FORT WALTON BEACH, Fla. (AP) — A sheriff's deputy in northwest Florida is dead after authorities say he was shot by a man who had barricaded himself in a house. Okaloosa County Sheriff's officials said deputies returned fire and killed the man. The Northwest Florida Daily News says a second deputy was injured during the Tuesday morning shooting. The sheriff's office said deputies had taken the man to a local hospital for a mental examination twice Monday. Early Tuesday morning, the man barricaded himself in a house with a shotgun. A negotiation team tried to talk him out at 6 a.m. and the shooting happened shortly afterward. Officials did not immediately release the names of the deputy or the man in the house. A news conference was scheduled later Tuesday.
