Bryan Kohberger's DNA matches Idaho crime scene evidence, prosecutors confirm.

DNA found on a knife sheath at the scene of a quadruple murder in Idaho last November matches a sample taken from suspect Bryan Kohberger, according to court documents. Kohberger was indicted on four counts of first-degree murder and one count of burglary in May. Law enforcement officials used investigative genetic genealogy to build a family tree of potential relatives of the suspect, and a comparison of the DNA samples revealed an overwhelming statistical match. Kohberger is being held without bail in Latah County, Idaho.
