When a teenage student brought a gun into Troutdale, Oregon’s Reynolds High School on June 10, the carnage he could have caused was cut short by two armed resource officers who ran toward the sound of the shots.

The officers–Nick Thompson and Kyle Harris–closed in on the shooter’s proximity in “less than a minute.”

According to Oregon Live, “Troutdale Police Chief Scott Anderson credited the two resource officers… for preventing further carnage.” Said Anderson: “I believe their quick response saved many of our students’ lives.”

“At least one of the officers fired shots,” he added.
