Cameras generally don't point inside prison cells. The ones in the prison he was at didn't. They wouldn't have seen anything at all if he had killed himself - which, according to the official release, is exactly what they found. Only one of the cameras was actually down when he died. The other had data on it that was recovered. You don't have to believe the official release, and I don't either without corroborating evidence, but in order for a hitman to infiltrate a prison of all places, there'd have to be a lot more going on than one camera being down. So either way, the cameras were a non-issue.

The guards simply lied about checking on him. Is it really difficult to believe that two black prison guards charged with watching a white millionaire decided not to bother? They couldn't have given two shits about his well being. He's the oppressor after all.

And even if he did kill himself "voluntarily" because he's being blackmailed ... that's not voluntary!

Technically, I never said he killed himself voluntarily. Just that he killed himself.
