In that context, I would think that Azabache has it right.
This must have been said with a smile, I hope, since "desgraciada/o" (pronounced /de gra see ah/ or /de gra see ao/ in colloquial Dominican usage) is not a nice thing to call anyone. It's sort of like:
Hi, you old S.O.B.!
Therefore, both Azabache and I do hope that this was a freindly greeting
