(Portland, OR)  --  Portland police say two bodies found in Washington Park could be connected to the case of a missing 15-year-old Aloha girl.  A search-and-rescue K-9 unit discovered the bodies yesterday morning about 80 feet off the Wildwood Trail.  Police say they're not yet able to verify the identities as Annieka Vaughan and her alleged sexual abuser, 23-year-old Zachary Petersen.  Police found Petersen's pickup truck in the same area on Monday.  Vaughan ran away from home last month.
