He attacked at least ten individuals and was convicted in seven murders and was confirmed to be the killer in an eighth murder; Carpenter is also suspected in two additional killings. Two victims, Steven Haertle and Lois Rinna, mother of television personality Lisa Rinna, survived. Carpenter used a .38 caliber handgun in all but one of the killings. A .44 caliber handgun was used in the killing of Edda Kane on Mount Tamalpais.

Angelo Anthony Buono Jr. (October 5, 1934 – September 21, 2002) was an American serial killer, kidnapper and rapist who, together with his adopted cousin Kenneth Bianchi, were known as the Hillside Stranglers. Buono and Bianchi were convicted of killing ten young women in Los Angeles, California, between October 1977 and February 1978.

Lawrencia Ann "Bambi" Bembenek (August 15, 1958 – November 20, 2010), known as Laurie Bembenek, was an American former police officer, convicted for the 1981 murder of her husband's ex-wife. Her story garnered national attention in 1990 after Bembenek escaped from Taycheedah Correctional Institution in Wisconsin and was recaptured in Thunder Bay, Ontario, an episode that inspired books, movies and the slogan "Run, Bambi, Run". Upon winning a new trial, Bembenek pleaded no contest to second-degree murder and was sentenced to time served and 10 years' probation in December 1992. For years, she sought to have the sentence overturned.Prior to her arrest, Bembenek was fired by the Milwaukee Police Department and subsequently sued the department, claiming that its officers engaged in sexual discrimination and other illegal activities. She worked briefly as a waitress at the Lake Geneva, Wisconsin, Playboy Club. At the time of her arrest, she was working for Marquette University's Public Safety Department in downtown Milwaukee. On November 20, 2010, Bembenek died at a hospice facility in Portland, Oregon at age 52.
