Editing Charles Whitman (section)

===Prelude===
The day before the shootings, Whitman bought a pair of binoculars and a knife from a hardware store, and some Spam from a 7-Eleven convenience store. He picked up his wife from her summer job as a telephone operator before he met his mother for lunch at the Wyatt Cafeteria, which was close to the university.

At about 4:00 p.m. on July 31, 1966, Charles and Kathy Whitman visited their close friends John and Fran Morgan. They left the Morgans' apartment at 5:50 p.m. so Kathy could get to her 6:00–10:00 p.m. shift.

Shortly afterwards, Whitman wrote a suicide note. In his note, he went on to request an autopsy be performed on his remains after he was dead to determine if there had been a discernible biological contributory cause for his actions and for his continuing and increasingly intense headaches. He also wrote that he had decided to kill both his mother and wife. Expressing uncertainty about his reasons, he nonetheless stated he did not believe his mother had "ever enjoyed life as she is entitled to", and that his wife had "been as fine a wife to me as any man could ever hope to have". Whitman further explained that he wanted to relieve both his wife and mother of the suffering of this world, and to save them the embarrassment of his actions. He did not mention planning the attack at the university.
