"He blamed his mother for chewing her food too loudly and his sister’s bad accent as part of a plan to drive him mad."

Said the teenager, who killed his parents and sister 46 years ago. He spent 6 years in a mental institution, then changed his last name, studied psychology, and became a professor.

The pony-tailed professor, Dr. James St. James — the head of Millikin University’s psychology department — was outed by a Texas reporter with the Georgetown Advocate, a newspaper based in the town where St. James fatally shot his parents and 17-year-old sister on Aug. 4, 1967.

One student said: "He really is a good guy. I have really fond memories, and I feel sorry for him, because now his life is all turned upside down."
