Jilted lover of woman missing in Aruba: Her email was hacked after disappearance

The jilted boyfriend of a blond Maryland beauty who went missing in Aruba last week said he believes someone was tampering with her e-mail account in the days after she vanished.

Richard Forester, 40, told People magazine he tried to Gmail chat with on-again-off-again squeeze Robyn Gardner, 35, after she split for a Caribbean vacation with another man without telling him.

Gardner's travelling pal reported her missing on Tuesday, Aug. 2, but Forester said her e-mail account was active on Wednesday and Thursday.

"The way you know they're on their Gmail chat account is there's a green light," the Washington, D.C., headhunter told People. "If you're … not doing anything on it, it tus idle and tus orange. If you sign off, it tus gray."

"Throughout Wednesday and Thursday her indicator lights were green, orange and gray. This was after she was reported missing. So someone was on her Gmail account," he said.

Forester has said he doesn't believe claims from Gardner's Caribbean companion, Gary Giordano, that she vanished while the two were snorkeling at the Nanki Country Club in southe Aruba.

"She wouldn't have gone snorkeling and gotten her hair and makeup messed up," he told People. "She would have been drinking by then. She would have been laying out by the beach."

Forester also said Giordano's ex-girlfriend told him Giordano was "technologically savvy" and "would get into a person's email account … and take on that persona," People reported.

Giordano, 50, of Frederick, Md., was arrested on Friday after attempting to board a plane out of the country.

He was being questioned by investigators and has not been charged with anything.

But the tropical island mystery is not his first run in with the law.

Giordano was divorced from his wife in 2008 amid allegations of domestic abuse, and at least one other woman sought a restraining order against him, ABC News reported.

He also has several arrests for theft, court records show.

Giordano's lawyer, Michael Lopez, said his client is innocent and being unjustly detained.

Christina Jones, a friend of Gader's, told the CBS "Early Show" that Giordano and Gardner were friends, but had "a bit of a rollercoaster" relationship.

"Good one day, not so great the next," she said.

Both Jones and Forester said they had heard about Giordano but never met him.

The disappearance comes more than six years after Alabama high school student Natalee Holloway vanished while vacationing in the same resort town.

That case is still unsolved.
