Robyn Gardner's Last Photo Less Than Two Hours Before She Vanished

Aug. 23, 2011 -- Missing Maryland woman Robyn Gardner was heavily intoxicated when she was last seen alive in an Aruban restaurant, less than two hours before her companion reported her missing during an evening snorkeling trip.

The man with Gardner at the restaurant, Gary Giordano, is being held in an Aruban jail and is the lone suspect in Gardner's disappearance, although he has not been charged with a crime. Aruban police have said they believe Gardner is dead.

Eyewitnesses said Gardner seemed woozy at the restaurant and barely ate her salad.

In addition, a restaurant worker told ABC News he thought it was odd to hear that the couple went snorkeling because Gardner "seemed so perfectly put together," referring to her clothing, hair and make-up.

ABC News has obtained the last known pictures of Gardner, 35, to be taken before her disappearance at the Rum Reef Bar & Grill in the Baby Beach area of the island on the Aug. 2 evening that she vanished.

Gardner's cousin, Kelly Reed, said the family recognized the dress was Gardner was wearing in the photo. And Gardner's live-in boyfriend in Maryland, Richard Forester, told ABC News that it was Gardner in her favorite dress, "with 100 percent certainty."

The time stamp on the photo is 6:12 -- 4:12 p.m., less than two hours before Giordano returned to the restaurant to report that Gardner had disappeared.

A law enforcement source said that Giordano, 50, is seen in surveillance video at 6:02 p.m. tapping on closed shutters of the bar seemingly making his presence known. At approximately 6:20 p.m. he went to the back kitchen of the bar and told someone to call police.

Those who saw the couple at the restaurant tell ABC News they were clearly in a romantic relationship, with Gardner reportedly telling the server, at one point, she was waiting for her "husband" to order.

The server at the restaurant said Giordano "inexplicably" jumped up after the couple sat down and introduced himself, saying, "My name is Gary and this is Robyn and we're from Maryland."The server found Giordano's behavior odd and reported it to authorities.
