Frank Sinatra was jailed twice in 1938 for “sex offences,” according to the New York Times. He was detained twice: once in late November on allegations of seduction and again in late December on charges of adultery. Both of these charges were eventually dropped.
A girlfriend got into a disagreement with Sinatra’s then-fiancee, Nancy, and filed accusations, which led to the initial charge of seduction. The lady who filed the initial seduction charges said that Sinatra had lured her on the promise of marriage, and the adultery charge was a milder version of the original charge.
Because neither Sinatra nor his girlfriend were married at the time of the alleged crime, the term “adultery” does not accurately describe what happened. Sinatra was 23 years old at the time of his arrest, and there is a famous mugshot photo related with the November arrest. Nancy Sinatra, Sinatra’s fiancee at the time, appears to have been unaware of, disbelieved in, or unconcerned about these allegations and charges. Nancy married Sinatra the next year, and the two remained married until 1951. Nancy is the mother of all three of Sinatra’s children. After their divorce, Sinatra married three more times.
