Zelle

While I was living in Florida, I was living with my dad and my aunt (she's 78 and my dad's 80)

they both don't know how to use phones and my dad would always ask her for money to borrow , for maybe 2 years. instead of her going to the bank, I would zelle myself from her account. She willingly and knowingly accepted this each time. When my dad had his stroke , she called her daughter who lives in California to come get her and take her back to cali. she came to Florida and when they went to the bank they got all her bank statements she saw all the zelle transactions to my account and said that she reported me and my dad to the FBI for wire fraud and elder abuse because she has dementia. The money was NEVER forced out of her or scammed she always agreed. Her daughter is now basically telling her what to say and my aunt is now saying she never authorized it. There is NOTHING other than zelle transactions no written anything. Can she do anything ?
