Will JonBenét Ramsey’s killer finally be brought to justice 28 years after her murder? The upcoming Netflix docuseries “Cold Case: Who Killed JonBenét Ramsey” claims that authorities continue to mishandle the case of the death of the 6-year-old in 1996, including the not-so-subtle blame they placed on the family. Her father John remains confounded by the missteps, and in 2022, he spoke to Access Hollywood’s Zuri Hall what he considers their biggest mistake. “Cold Case: Who Killed JonBenét Ramey” hits Netflix on Nov. 25.
