@eoe,
And sadly I think this sort of thing occurs more often in nursing homes than you probably hear.
I worked in one when I was in high school. There was one man that they assigned a male worker to be his "escort" - he could never be alone. He had molested a bed ridden female resident.
There was another woman that had to be watched as well. She would try to escape and wander around. Residents could go out, that were capable, but this woman did not have all her marbles in sense, and would have likely been struck by a car or who knows what. The scary thing was she was very clever about her escapes. Once we were driving not too far from the nursing home and fortunately saw her wondering about.
