They were all quickly let go due to a misdated warrant, but a few months later, on December 1, 1969, Tex Watson and Patricia Krenwinkel were arrested as suspects in the Tate murders (Charles Manson and Susan Atkins were already in custody), and Linda Kasabian turned herself in a day later.
The crime scene was discovered the next day by a housekeeper, and the LAPD arrested Charles Manson and 25 others on August 16 during a raid on Spahn Ranch.
Kasabian was ultimately given immunity for her role as a key witness, and on January 25, 1971, after a lengthy trial, Watson, Krenwinkel, and Atkins were convicted on all 27 counts against them.
