The first trailer for CBS' docu-series The Case Of: JonBenet Ramsey debuted on Tuesday, revisiting the murder of 6-year-old pageant star JonBenet Ramsey. Ramsey was found dead in the basement of her Colorado home on Dec. 26, 1996, and the high-profile case is still unsolved.
However, the six-hour limited series aims to change that. The trailer features a team of experts -- as well as a few of the original investigators -- who re-examine the evidence nearly 20 years later. The crime scene is even recreated by rebuilding full-scale replicas of key rooms from the Ramsey house.
"We hope to get the truth out about how she died," retired FBI Supervisory Special Agent/Profiler and former prosecutor Jim Clemente says. "She's not gotten justice yet."
The trailer opens with the eerie 911 call from Ramsey's mother, Patsy (who died in 2006 after a battle with ovarian cancer), who reports that there's been a kidnapping in their home. Shortly after, both Patsy and Ramsey's father, John Bennett, deny they had anything to do with the murder.
The series will air on three nights in two-hour installments, beginning Sunday, Sept. 18 at 8:30 p.m. ET/8 p.m. PT on CBS.
In February, the Internet was buzzing with conspiracy theories claiming that Ramsey's unsolved murder was all a ruse. In a resurfaced YouTube video from December 2014, a man named Dave Johnson claims that Ramsey is not dead, but is in fact pop star Katy Perry.
