Four bodies have been recovered from the burnt out home of tennis star James Blake Thursday morning.
The victims were described as two adults and two teenagers, Hillsborough County Sheriff's Col Donna Lusczynski said.
She described the fire as unusual and said there were "various fireworks" throughout the Tampa Bay-area home.
Two of the victims appeared to have suffered from upper-body trauma, but Lusczynski didn't indicate which ones or give any more details.
She also said no weapons had been found and that murder-suicide was a possibility.
Former tennis standout James Blake, a former world No4 and three-time Grand Slam quarter-finalist who retired from playing professional tennis last August after a 14-year career, had been renting the home to a family for about the past two years, and was not there at the time of the fire, Lusczynski said.
She identified the renters as the Campbell family; voter registration records identified them as Darrin Campbell and his wife, Kimberly.
Both children, Colin, 19, and Megan, 16, attended Carrollwood day school, and the principal reportedly said this afternoon that they will be missed. Guards were posted at the front gate, turning away visitors, Fox 13 reported.
TV reporter Meredyth Censullo, formerly of ABC, reported some bizarre details to the story.
She cited a source as saying the bodies found in the burning mansion "had heavy duty fireworks wrapped around their heads."
