ORLANDO, Fla. - Florida detectives are searching for a quadruple amputee they say is a "person of interest" in the shooting death of his parents.

Orange County Sherriff officials say they want to talk to 30-year old Sean Petrozzino, who was last seen Tuesday in Orlando. The bodies of 64-year-old Nancy Petrozzino and 63-year-old Michael Petrozzino were found shot to death inside their Orlando home the same day. Officials had received a call from the elementary school where Nancy Petrozzino worked, asking that someone check on her.

Police say Sean Petrozzino was last seen driving his father's red Toyota Camry. A surveillance photo taken by an ATM camera and released by officials shows him standing on his two prosthetic legs. Authorities say he is armed and dangerous.
