Editing Killing of JonBenét Ramsey (section)

===Blood samples===
In December 2003, forensic investigators extracted enough material from a mixed blood sample found on JonBenét's underwear to establish a [[DNA]] profile.<ref>{{cite news |url=https://www.cbsnews.com/news/jonbenet-dna-rules-out-parents/ |work=CBS News |title=JonBenet: DNA Rules Out Parents |date=December 16, 2004 |access-date=July 16, 2006 |archive-date=November 3, 2013 |archive-url=https://web.archive.org/web/20131103203052/http://www.cbsnews.com/stories/2004/12/16/48hours/main661569.shtml |url-status=live}}</ref> That DNA belonged to an unknown male person, and excluded the DNA of each of the Ramseys. The DNA was submitted to the FBI's [[Combined DNA Index System]] (CODIS), a database containing more than 1.6 million DNA profiles, but the sample did not match any profile in the database.<ref name="DC Brennan" /> In October 2016, a report said that new forensic analysis with more sensitive techniques revealed that the original DNA contained genetic markers from two individuals other than JonBenét.<ref>{{cite news |url=https://www.reuters.com/article/us-crime-jonbenet-idUSKCN12T007 |work=Reuters |title=DNA cited to clear JonBenet Ramsey family in murder in question: report |date=October 28, 2016 |access-date=July 2, 2017 |archive-date=November 8, 2020 |archive-url=https://web.archive.org/web/20201108141851/https://www.reuters.com/article/us-crime-jonbenet-idUSKCN12T007 |url-status=live}}</ref><ref>{{cite news |url=http://www.dailycamera.com/news/jonbenet-ramsey/ci_30514220/jonbenet-ramsey-dna-evidence |work=Daily Camera |title=DNA in doubt: New analysis challenges DA's exoneration of Ramseys |date=October 27, 2016 |access-date=October 29, 2016 |archive-date=April 15, 2019 |archive-url=https://web.archive.org/web/20190415015754/http://www.dailycamera.com/news/jonbenet-ramsey/ci_30514220/jonbenet-ramsey-dna-evidence |url-status=live |url-access=subscription}}</ref>

A. James Kolar, who was a lead investigator for the DA's office, said that there were additional traces of male DNA found on the cord and paintbrush that Boulder district attorney Mary Lacy did not mention, and that there were six separate DNA samples belonging to unknown individuals that were found by the test.<ref name="Time Inc."/> Former FBI profiler Candice Delong believes that the DNA, having shown up identically in several different places on multiple surfaces, belongs to the killer.<ref>{{cite news |last1=Kieran |first1=Nicholson |title=Burke Ramsey hopes JonBenét murder investigation finds killer |url=https://www.denverpost.com/2016/09/19/burke-ramsey-hopes-jonbenet-murder-investigation-finds-killer/ |access-date=December 22, 2020 |work=[[The Denver Post]] |date=September 22, 2016 |archive-date=November 3, 2020 |archive-url=https://web.archive.org/web/20201103223759/https://www.denverpost.com/2016/09/19/burke-ramsey-hopes-jonbenet-murder-investigation-finds-killer/ |url-status=live}}</ref> Former Adams County, Colorado, District Attorney Bob Grant, who has assisted the Boulder DA's office on the case for many years, also believes that the DNA evidence is significant, saying that any resolution of the case would have to explain how the DNA showed up on several pieces of JonBenét's clothing.<ref name="DC Brennan" /> Forensic pathologist Michael Baden said, "Trace amounts of DNA can get on places and clothing from all different, nonsuspicious means. There is no forensic evidence to show that this is a stranger murder."<ref name="Time Inc."/>
