Another tragedy for the Kennedy clan -
Robert F Kennedy Jr's estranged wife has been found dead at her home in New York state.
No cause of death had been released, but US media reported the 52-year-old had been discovered hanged.
In a statement, the family of the 52-year-old said her "radiant and creative spirit" would be sorely missed.
Mr Kennedy, a lawyer and radio host, is the nephew of President John F Kennedy and son of Senator Robert F Kennedy, both assassinated in the 1960s.
His marriage to the former Mary Richardson in 1994, in a ceremony aboard a boat on the Hudson river, was his second.
The couple had four children over the 16 years of their marriage before he filed for divorce in 2010.
