Sorry, perhaps I wasn't clear. The earlier stories were reported in the UK papers but occurred in the US. If this poor chap is indeed American, it's the first case I've heard of where the pensioner was abandoned in the UK. And apparently he has dementia, so cannot communicate with the people looking after him. As to why people do it, I imagine it has to do with the costs of funding social care in the US, especially for someone with the complex needs of a dementia sufferer.
