BINGO
You have the answer. The nursing home was making $5,000 a month off this poor old lady and they dont give up that kind of money easily.
Kidnapping --Life sentence--at 84 I would rather be in prison than a nursing home. Is there really that much difference? The prison doesnt smell like Urine and you done have Alzheimers patients roaming in and out of your cell. Most of the younger prisoners would probablt look out for you a little and you would be around some younger people instead of others who are dying. Given a choice I might take prison.
In fact the worry of paupering your kids is gone ,prison is paid for ,they dont have to sell everything you own to keep you there.
