Thinking of Audrey in terms of victimology, a couple of things come to mind as it relates to whether or not she knew her attacker:
- she was not in sleep attire, so presumably she was not awakened by an intruder
- had she suspected an intruder, I'm sure she would have let her dogs loose
- she seemed to be aware of a potential danger to her as expressed by her "raped and murdered" comment and her expressed fear of going outside alone at night without her dogs
IMO, because Audrey already had her guard up wrt possible dangers, and was more than likely awake and alert when her killer attacked, and her guard dogs were confined elsewhere ... she was not blitz attacked by a stranger, but more than likely conned by someone known to her.
FWIW, I'm not convinced that Audrey was really that much of a "nighthawk". Her usual weekly coffee at LV's (as recently as Dec 26th) was said to be 9:30 am; her first email to PK on the 27th was there whenever he first opened his email that morning; her second email to PK was timed 10:46 am. Although older people typically get less sleep, I doubt that she stayed up
that late if she was able to be up and about, getting herself together and sending emails and visiting at a reasonable time of the morning. IOW, I'm not convinced that Audrey was killed at night, but possibly during the daytime when she would have been less suspicious of a visitor.
Okay ... I think I'm rambling here
