GRANITE BAY (CBS13) – A man is behind bars in Placer County after he allegedly stole a woman’s car keys and cell phone and tried to take her car.

Just before 5 p.m. on Tuesday, the 78-year-old woman was sitting in her car with her grandson outside of her granddaughter’s exercise class at the Granite Bay Park on Douglas Boulevard. That’s when the suspect, 32-year-old Eurado Amparan, walked up, grabbed the woman’s cell phone and car key and forced his way into her car, according to a Placer County Sheriff’s Department statement.
