Leslie Louise Van Houten is an American convicted murderer and former member of the Manson Family. During her time with Manson's group, she was known by aliases such as Louella Alexandria, Leslie Marie Sankston, Linda Sue Owens and Lulu.

The Manson Family was a commune, gang, and cult led by criminal Charles Manson that was active in California in the late 1960s and early 1970s. The group at its peak consisted of approximately 100 followers, who lived an unconventional lifestyle, frequently using psychoactive drugs, including amphetamine and hallucinogens such as LSD. Most were young women from middle-class backgrounds, many of whom were attracted by hippie culture and communal living and then radicalized by Manson's teachings. The group is confirmed to have murdered 9 people, though they potentially killed up to 24.
