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.

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.

New revelations in the JonBenét Ramsey case from Netflix's Cold Case docuseries, including the "bogus" ransom note and DNA evidence, reignite public interest.
