Romance Scam Story - $100.0 Lost

I need advice on how to handle my brother—he’s been caught in a “love” scam for around three years and refuses to listen or acknowledge it. He gets angry and defensive whenever the topic comes up, so it’s been impossible for the family to intervene. Here’s the situation: He works night shifts for daytime delivery, but has been sending daily money transfers via Remitly to a supposed “woman” in Morelia, Mexico. The scam began with her claiming to work for Apple as a CEO, but later her story changed to being a vineyard tender with several helpers—he believes she can’t pay them without his money. He thinks if he doesn’t send money, she risks incarceration. His desperation and blindness are extreme—even when his bank sends low-balance alerts, he continues sending money. When he lost his delivery job, he started stealing from household members and borrowing money under false pretenses (for example, asking for $100 for “gas” and never repaying). He even stole gold coins from a sibling to broker money for this scam. It’s been ongoing for three years, and it feels like it’s getting worse, not better. He’s stubborn and refuses help. Are there legal steps I can take?
