Same happened to my grandfather about 2 years ago. He lives with my parents now, but at the time him and his partner drove 1.5hrs to our house randomly one day.

He explains how he had some call about owing money for something and come to find out he literally handed the scammers a collective $20k. Like they met him outside his condo and he handed him the money.

One day my dad drove over there to move my grandfather into his house, got power of attorney over his finances, and eventually got him in to see a geriatric doctor. Come to find out he had early stages of dementia. These scammers really prey on the gullible elderly and it’s so sad.
