BOULDER COUNTY, Colo. (KDVR) — It has been 25 years since JonBenét Ramsey was found dead. Her murder is considered by many to be one of the most notorious cold cases.

Now there is a renewed effort to find the person responsible for her murder.

JonBenét’s father and half-brother are petitioning Gov. Jared Polis to hand over the DNA samples the Boulder Police Department has collected and allow a company called Parabon NanoLabs to do DNA testing in the case.

JonBenét’s father, John Ramsey, spoke about the effort to find his daughter’s killer in an interview with 60 Minutes Australia on Sunday.

“We want to do whatever can be done technically and resource-wise to find the killer of our daughter and if we do that and we can’t, then we will have to live with it. But to not do it is criminal and negligent and lazy,” John Ramsey said.

A Parabon scientist said it could take just a few hours to identify DNA collected from the crime scene of JonBenét’s murder.

“So, it’s like a big puzzle. We have to put all the puzzle pieces back together, little by little by little. What I’m doing all day long is building the family trees of these individuals that are sharing DNA with this unknown suspect,” Parabon’s CeCe Moore said.

John Andrew Ramsey, JonBenét’s half-brother, sent out a tweet on Monday morning after the 60 Minutes interview.

“Hi– Gov. Polis. Parabon and CeCe Moore is the premier shop in the world to successfully hunt child killers. Let’s get to work.” John Andrew Ramsey shared.

There is currently a petition for “Justice for JonBenét” with over 11,000 signatures.

“JonBenét Ramsey deserves justice and new advances in DNA technology finally make that possible. Colorado Gov. Jared Polis, you are the only person with enough power and independence in the state to put Ramsey DNA testing decisions in the hands of a new agency that’s free from Boulder’s significant history with the case,” the petition creator shared.

“Hello Friends of JBR, just a quick note to let you know that the Governor’s office responded a couple of weeks ago to a request for an update with the following: “We do not have an update at this time.”

The 6-year-old was found dead in the basement of her Boulder home on Dec. 26, 1996, after her family reportedly found a ransom note inside the home. An autopsy revealed Ramsey was strangled to death.

As of Dec. 2021, the Boulder Police Department said they processed more than 1,500 pieces of evidence related to the murder of Ramsey.

At that time, the Boulder Police Department said “it was actively reviewing genetic DNA testing processes to see if those can be applied to this case moving forward.” BPD said nearly 1,000 DNA samples have been analyzed.

In 2019, Burke Ramsey, the brother of JonBenét, reached an undisclosed settlement in a $750 million lawsuit against CBS. The lawsuit said that Burke Ramsey’s reputation was ruined after a television series suggested he killed JonBenét.

In 2008, then-Boulder County District Attorney Mary Lacy wrote a letter to John Ramsey, JonBenét’s dad, saying new DNA evidence had cleared him, his wife and son. She formally apologized for the cloud of suspicion the Ramsey’s lived under for years.

“We believe at this point it is unlikely there will ever be a prosecution,” Boulder police said in 2008

Ramsey’s mom, Patsy, died of ovarian cancer in 2006.
