The case would come to involve multiple law enforcement agencies, private investigators, and even psychics, all trying to answer the question of who killed JonBenét Ramsey. While no one has ever been charged with JonBenét’s murder—and DNA evidence has failed to conclusively identify her killer—numerous suspects have emerged over the years.

One month before the 28th anniversary of JonBenét Ramsey’s murder, Netflix will premiere a three-part “Cold Case” documentary about the Boulder crime, which captivated the world and remains unsolved.

Eight hours later, John Ramsey discovered JonBenét’s body in the basement. She was found with duct tape over her mouth and a nylon cord tied around her wrists and neck. In a move that further compromised the crime scene, John carried his daughter’s body upstairs, removing her from the location where she had been found.
