KLAMATH FALLS, Ore. – A possible sexual assault caused an Amtrak train bound for Portland to be delayed for about six hours Sunday. Witnesses said a young woman was harassed by two men who were questioned by police, but not taken into custody. Since the train was moving, authorities now are trying to decide who has jurisdiction. It may be some point between Klamath and Lane counties. The Lane County Prosecutor’s Office has the case now for review and the investigation is ongoing.
