My sister found a "house" that occupies 11 women. The "nurse" lives in a house next door. My mother refused to go. My sister ended up taking her to the police station and had her committed to the psycho ward because she told the police my mother is suicidal. The hospital tells me if I take her out she will never get into a nursing home when she is evaluated. My mother knows the nursing home she wants to go to. My sister has POA. What can I do?
