The money was pilfered from accounts of his stepson Robbie, the bank loan officer, who s missing. Late that night, Robbie returns to the Manson family mansion, just as Manson (Michael Rennie, The Day the Earth Stood Still) is fleeing with a packed suitcase. Robbie holds a bag too, filled with documents from out-of-town which prove Manson stole the money. When Robbie refuses to let him get away, Manson clamps his hand over Robbie s mouth, begging him to listen. Robbie suffocates, so Manson doctors the crime scene to look like a suicide by hanging.
