Knoxville (WVLT) - They haven't closed the books on it yet, but investigators say it's looking less likely that arson or vandalism is behind a fire that destroyed 3 cars, and damaged four more at Rodgers Cadillac-Saab overnight.
911 got a call just before 1:45 Wednesday morning that cars were burning in Rodgers' detail lot.
That description made firefighters suspicious at first.
Since noon, though, more information is leading investigators in a different direction.
"They have determined it did start in a single car. The investigation's going to continue as to how it started, but we're thinking right now, electrical is the direction we're going in,” says Captain Darrell Whitaker from Knoxville Fire Department.
The dealership's diagnostic computers could give firefighters some answers.
But they won't be available until Thursday.
Only one vehicle, belongs to Rodger’s Cadillac, the other six were customer cars, in for repairs.
