Charles Milles Manson was an American criminal, cult leader, and songwriter. 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 were carried out at his instruction by members of the group. Manson was also convicted of first-degree murder for two other deaths.
