Ana Cumpănaș or Anna Sage, nicknamed Woman in Red (1889 – April 25, 1947), was a Romanian prostitute and brothel owner in the American cities of Chicago and Gary, Indiana.

[4][6][8] As Dillinger was rumored to have killed two East Chicago Police Department officers on May 24 of that year, a large reward had also been offered for his capture.

[10][13] Famous as the "Woman in Red", Cumpănaș reached the status of cultural icon in the United States in the years following Dillinger's death.

[15] On the night of Dillinger's death, an unknown chalked a pavement near the Biograph Theater with the epitaph: Stranger, stop and wish me well, Just a prayer for my soul in Hell.

She has been portrayed, albeit not always as Anna Sage, by several actresses including: Ann Morriss (as Mildred Jaunce) in Gang Busters (1942) and Guns Don't Argue (serialized in 1952, and released as a feature film in 1957); Jean Willes in The FBI Story (1959); Cloris Leachman in Dillinger (1973); Bernadette Peters (as Nellie) in Love, American Style; Louise Fletcher in The Lady in Red (1979); Debi Monahan in Dillinger and Capone (1995); and Branka Katić in Public Enemies (2009).

[16] In Romania, interest in the career of Ana Cumpănaș was sparked by Mircea Veroiu's film Femeia în roșu ("The Woman in Red", 1997).

[18] A best seller, the novel reportedly propelled Cumpănaș the character to iconic status in Romania, and, according to critic Cornel Ungureanu, made her "the actual aunt of autochthonous Postmodernism.

[6][19] Nash, whose version of events is deemed "quaint" by crime historian Jonathan Goodman,[19] further argues that her deportation was part of a cover-up.
