Incident Summary:

10/01/2015: An assailant, identified as Christopher Harper-Mercer, entered a classroom at Umpqua Community College and held an unknown number of students and staff hostage in Roseburg, Oregon, United States. Armed with six firearms, the assailant shot and killed nine people and injured at least seven others. He exchanged fire with responding police officers before shooting and killing himself.
