20 H 410: "A Western Union man who had been with us since we came down from Andrews Air Force Base came into the [Parkland Hospital] office. A nurse asked him about a report that a Secret Service agent had been killed out on the street. HE SAID THAT IT WAS TRUE. This was one of the immediate rumors which sprang up. It took several days for this particular rumor not to be believed in Dallas itself (FELLOW IN JAGGARS-CHILES-STOVALL who got it from a friend who got it from a POSTMAN* supposed to have been at the death scene that the shot and bleeding SS man was in on the plot to kill the President.)" [emphasis added]
*the 1/22/77 issue of "The Continuing Inquiry" contains an article written by Penn Jones and Gary Shaw re: the "dead" agent incident as reported in a letter sent to Jim Garrison during the Clay Shaw trial:
"A Mr. Robertson, Assistant Director of the Dallas or Fort Worth Secret Service office, confided to [friend of writer who requested anonymity] in 1963 that a plot to kill President Kennedy was planned and he did not want any part of it. On November 22, 1963, my friend was in the office of Mr. Robertson when all phones began to ring, about the time Kennedy was arriving at Carswell Air Force Base [in Fort Worth], Mr. Robertson then said, 'Well, this is it' and left the office. Since that time Mr. Robertson's family of seven children and wife have not seen or heard from him, yet his paychecks continue to be mailed to his home.”
