In November 1958, Frank Duncan’s pregnant wife, Olga Kupczyk, disappeared without a trace from their Santa Barbara home after enduring months of abusive treatment from her mother-in-law. A short time later, Frank’s marriage was inexplicably annulled after his mother, posing as Olga, showed up at the local courthouse with a man she’d hired to pose as her son, Frank.
