Bosch was driving from St. Charles, Missouri to Vancouver, Washington with her boyfriend in late December 2001. She was traveling in a black 1991 four-door Nissan Infiniti Q45 sedan with temporary Virginia license plates X247-375 taped on the rear plate bracket. Bosch apparently separated from her boyfriend east of The Dalles, Oregon sometime afterwards. She spoke to her parents on December 27; Bosch has never been heard from again. She was reported missing to the Ada County, Idaho Sheriff's Department. Bosch's case remains unsolved.
