Mary Kennedy, the estranged wife of Robert F. Kennedy, Jr., was found dead from an apparent suicide in her home in Mount Kisco, New York. She was 52. An official with Westchester County in New York confirmed the death of the 52-year-old after an ambulance was outside the separated couple’s home earlier in the day. RFK Jr., the son of former Senator Robert Kennedy and nephew of President John F. Kennedy, filed for divorce in 2010 after 16 years of marriage, though the divorce was never finalized. Mary was arrested for drunk driving three days after her husband filed for divorce. Sources close to Kennedy said she was depressed about the split, and others told ABC News that she hanged herself.
