'The Case Of: JonBenet Ramsey' Fills in Important "Missing Piece" of the Puzzle (Exclusive Video)

Back in late December 1996, all eyes were on the mysterious murder of 6-year-old beauty queen JonBenet Ramsey.

In addition to the media storm that erupted around the homicide, the long-running investigation into her death drew a slew of detectives, prosecutors, forensic specialists, and members of the FBI.

However, as The Case Of: JonBenet Ramsey executive producer Tom Forman explains in The Hollywood Reporter's exclusive video above: "The investigative team felt like there was a missing piece the first time around, that there was one expert they should have had back in 1996 they just didn't have" — until now.

In the upcoming six-part docuseries slated to premiere on CBS later this month, that missing piece — a victimologist — plays an important role in the extensive investigative team assembled to reexamine the 20-year-old cold case.

A victimologist, as represented on the team by former New Scotland Yard criminal behavioral analyst Laura Richards, looks at the victims and attempts to figure out how they lived in order to find new clues into how they died, and, potentially, who killed them.

"It's such a confusing crime scene with so many mixed motives and things that were done to her," Richards says in the video. "It's why it never made sense."

With so many different docuseries attempting to reexamine the JonBenet case (A+E, HLN, NBC's Dateline and Investigation Discovery also have projects), the pressure is on for The Case Of's team to find new clues and new answers about who killed Ramsey.

Meet the rest of the intrepid investigators in the exclusive video above.

The Case Of: JonBenet Ramsey debuts on Sunday, Sept. 18 at 8:30 p.m. on CBS.
