Linda Mary Garrison was 19 when she was last seen in Sumner, Washington, on November 19, 1968. She was described as five feet one inch tall, about 125 pounds, with blonde or possibly strawberry-hued hair and blue eyes. The last known activity reported was that she went for a horseback ride and did not return.

About a month before her disappearance she had been thrown from a horse and treated for back injuries, a detail noted in the case but not tied to any leads. The Sumner Police Department lists the case as open and unresolved, and investigators reportedly had very few clues to follow.

Does anyone remember Linda, her last ride, or anything from Sumner in November 1968 that could help bring new information to the case?
