Eugene B. Dinkin

A soldier stationed in 1963 at Metz military base, where he was deciphering and analyzing for NSA messages aired in Western Europe.

He intercepted two messages, in mid-October and on November 2, announcing the assassination of John F. Kennedy. Being unable to communicate outside the base without his superiors' permission, he asked one of his friends on leave to send a letter to Robert Kennedy.

It is not known whether Bobby Kenendy knew about this document, but Dinkin announced JFK's assassination "around November 28, 1963".
