A closed-door hearing transcript reveals defense attempts to challenge investigative genetic genealogy evidence in the University of Idaho quadruple murder case.
According to Fox News, Ada County Judge Steven Hippler has unsealed a 175-page partially redacted transcript from a January 23 hearing where Bryan Kohberger's defense team questioned the legitimacy of DNA evidence that led to his arrest.
The hearing focused on the defense's claims that the FBI potentially violated internal policies and database terms of service while conducting investigative genetic genealogy (IGG) searches.
Defense expert Dr. Leah Larkin testified that evidence suggested unauthorized access to genealogy databases, particularly noting the use of MyHeritage and GEDMatch without proper authorization.
Moscow Police Detective Brett Payne testified that the IGG information was treated as an investigative tip rather than primary evidence. The detective emphasized that additional evidence was gathered independently to establish Kohberger's connection to the murders of four University of Idaho students.
The DNA evidence centered around a knife sheath discovered under victim Madison Mogen's body. Initial attempts by Idaho State Police and Othram Laboratories to generate leads from the DNA sample were unsuccessful, leading to FBI involvement.
Detective Payne provided testimony stating that the FBI's contribution was handled similarly to other tips received during the investigation. He stated:
We made that decision in an effort to independently verify the information that was provided to us as a tip from the FBI, in much the same way we would any other tip in law enforcement. So it was not in any way meant to obfuscate any sort of information, it was simply can we validate Mr. Kohberger's involvement in this incident or can we not. That was it.
Defense expert Larkin raised significant concerns about the FBI's methodology. She testified that the number of DNA matches suggested unauthorized database access, explaining:
I believe we asked them to turn over the match lists, and they were like, oh, we can't turn over the whole match list because it was 20,000 people. And that, actually, right there was a big tip-off because if they had only used GEDMatch PRO and only used FamilyTreeDNA, I think at most they could have gotten to about 10,000. So that right there tipped me off that they were in a database that they should not have been able to be in.
The transcript revealed attempts to contact potential relatives identified through the genealogy search, including four brothers whose identities remain protected under a court order. One brother initially questioned the detective's legitimacy and later refused further contact.
Judge Hippler ultimately rejected the defense's motion to exclude the IGG evidence, determining that the FBI's actions did not violate Kohberger's constitutional rights under the Fourth Amendment.
The case has seen several developments since Kohberger's arrest at his parents' Pennsylvania home on December 30, 2022. His legal team successfully argued for a venue change, moving proceedings from Latah County to Ada County under Judge Hippler's jurisdiction.
The trial, scheduled to begin in August, is expected to last several weeks. Kohberger faces potential death penalty charges for the murders of Madison Mogen, 21, Kaylee Goncalves, 21, Xana Kernodle, 20, and Ethan Chapin, 20.
Bryan Kohberger remains in custody following his arrest for the November 13, 2022, murders of four University of Idaho students. The recently unsealed transcript provides insight into the defense's strategy to challenge DNA evidence that led to his identification as a suspect. While Judge Hippler has ruled against excluding the genetic genealogy evidence, the case continues to progress toward an August trial date where Kohberger faces capital murder charges.
