Aruban police and U.S. investigators, endless media coverage, numerous leads, $1 million reward — why haven't there been any breaks in the Natalee Holloway (search) case? We'll get insight from retired FBI agent Harold Phipps, Tito Lacle, investigative reporter for Aruba Today, Aruban attorney Arlene Ellis-Schipper and Art Wood, investigative reporter for El Diario.

Then, Beth Holloway Twitty, Natalee's mother, briefly returned home to Birmingham, Alabama. But now she is back in Aruba. Why did she come back to the Dutch Caribbean island so quickly? Beth Holloway Twitty joins us with the latest.

And, it's been one month since George Smith (search) disappeared on his honeymoon cruise in the Mediterranean. With few leads and clues, have investigators uncovered anything into Smith's mysterious vanishing?
