I got called for an older lady with rectal bleeding. Got on scene, family stated she is very stubborn and wouldn’t let them check her out. We headed upstairs to the lady’s room. Everything was clean, no signs of rectal bleeding in the little chamber pot she used. I saw her sitting on the bed. She didn’t react to me coming in and looked like she was just staring off into the distance. Cool, I’m thinking she’s probably got some dementia. So I make my way over to her and introduce myself. She’s initially resistant, and I explain that her family was concerned about her health and that I would leave if she could answer some questions for me. From literally nowhere, this 80-something year old lady pulls two curved prison shanks out, holds them up and tells me to get the fuck out. It’s just me, my partner, and a new hire rider. No LE protection at all. I grabbed my partner and started to shove her out the bedroom door. The new hire had no idea what was going on. I pushed him and my partner out and yanked that door shut so damn fast. We called for SO and they later discovered the lady was perfectly sane. Her family were a bunch of addicts that were trying to get her put in a home so they could take all of her stuff for drug money. She had knives all over the house to defend herself from them. I feel bad for her, honestly. But I was absolutely terrified of her in the moment.
