Convicted killer Bryan Kohberger was spotted with fingernail-type scratches across his face and wounds on his knuckles around the time that he murdered four Idaho students in a brutal attack - but brushed the injuries off as a car accident.

A teaching assistant and fellow criminology student at Washington State University told investigators he had noticed the injuries on the 30-year-old killer’s face and hands on two separate occasions around October and November 2022, new police records show.

One of the injuries was a large scratch on Kohberger's face which the student, whose name was redacted, described as looking like fingernail scratches, the records show.

When he asked Kohberger what had happened to him, he claimed he had been in a car accident.

It was around that time that Kohberger murdered Madison Mogen, Kaylee Goncalves, both 21, Xana Kernodle and Ethan Chapin, both 20.
