In high school, Schaefer had dated Sondra London, who later became a true crime writer. She got in touch with Schaefer following his conviction and in 1989 she published Killer Fiction, short stories and drawings found in Schaefer's house after his arrest. A follow-up, Beyond Killer Fiction, was later released. Following his death, London released another edition of Killer Fiction, containing the stories and rambling articles by Schaefer that were in the previous two books, together with Schaefer's letters to her where he boasted of killing 34 women and girls and how he was admired by fellow inmate Ted Bundy. At the same time Schaefer had been writing these boastful claims, he was appealing his conviction and trying to sue anyone who dared to call him a serial killer.
The short stories Schaefer wrote all featured the savage torture and murder of women. They were often written from the killer's perspective, the killer often a rogue cop — just like Schaefer.
In his writings, Schaefer claimed to have started murdering women as early as 1965, when he was 19.
Two schoolgirls, nine-year-old Peggy Rahn and eight-year-old Wendy Stevenson, vanished in December 29, 1969 after being seen in the company of a man fitting Schaefer's description. Schaefer denied being involved when he was publicly accused of the crime, but in a letter to London in 1989 he boasted of killing and cannibalizing the two children.
London and Schaefer had briefly been engaged in 1991, but London broke it off and got engaged (to another serial killer from Florida, Danny Rolling). Schaefer did not take the rejection well, and began sending her death threats. He tried three times to sue her for "stealing" his work.
