MIAMI -- A woman whose husband disappeared during their honeymoon cruise in the Mediterranean could have been drugged before being found unconscious in a corridor last summer, a lawyer for the husband's parents said Thursday.

Brett Rivkind, the lawyer for George Allen Smith IV's parents, said he doesn't have any evidence to prove that, but suggested it as a possibility. The FBI is investigating the disappearance of Smith, 26, of Greenwich, Conn., who vanished July 5 from a Royal Caribbean International ship while on vacation with his wife, Jennifer Hagel-Smith.

No one has been charged and no body has been recovered, although blood stains were found running from the balcony of Smith's cabin to life boats. Smith's family has accused Royal Caribbean of covering up the disappearance, but the company denies that.

William Wright, senior vice president of marine operations with the Miami-based cruise line, also questioned the possibility that Jennifer Hagel-Smith was drugged. He said crew members who found her didn't notice anything unusual about her behavior.

"She woke up. She was cognizant. She was saying repeatedly that she was fine and that she simply wanted to go back to her cabin," he said Thursday.

Hagel-Smith and her attorney say she was unconscious and has no recollection of what happened.

"Why I was there, why I was unconscious I don't know," Hagel-Smith said Thursday.

Hagel-Smith said she passed an FBI polygraph test. Federal authorities have said she has cooperated with the probe.

Rivkind said it has been difficult to get information about the case because Royal Caribbean hasn't been forthcoming.

But Wright denied that, saying the company has been cooperating with the investigation and authorities, including the FBI, from day one.

The cruise line said in a statement Wednesday that Smith's wife, Jennifer Hagel-Smith, was found sleeping in a corridor far from the couple's cabin the night he vanished. She told crew members that the couple had been partying, the company said.

The cruise line also said Wednesday that the FBI was investigating an alleged rape of a female passenger by the same three young men last seen with Smith. Wright said the couple and the three men had been hanging out frequently with the men before Smith's disappearance.

When Rivkind was asked whether the three men were involved in the disappearance, he said he would leave that up to the FBI, which has declined comment.

James Walker, Hagel-Smith's attorney, slammed the cruise line for not getting her medical help or noticing blood around the cabin.

Royal Caribbean, meanwhile, accused Hagel-Smith and her attorney of waging a public relations campaign with false claims that she was mistreated.

"She was unable to help us because of the condition she was in," said Lanny J. Davis, an attorney for Royal Caribbean.
