(Beaverton, WA)  --  Two Beaverton police officers who shot a 29-year-old woman to death after she pointed an unloaded rifle at them won't face criminal charges.  The Washington County District Attorney's Office says officers Dan Coulson and James Beane were justified when they shot Chelsea Fresh outside her home last November.  Officials say Fresh moved toward the officers with the weapon.  Authorities say it wasn't until after she was shot that police found her gun wasn't loaded.
