Whoever duct-taped JonBenet Ramsey’s mouth shut, bludgeoned the 6-year-old Colorado girl and strangled the child beauty queen in her own home has evaded capture for almost 28 years.

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.

It’s been almost 30 years since JonBenét Ramsey was found murdered in the basement of her family’s Colorado home.

As Netflix's Cold Case explored the tragic death of JonBenét Ramsey, renewed interest in the thirty-year-old mystery has taken shape.

I truly believe this is one of the most brutalized families in American history,” says Joe Berlinger of the late Patsy, John and Burke Ramsey, who have all been accused in the 1996 murder of the 6-year-old pageant queen.

Eight hours later, John Ramsey discovered JonBenét’s body in the basement. She was found with duct tape over her mouth and a nylon cord tied around her wrists and neck. In a move that further compromised the crime scene, John carried his daughter’s body upstairs, removing her from the location where she had been found.

JonBenét Ramsey was murdered when she was 6 years old. Find out about the pageant queen's brothers, John Andrew and Burke 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.

Amid renewed interest in the killing of JonBenét Ramsey triggered in part by a new Netflix documentary, police in Boulder, Colo., refuted assertions this week that there is viable evidence and leads about the 1996 killing of the six-year-old girl that they are not pursuing.

The infamous murder investigation — which remains open nearly three decades later — is explored in Netflix's 'Cold Case: Who Killed JonBenét Ramsey.'
