Tampa, Florida -- Four bodies have been found inside the large, million-dollar Tampa home that went up in flames Wednesday morning.
During a 5:30 p.m. press conference Wednesday, Col. Donna Lusczynski of the Hillsborough County Sheriff's Office said it took firefighters several hours to extinguish the fire as hot spots continued to pop up and the blaze kept restarting. Investigators were able to finally gain access to the inside of the mansion around 3 p.m.
Once inside, authorities found the bodies of two adults and two teenage children in their respective bedrooms. While investigators confirmed the home was being rented out by the Campbell family, they say a positive identification of the bodies would not be available for several days. Lusczynski did say, however, that the family is unaccounted for at this time.
It was also revealed at the press conference that two of the victims suffered upper body trauma, but the extent of those injuries and how they were caused is not yet known. No weapons were located as of now inside the home.
Lusczynski went on to say that the fire was started intentionally by an accelerant that has not been identified at this time. Also, various commercial fireworks were found inside which is what the loud explosions likely were that neighbors reported hearing during the blaze. She also said investigators are considering murder-suicide as a possibility as to what happened and that no one else in the community is believed to be in any danger.
