Me too. I'd call 911. Wondering if she may have some early scattered episodes of oncoming dementia. I was caretaker for my dad for a time until his became pretty unmanageable for one person 24/7. It also was said here the house was up for sale in the past year or two. Maybe family has concerns not made public. MOOWhat still strikes me as completely implausible is an 84 yo woman answering her front door after 1:30 a.m. Even if the suspect was banging on it - even more reason not to answer it. I would imagine if the noise woke her up, she would be frightened and check her phone.
~moo~
We just don't know how a person or persons entered the house. I know we likely don't even know 10% of what's going on in this case or what LE has. Everything is just guessing at this point.
Again only MOO
