Heather McAlister, 27, vanished from a rural stretch of State Route 142 in Klickitat County on July 3, 2019. That day she was reportedly in a mental health crisis and had left a Goldendale home attempting to hitchhike back to her residence in The Dalles, Oregon. Law enforcement encountered her walking westbound at milepost 22 and offered help; she declined and was last seen continuing on foot.

Search teams found her purse containing identification, money, and other personal items between mileposts 28 and 29, but no sign of Heather. There has been no activity on her financial accounts since she disappeared. Heather is described as a white female, brown hair, blue eyes, 5 feet tall, about 100 pounds. The Klickitat County Sheriff’s Office has kept the case open but no credible leads have emerged.

If anyone saw Heather on State Route 142 that day or has information about her movements, please come forward.
