Patricia Krenwinkel, aka "Katie," played a key part in the infamous Tate-LaBianca murders spearheaded by Charles Manson in 1969. She stabbed Abigail Folger so many times, police thought the coffee heiress' originally white nightgown was bought red when they found her body. She also stabbed Rosemary LaBianca, and wrote "DEATH TO PIGS" on a wall on the LaBiancas' house and "HeaLter SkeLTter" on the LaBiancas' refrigerator. During her murder trial, she doodled Satanic images and, along with her fellow Manson devotees, added to the spectacle by shaving her head and carving an X into her forehead.
