Just before he got to the tiles at the beginning of the bathroom,
he stopped shouting because he didn’t want the intruders to know where he was. He heard a door slam, which could only have been the toilet door.
He couldn’t see in the bathroom, but he did hear the door slam which confirmed for him that somebody was in there.
He was certain at this point that the intruders were going to come out.
He peered his way in to the bathroom at the entry point.
His mobility is not as good on tiled surfaces.
He kept his left arm behind him, his shoulder against the wall and his pistol raised. He was continuously watching the corner of the bathroom.
There was no light on in the bathroom. He could see that the window was open. His back was up against the wall at this point balancing himself, along the left hand side wall. He didn’t know where exactly the people were at this point.
He peered around the corner to look toward the shower.
He saw there was nobody in there. The toilet door was closed and the window was open.
Once he saw that there wasn’t anybody in there he retreated a step or two back. He balanced against the wall.
He started screaming again at this point for Reeva to call the police. He wasn’t sure where to point the firearm. He had it pointed at the toilet but his eyes were going between the window and the toilet.
He stood there for some time, not sure how long.
He didn’t know if somebody was going to come out of the toilet and attack him, or possibly somebody would come up a ladder outside and point a gun in the window and start shooting.
So he stayed where he was and screamed some more. He then heard a noise in the toilet room. He perceived that somebody was coming out.
Before he knew it, he fired four shots at the door.
