California gunman was volatile but passed mental assessment
Neighbors of Ian David Long described the man who shot and killed 12 people at a country music bar as distant in public but combative with his mother inside the suburban Los Angeles home the two shared.
One ruckus in April was so extreme that they called law enforcement. Authorities brought in a mental health specialist who concluded that Long could not be involuntarily committed for psychiatric observation but worried the 28-year-old Marine veteran might have post-traumatic stress disorder.
