Kohberger is expected in court on July 2 to plead guilty to the murders of four University of Idaho students in a deal to avoid the death penalty.

Bryan Kohberger is expected to plead guilty on Wednesday to all counts in the killings of four University of Idaho students, despite the former criminology student's initial eagerness to be exonerated in the high-profile case.

Idaho State Police contracted with Woodlands-based Othram to perform a genealogical analysis of a knife sheath found at the crime scene.
