Summary based on the NamUs case record (MP59424) and 5 other sources
In the summer of 2019, a 27-year-old woman named Heather McAlister vanished from a rural highway in Washington state, leaving behind a trail of unanswered questions. On July 3rd, the day she was last seen, Heather was reportedly experiencing a mental health crisis. She had left a home in Goldendale, Washington, and was attempting to hitchhike back to her own residence in The Dalles, Oregon. Her journey placed her on State Route 142, a road winding through the scenic but remote landscape of Klickitat County. It was on this road that law enforcement officers encountered her, walking westbound at milepost 22. They offered her assistance, but she declined their help and continued on her way. This interaction would be the last confirmed sighting of Heather. She was wearing a green and white dress and black and white Converse shoes.

The days that followed her disappearance were filled with a growing sense of dread for her loved ones. The initial hope of her safe return began to fade as search efforts were launched in the vast and rugged terrain surrounding the area where she was last seen. These searches, though extensive, yielded no trace of Heather herself. However, a crucial and perplexing discovery was made between mileposts 28 and 29 of the same highway. Searchers found her purse, which contained her identification, money, and other personal belongings. The presence of these items seemed to rule out the possibility of a planned departure, deepening the mystery and suggesting that something unfortunate had likely happened to her. The discovery of her belongings without any sign of Heather herself only added to the anguish of her family and the complexity of the investigation.

The investigation into Heather McAlister's disappearance has been ongoing since that July day, yet her case remains unsolved. Since she was last seen, there has been no activity on her financial accounts, and no credible leads have emerged to indicate her whereabouts. The Klickitat County Sheriff's Office has kept her case open, but without new information, the trail has grown cold. Heather is described as a white female with brown hair and blue eyes, standing 5 feet tall and weighing around 100 pounds. The circumstances surrounding her disappearance are particularly concerning due to her vulnerable state at the time. The case is a heart-wrenching example of how a person can vanish without a trace, leaving a family to grapple with uncertainty and the enduring pain of not knowing what happened to their loved one. The overview of the case is one of a young woman in distress who was last seen in a vulnerable situation, and despite law enforcement contact and subsequent searches that located her personal effects, she has not been seen or heard from since.
