Esteemed college professor, 61, revealed to be teen killer who murdered his family in 1967

I remember watching a show about the same kind of incident. A man killed his parents at 14-16 and was released at 18. He moved away from where he grew up and married(he told his wife his parents died in an accident I think). He then formed an obsession over his niece and ended up killing her, his wife and himself. History often repeats itself.

ETA: his name was Carl Brandt
