Charles Manson murder trial on each of the 27 separate counts against them. Not far into the trial's penalty phase, the jurors saw, at last, the defense that Manson—in the prosecution's view—had planned to present. Susan Atkins, Patricia Krenwinkel, and Leslie Van Houten testified the murders had been conceived as "copycat" versions of the Hinman murder, for which Atkins now took credit. The killings, they said, were intended to draw suspicion away from Bobby Beausoleil, by resembling the crime for which he had been jailed. This plan had supposedly been the work of, and carried out under the guidance of, not Manson, but someone allegedly in love with Beausoleil—Linda Kasabian. Among the narrative's weak points was the inability of Atkins to explain why, as she was maintaining, she had written "political piggy" at the Hinman house in the first place.
Midway through the penalty phase, Manson shaved his head and trimmed his beard to a fork; he told the press, "I am the Devil, and the Devil always has a bald head." In what the prosecution regarded as belated recognition on their part that imitation of Manson only proved his domination, the female defendants refrained from shaving their heads until the jurors retired to weigh the state's request for the death penalty.
April 19, 1971, Judge Older sentenced the four to death.
On the day the verdicts recommending the death penalty were returned, news came that the badly decomposed body of Ronald Hughes had been found wedged between two boulders in Ventura County. It was rumored, although never proven, that Hughes was murdered by the Family, possibly because he had stood up to Manson and refused to allow Van Houten to take the stand and absolve Manson of the crimes. Though he might have perished in flooding, Family member Sandra Good stated that Hughes was "the first of the retaliation murders."
