Robert F. Kennedy Jr.’s estranged wife, Mary Kennedy, was found dead in her home on Wednesday in an apparent suicide. 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 it is rumored that she had hanged herself. Medical examiners began an autopsy on Kennedy on Thursday.
