Charles Milles Manson (né Maddox, November 12, 1934 – November 19, 2017) was an American criminal and cult leader. In the late 1960s, he formed what became known as the Manson Family, a quasi-commune in California. Manson's followers committed a series of nine murders at four locations in July and August 1969. In 1971, he was convicted of first-degree murder and conspiracy to commit murder for the deaths of seven people, all of which members of the group carried out at his instruction. Manson was also convicted of first-degree murder for two other deaths.
