Pleasanton police are continuing to investigate a single-vehicle crash early Thursday on Ruby Hill Drive.
The call to the 3400 block of E. Ruby Hill Drive at about 12:21 a.m. originally came in as a rollover crash, according to Pleasanton police Sgt. Robert Leong. On arrival, police found the car engulfed in flames, but no driver was in sight.
Leong said the initial report of a rollover was mistaken.
"It looks like it hit some kind of curb," he said. PG&E was called out there, some water folks were called out."
While police were on the scene, a man arrived and told them his 19-year-old son was the driver, but refused to give the teen's whereabouts.
Police received a call at about 6:40 a.m. today that the 19-year-old had returned to his home. Meanwhile, Leong said, police are hoping for witnesses who might say who else was in the vehicle.
"We're concerned that if there was anybody else in the car that they're all right, their health and safety," he said.
The collision remains under investigation. Anyone with information is asked to call the Pleasanton Police Department at 931-5100.
