Hi Patti, This is sad news. I remember him so well as Eliot Ness on the "Untouchables," and mostly for his "Unsolved Mysteries" show, which I love and use to watch faithfully. I understand that his wife had found him slumped over a chair and that his heart gave away on him.
The saddest part is that he just got over a bout with cancer (I think Prostrate) and had beaten it, only to die from a heart attack. I always thought he was such a handsome looking man. May he rest in peace now.
