Bryan Kohberger stood silent in a Latah County courtroom Monday morning, when he was asked to make a plea in connection with the slayings of four University of Idaho students.

Consequently, a judge entered a not guilty plea on the Washington State University student’s behalf, during an arraignment hearing.

Prosecutors and defense attorneys agreed on an Oct. 2 trial date, the Idaho Statesman reported Monday. The trial is expected to last up to six weeks.

Kohberger faces first-degree murder charges in the slayings of Ethan Chapin, Kaylee Goncalves, Xana Kernodle and Madison Mogen, who were found stabbed to death in an off-campus house on Nov. 13.

A grand jury indicted Kohberger last week.
