(Portland, OR) -- The mother of a 20-year-old Washington County woman who's been missing for a week says she'll continue searching for her daughter. Allyson Watterson's mother tells KATU she's printed out more than one-thousand posters to put up in the area as she continues her search. The Washington County Sheriff's Office announced Saturday night that they're suspending their active search for 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.
