Police originally received a call to a rollover crash in the 3400 block of East Ruby Hill Drive at about 12:21 a.m. Oct. 17, according to Pleasanton police Sgt. Robert Leong.
On arriving, 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. the same morning, telling them the 19-year-old had returned to his home.
