On October 19, 1971, a Los Angeles Superior Court judge formally sentenced Charles Manson and three of his followers to death for their roles in the 1969 murders of actress Sharon Tate and others, and in the subsequent LaBianca killings. The sentence followed a widely covered trial that had begun in 1970 and resulted in multiple convictions for murder and conspiracy to commit murder. Background In August 1969, members of what prosecutors called the “Manson Family,” a loosely organized group led by Charles Manson, carried out a series of brutal killings in Los Angeles. On August 8–9, 1969, five people, including actress Sharon Tate and several guests, were murdered at Tate’s home. The next night, Leno and Rosemary LaBianca were killed in their home in Los Feliz. Prosecutors asserted that Manson directed followers to commit the murders as part of a plan to ignite a race war he termed “Helter Skelter.” The Trial The trial of Manson and several of his followers began in July 1970 and became one of the most closely watched criminal cases in American history. Defendants included Charles Manson and key associates such as Susan Atkins, Patricia Krenwinkel and Leslie Van Houten. The proceedings were marked by the defendants’ disruptive courtroom behavior, Manson’s cryptic outbursts, extensive media coverage and testimony from prosecution witnesses linking the defendants to the crime scenes and to Manson’s alleged instructions. Conviction and Sentencing In 1971 jurors convicted Manson and several co-defendants of first-degree murder and conspiracy to commit murder. On October 19, 1971, the judge imposed the death penalty on Manson and three of his followers. The sentence reflected the statutory capital punishment regime in California at the time, which allowed death by gas chamber for certain aggravated murders. Aftermath The death sentences did not remain in effect. In 1972, the California Supreme Court’s decision in People v. Anderson invalidated the state’s death penalty statute, and Governor Ronald Reagan subsequently signed legislation that briefly abolished capital punishment in the state. As a result, the capital sentences against Manson and others were automatically commuted to life imprisonment with the possibility of parole removed or restricted by later proceedings and legislation. Charles Manson remained incarcerated until his death in 2017. Historical significance The Manson trial and sentencing had a lasting cultural and legal impact. The case crystallized public fears about violent cults and countercultural excesses at the end of the 1960s, influenced debates about the death penalty in California, and led to continuing public fascination and extensive media coverage of Manson, his followers and the crimes. The legal developments that followed—particularly the 1972 court ruling—changed the immediate legal consequences for Manson and others, converting death sentences into life terms.
