I mean I think it's plausible that he could have been coerced into killing himself. An offer to kill yourself and we'll protect your people or something. Or don't, and get your head stomped in and have anyone you care about hunted down. 

Plus, itd be really hard to get someone in the prison to do it unnoticed. I'd basically have to be a guard, most aren't really your assassin types. And its a lot easier to pay your average Joe to turn a blind eye than it is to pay them to murder a guy at work.

It's not a question of if he killed himself or not, it's a question of how the fuck he was able to do so as one of the biggest criminals with so much media attention. Should've been two guards on active watch, not to mention taking away anything he could use to kill himself with.  
Thus yes, he did technically commit suicide, but the "didn't kill himself" references how someone intentionally ignored the cameras, or wasn't monitoring him on purpose.
