Summary based on the NamUs case record (MP75400) and 2 other sources
In the small city of Sumner, Washington, the autumn of 1968 was drawing to a close when a young woman's life took an unforeseen and sorrowful turn. On November 19, 1968, 19-year-old Linda Mary Garrison was seen for the last time. A young woman with blonde, possibly strawberry-hued hair and blue eyes, Linda was reportedly last seen after going for a horseback ride. Standing at five feet one inch tall and weighing around 125 pounds, her physical presence was a familiar part of her community. The day she vanished remains a stark and painful marker in time for those who knew her and for the community that has long wondered about her fate. The circumstances surrounding her disappearance are sparse, leaving a void where answers should be.

Decades have passed since Linda Garrison disappeared, and the passage of time has not brought clarity. The limited information available paints a picture of a young woman on the cusp of her adult life, whose future was abruptly erased. Investigators were left with very few clues to follow. Details about the clothing she was wearing or any personal belongings she may have had with her on that day are not publicly known. Approximately a month before she went missing, Linda had been thrown from a horse and received treatment for back injuries, a detail that adds a layer of vulnerability to her story but offers no direct insight into what happened to her. Her case is a quiet and haunting one, a story of a person who seemingly vanished without a trace, leaving a family and community to grapple with an enduring mystery.

The investigation into Linda Mary Garrison's disappearance is handled by the Sumner Police Department and remains an open and unresolved case. The lack of significant leads over the years has left her story suspended in uncertainty, a cold case that awaits a breakthrough. For those who remember her and for a new generation of investigators, she is more than a name in a file; she is a person whose absence is still felt. The overview of this case is one of profound and sudden loss; a 19-year-old woman went out for a ride on a November day and never returned. The narrative of her life abruptly ended, replaced by a long and sorrowful mystery that continues to be a somber part of Sumner's history.
