The country has been transfixed this year reliving a murder trial from two decades ago (see: The People v. O.J. Simpson; O.J.: Made in America), and now CBS is revisiting another famous murder.

The Case of: JonBenet Ramsey is a true-crime limited event series that reunites the original investigators of this unsolved murder and teams them with new experts — including a former New Scotland Yard criminal behavioral analyst and a retired FBI supervisory special agent — as they re-examine the 1996 case of JonBenet Ramsey, a 6-year-old beauty pageant contestant who was found dead in her home in Boulder, Colorado after her parents reported her missing.

The six-hour series, executive produced by Tom Forman (Extreme Makeover: Home Edition, 9/11), airs on Sept. 18, 19, and 25, and a new trailer for the program shows the team poring over the evidence, aided by technological advances and new interviews, and generating new theories. A replica of key rooms in the house has even been constructed in a 50,000-square-foot warehouse. Step inside the show with this just-released three-minute preview.
