Investigators want police to retest JonBenét Ramsey's DNA with new technology

The killer has never been found and the case has been left cold ever since.

There has been a growing push to retest DNA from the case with technology that investigators did not have before.

At the forefront of the discussion is JonBenét’s brother, John Andrew Ramsey.

He has recently put pressure on Colorado Governor Jared Polis to open up evidence from the case to allow a third-party agency to conduct new tests.

In Australia's version of 60 Minutes, Parabon's chief genetic genealogist CeCe Moore suggested that the company's methods could identify DNA from the crime scene in a matter of hours.

Cindy Smit-Marra—daughter of detective Lou Smit, who first proposed the ‘intruder theory’ that exonerated the Ramsey family—and investigator John Anderson have likewise been pressing Boulder police to look into re-testing.

Smit-Marra and Andersons’ efforts are being funded through a GoFundMe.

They're collaborating with a request the Ramsey family has made to Jared Polis to hand over the investigation from Boulder to a Parabon NanoLabs.

The pair said the Boulder PD was initially somewhat cooperative with their efforts, but turned cold once they revealed they were focusing on the theory that exonerates the Ramsey family.

Amid the discourse, Boulder Police have maintained that they are still testing and looking into the case.

"The Boulder Police Department regularly meets with multiple entities regarding this investigation, to include private labs, the FBI, CBI, the District Attorney's Office and others," the department wrote on social media in response to criticism.
