1. There's at least one hour missing from the surveillance tapes of ALL FOUR cameras that showed the gym where Johnson died.

2. Johnson supposedly suffocated after falling head first into a rolled up gym mat in an attempt to retrieve sneakers which had fallen into it. But the first crime scene photo in this article shows Kendrick's stockinged feet with a pair of sneakers seemingly thrown in after him:

3. Also, per that article, two different black sneakers are shown in police crime scene photos yet one was not collected as evidence.
4. A second autopsy paid for by Johnson's parents reached a far different conclusion than the first one: that Kendrick had sustained a blow to the right side of his neck that was "consistent with inflicted injury." Where the state autopsy found the cause of death was positional asphyxiation, the second concluded he died as the result of "unexplained, apparent non-accidental, blunt force trauma."

5. When Johnson's parents had his body exhumed for the second autopsy, it was discovered that every internal organ from his pelvis to his skull had been removed and the corpse had been stuffed with old nespapers and department store circulars.

What his parents have gone through merely trying to find out the truth of their son's death is simply unimaginable. But discovering that his body had been stuffed with trash ...??
So, yeah, count me as a doubter.
