No offense intended, but I don't see how a cold-blooded pederast and killer of young girls is dependent on anyone. That's a personality type that likes to have control of other people. They live secret lives and thus hide those aspects of their personality from others, but at their core they are selfish, manipulative, sadistic people.
Someone who has the ability to kidnap young girls, then spend an hour or so sexually assaulting them, fighting them, forcing them to disrobe and redress, then cutting their throats is an independent, fearless, mentally powerful person. A fearful, insecure, dependent, shy person couldn't do all that, then go home to family and work like nothing happened.
JMO, it's all an act, a way to manipulate others into doing the things he's too lazy to do. By his own admission, he was a sex addict who liked having other people work, pay the bills and handle the hard stuff in life so he could spend his time indulging his sick private life.
ETA: We've heard people in court say that Allen's voice sounds like the recording of BG. Has anyone yet come across any kind of recording of his voice? I'd like to hear it. TIA
