Gandolfini 'died of heart attack'
A post mortem has found that actor James Gandolfini died of a heart attack, with no evidence of substance abuse or foul play, a family friend said.
James Gandolfini, whose portrayal of a brutal, emotionally delicate mob boss in HBO's The Sopranos helped create one of TV's greatest drama series and turned the mobster stereotype on its head, died Wednesday in Italy.
