Bryan Kohberger has admitted guilt in the slayings of four students at the University of Idaho. But the public still doesn't know what motivated Kohberger to commit the knife attacks and how he chose his victims in 2022.

Residents expressed a mix of relief and anger Tuesday in the small Idaho college town where four students were stabbed to death in 2022 after news that the man charged in the killings had agreed to plead guilty to avoid a trial and a possible death penalty.
