The FRONTLINE Dispatch presents: Breakdown (from Maine Public Radio, The Portland Press Herald, and FRONTLINE).

Months before the mass shooting in Lewiston that claimed 18 lives, the gunman’s family and friends were desperately trying to get him help.

His mental health was deteriorating. He was experiencing auditory delusions. And there were multiple warnings about his potential for violence, his access to guns and his threats to do harm.
