Giordano tried to redeem Robyn Gardner insurance policy
Investigators were trying to determine if there was anything unusual or striking about the policy. "If you change the policy around and make it higher or whatever, then it may be of interest to the investigation but we haven't established that yet," he said.
ABC news, citing an unidentified police source, first reported that Giordano had taken out a $1.5 million American Express insurance policy on Gardner and that it was being considered as a possible motive in her disappearance.
Giordano's attorney, Michael Lopez, did not respond to a request to comment on the insurance policy. The attorney has previously said that there is no evidence that Giordano committed any crime and that he should be released.
Giordano, a 50-year-old business owner from Gaithersburg, Maryland, traveled to Aruba with Gardner on July 31 and reported her missing two days later, saying she disappeared while the two were snorkeling.
He initially assisted the search but was detained at the airport as he tried to leave Aruba. Authorities said they had found discrepancies in his story.
Giordano, a twice-divorced father of three sons, has denied any wrongdoing through his attorney.
A judge ruled Monday there is enough evidence to hold him for at least 16 more days on suspicion of involvement in Gardner's presumed death. The woman's body has not been found and Aruban authorities on Thursday were preparing for a new, large-scale search of the island for her remains or other evidence.
Investigators are seeking to collect enough evidence by the next detention hearing to hold him for another 60 days and proceed to trial.
The FBI, which searched Giordano's home in an upscale Washington suburb, has been assisting Aruban authorities with the investigation and has put out a missing-person poster with three photographs of the 5-foot-4-inch blonde, including one showing a jungle-print design tattoo on her left shoulder. The poster urges anyone with information about Gardner to contact the FBI or the nearest U.S. embassy or consulate.
The exact nature of Giordano's relationship with Gardner, who had a boyfriend back home in Maryland, isn't clear but the prosecutor's office has said the couple stayed in a room together at a Marriott hotel in Aruba.
Investigators said they have little information about what the couple did and how they behaved while on the island and have appealed for any witnesses to contact police.
