In a statement, the bank told the site that when handling a foreign currency deposit made by Ruth, a bank clerk accidentally put her account number into the amount field by mistake.
"On Tuesday, December 10, our client made a foreign currency deposit into her LegacyTexas account. Due to the fluctuation in exchange rates, all foreign currency transactions must be manually entered into our system through our back office. When our client's deposit was being keyed in, our representative entered her account number into the amount field by mistake," they said.
"Although our client brought the error to our attention and the transaction was immediately reversed, less the amount of her original deposit, it would have been caught and corrected during our evening processing. Rest assured, our systems are sound, and this manual entry error has been addressed."
So not only did the bank strip her of $37million in one day, they also might have have just told the world what her bank account number is.
Either way, there's one thing they cannot take away from Ruth: "I was a millionaire, I have a screen shot of it so I can say that now," she said. "It's quite a story."
