Carpenter's first attempted murder occurred in 1960, for which he spent seven years in prison. This was committed against Lois Rinna, the mother of future television personality Lisa Rinna.[8] 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, although he was eventually cleared.[7]

From 1979 to 1981, Carpenter raped and killed 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 was found guilty of raping two of the women and attempting to rape a third.[9] Carpenter was sentenced to die in the gas chamber and remained on death row in San Quentin State Prison[10] for over forty years until, in March 2019, his sentence was reduced to life without parole, due to a moratorium on executions in California. He was subsequently moved off of death row and is incarcerated in the California Health Care Facility (CHCF) as of 2025.[11]

Following his conviction for the Marin County murders, Carpenter was tried and convicted by a Santa Cruz jury for the murder and attempted rape of Ellen Hansen, the rape and murder of Heather Scaggs, and the attempted murder of Hansen's hiking companion, Steven Haertle.[12] Hansen, who was a University of California-Davis student, has a memorial scholarship dedicated to her in honor of her courage during the attack, which allowed Haertle to escape alive.[13] In 1995, the Santa Cruz convictions were overturned due to juror misconduct. The California Supreme Court later reinstated the Santa Cruz convictions.[14]

In December 2009, the San Francisco Police Department reexamined evidence from the October 21, 1979 murder of Mary Frances Bennett, who was jogging at Lands End when she was attacked and stabbed to death. A DNA sample obtained from the evidence was matched to Carpenter through state Department of Justice files. In February 2010, police confirmed the match with a recently obtained sample from Carpenter.[15] Carpenter is still a suspect in the murders of Edda Kane and Barbara Schwartz.[16]

The Trailside killings provide the context for Joyce Maynard's 2013 novel After Her.[17] On television, both The New Detectives and Born to Kill? made an episode about the case: "Body Count" and "David Carpenter: The Trailside Killer", respectively.[citation needed] In 2023, he was featured on a two-part episode of “Very Scary People”.
