Charles Milles Manson was an American criminal and cult leader. In mid-1967, he formed what became known as the "Manson Family", a quasi-commune based in California. Manson's followers committed a series of nine murders at four locations in July and August 1969. According to the Los Angeles County district attorney, Manson plotted to start a race war, though he and others involved long disputed this motive. In 1971, he was convicted of first-degree murder and conspiracy to commit murder for the deaths of seven people. Although the prosecution conceded that Manson never literally ordered the murders, they contended that his ideology constituted an overt act of conspiracy. Manson was also convicted of first-degree murder for the deaths of Gary Hinman and Donald Shea.
