Yesterday, a fire at James Blake's home raised concerns about the former tennis star, even though he wasn't in the house at the time of the blaze.
Fans and investigators wondered aloud about Blake's connection to the four dead bodies discovered in his home.
Today, several questions have been answered, but many more have been raised.
The names of the victims have not yet been released, but police described them as two adults and two teenagers who were living in a home that they rented from Blake.
Police now believe the blaze was started by a fireworks collection found in the home.
Investigators mentioned the possibility that the deaths were the result of a murder-suicide but they did not specify what led them to that theory.
At this time, Blake has only issued a brief statement through his charitable foundation claiming that he was not in Florida at the time of the Tampa fire.
Blake, who was at one time one of the top tennis players in the world, retired from the game last August.
He has maintained a low profile since then, but is expected to make a public statement about the tragic incident that took place on his property as early as this afternoon.
