Alabama's state fire marshal says more work is needed to determine the cause of the fire that gutted a house owned by Dallas Cowboys linebacker Rolando McClain.
Ed Paulk says investigators from his office spent two days at the scene of the burned-out mansion owned by the one-time University of Alabama star.
But Paulk says it will likely be at least a week before authorities determine whether the blaze was accidental or deliberately set. Paulk says the structure was totally destroyed.
The brick mansion was on the market for $1.5 million when it burned Monday night on the shore at Lake Tuscaloosa.
Authorities have said the fire was suspicious because the house was unoccupied and so expensive. They also say a vehicle was seen speeding away from the scene.
