Oranjestad , Aruba ( CNN ) -- A judge ruled Monday that there was enough evidence to continue holding a U.S. man in connection with the case of a missing American woman , Aruba 's solicitor general said . Gary Giordano , 50 , was arrested by Aruban police on August 5 , three days after Robyn Gardner , 35 , was last seen near Baby Beach on the western tip of the Caribbean island . The decision to hold Giordano for 16 more days was issued after a jailhouse hearing Monday afternoon , Aruban Solicitor General Taco Stein said . Giordano will be transferred from the jail to a prison Tuesday morning , Stein said . Meanwhile , clothing found during a search of Aruba 's phosphate mines does not belong to the missing woman , Stein said . The clothing was discovered Friday when crews were searching for Gardner , . Giordano 's attorney urged authorities on Sunday to release his client . `` Today , nine days later , four voluntary interviews , two site visits , and more than 30 statements coming from different sources including witnesses and professionals , we can not deduce that there is hard proof to sustain a demand by the public prosecutor against our client , '' Giordano 's attorney , Michael Lopez , said in a written statement . `` In anticipation of any possible reason of prolongation of the client 's detention , we can state that no felony has been committed by him , '' Lopez said . `` The Department of Justice at this time does not have any basis to request prolongation of his detention . '' According to Aruban prosecutors , the missing woman and the suspect arrived on the island July 31 from the United States . Lopez said last week that his client came to Aruba on vacation with a female friend he had met on a dating site and has known for years . Giordano told authorities that he had been snorkeling with Gardner , when he signaled to her to swim back , according to a statement from the prosecutor 's office . When he reached the beach , Gardner was nowhere to be found , he allegedly said . Stein said Monday that Aruban authorities are holding Gardner 's passport so it is not possible that she has left the country . Lopez denied statements by prosecutors that his client is no longer cooperating with authorities in the investigation . The attorney said in his statement Sunday that Giordano , whom he identified by his initials , GG , has given `` all possible cooperation . '' `` The client has his own business and family in the United States . He has no reason whatsoever to obstruct any investigation , '' Lopez said . He added that his client could be returned to Aruba `` in case any legal proof shows up . '' FBI agents on Friday searched Giordano 's Gaithersburg , Maryland , home , Special Agent Rich Wolf told CNN . CNN 's Tristan Smith and Martin Savidge contributed to this report .
