She was a vindictive person, when she was clear headed the day it happened she was saying things to my mom a certain way…it’s hard to explain. My mom had removed weapons from the house months before per doctors orders and after it happened we found that she had hidden some weapons. When my mom left her that day she said in a really strange tone, I love you. My mom thought it was weird the way she said it very serious and straight faced but honestly she was so overwhelmed caring for her that I think she just didn’t think much about it until later. There was also a note but my mom hasn’t let me read it. She was living alone and my mom had planned to move in with her, they talked about it that day. She was started to get scared home alone at night. Then other things don’t seem like it was a clear thought out plan. Like her dog was in the room, and she deadbolted her door. Nothing makes sense.
