Coroner: Robert F. Kennedy Jr.’s estranged wife Mary died of ‘asphyxiation due to hanging’

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.

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."
