From the moment he entered the courtroom for his long-awaited sentencing for the quadruple murders of four University of Idaho students, Bryan Kohberger projected what experts described as a cold, robotic presence. 

According to body language expert Susan Constantine, his frozen posture, sunken appearance, furrowed brows, and manic stare suggested a man attempting to control the courtroom with “covert hostility” masked as indifference.

His mask at times cracked in subtle ways as he was sentenced for the murders of Kaylee Goncalves, Ethan Chapin, Xana Kernodle and Madison Mogen and listened to the emotional victim impact statements.

Baden noted a shift in posture as Xana Kernodle’s aunt offered an olive branch in forgiving Kohberger and offering to talk.

“For the first time, Kohberger slumped slightly, exposing his stomach chains, perhaps revealing fatigue discomfort, or unacknowledged remorse,” Baden noted.
