Actually the first coroner's report came back saying that the kid died of sickle cell trait.
Watch the video. One guard is covering the boy's mouth and another is holding ammonia salts up the boy's nostrils. Where'd the guards get that?
Was he fighting to get free or fighting to breathe? Eventually the boy slumps and is passed out. Second medical examiner says the boy died from suffocation, probably from the ammonia fumes.
It's taken nearly a year to get anyone at all charged in this horrible case, and there have already been a couple of threads on it.
"Let the system work"? So far, it's failed this boy and his family completely.
Here's the link to the original thread about this news story, with links to the actual video. Warning: it's very hard to watch.
