See post #1943 where I talk about this. A girl from Aruba who posted here yesterday and before that wrote that "Lorenzo" (who the police talked with just before bringing in S. Croes) had Natalee in the basement of his house. Now we have not heard anything about Lorenzo and that story since.
Yeah, I saw your 1943 right after I posted and wished I had taken the extra effort to connect the two things instead of getting lazy.
I've been trying to remember more specifics about that helicopter search, but the only thing I can remember was that the search was conducted at night. And I'm not even 100% sure of THAT.
Shortly after I heard about the infrared search, I read the "Lorenzo's basement" story at SM or somewhere. Gave me a cold chill when I read it.
