Tampa, Florida -- Sky 10 hovered over a million dollar home on fire in the exclusive Avila neighborhood in North Tampa Wednesday morning.
The first 911 calls came within seconds. Investigators confirmed the home is owned by tennis pro James Blake, but they say he was renting it to Darren and Kimberly Campbell and their two children, Colin and Megan.

When the structure was safe to enter, investigators found four bodies inside, but would not confirm if the deceased are the Campbell family. But they did confirm unusual circumstances.
"On two of the victims, there is upper body trauma. We have confirmed that there were fireworks scattered throughout the house and the fire was deliberately set with an unknown accelerant," said Hillsborough County Sheriff's Office spokesperson Col. Donna Lusczynski.

The son, Colin, is the most celebrated member of the Campbell family. A standout high school baseball player coached locally by Brian Grifone, who received calls of condolences all day.
"He had dreams of playing professionally one day, and he knew that was the right path to take," said Grifone.
