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 latest news from around North Texas.
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.
