The Pinkerton Detective Agency described her, in 1906, as having, "classic good looks, 27 or 28 years old, 5'4" to 5'5" [163–165 cm] in height, weighing between 110 and 115 lb [50 and 52 kg], with a medium build and brown hair."

[1] Another conjecture is that she was a cattle rustler named Ann Bassett (1878–1956), who knew and ran with the Wild Bunch at the turn of the 20th century.

Both Bassett and Place were attractive women, with similar facial features, body frame, and hair color.

Bassett was arrested and briefly incarcerated in Utah for rustling cattle in 1903, while Place was in South America with Longabaugh and Parker.

[4] A once-popular theory held that she was Eunice Gray, who for many years operated a brothel in Fort Worth, and later ran the Waco Hotel there until she died in a fire in January 1962.

[citation needed] In 1909, a woman matching Place's description asked Frank Aller (US vice consul in Antofagasta, Chile) for assistance in obtaining a death certificate for Longabaugh.

[6] Author Richard Llewellyn claimed that while in Argentina, he found indications that Place had moved to Paraguay following the death of Longabaugh, and that she had married a wealthy man.

[citation needed] A Pinkerton report states that a woman matching Place's description was killed in a shootout resulting from a domestic dispute with a man named Mateo Gebhart in Chubut, Argentina, in March 1922.

[citation needed] Researcher Larry Pointer, author of the 1977 book In Search of Butch Cassidy, wrote that Place's identity and fate are "one of the most intriguing riddles in western history.
