This is starting to look more and more like murder. Reports coming out now that suggest the police have been called to his house because of domestic issues before. Also, it turns out he's a gun nut, and a paranoid one at that, who slept with a pistol under his pillow and a machine gun next to his bed. SA has fairly high levels of crime, but he lived in a ridiculously secure and quiet complex and it's clear his paranoia and gun obsession was out of control.
Even a bizarre story that he owned two tigers but he had to let them go when they grew too big.
As a South African, this story is totally shocking. I'm struggling to wrap my head around it. Appears he may just have been a fatally flawed character with deep seated issues.
