Oh wow. I got EXACTLY the same message, only with a sick dog and an asian woman in a car. I did the exact some response you did too. So weird.
The profile picture was the smiling face of an Asian girl. I didn’t bother to respond.
This was followed by the text "hi, is this Grèg frm Sañta Barbara?.? It is Jennifer."
Clearly some sort of scam is afoot, but I don't know what it is. And virtually no effort has been made to be at all convincing, given the diacritics.
