Xana Kernodle was a 20-year-old University of Idaho junior studying marketing when she was killed in the pre-dawn hours of November 13, 2022, in an off-campus rental home on King Road in Moscow, Idaho. She and her boyfriend, 20-year-old Ethan Chapin, were staying on the third floor with roommates Madison Mogen and Kaylee Goncalves; all four were stabbed to death in an attack investigators estimate lasted about 25 minutes. Two roommates on the first floor were unharmed, apparently asleep during the incident.

Autopsy findings show Xana suffered numerous stab wounds, many of them defensive, indicating she fought back. A military-style knife and a sheath left at the scene produced DNA evidence and other investigative leads. Authorities later arrested 28-year-old Bryan Christopher Kohberger in Pennsylvania and charged him with four counts of first-degree murder and burglary. Prosecutors initially sought the death penalty; Kohberger ultimately pleaded guilty on July 2, 2025, and received four consecutive life sentences without parole plus 10 years. The motive for the killings has not been made public.

Did anyone who knew Xana, her social circle at the university, or the neighborhood notice anything unusual in the days before November 13, 2022?
