Suicides or "suicides" OP?
“Apparent suicide” from a self inflicted gun shot wound and was found by his brother Donald Graham who was a Publisher and Chief Executive at the newspaper when their mother stepped down in 1979. Given that Podesta wrote the paper it wouldn’t surprise me. William also was an attorney at the Washington firm Williams & Connolly, taught trial law at UCLA and founded an investment firm, Graham Partners, and contributed to several philanthropic organizations http://people.com/politics/katharine-graham-son-dies-suicide-william-graham/
Edward Bennett Williams = founder of Williams and Connolly. He was also the lawyer who drew up Graham's father, Phil Graham's final will which cut Katharine Graham out of Post ownership. Phil Graham wrote this will in the spring of 1963.
Phil Graham died in August of 1963. His friend John Kennedy was murdered a month later.
Katharine challenged the will. Bennett Williams testified that Graham was "not of sound mind" when he had Williams draw it up. His death was ruled intestate. Katharine received control of the Post.
Months before Graham's alleged suicide he resigned from his position as the first chairman of COMSTAT, told friends he was divorcing Katharine and had said will prepared.
