Hours after being discharged from a mental health treatment facility, 38-year-old disabled veteran Lee Cole hiked into a wilderness area in southwest Colorado Springs with a backpack and the cellphone on which he planned to record his final message. Most of that roughly four-minute Facebook Live video, posted publicly the evening of April 23, shows a wobbly pan around a bramble-choked gully, with only a fleeting careen over Lee's expressionless face. Turn up the volume, though, and his pain is achingly clear. "I'm gonna die tonight," he says, in a taut and breathless voice, his dark pronouncement backed by a dissonant chorus of birdsong.
