Angela said her office could only identify the suspect publicly by his initials: GVG. "He is suspected of involvement in the disappearance of Miss Gardner," Angela said, adding that the man is a 50-year-old U.S. citizen.  The prosecutor's office released a statement later Tuesday that provided more detail. GVG told authorities that he had been snorkeling with Gardner behind Nanki Country Club when he signaled to her to swim back, the statement read. When the man reached the beach, the woman was nowhere to be found, he allegedly told them.  "The statements made by the traveling companion led to such questions that on Friday, August 5, 2011 it was decided to detain him for further questioning on the possible drowning of the woman," the prosecutor's office said in the statement, adding that police are investigating the case.  Media reports, including one from CNN affiliate WJLA in Washington, have identified Gardner's companion on her trip as Gary Giordano.  Michael Lopez, an attorney in Aruba reported to be representing Giordano, could not be reached for comment Tuesday.  The Aruba Herald's website reported Monday that Gardner traveled to Aruba with Giordano, whom she had met on an online dating site and saw frequently. It quoted Lopez as saying Giordano has given extensive declarations to investigators.  Angela would not say what evidence led authorities to suspect his involvement in Gardner's disappearance.  Under Aruban law, a judge sees the suspect within two days of his being detained, Angela said. A judge on Sunday decided authorities may hold the suspect another eight days, she said. "So he'll be detained up until next weekend, and then the judge will see him again, and the judge will decide again if he will remain in detention or go home."
