Police in Boulder, Colorado, are refuting assertions that there is viable evidence and leads about the 1996 killing of JonBenet Ramsey that they are not pursuing.

Investigators collected someone else's DNA from JonBenét’s fingernails and her underwear. Ultimately, the docuseries calls into question the validity of the DNA testing, but it had been previously determined that neither Patsy, John, nor Burke matched it.

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.
