Giordano said nothing as he arrived on an American Airlines flight from the Caribbean island Wednesday.

Giordano has denied any wrongdoing in the disappearance and presumed death of Robyn Gardner. He was released from an Aruban jail Tuesday after a judge ruled authorities lacked enough evidence to continue holding him. Prosecutors have appealed and expect a ruling Wednesday.

The 50-year-old Gaithersburg, Maryland, resident was accompanied by his attorney Jose Baez, who got an acquittal for Casey Anthony in her murder trial in Florida this year. Giordano and Baez went into American Airlines' private club. It was unclear if Giordano was awaiting another flight.

Giordano has spent nearly four months in custody while investigators have sought more time to gather and evaluate evidence in the death of the 35-year-old Gardner, whose body has not been found.
