In 1950, Hill married Hans Hauser, an Austrian skier (and head of the Sun Valley, Idaho Ski School); later giving birth to their only child, Peter Hauser (November 20, 1950 – 1994). In 1951, Hill was subpoenaed to testify before the Kefauver hearings, where she denied having any knowledge of organized crime despite being described by "Time" magazine in March of that year as the "queen of the gangsters' molls." After Hill was indicted for income tax evasion in 1954, she moved to Europe, where she lived for the rest of her life with her son.
