TAMPA, Fla. (AP) - Sheriff's investigators say that four people found dead in a Florida home that burned down had been shot.
    
The Hillsborough County Sheriff's Office said Thursday that autopsies were still being completed to determine how they died.
    
Col. Donna Lusczynski said the father who lived in the home bought a large amount of fireworks and gas cans on Sunday. Authorities say the Wednesday fire was intentionally set.
    
Lusczynski said it has still not been confirmed the bodies were Darrin Campbell, his wife and their two teens but they have not been accounted for.
    
The upscale home was rented by the Campbells and owned by retired tennis pro James Blake, who was not involved.
