While John and Patsy Ramsey were the highest-profile suspects in JonBenét Ramsey's murder, several others emerged through the years, including John Mark Karr.

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.

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