My Husbands Mom Helped A Friend And Just Found Out Her Friend Was Poisoning Her

Please bear with me as this is a longer post. So my husbands mom, we can call her C, has gone through so much in her life. She has suffered loss after loss; just about a month or two ago she lost two close friends in a house fire. Well, she has had this friend, we will call her J, for about 30 years or so. They’ve raised their children together, saved each other from significant others etc. Recently, J and her husband had a domestic dispute and had to be separated because the husband was on parole (not really sure in the details here, just what J explained to C), and C offered to let J stay with her for a couple of months while she figured out her next course of action. Now C unfortunately got into some legal trouble with drugs probably almost a year ago now and she’s on reporting probation. She has been doing everything right, though. She passes every UA, she doesn’t hang out with felons etc she just wants to do and be better. Here’s where things get weird. So a couple weeks ago, J disappeared and wasn’t answering any messages or calls from C. Well C got fed up because she had already been catching J in weird lies, like she claimed that her doctor was in the same town as C when they were not. Eventually, C notified J that she just needed to come get her things if she wasn’t going to be living there and that was all. Skip forward a few days and J is in the hospital and claiming that she’s been diagnosed with congestive heart failure. When she’s released from the hospital, J looks horrible and afraid she’s going to die, so C brings all of her kids (they are all adults now) to visit with J. This congestive heart failure game goes on for a couple weeks, and then J disappears again until this past Saturday night. C came to visit my husband and I on Saturday, and we live one and half hours from C so it’s not like a super quick drive. While over here, C looks at her cameras on her phone and wouldn’t you know it, J is at the house getting her items, obviously she waited until C was not home to do this. So of course she had to leave our visit to rush home and hopefully catch J, which she didn’t unfortunately. C calls us on Mother’s Day, and in tears. J stole a bunch of her things; things as stupid as toilet paper and dish soap, to things that had extreme sentimental value, like a flannel that C received from an ex that passed away, and a bracelet charm that belonged to her niece who died last year. J then blocked C on all social media. Over the last couple of days, C has been realizing that there’s something is wrong. First, all her fish were dead (this happened while J was still in the home), then her cats were sick (a couple days before J left), then she got sick (like REALLY sick) and has been for a couple days now. Well she was going through her fridge last night and got a water bottle and when she opened it, she noticed it smelled like bleach. She opened a second bottle and same thing..so she went to her primary care and yall would not believe what the tests said! First, her white blood cell count is craaaazy high. She tested positive for a multitude of things; ecstasy, mdma, meth, and evidence that she’s ingested BLEACH! She called my husband hysterical after her appointment. I feel horrible for her. She has lived alone for I think around 3 years now, and lives in a small town far from any major city, because she inherited her home. She was excited to have a close friend staying with her, to have some companionship again, and this is what she gets. So I’m here to ask for some advice. She’s spoken with her po to let her know the situation, but she talked to her po before her doctors appointment. She’s afraid of getting the cops involved because of what was found on her tests, but at the same time she can’t just let J be out and about and free to possibly come back and do something even more insane. We would really appreciate any advice that anyone could give us, legal, supportive whatever you may have just please ????
