Bryan Kohberger was investigated in connection with an armed break-in one year before he fatally stabbed four University of Idaho students. According to Pullman Police Department records obtained by NBC News, authorities investigated a 2021 break-in at a home in Pullman, Washington, just across the state line from Moscow, Idaho. A knife-wielding masked individual allegedly broke into a house of four sorority sisters at 3:30 a.m. and stood over one of their beds, according to documents released by the City of Pullman.
