The DNA evidence in the murder of JonBenét Ramsey does not support a former prosecutor’s decision to clear the girl’s relatives in her death, according to a new report.

The Boulder Daily Camera and Denver television station KUSA analyzed lab test results and reports in the unsolved murder two decades after the 6-year-old beauty contestant was found dead in the basement of her family's home.

Forensic experts who examined those tests disputed former District Attorney Mary Lacy's conclusion that a DNA profile found in one location on the girl's underpants and two spots on her long johns necessarily belonged to the killer. An outside laboratory found genetic markers from two people in Ramsey's clothing, Reuters reported.

That's something Lacy's office was told, according to documents obtained by the news organizations, but did not mention when clearing the Ramseys in 2008.

The existence of a third person’s genetic markers has never previously been publicly revealed, according to the report.

The beaten and strangled body of JonBenet Ramsey was found in the basement of her parents’ Boulder, Colorado, home on Dec. 26, 1996. No one has been charged with her killing.

In 1999, a grand jury voted to indict JonBenet's parents, John Patsy and Patsy Ramsey, for child abuse resulting in death, but then-District Attorney Alex Hunter declined to prosecute, citing a lack of evidence.

Patsy Ramsey died in June 2006 after battling ovarian cancer for more than a decade.
