But Im so sorry you are going through this shiit

Dang.  Back in the 'olden days' before internets and cell phones, my grandfather was the target of scammers.

He wrote thousands of dollars of checks before my mom found out. She promptly "hid" his check book.  I know that this helped, just like she hid his car keys from him when he was too dangerous to drive but the DMV wouldn't take his license until he hurt someone. Note she never took them out of his place, just hid them from him.

The retirement home watched in-person bank withdrawls so cash scams weren't very easy there.

Dang. If the police and APS won't do anything, you are definitely limited. If it were my mom, I'd get it before a judge and have her declared her mentally incompetent. If something isn't done, they will scam her out of the last dollar. She will loose everything. There are even documented stories of people selling their homes to give to these people. Your only other option is to be clear with her...once you've let the scammers take all your money, do NOT come here looking for help. You will end up homeless or in a nursing home. (Or whatever you can think of to shock her out of this mess).

I do know DH's friend overseas never stopped sending money to his scammer....but fortunately for him, he had a set amount of "support" for his lady each month. SMH

I'm sorry. This is really terrible.

This is going to sound odd, but does she watch Dr. Phil? Or would she? He frequently does shows on people who are being scammed romantically or just financially. I am not a big Dr. Phil fan, but he does seem to do good with these types of people. He goes to great lengths to prove they are being scammed and it seems like he often gets through to them, especially the ones where there is no romance. Maybe she could watch some episodes? Or even go on the show?

The only reason I know this is because my Mom watches Dr. Phil!

I am a social worker who works with seniors for a Medicaid Waiver program. Unfortunately, there is little you can do. There is a saying that we often reference at work: "people have the right to make poor decisions" and your MIL is making poor decisions. It is devastating to watch but if she is competent, then it is her right. Now if you believe she is not competent, you can petition the courts to appoint a conservator or guardian; it could be a public conservator or guardian if family does not want to be involved. But if she is competent, MIL will likely hand over all of her money to these scammers and as CajunMom said, she will end up in a nursing home or homeless if she doesn't have family bail out. I would make that clear to her upfront and then just let the cards fall where they may. 

One day, I received a call from a young man who addressed me as "Grandma".  He said he'd been on a trip with some buds to Kentucky and they'd had an accident.  He was driving and hit someone and was in jail.  He'd broken his nose in the accident.  My thoughts immediately went to the youngest GS who was living a wild life with some friends.  He said a lawyer could get him out of the jam but it would take about $2,000 and I'd have to send it right away.  He gave me the lawyers name and number and begged me not to call his parents.  

I called the city jail where he said he was and they had no record of him.  I googled the lawyer name but couldnt find him.  I called my daughter, explained the situation and she and SIL went and verified GS was sleeping in bed.  When the lawyer scanner called, I gave him a piece of my mind and slammed the phone. Looking back, I should have reported it to the police.

I thought the broken nose was a nice touch - in case the voice sounded unfamiliar.

Look up Scammer Payback on youtube. Pierogi is a brilliant young man who calls the scammers using an old lady voice, and lets the scammers walk "her" through giving them access to their computer & bank accounts. The scammers pose as Microsoft or an anti-virus company.what they don't know is that Pierogi uses their connection to access the scammers computers (while stalling for time acting like a non-tech savy older woman). Pierogi deletes the scammers files (=data from their victims), wastes their time, activates their webcams & captures photos & video of the scammers, and (after the delete is done), lets the scammers know he's got their exact location. He also speaks Hindi & taunts them (hilarious!) & laughs at their insults. He shares his findings with the Feds & also calls current victims-in-progress (from the scammer's data) to alert them & warn them NOT to transfer money or buy gift cards (=scammers instruct victims to buy multiple $500 gift cards then read them the code to avoid dection). Pierogi of Scammer Payback is a high-tech hero!

Cops can't help because it's federal / international.crime - they don't have jurisdiction or resources to help. 

Hope this info helps!

Is constantly falling for scams.   Ive fixed his computer many times after ransomware, etc.

His cell phone rings constantly with scam artists.   Ive warned him that microsoft, google etc NEVER  call you uninitiated.   Sigh.
