SAN JOSE — A 72-year-old San Jose man has been identified as the driver killed after his station wagon fell about 400 feet down a steep hillside near a city landfill last week, authorities said.

Witnesses told police that around 9:30 a.m. Friday, they saw a blue station wagon go off the roadway on an elevated portion of Guadalupe Mines Road leading to the Guadalupe landfill.

The vehicle tumbled down the hillside between two segments of a hairpin turn, authorities said. Emergency personnel responding to the crash site found the driver, identified as Richard Nielsen, and pronounced him dead at the scene.

San Jose police, who are investigating, have not released additional details about what caused the crash.
