Jack Wagner was involved in a 3 a.m. brawl at the Hollywood Crescent Athletic Club on March 26, 1927, that left actor Eddie Diggins, 24, fatally wounded from a stab wound. The Crescent Club was a speakeasy and Wagner, Diggins, film comedian Lloyd Hamilton, bootlegger Charles Meehan, Meehan's wife, Irene, and actor John Sinclair had been drinking. Diggins started a fight with Wagner and Charles Meehan intervened. Although Meehan was suspected of wielding the knife, police made no arrests following an inquest the next day in which a Coroner's jury determined "a sharp instrument in the hand of a person or persons unknown to us, with homicidal intent," killed Diggins.
