(Portland, OR)  --  Police are suspending their search for a 20-year-old Washington County woman who's been missing for a week.  The Washington County Sheriff's Office announced Saturday night that they're suspending their active search for Allyson Watterson.  Watterson was last seen December 22nd with her boyfriend, Benjamin Garland.  He was seen later that day without her and then arrested last week on charges not related to Watterson's disappearance.  Police say Garland claims he and Watterson were hiking near North Plains when they got separated, but investigators say there's no evidence that that's the case.  The Washington County Sheriff's Office says they plan to continue investigating her disappearance.
