Not much is known about Kemper’s fiancee, as she has never gone public with her story. After Kemper’s arrest, she was apparently very much in shock, and went into seclusion. Her parents sent her away from Turlock. Officials at her high school, where she was in her senior year, consented to excuse her from classes until the emotional pressure on her let up, and allowed her to graduate with her class.

Police said a newspaper clipping reporting the engagement was found with Kemper’s belongings in the Aptos apartment where he lived with his mother. In his bedroom, they also found the picture of a beautiful blonde said to be a fiancee of Kemper.

We know that she had met Kemper at a Santa Cruz beach in the summer of 1972. Her age varies according to reports between 16, 17 or 18 years old. Her first name might have been Martha, but this is unverified information from a social media source.
