Edit: I am going to share a bit more about what I managed to find out, as I know there is a lot of speculation. It has been learned from the woman who found her (a personal friend who regularly took her shopping, etc) that Alicia was found dead in her home, near her computer, a wound on the back of her head. The theory is that she went to sit on her chair, it rolled away from her, and she fell backwards, hitting her head on the floor and expiring.
Honestly, I have my doubts if that is the full story. But, sadly, there is no way for me to get any more information. So, for now, her death is being characterized as a tragic accident. Regardless
