The grieving family of 21-year-old Kaylee Goncalves spent weeks waiting for an arrest in her killing. Since then, they and relatives of the three other University of Idaho students fatally stabbed on a late 2022 night in their off-campus home have endured a legal process punctuated by delay after delay.

Bryan Kohberger, the suspect in the University of Idaho killings is expected to plead guilty, according to victims' families. CBS News legal contributor Caroline Polisi explains what it means for sentencing and justice.
