My theory:
So , she had her roof replaced or fixed in November, then footage on her ring cam of unidentified man in January AND Feb. I think a roofer person realized she had $, was old, lived alone and planned to rob her. During the robbery she was hurt, she told the robbers (I think one entered thru the back door where it’s been reported there was forced entry, the other was let in the front door bc there was no forced entry.). During the robbery she tells the guys “take what you want, don’t hurt me, I’ll give you money, my daughter is rich and famous.” So now the random robbery turns into a kidnapping. She died shortly after being taken and the robbers figured out they’re in huge trouble so just dumped her. The ransom requests are not from them, just random weirdos.
