Stander wasn't the manager of the complex. He was a member of the Estate Management Committee until he resigned in January 2013. The Estate Manager was Eugene St Leger Denny at the time (Dr Stipp refers to him) and still is.
In his testimony Stander says Dr Stipp arrived while he was outside trying to call an ambulance. Stander says he couldn't get hold of them. Dr Stipp sees him on the phone when he arrives. Stipp gives him the number and he calls 082911. Stipp then comes out and talks to Netcare after briefly attending Reeva. Carice then comes out too and gives Netcare directions because her father seems to have been incapable of doing this. This is the same Netcare who told OP to bring Reeva in.
Meanwhile Baba had also been sent off to call an ambulance. So that's three people that called them: OP, Stander and Baba.
From my notes of Dr Stipp's testimony
– DrS drove to OP’s house and parked behind another car that was parked to the left
– DrS saw JS talking on his cellphone and leaning against a white BMW parked in the driveway
– JS motioned DrS towards the front door of the house
– DrS went to the front door
– DrS saw CS standing in the door
– DrS told CS he was doctor and if he could be of assistance
– CS said ‘yes’ and showed DrS inside to the bottom of the stairs
– DrS saw OP kneeling by the side of RS to the left.
– DrS saw OP had his left hand on RS’s right groin and his right hand, 2 fingers in RS’s mouth.
– OP said to DrS : “I shot her… I thought she was a burglar and I shot her”
– DrS says RS had no pulse in her neck or peripheral pulse; RS had no breathing movements
– DrS says RS jaws were clenching down making the jaw lift maneuver very difficult
– DrS opened RS’s right eyelid : her pupil was fixed and dilated; the cornea was milky, already drying out
