David Joseph Carpenter (born May 6, 1930), a.k.a. The Trailside Killer, is an American serial killer and serial rapist known for stalking and murdering a variety of individuals on hiking trails in state parks near San Francisco, California. He attacked at least ten individuals, with two attempted victims, Steven Haertle and Lois Rinna (mother of television personality Lisa Rinna) surviving. Carpenter shot a .38 caliber handgun in all but one of the killings with a .44 caliber handgun used in the killing of Edda Kane on Mount Tamalpais. Early life David Carpenter, a native of San Francisco, was physically abused as a child by his alcoholic father and domineering mother. As a boy he had a severe stutter, a persistent bed-wetting problem and exhibited cruelty to animals. At age 13, Carpenter was incarcerated for molesting two of his cousins. Crimes Carpenter’s first attempted murder occurred in 1960, for which he spent seven years in prison. This was committed against Lois Rinna, mother of future television personality Lisa Rinna. He was arrested for kidnapping in 1970 and spent another seven years behind bars. After his release, Carpenter became a suspect in the Zodiac murders but he was eventually cleared. From 1979 to 1981, Carpenter raped and murdered five women in Santa Cruz County and Marin County. On May 10, 1988, a San Diego jury convicted him on five counts of first-degree murder in the deaths of Richard Stowers, Cynthia Moreland, Shauna May, Diane O'Connell, and Anne Alderson. He also was found guilty of raping two of the women and attempting to rape a third. Carpenter was sentenced to die in the gas chamber and remains on death row in San Quentin State Prison. Following his conviction for the Marin County murders, Carpenter was tried and subsequently convicted by a Santa Cruz jury for the murders of Ellen Hansen and Heather Scaggs. The same jury also found him guilty of the attempted murder of Hansen's hiking companion, Steven Haertle, the attempted rape of Hansen and the rape of Scaggs. Hansen, who was a University of California-Davis student, has a memorial scholarship created in honor of her courage during the attack, which allowed Haertle to escape alive. In 1995, the Santa Cruz convictions were overturned due to juror misconduct. The California Supreme Court later reinstated the Santa Cruz convictions. In December 2009, the San Francisco Police Department reexamined evidence from the October 21,
