Jesperson reported that he was raped at the age of 14. He graduated from high school in 1973, but did not attend college because his father did not believe he could do it. Although he was not successful with girls in high school, having never even attended a school dance or his prom, he did enter into a relationship after high school. In 1975, when Jesperson was 20, he married Rose Hucke, and the couple had three children—two daughters and one son. Jesperson worked as a truck driver to support the family.
