TAMPA, Fla. (AP) - Investigators continue to process the scene of a fire at a million dollar home owned by former tennis star James Blake where the bodies of two adults and two teenagers were found.

Officials say the early Wednesday fire inside the home in Tampa's exclusive Avila neighborhood was intentionally set.

A Hillsborough County Sheriff's official says Blake rented the home to the Campbell family. Voter registration records identified them as Darrin Campbell and his wife, Kimberly, but investigators say they won't know the victims' identities until preliminary autopsies are completed.

Col. Donna Lusczynski described the fire as unusual and said there were "various fireworks" throughout the home. Two victims suffered from upper-body trauma, but Lusczynski didn't indicate which ones or provide other details.

Officials say the Campbells were unaccounted for Wednesday.
