Giordano, 50, was arrested Friday as he attempted to leave the island on a plane back to the United States. Authorities say Giordano told them he and Gardner, 35, went snorkeling on the evening of Aug. 2 and she never returned to shore.
The pair, both from Maryland, met online and traveled together to Aruba on July 31.
"They suspect murder but there's no proof, to my knowledge," Michael O. Lopez, Giordano's attorney, tells ABC News. "I don't see any proof. There's no proof and there's no motive."
Giordano has a criminal record in Maryland. Two women, one of whom is his ex-wife, have taken out orders of protection against him, records show.
The family of Natalee Holloway, who went missing from the same town six years ago, has also gotten involved in the Gardner case.
