<human>: Can you condense the text into a few key points?

My mom's friend has been going on about this guy she met online who apparently is an engineer working out of Cambodia. After a couple months of talking, he said he was stuck in Cambodia and needed money to come visit her. So, what does she do? SHE WIRES HIM $8,000 DOLLARS AND SENDS HIM HER BANK ACCOUNT AND ROUTING NUMBER. We tried telling her it was a scam from the getgo, but she didn't believe as she's an older lonely naive woman whose husband just passed. What can I do to get her money back? Or to bring justice down on these jerks..
