Patricia Dianne Krenwinkel (born December 3, 1947) is an American convicted murderer and former member of the Manson Family. On August 9, 1969, Patricia Krenwinkel, Tex Watson, and Susan Atkins murdered pregnant actress Sharon Tate, Jay Sebring, Wojciech Frykowski, Abigail Folger, and Steven Parent at 10050 Cielo Drive in Benedict Canyon, Los Angeles. During her time with Manson's group, she was known by various aliases such as Big Patty, Yellow, Marnie Reeves and Mary Ann Scott, but to The Family she was most commonly known as Katie. Following the 2009 death of fellow Manson cult member Susan Atkins, and the release of Leslie Van Houten in 2023, Krenwinkel became the longest-incarcerated female inmate in the California penal system. She was recommended to be released on parole in 2025, but the recommendation was rejected by Governor Gavin Newsom.
