I remember the Brenda Spencer story pretty well. I grew up in that area.
Just a few years earlier, and just a couple of miles away, a high school senior, Danny Alstadt took an axe, and gave his father 40 whacks. And when he saw what he had done, he did the same to his mother and sister. His younger brother survived, but last I heard was still paralyzed. Danny hung himself in prison about 10 years ago. He had been my younger brother’s science lab partner in high school.
