Chris Wallace's brother and Mike Wallace's son, Peter Wallace was killed in Greece…..accidently. He was supposedly hiking by himself and fell off a cliff.
This reddit post says he went missing and Mike Wallace flew to Greece to look for him and found him at bottom of a cliff.
This other link is interesting when you considerer what Peter did for a living. He was a member of the editorial board of the Yale Daily News, and had worked for CBS news. His last published work was an article on William P. Bundy.
William Bundy was C_A under JFK and Johnson.
Hmmmm…..funny DS cover-up business maybe?
