Welfare check on bedridden woman with dementia requested

Caller (name withheld) is requesting well-being check on his sister, 74-year-old (name withheld).

She's supposed to be bedridden and suffering from dementia.

Her nephew, who's supposed to be taking care of her, has blacked her collar and now the sister's not answering, which normally she does.

Clear.

Thank you, and caller would like contact.
