Saturday, July 30

Natalee Holloway's parents breathe a sigh of relief at the news that the blond hair attached to a piece of duct tape is not Natalee's. Meanwhile, Aruban firefighters are draining a lake across from a hotel and searching through a landfill in the ongoing search for Holloway. If these latest leads yield no information, have investigators reached a stalemate in the Natalee Holloway case? We'll get insight from Aruban attorney Arlene Ellis-Schipper and Tito Lacle, investigative reporter for Aruba Today.

Then, how has Natalee's family handled all the ups and downs of the frustrating search? We'll talk with Natalee's father, Dave Holloway, and Natalee's aunt, Linda Allison.

LaToyia Figueroa (search) is five months pregnant and has been missing since July 18. Her boyfriend, the father of her unborn child, is the last known person to see her. Is foul play involved? And does the boyfriend know more than what he's telling Philadelphia police? We'll get an update on the search for LaToyia from her father, Melvin Figueroa, and Simone Weichselbaum of the Philadelphia Daily News.

And, all four suspects in the failed July 21 London bombings are in custody. How did British police nab them so quickly? And, if they're connected to the deadly 7/7 bombings, will they give up their cohorts? Team FOX is live in London with the latest. Then, we'll get the lowdown from Monsoor Ijaz, FOX News foreign affairs and terrorism analyst.

Plus, we'll be joined by:

Dr. Michael Baden, forensic pathologist
Joe Houston, Texas Equusearch member
Robert Cooke, Texas Equusearch member
Harold Phipps, former FBI agent
Brad Hamilton, New York Post reporter
Bill Gavin, former assistant director in charge of FBI
