Was Natalee Drugged?

Her Mom Suspects So; Heading To Holland, Where Ex-Detainee Is

(CBS)  "You were there?" Storm said. "You actually heard him say this?"

"Yes," Twitty said. "To at least 10 witnesses. Yes."

When shown another statement from the van der Sloot interview, claiming he'd "never touched a girl in an aggressive way," Twitty said she believes he's lying.

"Oh, absolutely. Absolutely he's lying," she said.

In the interview, van der Sloot says he and the others got together and lied initially to police and to everybody about what happened that night, saying they brought Holloway back to her hotel. Then he says he left her at the beach, but that it was at her request. He says, "I even lifted her up to carry her back to the hotel, and she told me to put her down." He says the only mistake he made was leaving her at the beach.

"The 'only' mistake he made," Twitty said. "You know, I am not even sure if we've gotten to the last disclosed location where Joran last left and saw Natalee. I'm not even certain that that is the last place.

"When Joran led Natalee out of (the bar), she had no ability to make any kind of decision. He even describes her in the same interview (as being) drunk. I don't know what exactly Joran bought her. I believe he had bought her a shot of 151 (rum). Natalee has never had anything like that. I don't even know … what else was in that shot. Joran admits to buying her the only drink that he saw her have that night. He has her talking about a lot of strange things.

"It almost sounds like to me that she is drugged. And in his statements, also, he's saying that she's coming in and out of consciousness. That just doesn't sound like just drunk. It sounds like to me it's a possibility she could have been drugged, also."

Twitty says she's going to Holland "to make sure that everyone realizes and still knows that the reward money is still out there. We have $1 million for a safe return, $250,000 for the whereabouts of Natalee. And we've had posters printed in Dutch that we will be distributing in Amsterdam."
