CONCORD, N.H.—Investigators in New Hampshire were probing for answers Sunday as to why a man shot a security guard to death at a New Hampshire psychiatric hospital moments before being killed by a state police trooper.

New Hampshire Attorney General John Formella said Saturday that 33-year-old John Madore entered New Hampshire Hospital on Friday afternoon and killed Bradley Haas, a state Department of Safety security officer who was working at the front lobby entrance of the facility.
