Mary Kennedy, the estranged wife of Robert F. Kennedy Jr., died of "asphyxiation due to hanging," according to the results of an autopsy performed on Thursday.
Mary Kennedy was found dead in her Bedford, N.Y., home on Wednesday. The 52-year-old designer had struggled with alcohol and drug problems.
In 1994, the former Mary Richardson married Robert F. Kennedy Jr., an environmental lawyer and son of the late Sen. Robert F. Kennedy. The couple had four children together. Robert F. Kennedy Jr. filed for divorce in May 2010.
On Wednesday, a spokesperson for Mary Kennedy's family released a statement, saying, "We deeply regret the death of our beloved sister Mary, whose radiant and creative spirit will be sorely missed by those who loved her. Our heart goes out to her children who she loved without reservation. We have no further comment at this time."
