I don't understand why the makers ignored the testimony of a close relative (aunt) of the killer. She goes in detail about how she noticed once that his own grandmother most likeliy terrorized and sexually abused him from an early age. They were living together for a long time. Then, later on, as a nurse, he probably killed the grandmother, too. Is it not strange to ignore these events - even if they are just possibilities - as a forensic psychiatrist, as a detective and a prosecutor...? Which does not mean they should not sentence him - but they could have given this information to the victims' families. This is a very serious childhood trauma of captivity and abuse at your home, which can absolutely result in being a serial killer. Why ignore it like this?
