TALLAHASSEE, Fla.  - The state fire marshal's office suspects a weekend fire that nearly destroyed the home of Gov. Charlie Crist's former communications director was arson.

Erin Isaac, who resigned as the governor's chief spokeswoman in November, declined comment Tuesday on the fire that engulfed the home at about 4:30 a.m. Sunday.

She and her husband were out of town at the time. After inspecting the home just hours after the blaze, Capt. Joe Steadman of the Fire Marshal's Office told the Tallahassee Democrat the fire was intentionally set and that it was being classified as arson.

No arrests have been made. Damage to the home, located in a trendy midtown area of the capital city, was estimated at $200,000.
