Charles Milles Manson is an American criminal who led what became known as the Manson Family, a quasi-commune that arose in the California desert in the late 1960s. Manson and his followers committed a series of nine murders at four locations over a period of five weeks in the summer of 1969. In 1971 he was found guilty of conspiracy to commit the murders of seven people: actress Sharon Tate and four other people at Tate's home; and the next day, a married couple, Leno and Rosemary LaBianca; all carried out by members of the group at his instruction. He was convicted of the murders through the joint-responsibility rule, which makes each member of a conspiracy guilty of crimes committed by fellow conspirators in furtherance of the conspiracy's objective. His followers also murdered several other people at other times and locations, and Manson was also convicted for two of these other murders.
