Details of Disappearance

Biocca was last seen in Santa Rosa, California on January 20, 1950. He left the house at 8:00 a.m., after breakfast, to talk a walk. He didn't take a raincoat with him and his son thought he would be back within an hour. He never returned, and fourteen hours later his family reported him missing.

Biocca may have traveled to Seattle, Washington after his disappearance and possibly stopped in Eureka, California on the way. He has work experience in farming, in the nursery business and as a cook. His case remains unsolved.
