Charles Milles Manson is an American convicted mass murderer and former cult leader who led what became known as the Manson Family, a quasi-commune that arose in California in the late 1960s. Manson's followers committed a series of nine murders at four locations in July and August 1969. In 1971 he was found guilty of first-degree murder and conspiracy to commit murder for the deaths of seven people – most notably of the actress Sharon Tate – all of which were carried out by members of the group at his instruction. Manson also received first-degree murder convictions for two other deaths. Manson was originally sentenced to death, but his sentence was commuted to life imprisonment when California invalidated the state's death penalty statute in 1972. He is currently serving multiple life sentences at California State Prison in Corcoran.
