DNA evidence in the killing of JonBenét Ramsey does not support a former prosecutor’s decision to clear the girl’s relatives in her death, according to an explosive new report revealing new information to the public for the first time in the 1996 killing.

A joint report by the Boulder Daily Camera and 9NEWS analyzed exclusively obtained lab test results and reports in the homicide that remains Colorado’s most closely followed unsolved murder two decades after the 6-year-old beauty queen was found dead in the basement of her family’s home.

Forensic experts who examined those DNA 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, which Lacy asserted when clearing the girl’s family of suspicion in 2008.

But the evidence, experts told the Boulder Daily Camera and 9NEWS, revealed that the DNA samples recovered from the long johns came from at least two people in addition to JonBenét. That’s something Lacy’s office was told, according to documents obtained by the news organizations, but a fact that Lacy did not mention when clearing the Ramseys.

The existence of a third person’s genetic markers has never previously been publicly revealed, according to the report, which also raised the possibility that the original DNA sample recovered from JonBenét’s underwear could be a composite and not from a single individual.
