In March 1963, Oswald used the alias "A. Hidell" to make a mail-order purchase of a secondhand
6.5 mm caliber Carcano rifle for $29.95.
[78] He also purchased a .38
Smith & Wesson Model 10 revolver by the same method.
[79] On April 10, 1963, Oswald attempted to kill retired U.S. Major General
Edwin Walker. He fired the Carcano rifle at Walker through a window from less than 100 feet (30 m) away as Walker sat at a desk in his Dallas home. The bullet struck the window-frame and Walker's only injuries were bullet fragments to the forearm.
[80] The
United States House Select Committee on Assassinations stated that the "evidence strongly suggested" that Oswald carried out the shooting.
