Gayno Gilbert Smith: A Familial Mass Murderer

Background

Gayno Gilbert Smith was born on January 23, 1938, in Keokuk County, Iowa. His early life was marked by instability, moving between Illinois, Iowa, and Nebraska following his parents' divorce when he was about 12 years old. Despite academic challenges, he excelled in sports during high school and briefly served in the Marine Corps before receiving a medical discharge. By 1961, Smith was residing with his father and stepmother in Hedrick, Iowa.

Initial Crime

In October 1961, Smith's stepmother, Juanita Smith, went missing under mysterious circumstances. Her disappearance raised concerns, but no immediate evidence linked Smith to her absence. It wasn't until later events unfolded that the truth about her fate came to light.
