Interpol Mission

"We patrolled along this line that day. Here in the first workshop, I went to the toilet..."

Gu Mingshan led Ye Jiu and Zhang Sirui, accompanied by the chief of the security section, slowly walked on the road of the production area.

"Is that the speed you usually patrol at?"

Ye Jiu asked.

This speed is really a little slow, much slower than the normal walking speed of ordinary people, a bit like taking a leisurely walk.

"Yes, we usually patrol at this speed When patrolling, you should carefully observe the surrounding conditions. If you walk too fast, you will not be careful enough. "

Ye Jiu nodded slightly.

It makes sense in theory.

Walking slowly to the second workshop, Gu Mingshan did not have any additional explanation.

Ye Jiu doesn't ask. He just follows and looks around. Instead, he feels that what Gu Mingshan said just now has a certain truth. Walking slowly, he really has more time to observe the surrounding situation.

After entering the third workshop, Gu Mingshan stopped, pointed to a toilet not far from the left, and said, "Zhang Ke went to a toilet over there..."

Ye Jiu looked at the bathroom and asked, "did he go alone?"

"Yes, alone. I just went to the bathroom in the first workshop... "

Gu Mingshan explained.

This situation is recorded in the file. Now more than a year later, Gu Mingshan still insists on this description. It can be seen that the same picture has already been deeply imprinted in his mind and will never forget it again.

However, the record in the file is very simple, and the investigators did not continue to understand it in depth.

"Pee or poop?"

Ye Jiu asked casually.

"I'm not sure. Maybe I'll have a bowel movement, but it's not too long..."

"Not too long. How long is it? How many minutes? "

Ye Jiu stares at and asks.

If Gu Mingshan didn't lie, that iron man's going to the toilet this time is actually the key to the whole case. Because only in these few minutes, Zhang Tiehan and Gu Mingshan came separately. When he came out of the toilet, he continued to patrol with Gu Mingshan.

Never since.

Zhang Tiehan wants to leave Gu Mingshan alone, which is also the only opportunity.

At the beginning, the police didn't ask the case in detail. Ye Jiu estimated that he still did not suspect Zhang Tiehan. The inquiry about Zhang Tiehan and Gu Mingshan was just a passing scene.

Therefore, this is likely to become the key details of the case, so it was ignored.

Now, ye Jiu has basically confirmed that Zhang Tiehan is the suspect. At present, he only needs to recover the case, and naturally attaches great importance to any details.

"Well, I don't remember it very well. It should be a few minutes..."

This time, Gu Mingshan hesitated and murmured in a rather uncertain tone.

"You can recall the memory carefully and cooperate with Ye Da well..."

The chief of the security section said in a hurry, with a slightly stern tone.

Gu Mingshan suddenly began to face bitterly. He recalled it carefully. He still shook his head and said, "I really can't remember clearly. I didn't pay much attention at that time..."

This can also be understood.

Who's free to watch others go to the toilet for a few minutes?

That's too abnormal!

The chief of the security section said to Ye Jiu: "Ye Da, you can adjust the monitoring records. The monitoring records of that period have been saved..."

Although the current electronic monitoring system is still very backward, the efficiency is far less than that of later generations, and the popularity is not high, but in the refining workshop, some important positions in the workshop are still equipped with monitoring.

Because of the gold theft, the monitoring records of the third workshop during that period were preserved.

However, if we want to transfer the monitoring now, ye Jiu has to return to the criminal investigation team of the Public Security Bureau of Xuefeng county. The monitoring records of this period, as important material evidence of the "128 gold theft case", have been sealed up by the criminal investigation team of Xuefeng County Public Security Bureau, which was responsible for investigating the case last year.

"I'll go to the bathroom and have a look..."

Ye Jiu then made a decision.

Scene investigation, which is a necessary course.

In view of the internal monitoring of the third workshop, Zhang Tiehan will try to avoid the camera when committing a crime. Generally speaking, the surveillance camera will not be installed in the toilet such a high degree of privacy.

As soon as he entered the men's bathroom, ye found the suspect point - the bathroom has a large window, and the glass is movable, which can be opened half way.

Ye Jiu then looked out of the window and found that as long as a man of ordinary stature, he could easily climb out of the window and come to the back of the bathroom.

The bathroom is on the first floor. The window is only one meter high from the ground, so it is not difficult to climb over.

Ye Jiu almost without any trouble, he climbed over the window and went outside.

Then, ye Jiu found another window 10 meters to the right, and another window about 5 meters away. All the windows are semi open, the same height from the ground, all up and down one meter.This means that these windows can be easily turned over.

Zhang Sirui, the chief of the security section, and Gu Mingshan all climbed out of the bathroom window. Following Ye Jiu, they came to another window. When they looked inside, they found that they were in a dead corner. From this position to see the past, the bathroom door that piece was covered by a tall column, mutual invisible.

That is to say, if on the day of the crime, Zhang Tiehan entered the bathroom on an excuse, quickly climbed out of the window, and then climbed in through the second window, and stood at the door of the bathroom waiting for him, Gu Mingshan, would not have found him.

Then, ye Jiu once again easily from this window into the workshop.

The guard section chief's face changed. Looking at Ye Jiu standing in the window, he said pale: "this, this Is that where Lao Zhang came in? "

"Very likely!"

Ye Jiu looks serious and nods.

"This is a dead corner. Gu can't see him standing at the door of the bathroom. He has at least two or three minutes to act alone

"But there are cameras on the production line..."

The chief of the security section is still a little unbelievable.

On the day of the crime, because the company held a meeting of all cadres and workers, the three workshops were empty. Zhang Tiehan can "act as if nobody else" in the workshop.

But how did he avoid the camera?

"The camera at the end of the third workshop just went bad during that time..."

Gu Mingshan suddenly cried as if he had discovered a new world, and his face became as pale as the chief of the security section.

although, with the successively killed Long Xuehua and Zhang Tiehan, and Chen Jiaqian's happy Ding Xiaoqi's arrest, Zhang's suspect is a rumor of "128 gold stolen" suspects. It has been circulating inside the gold mining company, but has not been confirmed by the official power. Everyone can only guess in their hearts.

Now, they are almost ready to sit down.

Ye Jiu used the simplest scene investigation to reveal the story of the day of the crime.
