on the soles outside the rear windowsill of the bathroom of Zhao Juan's rental house, and the shoe printing patterns on the rooftop.

At this moment, the young man had not yet figured out the truth: "What's wrong with this shoe?"

Bao Xiaohei and Li Jie also came over.

Bao Xiaohei also looked at the pattern on the sole of the shoe, then the guy raised his hand and pointed at the shoe and asked, "Whose shoe is this?"

The young man said naturally: "Of course it's mine!"

He lives alone, will there be someone else's shoes in his house?

Su Qing smiled and nodded: "What do you call me sir?"

The young man grabbed the head: "My surname is Zhang, Zhang Shaomin!"

Su Qing raised his hand and patted Ma Weizhong and Bao Xiaohei on the shoulders: "Take it back first!"

Then Su Qing turned around and walked out.

Ma Weizhong and Bao Xiaohei grabbed Zhang Shaomin's arm.

"Mr. Zhang, it seems you have to go back to the bureau and cooperate with us to investigate!"

Zhang Shaomin still looked confused: "I, I didn't do anything?"

Bao Xiaohei smiled and said, "It's okay, when we get to the bureau, we will help you remember it slowly!"

I have to say that Bao Xiaohei, Ma Weizhong and Li Jie are still very excited. These footprints have already met. Then Zhao Juan's murder case can be said to have been solved, and what they need now is Zhang Shaomin's confession.

As long as Zhang Shaomin admits and confesses his entire murder process, they can close the case!

However, Su Qing was as calm as usual, and there was no excitement at all for such breakthrough progress.

Similarly, Xiao Jibing did not make any comments about Zhang Shaomin along the way.

Back at the bureau, Su Qing directly handed Zhang Shaomin to Bao Xiaohei and others.

In the forensic room, Xiao Jibing had already analyzed the traces of the shoe prints in the house of the deceased Zhao Juan.

Xiao Jibing quickly came to a conclusion: "Qingqing, the owner of this shoe, had a process of movement and staying in the room of the deceased."

Su Qing nodded and agreed to Xiao Jibing's analysis. Then he handed Xiao Jibing the pair of sneakers he brought from Zhang Shaomin's house and Zhang Shaomin's fingerprints to Xiao Jibing.

"Xiao Bingbing, please compare."

Xiao Jibing took it and took a look.

Although Xiao Jibing didn't ask, Su Qing still said: "It's better to test it carefully. Although Zhang Shaomin is very likely to be based on shoe prints, I still prefer the one named Kuang."

"Also, Zhang Shaomin's reaction doesn't look like a murderer who came to us when he saw us!"

When Xiao Jibing got in and got off the bus, he naturally saw the young man named Zhang Shaomin. He nodded immediately and agreed with Su Qing’s statement: “Yes, that person does not look like the murderer!”

Xiao Jibing sat in front of the computer for two hours, while Bao Xiaohei and the others also accompanied Zhang Shaomin in the interrogation room for two hours.

Two hours later, Xiao Jibing had a result.

Zhang Shaomin's fingerprints are not comparable to the half of Zhao Juan, who was not the dead, that they found.

Although the soles of Zhang Shaomin's shoes are the same as the patterns of the footprints they found, the degree of wear on them is completely different.

So, it can be seen that Zhang Shaomin's luck is really not very good. His pair of sneakers actually had the same pattern as the sole of the murderer's sneakers.

At this time, the door of the forensic room was knocked on.

"Come in!"

This is Su Qing's voice.

So the door was pushed open, and the people who came in were Bao Xiaohei, Li Jie and Ma Weizhong. The three of them had no previous excitement and ejaculation.

Bao Xiaohei's head was even lowered: "Senior sister, Zhang Shaomin said he didn't know anything about Zhao Juan, and he didn't kill anyone. The three of us asked for it for two hours. That guy just bit him to death and refused to admit it!"

Su Qing and Xiao Jibing looked at the three eggplants that were like frost. The two of them looked at each other and smiled, and then Su Qing spoke.

"You guys go and send people back."

"Uh?!" The three of them immediately raised their heads and stared at Su Qing with twelve-point confusion.

Until now, the three of them have not turned around and they have no idea what their boss means. Could it be that she forgot that Zhang Shaomin is probably the murderer!

Xiao Jibing is still kind enough.

"You three go and send people back. Although Zhang Shaomin's soles are the same as those at the crime scene, the wear level is different, so it is obvious that Zhang Shaomin is not the murderer. He should just have a pair of sneakers that are the same as the murderer!"

"Also, Zhang Shaomin's fingerprint is not comparable to the half fingerprint I extracted on the spot."

After hearing this, Bao Xiaohei, Li Jie and Ma Weizhong, look at me, I look at you, so Zhang Shaomin called for two hours of injustice, but he was not really acting, but he was really not the murderer.

At that moment, Li Jie and Ma Weizhong all looked at Bao Xiaohei.

Bao Xiaohei had been swearingly before, and this Zhang Shaomin was the murderer...

Bao Xiaohei raised his hand and touched his nose, and he felt a little embarrassed.

"Don't look at me, it's not right. Let's go. We three were together just now. Now I'm sending them back, so we three should go together!"

As he said that, Bao Xiaohei pulled Li Jie with his left hand and Ma Weizhong with his right hand, and left the forensic room together.

The three little ones just left when they thundered their backs and walked in.

"Boss, I have found out that person named Kuang. His name is Kuang Yuxin. He is 31 years old this year and has a criminal record. He was sentenced for fraud three and a half years ago. However, because the amount involved was not large, he was sentenced to five years, which was just an out-of-jail execution."

Su Qing:...

Xiao Jibing:...

After Lei Dong finished speaking, he took out another USB flash drive: "This is all the information of Kuang Yuxin, and his fingerprints are archived in our fingerprint library!"

Su Qing immediately looked at Xiao Jibing, and Xiao Jibing was also willing to do it, and immediately started operating on his computer. The man's fingertips quickly typing on the computer keyboard.

Soon, Xiao Jibing retrieved Kuang Yuxin's fingerprint information from the fingerprint library.

However, only half of the fingerprints left at the scene were left, and the fingerprints left by Kuang Yuxin in the fingerprint library were also a little blurred.

I can’t compare directly with the computer.
