An autopsy revealed Mary Kennedy’s cause of death was asphyxiation as a result of hanging, medical examiners said Thursday. Kennedy, the estranged wife of Robert Kennedy Jr., was found dead Wednesday in her Bedford, N.Y., estate. Bedford police said they discovered Kennedy’s body inside an “outbuilding on the property.” Kennedy was the mother of four children, ages 10 to 17, and reportedly battled drug and alcohol problems in recent years.
