DNA extracted from the glove is now undergoing analysis. Investigators are awaiting final lab confirmation before uploading the unknown male DNA profile into CoDIS, the FBI’s national database, where it can be compared against DNA collected in felony cases and missing persons investigations nationwide.
The FBI described the discovery as a significant development. A first step in processing DNA evidence is running it through criminal databases to determine whether it matches a known offender.
Authorities may also turn to investigative genetic genealogy — a technique that has helped crack cold cases in recent years.
This method allows law enforcement to submit DNA evidence to third-party DNA mapping services used by the public. Even if a suspect has never submitted DNA, a relative might have, potentially narrowing down an identity through family connections.
Familial DNA played a key role in the case of Bryan Kohberger, who was convicted of killing four Idaho college students.
Former FBI agent Jonathan Gilliam said the glove could be pivotal. “They can run that through the FBI CoDIS, which is basically a program that takes all felonies or people who’ve committed crimes that are felonious in nature, and they have their DNA taken — that gets into this program along with missing persons,” he said.
“As soon as that’s through, it’s going to take no time for that. I mean, that computer system can start working rapidly. If there’s a match within that database, then identification of the individual will be almost instantaneous once they make that connection,” revealed Gilliam.
