@roamer_1 Don't do an autopsy sure to find he died from a substance injected into his body - don't look for a needle puncture, say, between his toes which may be where the needle was inserted. After death, he was hung up with whatever that was, to indicate he hanged himself. If there was a camera going, it was turned off for a brief time long enough to inject him, turned back on and when he was dead, turn it off a brief time to hang his body, then turn it back on.
