Is there any other details on Denise Beaudin? Other than an overbite, did she have any injuries, tattoos, did she wear glasses or contacts? Frustrating with so little detailed information. I did read in another article that the electrical cord used to bind the victims in the barrels had come from Denise's place of work, so he had met her by the time he killed those 4 people. Makes me wonder if he was working as an electrician where she worked and that's how they met. I'm guessing if he changed Dawn's name to Lisa, Denise had probably changed her name when they left as well, if she was alive during that time. When he was arrested in CA he mentioned a girlfriend who was a nurse, that also might have referred back to Denise.
An article noted that he had ingratiated himself into the Korean community when he met Jun, sounds like he was good at putting people at ease And when questioned by the arresting officer in CA he referred to himself as a "non person" when he was asked who he was.
