Part 2 - "Paralyzed by DIFFICULT Mother in Law". Should we report her to APS?

Thanks for all the responses to my original post, made approximately one year ago. Over the past year, mother in law has made multiple accusations that my wife is stealing from her - small household items, food out of her refrigerator, and of course, money. Mother in law has no fundamental trust in my wife or any of her children (all estranged from the mother in law). So.. mother in law has sold her "stealing" narrative to her brother, who believes her and is a bullying, vindictive personality who just throws gasoline on the situation, adding no positive support at all. THEREFORE, my wife has walked away from her caregiver duties and has provided all local support information to mother in law's brother who lives in NEW JERSEY (we're in Nevada). So here is my fundamental question- SHOULD WE REPORT MOTHER IN LAW AS A CASE TO ADULT PROTECTIVE SERVICES ? We realize that we cannot force mother in law to do anything (get weekly support) without documentation. However, I am sick and tired of mother in law accusations that my wife is stealing. I wonder if this reporting might better document the situation and protect us against any bullcrap accusations and a bullying vindictive brother... thanks for any insight and thanks again for all your previous responses, which I have reread dozens of times.... dmy
