Kemper spent five years at Atascadero after he murdered his grandparents in 1964 at the age of 15. He recalled with pride the job he’d held there as head of the psychological testing lab at the age of 19 and working directly under the hospital’s chief psychologist. He said:
“I felt I definitely could have done a lot of good there, helping people return to the streets … I could have fit in there quicker than anybody else…
“After all,” he explained, “I grew up there. That used to be like my home.
“Basically, I was born there, you know. I have a lot of fond memories of the place … And I don’t know anybody else who has,” he added with a rueful laugh.
It was there that he became a member of the Junior Chamber of Commerce. During his trial, he wore his membership pin in his lapel, apparently with pride.
Because of his intelligence and ability, he apparently was a valuable aide in psychological testing and research. “I helped to develop some new tests and some new scales on MMPI… You’ve probably heard of it … the Minnesota Multiphasic Personality Inventory,” he said with a chuckle. “I helped to develop a new scale on that, the ‘Overt Hostility Scale’… How’s that for a…” He groped for a word.
“Ironic?” I suggested.
“Ironic note,” he agreed. “There we go, it was an ironic note that I helped to develop that scale and then look what happened to me when I got back out on the streets.”
