Investigative genetic genealogy is at the center of the University of Idaho Murders. We're talking of course about the brutal

quadruple homicide of students Kaly Gonsalves, Madison Logan, Zenicernodal, and Ethan Chatebinn in 2022.

Defendant Brian Kohberger, a former criminology PhD student,

stands accused of stabbing the four victims to death in a house in Moscow, Idaho.

On the prosecution side of things, IGG appears to have helped bring Koberger onto the radar.

At the crime scene, investigators discovered a knife sheath that had

DNA on it. They used investigative genetic genealogy to trace the DNA straight

back to Coburger. In December of 2022, investigators secured garbage

from the Coburger family residents in Albright'sville, Pennsylvania. Tests uncovered

COBurger's father's DNA in the trash, which was a familial match to the DNA on the knife sheath.

But the defense has also been quite focused on IGG.

Filing from the defense team, led by attorney Anne Taylor,

have included numerous requests to receive all of the information

on the IGG that was done to help identify COBurger.

Now, the defense has complained in filings that they need all of the IGE workups.

The prosecution, on the other hand, has retorted that the IGG materials amount to a tip that led to a breakthrough and that they won't be using any of it in court.

So what's going on here?

To help us break down the topic of IGG in the Idaho case specifically, we're proud to bring

on two experts. Ignite DNA founders Nancy Lendini and Lisa Needler. These two investigative genetic

genealogists both receive graduate certificates for forensic genetic

genealogy from the University of New Haven, and they've also both
