(NEW YORK) -- The boyfriend of missing Maryland woman Robyn Gardner said Friday that he agreed with the man who is suspected in her disappearance that human traffickers may be involved.
"Human trafficking, yeah absolutely, that's something I've been thinking about the entire time, since day one," Richard Forester told ABC’s Good Morning America.
Forester spoke a day after Gary Giordano, the lone suspect in Gardner's disappearance, told GMA that the woman disappeared in an area that is known for activity by traffickers.
"I think it's very possible and I wonder what (Giordano's) involvement was," Forester said. "There's a whole underworld down there. I don't know what he knows about Aruba."
Forester appeared on GMA to respond to Giordano's first interview since being released Tuesday night from the Aruba prison where he spent four months as a murder suspect in Gardner's disappearance.
No charges had been brought against Giordano, and prosecutors have not found a body, a motive, or a weapon.
Giordano, 50, who met 35-year-old Gardner on a swinger's website a year before they decided to go on vacation to Aruba together, told prosecutors that Gardner been swept out to sea in rough currents while the two were snorkeling one evening. Prosecutors have said that Giordano's story doesn't add up.
On Wednesday, Giordano appeared to suggest during an exclusive ABC News' interview that Gardner may have been kidnapped as part of a human trafficking crime.
Forester and Gardner were living together most of the time when she disappeared and he has said they were planning to get married. He did not learn that she went to Aruba with Giordano until after she vanished.
Forester said Friday he still believes Giordano should be held responsible for her disappearance.
"Where's Robyn? Where is she? You're the last one to see her," he said of Giordano. "Where'd she go?"
"I believe that he being the last person to see her and be with her is responsible."
