The family set up residence in Dallas, Texas, with Oswald taking on the post-office alias of Alek J. Hidell. Around this time, Oswald's interest in communism tranformed into support for Cuba. In early 1963, he ordered a .38 handgun via the mail and later acquired a rifle. He had Marina take a picture of him with the weapons—a document that would later be used as criminal evidence, as Oswald's rifle was eventually identified as the firearm used to murder President John F. Kennedy.
