FORT MYERS, Fla. - "It's a blur right now. We know where she is, what country she's in but we cant get her back," said Robert Hernandez.

His daughter Samantha Hernandez was flying from her dad's house in Fort Myers to visit her mom in Boston. She decided to take a trip to her boyfriend's hometown in Brazil instead. She flew with a falsified passport and authorities in the U.S. never caught on... but the Brazilian government did after taking her into custody.

Authorities released her to her boyfriend's family. Now, Samantha's father says he can't get any help getting his daughter back.

The family's lawyer says there's nothing they can legally do to get the 15 year-old back on US soil. Tuesday, the FBI and immigrations and customs enforcement looked into her case.
