Los Altos police officers handed over their investigation of the 20-year-old driver who struck and killed a pedestrian on San Antonio Road April 2 to the Santa Clara County District Attorney last week for further review. The district attorney had not yet responded to police Monday afternoon, a police spokeswoman said.

The investigation is routine procedure in collisions involving a death. The district attorney will determine whether the action of the driver should result in manslaughter charges based on the police report.

The driver’s name is being withheld pending the results of the investigation. He was not cited at the scene of the accident.

Sgt. John Hughmanick said police had good information, but would not release any findings until the district attorney decides whether to pursue any charges.

Both the driver and the pedestrian were Los Altos residents.
