Robyn Gardner of Frederick County went missing in Aruba where she was traveling with a man from Gaithersburg named Gary Giordano.
A judge in Aruba has ordered a Gaithersburg man to remain in jail in connection with the disappearance of his traveling companion, according to the Associated Press.
The judge has ruled that prosecutors have enough evidence against 50-year-old Gary Giordano to continue holding him while they investigate the disappearance of Robyn Gardner.
The two traveled to Aruba together earlier this month, but friends and family became worried when they could no longer reach Gardner.
Giordano has said the 35-year-old Frederick woman failed to make it back to the beach when the two went snorkeling. But authorities are questioning his account of what happened, and are trying to find and interview anyone who saw them together on the island.
Gardner's body hasn't been found, but officials say she is presumed dead. Giordano's attorney has called for his client's release, insisting that he has cooperated with the investigation, and that prosecutors have no proof that he has committed a crime.
Other Montgomery County women have previously accused Giordano of domestic abuse or making threats against them.
