Mary Kennedy Dead: RFK Jr. Estranged Wife, Found Dead

UPDATE: Mary Richardson Kennedy, the wife of Robert F. Kennedy Jr., died of asphyxiation by hanging, reports New York's Westchester County Medical Examiner's office.    

Mary Richardson Kennedy, the estranged wife of environmental lawyer Robert F. Kennedy Jr., was found dead Wednesday at her husband's home in Bedford, N.Y. 

Though unconfirmed sources had cited suicide, the Bedford Police Department and Westchester County Medical Examiner's Office are still investigating the "unattended death" and are yet to make a pronouncement.  

Kennedy was 52 and is outlived by her husband RFK Jr. (Jack Kennedy's nephew, Bobby Kennedy's son) and four children. The couple filed for divorce two years ago, in an event that resulted in a 911 call after which the police found the couple in an argument with Mr. Kennedy claiming his wife was "intoxicated." 

Two days later, Mary Kennedy was indeed arrested for driving while intoxicated. 

The Kennedy family has released an official statement to the New York Times:

"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."
