JonBenét Ramsey’s father John Ramsey slammed the suggestion that her brother Burke, who was 9 years old at the time of her 1996 murder, had anything to do with it.

It was a story that gripped the country and one that has yet to be solved. In the early hours of Dec. 26, 1996, JonBenét Ramsey’s mother, Patsy, found a ransom note on the stairs of their Boulder, Colorado home saying JonBenét had been kidnapped.

Ramsey’s father, John, is still asking for police to investigate the case and find Ramsey’s murderer. He told The Today Show on Thursday, “There have been horrible failures… but I believe it can be solved if police accept help from outside their system. That’s been their flaw.”

The case garnered widespread attention, becoming an international story that critics say hurt the investigation to find who killed JonBenét Ramsey.

JonBenét's brother Burke Ramsey has kept a low profile even as Netflix's "Cold Case: Who Killed JonBenét Ramsey" reignites interest in the murder.
