will never be known. While incarcerated, he frequently encouraged speculation as to how many victims he had claimed, while simultaneously denying he had ever committed murder and claiming the numerous writings discovered at his mother's residence were purely fictional. Author Patrick Kendrick believes the most likely year Schaefer began killing is 1969, and that his true victim count stands at around eleven, although the commonly held belief is that he may have claimed up to twenty-eight victims. The initial list of twenty-eight potential victims was first published in a Florida periodical in the spring of 1973, although this list—which also includes seven males whose personal artifacts were recovered from his mother's home—contains the names of several individuals later discovered to have still been alive at the time of his arrest, or to have died at a later date. For example, one of the young women on this compiled list, 14-year-old Katrina Marie Bivens (reported missing in January 1970) was located alive in June of the same year, whereas one of the males upon the list, Michael Angeline, died in a plane crash in 1981. 1966 October 2: Nancy Elaine Leichner (21) and Pamela Ann Nater (20). Last seen alive hiking in the Alexander Springs Wilderness recreation area of the Ocala National Forest. Although authorities initially believed the two had drowned while swimming, this theory was ultimately disproven. Schaefer later confessed to their murders. 1969 September 8: Leigh Farrell Hainline Bonadies (24). A newlywed waitress who had known Schaefer since both were teenagers. She is last known to have left a note to her husband of two weeks indicating she intended to drive to Miami but would return home that evening. Schaefer later claimed to a private investigator that Bonadies had phoned him on the date of her disappearance asking for a ride to Miami International Airport but had never called him back. Her skull, bearing three bullet holes, was discovered at a construction site in Palm Beach County in April 1978. December 18: Carmen Marie Hallock (22). Hallock disappeared after informing her sister she had an appointment with a male teacher from Broward Community College who may be able to provide her with "a government job". She was last seen wearing a black chiffon dress; one of the stories Schaefer is known to have penned prior to his arrest recounts the hanging and mutilation of a girl with auburn hair
