"There is a hole in Ran Ruzhai's head. Positioned above the back of the head, I touched the back of the head again, and there were several bags on the back of Ran Ruzhai's head, and the hair on and under one of the bags was wet. I didn't expect Ran Ruzhai to suddenly exert force, and the time for the hammer to fall was a little earlier. The results showed flaws. Ran Shixiong They are not fools, they will definitely see the flaw - no matter how Ran Ruzhai hits his head, he can't hit that place. ”

"What's next?"

"I took off my coat and sweater, wiped the blood on Ran Ruzhai's head, carried him to the bed and lay down, and then wiped the blood off the ground with my coat and sweater, and finally turned off the light, closed the door, and slowly pulled the bolt into the bolt hole with an ear rake."

"And after that?"

After that, I went home. As soon as I entered the house and closed the door, I saw Ran Shijie coming over in a hurry. ”

"What time was it?"

"About half-past four."

"Yes, I'll be in the front yard at about half past four."

"We did find that something was wrong, but because of the weakness of our hearts and the urgency of the matter, we didn't have time to think about it, at that time, we just wanted to cover up this matter, so we asked Shijie to invite Mrs. Liu here. Please Mrs. Liu, that is, I want to find a witness, otherwise, the neighbors will not be able to explain, then Mrs. Liu's eyes are not good, as long as her old man can't see the blood on my father's head, everything will be fine. But we think that Mrs. Liu is a very shrewd person. Ran Shixiong said.

"Jiang Fengqi, where are your coat and sweater?"

Coats and sweaters should be very important physical evidence.

"I threw my coat and sweater into the backstreet public toilet."

"Where is the public toilet?"

"Out of the alley, diagonally opposite." Ran Shijie said.

"How did you know there was a secret room in 186?"

"I've known about the secret room under the bed for a long time."

"When did you find out?"

"1976."

"How do you know?"

"Coincidentally, one day, I collected five copper coins on Sanshan Street, which were copper coins during the Tang Zhenguan period, and one night, when I was playing with five copper coins, one of them fell to the ground and rolled under the bed. I removed the bed and found a copper coin in a brick crevice. I pried open the floor tiles, and found a round stone underneath, so I pressed and twisted it, and I heard a 'squeak' sound, and soon, a secret door opened, and when I went down, it turned out to be a secret room, and there was a well in the secret room that had long been abandoned. ”

After the interrogation, Ouyang Ping and Liu Dayu sent away the three Ran siblings, and then escorted Jiang Feng to the public toilet in the back street. The time of the crime is January 28, and it is now February 4, not long after the time, it is estimated that the feces in the public toilet have not been cleaned up, and Jiang Fengqi's coat and sweater may still be in the manure pit.

Before leaving, Ouyang Ping asked the policeman Xiao Liu to find a bamboo pole, an iron hook and a rope.

The group went up to Mafu Street from the street entrance, and then passed through Hoop Barrel Alley.

When the comrades walked through the hoop barrel alley, they saw some people walking towards the backyard of Ran's house, they should have gone to see the excitement, and some people simply followed everyone to the backstreet.

Walking out of the alley of Hoop Barrel Lane, there is a public toilet diagonally opposite.

Jiang Fengqi led everyone to the back of the public toilet.

At the back of the public toilet there is a septic tank, which is covered with more than a dozen cement slabs. There are some gaps of different widths between the cement slabs.

Jiang Fengqi walked up to the two cement slabs, pointed to the gap between the two cement slabs with his foot, and said, "I threw it down from here." ”
