Man describes possible sighting during childhood in Hinkley Basin

April 1958 Noon Aptos, Santa Cruz County, California 2 witnesses

Account

Two boys were riding bicycles down an old fire road when the witness slowed for mud and saw a dark brown man-shaped figure step from behind a redwood. The figure ran down a steep slope toward a creek while the witness heard two-footed steps on leaves for about two minutes. A companion riding behind also glimpsed the figure.
