Really glad you went to your Father, that you used the police and he is OK as are you and your wife.
My wife and I had to do this, by having to convince a gang from NY to lave my daughter's apartment and to convince them she was gone as they wanted her. That was a rough experience.
Another time I could not reach my Mother for six months and so I drove 14 hours to see if she was OK, but unannounced. She had a caregiver.
I arrived and found my Mother was dead and still in her bed, possibly a month or so. The caregiver was still there and had continued life as he did not want to believe Mother was dead. The local police, County Coroner and Mental health helped a lot. The locals were bad news as her home became a drive by viewing and gossip.
Do check on your elders as one never knows what can happen. And Adult Special Services with Police had been there a few months before and I was never told. I learned *** said everything was ok, but the house was hazard with trash and waste everywhere. It appears the caregiver broke with he work and kept trying but could not function for her or him. Wish I had known, but she is in a better place and had been since her last breath, thus some comfort! Best to all, Jim
