In the quiet region of Southwest Washington, the story of Heather Mary Guy's disappearance has echoed for decades, a haunting and unresolved narrative that began in the winter of 1983. A 29-year-old woman, Heather was last seen on February 8, 1983, in Clark County. The evening that she vanished, she had been out at several bars in the nearby town of Camas. In the early hours of the morning, somewhere between 2:00 and 3:00 a.m., she was given a ride by her boyfriend. He dropped her off near her grandparents' home, located in a rural area of Washougal in the 38200 block of SE 70th Street. Tragically, Heather never made it inside the house and has not been seen or heard from since.

Details surrounding Heather's personal life and the specifics of that fateful night remain scarce in publicly available records. Information regarding her activities at the bars in Camas or the identity of the boyfriend who was the last person known to have seen her has not been widely disseminated. Some accounts refer to the individual who dropped her off as a co-worker, adding a layer of ambiguity to the timeline of her last known hours. Despite the passage of time, no witnesses have publicly come forward with information that could illuminate the moments leading up to her disappearance or what might have transpired after she was left near her grandparents' residence.

The investigation into Heather Guy's disappearance was initiated by the Clark County Sheriff's Office and it remains an active and open cold case. Her body has never been found, leaving her loved ones without answers and the community with a lingering sense of unease. Over the years, her case has been listed on various platforms for missing persons, a silent testament to a life interrupted. The lack of significant developments has meant that for decades, the narrative of Heather Guy's case has remained largely the same—a young woman who vanished into the night, leaving behind a mystery that continues to endure. The overview of the case is a stark and sorrowful one: a woman in the prime of her life disappears after a night out with her boyfriend, last seen just a short distance from the safety of her grandparents' home, and is never heard from again.
