A criminology graduate student, Bryan Christopher Kohberger, has been arrested and charged with first-degree murder in the killings of four University of Idaho students. Kohberger was arrested in Pennsylvania and is being held for extradition to Idaho, where he will face four counts of first-degree murder and felony burglary charges. The four students were found stabbed to death in their beds in an off-campus residence near university sorority and fraternity houses. The quadruple killing caused fear and mistrust among residents, as no suspect was named for weeks. The motive for the killings is still being investigated. Kohberger is a PhD student at Washington State University.
