What Happened to General Walker?

General Walker called for the US to liquidate the communist scourge that has descended upon Cuba. Lee Harvey Oswald ordered a man-licker Carcano rifle by mail order using the false name A Heidel seven days after General Walker's speech in March 1963. At 9 p.m. on the evening of April 10, General Walker was sitting in the back of his house, preparing his taxes and suddenly a shot rang out. The Dallas police investigated this shooting but didn't find the person or persons responsible.
