Gary Giordano arrived in Miami Wednesday morning from the Caribbean island. A short time later he boarded a flight to New York, accompanied by attorney Jose Baez, who won an acquittal for Florida mother Casey Anthony in her murder trial earlier this year.
The Gaithersburg, Md., resident did not make any comment while in Miami.
He has denied any wrongdoing in the disappearance and presumed death of Robyn Gardner.
Giordano was released from jail in Aruba Tuesday night after a judge ruled authorities lacked enough evidence to continue holding him. Prosecutors have appealed and expected a ruling Wednesday.
