Idaho student killer Bryan Kohberger posed around his Washington State University apartment making faces at his phone camera, creepy newly released selfies show.

Wearing cordless headphones and standing in front of a closet full of blue shirts, the bare-chested Kohberger salutes the camera in a selfie, showing a cut on one of his knuckles.

In another, he’s making a contorted face, revealing a row of yellow teeth as he grins.

“He takes his shirt off, flexes his muscles, and takes a picture of himself, and then just goes back to whatever he was doing before,” he told Fox News Digital. “Nonsense.”

While the Barnharts did not have the authority to share the photos, they described them as “narcissistic” and strange. He even took photos at bizarre angles, highlighting himself from behind and in profile.

Kohberger pleaded guilty to four counts of first-degree murder and one of felony burglary last month.

He is serving four-consecutive life sentences, plus another 10 years, for the murders of University of Idaho students Xana Kernodle, 20, Ethan Chapin, 20, Kaylee Goncalves, 21, and Madison Mogen, 21.

The plea deal required him to waive his right to appeal and his right to seek a sentence reduction.
