Charles Milles Manson (born November 12, 1934) is an American criminal and musician who led what became known as the Manson Family, a quasi-commune that arose in the California desert, in the late-1960s. 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 his fellow conspirators commit in furtherance of the conspiracy's objective
