Kohberger is facing four counts of first-degree murder and one count of felony burglary in connection with the killings of four University of Idaho students.
A former graduate-school classmate of Bryan Kohberger said that the accused killer went "completely silent" during the class discussion of the killings.
""I m confident that Moscow Police Department, Idaho State Police and the FBI have the right person and I thank them from the very bottom of my heart," said Alivea Goncalves.
