Chapter 199 (1/2)

Characteristics of the killer: height 178-180 cm, weight 70-71 kg, foot length 25.5-25.8 cm, arm length 59-60 cm, leg length 93-94 cm, age 25-30 years

Cheng nuogan eliminated some kinds of complex data reasoning in his mind, and ”time backtracking” was the scene that happened on the rooftop at that time.

Finally, according to the reasoning, we can get the characteristics of the killer.

Each of the data, Cheng Nuo is not a random guess out of thin air, but through rigorous reasoning, combined with which series of field data, the final calculation of the data.

It's done!

Cheng Nuo snapped his finger.

Easy!

”Captain Yang, I already know the specific characteristics of the murderer.” Cheng Nuo turned and said to captain Yang, ”the surveillance video of the shopping mall should be in your police station.”

Cheng Nuo handsome wipe a hair, fork waist, confident words came, ”next, let my detective - nonan, to help you, find the real killer!”

…………

Half an hour later.

Captain Yang and Bai Yan take Cheng Nuo back to the police station.

They still can't believe that Cheng Nuo can only rely on one Oh, no, it's half a footprints, which can analyze the various body features of the murderer.

This kind of operation is a matter of fact.

Even if it is more than ten years of experience in the industry, but also really special did not see.

There is no need to say about Baiyan.

It seems that the case of the shopping mall falling from the building can certainly be incorporated into a major case.

If he can deal with this case perfectly and arrest the real killer at large.

With this achievement, he is enough to join the mysterious organization.

But now

According to the current momentum, 80% of his achievements will be taken away by Cheng Nuo again.

Bai Yan's mood now, with a kind of egg sadness.

Is he easy?

For two months before, he had been in the middle of a conversation with a little thief who stole a battery.

It's not easy today, but finally we have to wait for a big case.

But the person who is in the limelight is not himself, but the guy who makes him hate.

Come to the police station, Captain Yang immediately led Cheng Nuo to the office, and then turned on the computer to call out the surveillance video of the mall.

The surveillance video shows the entrance to the 14th floor.

From the monitoring screen, you can clearly see the appearance of each person who goes up or down from the 15th floor.

”No problem?” Captain Yang asked in a somewhat distrustful tone.

Cheng Nuo sits on the chair in front of the computer and makes a reassuring gesture to the captain Yang behind. ”Captain Yang, don't worry.”

”If you give me one hour, the murderer will be exposed to my eyes!”

Since Cheng Nuo said so, Captain Yang is not good to continue to tangle.

He and Bai Yan looked at each other, nodded, ”that, Cheng Nuo, this case, depends on you!”

Chenobi made an OK gesture and turned on the surveillance video.

The opening time of the shopping mall is at 8 a.m.

The specific time of the dead Han Xiaoxiao's fall was at 10:52 a.m.

From the monitoring screen on the 14th floor, we can see that Han Xiaoxiao walked up the 15th floor at 9:36 a.m.

In other words, Han Xiaoxiao spent more than an hour upstairs before being pushed down by the murderer.

In this more than an hour of time, what happened, I am afraid, in addition to the murderer himself, and the dead Han Xiaoxiao, I am afraid no one knows.

Because Cheng Nuo is not sure, the time when the murderer went to the 15th floor was before Han Xiaoxiao or after Han Xiaoxiao.

Can't help, Cheng Nuo can only watch from the 8 o'clock monitoring.
