(NEW YORK) -- The boyfriend of the Maryland woman missing in Aruba for more than seven days says he doesn't "believe for a second" that his girlfriend vanished while snorkeling, and raised new allegations against the man being held as a suspect in her disappearance.
"I'm terrified," Richard Forester said Thursday on ABC's Good Morning America. "I've been hearing stories about Gary Giordano, that he's quite tech-savvy and is able to manipulate people's computers and track them and follow them."
Gary Giordano, 50, is being held as a suspect in the disappearance of Forester's girlfriend, Robyn Gardner, 35, of Frederick, Maryland, who vanished in the same Aruba town where another American woman, Natalee Holloway, disappeared six years ago.
Giordano and Gardner traveled together to Aruba on July 31, according to Aruba police.
Gardner's best friend, Christina Jones, told GMA that the two met on the online dating site Match.com and have known each other for one year.
"It was a bit of a rollercoaster relationship/friendship," Jones said.
Giordano has claimed that he and Gardner went snorkeling together around 6 p.m. on Aug. 2, but Giordano returned back to shore amid rough currents and realized Gardner had not returned to shore with him. He alerted Aruba police who searched the area with ships, helicopters and divers, but did not find any sign of Gardner.
"I don't believe she was snorkeling," Forester, also of Maryland, said Thursday on GMA. "I don't believe that for a second. She would be too concerned with getting her hair messed up, getting her makeup messed up. She's a margarita kind of girl, sit by the pool or on the beach and relax. I don't buy it."
Forester said that during Gardner's trip to Aruba, they kept in touch through Blackberry text messages and emails from her iPad until the day of her disappearance, including one message, in particular, that raised his alarm.
"On Tuesday morning, the second of August, at about two in the morning, she posted on my Facebook wall, 'this sucks,'" he said. "I tried to figure out what was going on, but she didn't really respond."
"The last time I heard from her was later on in the afternoon," he added. "She sent me a message saying, you know, 'I love you, we'll talk and sort things out when I get back.'"
