Oh wow. I didn't realize that she would need to change her email address. This current scammer found her via Instagram, which I thought was kind of strange, but if her Instagram account is linked to her email address and the other person had her email, then maybe that's how he found her. Anyway, I know for certain she did not change her email address after the first scam.
I have photos. I also know his Instagram account, although it's set to "private" so I cannot see anything other than his profile pic and username. I did a reverse Google image search on the pics (she's sent me additional photos) and no luck. I also found a website for scam artists and the pics didn't show up on there, either. I just feel like I have no "smoking gun" that will demonstrate this guy is fake, so she's never going to believe me.
But thanks. I'll keep being her friend and supporting her and encouraging her not to send money. It's just so hard to watch her go through this.
ETA: I just Googled her email address -- she has a very public profile (for reasons I won't get into here so that I can protect her privacy to the extent possible), so even without her email address, if a prior scammer had her full name, which he definitely did b/c she sent him money and a cell phone, he could have put that up and it would take someone 3 seconds to find her online. And now this makes so much sense why this person contacted her via Instagram (which is public) vs on a dating website. Oh gosh. I just feel awful.
