“Without getting into the really nasty details, he’s had concussions, black eyes, moved four times from base for his own protection,” says Carter’s father, Jack. “He’s been put in solitary confinement, nude, for days on end because he’s depressed. All of this is extremely traumatic to this kid. This is a horrible experience.”

Carter has been in jail since a February arrest. After Justin finished playing the online game League of Legends, where the community trash-talking can get quite toxic, court documents show he posted the following messages on a Facebook page:

“I think Ima shoot up a kindergarten / And watch the blood of the innocent rain down/ And eat the beating heart of one of them.”

Carter’s father says his son was responding to an insult by being sarcastic, and followed the message with “JK” for just kidding, but that’s disputed by police.
