Seduction and adultery
"In 1938, a 23-year-old Frank Sinatra was arrested in Bergen County, N.J. on charges of seduction and adultery. According to the FBI reports, "On the second and ninth days of November 1938 at the Borough of Lodi" and "under the promise of marriage" Sinatra "did then and there have sexual intercourse with the said complainant, who was then and there a single female of good repute." This, the charge stated, was "contrary and in violation of the revised statute of 1937." The charges were later dismissed when it was determined that the woman involved was married."
