Brace yourselves... Here come the conspiracy theories.
I'm sure you've noticed that I don't tend to delve into the "conspiracy" realm too much...
On this particular one, I'm not sure I'm willing to immediately dismiss foul play on this one.
It's quite possible that he didn't want to "do the time" he had coming and offed himself, that's not unheard of for people facing serious time for sex crimes (as they often get the worst treatment from inmates in prison).
The part that needs some answers provided, was the fact that it happened when he's been (or was supposed to be) under close suicide watch for 3 weeks after they found marks on his neck and couldn't determine whether or not it was self-inflicted or the result of assault by another inmate.
Based on the guards reporting "we found him Saturday morning"...which worded that way, makes it seem like they hadn't checked up on him in quite some time, and if he found something in a suicide watch observation cell, the guards were either asleep at the wheel, or the facility he was in has one of the most relaxed suicide watch protocols I've ever heard of.
Usually the suicide watch observation cells have only a mattress, any stray pieces of fabric are removed before the inmate is put in, they're given only a thin paper gown to wear, and the cells are monitored by CCTV 24/7 and visually inspected every few minutes by a guard who's job is nothing more than constantly walking back and forth by the cells looking into to make sure the inmates aren't engaging in self harm.
The protocol is typically even stricter for high profile inmates or inmates who've previously been suspected of attempted suicide (He was both)
While it's not unheard of for some inmates who've found crafty ways to circumnavigate these safeguards and still off themselves due to either negligence or just smashing their own head against the wall or floor hard enough that they "get the job done", it's also not unheard of for foul play to occur in correctional facilities either.
I'm not jumping to any conclusions one way or the other yet...I'd like to see guards that were on-duty called in to testify.
