The still-grieving father, 78, announced on Saturday, April 30, he is petitioning Governor Jared Polis for permission to allow an independent agency to DNA test several items from the infamous crime scene, since the Boulder Police Department has failed to do so.
"It's a petition to hopefully get the state of Colorado to intervene and have the items from the crime scene that could be tested for DNA that haven't been tested," John explained in an interview with Fox News Digital.
John went on to say he believes if the Colorado government realizes through the petition that there are a lot of people who want the testing to be done, he will be more likely to allow it.
"It's a cold case, and they don't call it a cold case, but it is for all intents and purposes a cold case," he continued. "Why they won't test the DNA samples that should be tested for DNA, I don't know. It's baffling."
JonBenét was only 6-years-old when she was reported missing from her Boulder, Colorado home in December of 1996. Her body was later discovered by her father in the family's basement that same day.
Following an autopsy, it was revealed the little girl died from both trauma to her head and strangulation, and her death was determined to be a homicide. No suspect has ever been convicted of her murder, causing it to be one of the most shocking and mysterious true crime cases of all time.
