Conrad.....possible spoiler.
It seems to me that Conrad appears too young to be Manson's son. He only appeared to be between 35-42ish, which would put his birth year between 1973-1980....after Manson had been sentenced to life in prison.
All of the children born to Manson girls during their heyday, are in their late 40s now, and the older ones are knocking on 50.
