April 6, 1995 - Gagan enlists the aid of his friend, Bill Bayers, a Denver cab driver, to hand-deliver his final written warning to the U. S. Marshal's Service. (See Sidebar Box) Bayers receives the signature of Sharon Hoff at 9:00 a.m. Hoff happens to be the same U. S. Marshal to whom Gagan had delivered his March 27th warning, and he notes that the signatures match. Gagan's note says, "Call 832-4091 NOW!" Gagan is prepared to pinpoint Oklahoma City as the target. Although Gagan emphatically tells them of a plot to blow up a federal building within two weeks and that "if the information is false, charge me accordingly," no call is forthcoming.
