I thought that they seemed like nice people who wanted to tell their story and not further incriminate OP
If he was my friend and I thought he might be innocent I'd probably do the same. Emphasise bits that he needed to be bolstered.
Nice touch about the friendly dogs
Nice touch volunteering info about how dark it was in the landing
Nice touch knowing the truth from OP's demeanour
Nice touch taking about other incidents on the estate
I didn't get why Mr Stander said that he wasn't a friend of OP's. He has described himself previously as a mentor and had gone to visit him post bail, was invited to the memorial and was the first person that OP called.
The first person that OP called
The first people I'd call after shooting someone on my property would be the police, maybe the ambulance and then family/friends
Not mere acquaintances no matter where they lived
