Could the young mystery girl found in Greece last Wednesday actually be from the United States?
Authorities are trying to identify the girl known as Maria.
Her parents say she was adopted illegally from Bulgaria.
But investigators say there are leads that could link Maria to the U.S.
The name that keeps coming up is Lisa Irwin, or "Baby Lisa," as she has come to be known -- a girl who disappeared more than two years ago from Kansas City.
Baby Lisa’s parents have heard from the FBI since Maria was discovered, HLN’s Kyra Phillips reports.
