- How he joined the cult: In the late '60s, Tex met some of the women of the Manson family before meeting with Manson himself. He decided to join the cult shortly after and was often regarded as Manson's right-hand man.
- Which crimes he committed: On Aug. 9, 1969, Tex accompanied a few other family members to Sharon Tate's home. When an 18‑year‑old named Steven Parent arrived from the guest house, Tex shot him four times in the chest and abdomen. Inside, Tex tied up Sharon Tate and hairdresser Jay Sebring at the neck with a rope. When Jay resisted, Tex shot him. The next night, on August 10, Tex showed up at Leno and Rosemary LaBianca's home with Leslie Van Houten and Patricia Krenwinkel. While Leslie and Patricia murdered Rosemary in the bedroom, Tex murdered Leno in the den.
- What his sentence was: On Oct. 2, 1969, Tex left the Spahn Ranch and headed back to his native Texas, where he was ultimately arrested almost a month later on Nov. 30. On Oct. 12, 1971, Tex was convicted of seven counts of first-degree murder and one count of conspiracy to commit murder. On October 21, he was sentenced to death, but that sentence was later altered to life in prison following California Supreme Court's People v. Anderson. While in jail, Tex married a woman named Kristin Joan Svege. They eventually had four kids together through their conjugal visits. After 24 years of marriage, they divorced in 2003. Tex remains in prison to this day.
