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.

Burke Ramsey has only given one interview since JonBenét's murder and did not feature in the new Netflix documentary on the case.

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.
