Sneaking into a place in SA is almost a surefire way to get shot. Home burglary is the predominant crime there; they surround their houses with 8+ foot walls, electified fences on top of those walls, and razor wire on occasion. Not to mention the bars on all their windows, personal secerity firms for each neigborhood (since the police are virtually useless), etc. Hell, one filthy rich guy I met when I was there said his home was robbed 5 times in the 8 years he has lived there and twice he was held at gunpoint. Sneaking into someone's house in that country is not a bright life decision.
All that being said, I'm not suggesting that this was an accident or anything (seems as though there was a history of domestic violence between these two).
Side note on how useless the police are there: my buddy and I were playing some CoD and drinking a few beers when he decided he was bored and we required a trip to the strip club. He had recently lost his rear tags for his truck (for some reason they have little rivet guns to attatch your plates rather than something more secure). On our way we got pulled over (clearly having been drinking). The cops pulled him out, talked with him for about 20 minutes, accepted a bribe of what would be about $18 US and sent us on our way...sort of. When they were done they asked us which club we were going to and told us to take our time, they would wait around outside and follow us home to make sure we made it there safely.
