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.

JonBenét Ramsey, who competed in beauty pageants, was found dead in the basement of her family's home in the college town of Boulder the day after Christmas in 1996. Her body was found several hours after her mother called 911 to say her daughter was missing and a ransom note had been left behind. The details of the crime and video footage of JonBenét competing in pageants propelled the case into one of the highest-profile mysteries in the United States.

The police comments came as part of their annual update on the investigation, a month before the 28th anniversary of her killing. Police said they released it a little earlier due to the increased attention on the case, apparently referring to the three-part Netflix series Cold Case: Who Killed JonBenét Ramsey.

In a video statement, Boulder Police Chief Steve Redfearn said the department welcomes news coverage and documentaries about the killing of JonBenét, who would have been 34 this year, as a way to generate possible new leads. He said the department is committed to solving the case, but needs to be careful about what it shares about the investigation to protect a possible future prosecution.

"What I can tell you, though, is we have thoroughly investigated multiple people as suspects throughout the years and we continue to be open-minded about what occurred as we investigate the tips that come into detectives," he said.

Cold case gets renewed attention with new doc

The Netflix documentary focuses on the mistakes made by police and the "media circus" surrounding the case.  

JonBenét was bludgeoned and strangled. Her death was ruled a homicide, but nobody was ever prosecuted for it.

Police were widely criticized for mishandling the early investigation into her death amid speculation that her family was responsible. However, a prosecutor cleared her parents, John and Patsy Ramsey, and brother Burke in 2008 based on new DNA evidence from JonBenét's clothing that pointed to the involvement of an "unexplained third party" in her slaying.

The announcement by former district attorney Mary Lacy came two years after Patsy Ramsey died of cancer. Lacy called the Ramseys "victims of this crime."

John Ramsey has continued to speak out for the case to be solved. 

In 2022, he supported an online petition asking Colorado's governor to intervene in the investigation by putting an outside agency in charge of DNA testing in the case. In the Netflix documentary, he said he has been advocating for several items that have not been prepared for DNA testing to be tested and for other items to be retested. He said the results should be put through a genealogy database.

In recent years, investigators have identified suspects in unsolved cases by comparing DNA profiles from crime scenes and to DNA testing results shared online by people researching their family trees.

In 2021, police said in their annual update that DNA hadn't been ruled out to help solve the case, and in 2022 noted that some evidence could be "consumed" if DNA testing is done on it.

Last year, police said they had convened a panel of outside experts to review the investigation to give recommendations and determine if updated technologies or forensic testing might produce new leads. In the latest update, Redfearn said that review had ended but that police continue to work through and evaluate a "lengthy list of recommendations" from the panel.
