So sorry OP but I think this. Figure out your moms options and then get firm with him - offer to hire a service, maybe make a trip out there. (Your sister sucks BTW.) if he still doesn't budge get the POA and figure out a way to get her into assisted living near you - a facility that graduates to nursing and/or Alzheimer's care if you can. Don't sit too long waiting for him. Move now.
Signed, way too much experience with this stuff
