A University of Idaho graduate student recalled an alleged “awkward” conversation and “peculiar” subsequent text she received from Bryan Kohberger in 2022, months before the Idaho murders.

(CNN) — Bryan Kohberger, the former criminology grad student accused of killing four University of Idaho students in November 2022, appeared in court Thursday morning in one of the last pretrial hearings before the start of his much-anticipated trial.

The identity of the alternate suspect named by Kohberger and the evidence his defense team claims links this person to the grisly killings remain a mystery.
