Barry Kirk Pinder, 21, was found dead on June 18, 1974, at a campsite in MacKerricher State Park in Mendocino County, California. His body was discovered under a picnic table and an autopsy concluded he died from blunt force trauma.

Witnesses said three to four males were at his campsite the night before and a motorcycle was present; that motorcycle was missing when his body was found. Pinder had been traveling from Florida and investigators at one point pursued leads into the San Francisco area. His stolen motorcycle and other possessions, including a Bible, were never recovered. The case remains unsolved and has been discussed in connection with violence and drug trafficking linked to the biker scene in the region during the 1970s, but the assailants and motive are still unknown.
