Jason Dale Johnson, 33, was one of nine people killed in the mass shooting at Umpqua Community College in Roseburg, Oregon, on October 1, 2015. The attacker, Christopher Sean Harper-Mercer, a 26-year-old student, entered Snyder Hall and targeted Classroom 15 during morning English and writing classes. Harper-Mercer carried two handguns, a Glock 19 and a Taurus PT24/7, and forced students into the center of the room before shooting; he spared one student to deliver a package to police and made that student witness the scene.

Roseburg police officers in plainclothes arrived about six minutes after the first 9-1-1 call and exchanged fire with Harper-Mercer, striking him once in the right side. After retreating into the classroom, he died by a self-inflicted gunshot wound to the head. Eight other students and an assistant professor also died; eight more students were injured. The community later organized support for victims and families, including a GoFundMe for injured student Chris Mintz that raised over $650,000.
