IMO, AG marched to her own drum. Perhaps she had changed her will and advised LV of that.
"In 2007, Audrey decided it was time to write her will and made Lynne executor."

JMHO, but there's a possibility that LV did voice her discernment about AG's actions to JV. LE stated that there were items missing from AG's house. Maybe those items happened to include a new signed will...or codicil. Perhaps this is why they didn't spend Christmas together?

IMO, PK, as a person AG did invite into her home, was probably the person who was able to identify to LE what was missing. PK may not have been in her home in the weeks or months prior to her murder, but he may have had a good idea of where things were always displayed or kept, especially in the area where he said they would sit and chat on the sofa.(same source as 1st link above) If LV was only in AG's home once, I doubt she'd be able to identify what was missing. JMHO, but if a person was searching for a document, and didn't know who was aware of it's existence, I could see the perp taking a bunch of things to muddy the waters. If it was never found, then quickly clearing out the house would make a lot of sense. MOO
