Warren Commission Testimony
Testimony from FBI files of JFK assassination
Here in the testimony you can see that Chief Curry told the "Dallas Times Herald" that Lee Harvey Oswald's transfer would be placed in the custody of Sheriff J.E. Bill Decker on November 24, 1963. He also was reported that he revealed the time of the transfer saying "You better be around here about 10:00 AM", thus revealing to the press what time JFK's killer was being moved. He did not know at the time what this information would lead to and it is still debated whether or not he actually said the time to the press.
November 20, 1963
