I read last night (from a news source, but don't remember which one) that the US search crew was given specific locations to search (by whom I don't know). But remember Aruba/Dutch LE is not telling the MSM much of anything.
Aruba did not have the equipment to search this quarry and I am sure once the Dutch heard the team was coming from the US they decided to let the US team search the specific areas.
Last nite on Geraldo one of the Texas ES mmembers startled Geraldo by saying he believed they would find her within the next 2 days.
Geraldo asked how he could be sure and I can't remember the exact response. Said something along the lines of they were confident and that Natalee was going home soon one way or another.
These people seem to be committed and unswerving, just like Beth.
