I found out a little more, which is still bad, but in a different way. The background is that she was assaulted over the weekend, but was at her home on Sunday. Her family found her body Monday. Autopsy results showed painkillers in her system, but they had been prescribed for her; what was in her bloodstream was a higher dose than had been prescribed, but not super high. So it may have been an accidental overdose, which is a whole other kind of horrible. It also might have been intentional, but there was no note or anything, so it's not conclusive.
The family wants a private service and burial, so our friends will have a memorial service later.
I'm glad she wasn't murdered, but...damn. My heart hurts. (Not like Lang heart attack pain. Metaphorically.)
