(Portland, OR)  --  A former postal worker is facing four years behind bars after stealing thousands of dollars from mail on her mail route.  The Multnomah County District Attorney's Office says a judge sentenced 38-year-old Jamie Dent yesterday.  She was convicted of eleven counts of mail theft and one count of aggravated identity theft after stealing more than 100 pieces of mail on her route.  Investigators believe she likely was stealing mail for years before getting caught.
