My personal theory is that someone might have accidentally logged on after the funeral if they were going through her belongings. My family did something similar when my grandpa died.
lionsden121 I was thinking they might have looked at their history out of curiosity and either accidentally opened it or opened it to see what it was. Admittedly it's how I found out said grandpa's porn preferences :|
I just don’t think my family would get into my computer and like open all my websites and go through all my stuff (non bank/credit card related). I sorta find that weird but idk
They might not have even logged on, maybe she always kept the tab open and logged in on her desktop and someone moved the mouse while cleaning up her things.
