Xiao Jiang Yingzi covered her stomach and shouted to go to the toilet, Wang Nan only thought she was going to be a demon and turned a deaf ear to her words, but after hearing a few popping sounds, a bad smell made Wang Nan unable to resist.

Stinky is just one word.

Wang Nan had to take out the gun and go to the women's toilet with Xiao Jiang Yingzi, there was only one door in and out of the toilet, he guarded the door, and it was impossible for Xiao Jiang Yingzi to escape.

But who knows, after Xiao Jiang Yingzi entered the toilet, she still heard a little noise at first, and gradually stopped moving completely.

Wang Nan knocked directly on the door to call someone, but no one answered inside, in desperation, he had to rush in, squatting pit by squatting pit to find, and only after finding the end did he see Xiao Jiang Yingzi in the back squatting pit.

Xiao Jiang Yingzi actually fell down in the squatting pit, her head down, her buttocks pouting high, how wrong she looked at that posture.

It's like a dog eating is.

Wang Nan screamed twice, but Xiao Jiang Yingzi still didn't react, he chuckled in his heart, and immediately stepped forward to drag someone, only to find out that Xiao Jiang Yingzi's head was actually stuck on the bottom.

The toilets, men's and women's toilets are all long rows of rectangular potholes, which is easier to clean, and the pressure pipe water is flushed out directly, from front to back, and the filth can be flushed directly into the pipe at the end, and the septic tank can be discharged along the pipe

The dividing wall only played an isolating role, the wall was two meters five or six high, and it was about twenty centimeters from the top, and Xiao Jiang Yingzi's head was stuck between the dividing wall and the hole.

Eiko Koe died like this.

In an eerie and humiliating pose.

But she was the only one in the women's toilet at that time.

By the time Wang Nan reacted and rushed into the men's toilet, the men's toilet was empty.

There are footprints on the wall of the men's restroom, and there is a mark on the wall where someone has fallen on their stomachs.

The person who killed Xiao Jiang Yingzi climbed to the separation wall from the men's toilet, and then it was the time to flush the water every ten minutes, and the sound of flushing drowned out the sound of him climbing over the wall and jumping down, or his hands and feet were so light that Xiao Jiang Yingzi didn't have time to find out at all, he was pressed into the dung pit and drowned.

Then, after doing all this, he turned back and swaggered out of the men's restroom.

This is Wang Nan's inference, but after Xu Weiguo came to see it, he shook his head directly.

"You only notice that there are footprints on the walls on both sides, and you think that this person is the one who came from the wall of the men's toilet to kill, but you don't notice the chronological order of the footprints on both sides.

I am contrary to your opinion, I think this person was originally in the women's bathroom, because you are a man, when Xiao Xiaoyingzi entered the women's bathroom, you didn't come in to check at all, only chose to guard the door, so you can't confirm whether there were other people in the women's toilet at that time, right? ”

Wang Nan looked puzzled.

"What does the battalion commander mean is that a woman killed Xiao Jiang Yingzi first, and then stepped on the wall from the women's toilet, and climbed to the men's toilet through the distance between the wall and the roof? But that's not right, if she goes up from this side and goes down from that side, the footprints on the wall over there should be toe down marks, not toe up. ”

"The crouching mark at the top of the wall, if you look closely, she actually turned around on it, and then kicked the wall like that against the wall and fell to the men's bathroom.

Because if you come up from the women's toilet and turn her back to the wall, you can't leave a complete toe footprint on the wall, unless she is perpendicular to the wall at the time. The walls are standing, how can one stay vertical? So this toe down near the full shoe print is fake, just to cover up the footprint of the toe up underneath.

In addition, the sound of facing down against the wall is much quieter than the sound of landing with your back to the wall.

So that's why you didn't notice anything out of the ordinary.

The murderer was a delicate, courageous, extremely light woman with strong calculations.

Immediately check the patients on this floor and the doctors and nurses in charge of this floor, corroborate each other, and see who is not in the ward and post during this time? ”

This is the fourth floor of the inpatient department, there are a total of ten wards, each ward has four beds, there are two doctors and four nurses in charge of this floor, and there are twenty-three patients on the fourth floor today, a total of twenty-nine people have been inquiring for more than an hour.

According to their interrogation records, they were compared one by one, corroborated each other, and screened, and another hour passed.

The initial screening result is that there is no suspicious person.

At the time of the murder, the doctors and nurses were all on their posts, and the patients were in their respective beds, and basically there were people who proved for themselves.

Wang Nan was dumbfounded, and Xu Weiguo frowned slightly.

This person chose the toilet as a killing place, and in just a few minutes, he killed someone cleanly and escaped, and no one noticed it at all.

After Xiao Jiang Yingzi entered the women's toilet, Wang Nan didn't see anyone else entering, so she could only wait in the toilet in advance.

So how was she sure that Eiko Koe would definitely go to the toilet?

Xu Weiguo checked the things in Xiao Jiang Yingzi's ward again, and found the residue of laxatives in the cup where she had drunk water.

If Xiao Jiang Yingzi drinks something containing laxatives, he will definitely go to the toilet, but this glass of water Xu Weiguo remembers that Xiao Jiang Yingzi had drunk before he arrived.

Wang Nan said that when she tied up Xiao Jiang Yingzi, Xiao Jiang Yingzi said that she was thirsty, and Wang Nan poured water for her.

After Wang Nan tied people up, there was only half an hour between Xu Weiguo and Li Jincheng.

In this half an hour, because the person had been tied, Wang Nan went to pee by himself, and it was a few minutes before and after, and then he personally guarded the door of Xiao Jiang Yingzi.

Therefore, to sum up, the person who wanted to kill Xiao Jiang Yingzi had already moved to kill and prepared before he knew that Xu Wei would interrogate Xiao Jiang Yingzi.

The motive for this murder is not easy to investigate.

If it is a person who premeditated the murder after the interrogation, it can be speculated that it will be the revenge of the Legon House or simply the Beacon House.

But before she tried this little Jiang Yingzi, she was just a wandering warbler, a wandering warbler with a tragic background and serious injuries.

Who would move so much effort to kill a wandering warbler with such a humiliating posture and way?

Not to mention the people coming and going in the hospital during the day, the difficulty of killing people is countless times higher than killing people at night.

For a while, Xu Weiguo couldn't figure this out.

Why was she in such a hurry to kill Eiko Koe? At such a risk?

Could it be that she knows the true identity of Eiko Koe? Do you know that if you don't kill Xiao Jiang Yingzi as soon as possible, there will be more serious consequences?

"Hey, Weiguo, what are you doing standing here, alas, I won't tell you, I want to go to the toilet first. The toilets on the second and third floors were blocked, so I had to run to the fourth floor again. ”
