A judge in Aruba ordered a Maryland man remain in jail without bond another 30 days.
Gary Giordano is suspected in the presumed death of his travel companion, 35-year-old Robyn Gardner, of Frederick, Md.
Giordano denies wrongdoing and says Gardner was swept out to sea while snorkeling Aug. 2. Her body has not been found.
Investigators became suspicious of Giordano because he tried to cash in on a travel insurance policy he took out on Gardner and there were inconsistencies in his story, authorities have said. He was detained Aug. 5 at the airport before he could leave the island.
