DNA found on a knife sheath was at least 5.37 octillion times more likely to be Kohberger’s than that of an unrelated member of the public, prosecutors said in a court filing last week.

"Investigators first submitted DNA from the knife sheath — found facedown on a bed next to the bodies of Mogen and Goncalves, and partially under Mogen's body and the comforter — to the
FBI database CODIS, which tracks DNA profiles of people who have been arrested or convicted, according to the filing.
When that didn't turn up a match, investigators turned to genetic genealogy, commissioning a private lab to build a DNA profile that could be used to search for relatives, the filing states.
The FBI then took over and uploaded the DNA profile "to one or more publicly available genetic genealogy services to identify possible family members of the suspect based on shared genetic data," the filing states."
