While it starts out with a little background on the case, the docuseries quickly gets into the Ramseys as a family, including about JonBenét's mom, Patsy, a journalism graduate.

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.

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.
