Authorities say Florida man who shot deputy had threatened police before November 22, 2014: This photo shows a home where authorities said a gunman set his house on fire and fatally shot the first deputy who arrived in Tallahassee, Fla. TALLAHASSEE, Fla. - A man who had made previous threats against police set his house on fire Saturday and ambushed the first sheriff's deputy who responded, fatally shooting the deputy and wounding another before he was killed by a police officer who lives nearby, a law enforcement official said. The man's name and address had been entered into a law enforcement computer system because of previous threats, but the 911 dispatcher who entered the fire call put in the address of a neighbor who reported the blaze, so the alert wasn't activated and the Leon County deputy who responded first had no warning, said the official, who spoke on the condition of anonymity because they weren't authorized to release the information. The gunman was hiding outside the house when the deputy approached about 10:15 a.m., the official said. He shot the deputy from behind, shot him again after he fell and then took the deputy's gun. The gunman then tried to take other weapons from the deputy's car, but they were locked down, said the official said, who had spoken to law enforcement officials handling the case. The gunman, who lived at the end of a cul-de-sac, then shot another deputy, who escaped serious injury because of a bullet-proof vest. A Tallahassee police officer getting ready to work the Florida State University football game heard the shots, ran outside and fatally shot the gunman, who was hiding as other deputies and officers approached, the official said. The names of the gunman and the dead and wounded deputy have not been released. Details of the gunman's previous threats to police officers were not available. The shootings were captured by surveillance video cameras in the neighborhood, the official said. Pockets of flames could still be seen in the smoldering wreckage of the destroyed home hours after the fire was set. As night fell in the middle-class neighborhood, investigators sifted through the rubble with shovels under the bright glow of spotlights. The official said authorities didn't think anyone was killed in the fire.
