2022 University of Idaho killings
The two surviving roommates had returned home by 1:00am, and were in their beds on the ground floor of the home at the time of the murders. They were not attacked or held hostage, and did not awaken until later that morning. The four victims were stabbed to death on the second and third floors in the home, where they had been sleeping. The victims were not gagged or restrained, and the walls at the scene were splattered with blood.
