Executive-produced by Richard LaGravenese ,who serves as showrunner,

JonBenét Ramsey explores the tragic unsolved murder of the six-year-old beauty queen of the same name. The show follows the Ramsey family, before and after the tragedy, as they go through the painful loss of a child, while facing intense public scrutiny caused by a media frenzy that caused this case to captivate an entire nation. At the heart of the series is the story of Patsy and John Ramsey – exploring the unbreakable partnership of these two complex people – as husband and wife, as mother and father – who had committed themselves and their children to building the narrative of a perfect, privileged life, only to have it destroyed one Christmas night in 1996.

Harrison Query and Tommy Wallach sold the project to MTV Entertainment Studios and 101 Studios and serve as writers alongside LaGravenese.
