Following the murders, Bryan Kohberger, a former criminology graduate student, was arrested and convicted.
In July 2025, Bryan pleaded guilty to the four murders and received four consecutive life sentences without the possibility of parole – therefore avoiding the death penalty.

Prime Video's series explores the various theories surrounding his motive, including his criminology background and alleged ties to online incel communities, as well as the major role social media sleuths played throughout the case and the impact this had on the families involved.
