TAMPA, Fla. (CBSNewYork/AP) — Firefighters have found a fourth body in a burning mansion owned by former tennis star James Blake.

Hillsborough County Sheriff’s deputies said Wednesday afternoon that they spoke with Blake and he said he was leasing the home. He was not in Florida at the time of the fire.

Officials don’t know the name, age or gender of the victims inside the home and they aren’t releasing the names of people who were leasing the home.

Firefighters also saw fireworks inside the residence.

Hours after the fire was reported about 6 a.m. EDT, firefighters were still there putting out hot spots at the more than 6,000-square foot home located north of downtown Tampa.

One former Tampa television reporter tweeted the bodies “had heavy duty fireworks wrapped around their heads.”

Blake, a native of Yonkers, N.Y., retired after being eliminated at last year’s U.S. Open. He was a perennial fan favorite at the tournament held in Flushing, Queens.
