My Godmother Has Brain Cancer And Lung Cancer

My location: Arizona

My godmother's new location as of yesterday: Indiana

(I hope I selected the right tag bc this might involve Wills/Trusts as well)

My godmother has been like a second grandma to me all my life and as of the past few weeks she had a tumor removed and she ended up having brain cancer and kidney cancer and was given 3-4 months to live. Her family that live in Indiana, including her grandson, her niece, and her kids (family that I have never seen in my 25 years of life as I've lived right down the street from her) packed up and immediately came down here as soon as they heard to take her back up with them to Indiana for her savings.

My godmother lived with her husband that didn't care for her and had a buddy that claimed to be a "caregiver" but was only there to be able to use their vehicles, stay with them, and use their debit card as he pleased, and his name is Maurice and he's only been around for maybe the past 8 months or so. When my godmother had the surgery for the tumor she explained to me and my mom that Maurice and her husband Chuck have been taking her social security checks for the past 6 months out of her bank account and giving them to Maurice for anything he wanted. He was also using her debit card to pay car payments on a new Dodge Challenger Chuck ended up buying for him. She asked my mom to please go onto her online banking and check to make sure her savings were still in there because she trusted my mom with everything so of course my mom did it for her. She also told my mom to get her bank folder out of her house away from Maurice and Chuck so they wouldn't be able to transfer her savings. My mom checked often since she was told to up until yesterday when they came and got her. My mom has never touched a dime in her bank account and never would because they have a great relationship and my mom is not the type to burn someone in our family like that, she kept checking to make sure everything was there for my godmother and that was it.

My godmother's grandson who I've never seen until yesterday ended up meeting all of us at the bank to try and split up the savings in my godmother's account the way she always wanted it to go: 4 ways between me and my brother and then her niece and oldest daughter I think? It ended up not happening because my godmother didn't have two forms of ID so she ended up leaving to Indiana asap so they were able to have the whole savings.

Her grandson texted me yesterday informing me he's going to have an investigation done about people logging into her online banking and I was honest like I have been and let him know that my mom and Chuck/Maurice were the only ones to be in that account but my mom never touched anything in that account and Chuck/Maurice did.

Is there any possibility my mom could get in trouble for logging into her account because my godmother asked her to? My godmother is starting to have dementia so I don't think she would even recall the conversation that we had at the hospital when she had the tumor removed.

Also, is there anything I could do about giving savings to my godmother to hold for me for a wedding that's in that account? Or should I just kiss it goodbye unless they wanna be nice and give it to me?

Any advice is greatly appreciated because this has been a horrible and terrifying time for me so please let me know.
