Almost three decades after JonBenét Ramsey was murdered, new methods for extracting usable DNA from limited or deteriorated samples could open up fresh investigative possibilities, according to a forensic expert.
The investigation began in December 1996, after six-year-old JonBenét Ramsey was discovered dead in the basement of her family’s home in Boulder, Colorado.
An autopsy later concluded that JonBenét died from asphyxia resulting from strangulation, in combination with craniocerebral trauma. Her death was officially ruled a homicide.
Despite a lengthy investigation and years of intense public attention, nobody has ever been charged with her murder.
“DNA is incredibly complex”
Now, certified forensic technician and crime analyst Cassie Leigh tells UNILAD that new technology could provide crucial new insights into the case.
“DNA is incredibly complex, which is both a blessing and a curse for investigators,” Leigh said, according to the outlet. “When a sufficient, high-quality sample is available, the odds of two unrelated people sharing the same DNA profile are practically impossible.”
“With newer DNA technology, investigators may now be able to develop useful genetic profiles from samples that previously would have been difficult to analyze.”

She explained that these methods could help investigators trace “familial connections, rather than relying solely on traditional law enforcement DNA databases'”
“In a case like JonBenét’s, that could potentially open up entirely new investigative leads, provided the available evidence is suitable for this type of testing,” she said.
Traditional forensic DNA testing looks at specific repeating patterns in a person’s DNA. SNP testing works differently by examining tiny genetic variations at hundreds of thousands of locations.
She described it as “looking for tiny spelling differences in an incredibly long instruction manual.”
What is Forensic genetic genealogy?
Forensic genetic genealogy uses DNA from a crime scene to search for possible relatives of an unidentified person.
“The Golden State Killer case is probably the most famous example of forensic genetic genealogy helping solve a decades-old criminal investigation,” she said.
However, the method does have limitations. “It isn’t a magic fix for every sample, esppecially when DNA from multiple people is mixed together,” she added.
Limited resources and the small amount of DNA available can also make the process more difficult. And even if investigators find a genetic match, that does not automatically mean they have identified the perpetrator.
“Familial DNA matches don’t automatically identify someone as a suspect, much less prove they committed a crime,” she said.
