San Antonio fire officials are investigating what they call a suspicious fire that damaged two parked vehicles.
The fire broke out around 12:30 a.m. in the 400 block of South Hamilton on the West Side.
San Antonio firefighters first thought they were responding to a building fire, but arrived to find a Ford F-150 pickup truck and a Ford Mustang both burning from the engine compartment.
A witness says a white Chevrolet was seen leaving the area shortly after the fire started. No injuries were reported.
