Manson didn’t kill Hinman, it was Bobby Beausoleil who stabbed Hinman to death.
I was wrong on the name, but I do remember reading in Helter Skelter that the biker guy that helped Bugleosi (sp?) build a case against Manson said that Charlie had killed a Black Panther guy and some other guys at Spawn ranch.
I don’t think Manson is completely guiltless of murder. He’s got blood on his hands personally.
