WATCH: Gunman who tried to break into FBI office shot dead by police

Officers attempted to negotiate with the man for many hours during the standoff, OSHP said. After negotiations failed, law enforcement moved in and used "less-than-lethal tactics" in an effort to take him into custody. The man then raised his gun toward officers and police fired on him, killing him. This happened around 3:42 p.m., OSHP said.
