On October 1, 2015, a school shooting occurred at the Umpqua Community College campus near Roseburg, Oregon, United States. Christopher Sean Harper-Mercer, a 26-year-old who was enrolled at the school, fatally shot an assistant professor and eight students in a classroom, and injured eight others. Roseburg police detectives responded to the incident and engaged Harper-Mercer in a brief shootout. After being wounded, he died by suicide, shooting himself in the head.
