For those who are not familiar with the case:
Manson and his followers committed a series of nine murders at four locations in California, over a period of five weeks in the summer of 1969. Atkins, known within the Manson family as "Sadie Mae Glutz," was convicted for her participation in eight of these killings, including the most notorious, the "Sharon Tate/LaBianca" murders.
Five people were murdered at the Beverly Hills home belonging to Roman Polanski and Sharon Tate: Tate (who was eight months pregnant), Steven Parent, Jay Sebring, Wojciech Frykowski, and coffee heiress Abigail Folger. Polanski, Tate's husband, was in Europe finishing work on a film project.
Forensic evidence indicated that the murders were brutal. Just prior to leaving the residence, Atkins wrote "Pig" on the front door in Sharon Tate's blood. [4]
While in jail, Atkins befriended two middle-aged career criminals, Virginia Graham and Veronica "Ronnie" Howard, to whom she confessed her participation in the Tate/LaBianca murders, for example telling the women that she stabbed Tate and that she had tasted Tate's blood. They subsequently reported her statements to the authorities. [11] This, combined with information from other sources, led to the arrest of Atkins and others involved in the Tate/LaBianca murders (Van Houten, Krenwinkel, Kasabian and Watson).
Atkins agreed to testify for the prosecution in exchange for the prosecution not seeking the death penalty, and she then testified before the grand jury as to what had transpired on the nights of August 8 and 9, 1969. [12] .
Atkins told the grand jury that she stabbed Frykowski in the legs and that she held Tate down while Watson stabbed her. She also testified that Tate had pleaded for her life and that of her unborn child, to which Atkins replied, "Woman, I have no mercy for you." She also denied her earlier statement to Howard and Graham that she had tasted Tate's blood. [citation needed] Prior to the trial, Atkins discontinued her cooperation with the prosecution and repudiated her grand jury testimony, although years later she would state that this testimony was truthful and accurate as to what transpired in the Tate home. [citation needed]
Atkins has claimed over the years that her participation in the crimes led by Manson was passive and that she didn't actually kill anyone. However, in her grand jury testimony she admits to active participation in the crimes.
