Late last month, Colorado police revealed that DNA found in slain JonBenét Ramsey’s underwear has not been tested through forensic genealogical methods.

The slain 6-year-old’s father, John Ramsey, meets with Boulder police once a year to be updated on his daughter’s case. John Ramsey learned during the most recent meeting that degraded DNA recovered from his daughter’s underwear could not undergo genealogy testing because the technology is not advanced enough, according to The Denver Gazette.

Boulder police are reportedly keeping abreast of developments with genealogy testing in case this changes.

“It’s not if but when,” John Ramsey told The Denver Gazette.

The publication noted that this was the first time police publicly disclosed that the unidentified DNA was not tested to establish a genealogical profile.

In 1996, JonBenét Ramsey was found bludgeoned and strangled in the basement of her Boulder home hours after she was reported missing and a ransom note was discovered at her residence.

John Ramsey has pressed Boulder police to retest evidence with updated genetic technology to obtain new leads in their daughter’s unsolved murder. He also urged the FBI to make child murder a federal crime — allowing the agency to automatically intervene in cases involving children 12 and younger.

Specifically, John Ramsey wants investigators to test external male DNA that federal authorities disclosed in 1997.

“That’s an important meeting. We’re going to have a representative with us for one of these cutting-edge labs to explain what they can and can’t do. Hopefully, he will accept their help,” he told Fox last year, referring to a meeting he was to have with Boulder police in December.

No arrests have been made in the 1996 slaying. The slain girl’s mother, Patsy Ramsey, died of ovarian cancer in 2006.

Anyone with information regarding JonBenét Ramsey’s murder should call or email the Boulder Police Department at 303-441-1974 or BouldersMostWanted@bouldercolorado.gov.
