Let me see if I can think through this a bit ...
At some point the male started raping this woman (was she really the only one?!).
At some point the family was told what was going on.
The family then researched cameras, bought one, set it up, and captured the male committing rape.
My point: Why in Hades did the family not trust the nursing home to handle the situation properly? Their course of action suggests they knew the nursing home manglement could not be trusted to protect their loved one. Those manglers and stuporvisors got some 'splainin' to do, to the police and DA, IMO.
As for the male, find a part of the ocean where the sharks are hungry.
