The same day victims of a Nevada school shooting were remembered with a vigil, an 11 year old Washington boy was arrested for bringing a handgun, 400 rounds of ammunition and several knives to school.
And police in Indiana were readying themselves for a similar event.
At Rushville Consolidated High School in the small community of Rushville, about 50 miles southeast of Indianapolis, the sound of gunfire rang out.
Moments later the principal announces from the intercom in his office that there is an active shooter in the building.
Police, armed, make entry.
This is part of a training exercise to test the readiness of first responders in the event of a school shooting.
It's a first for Rushville's Police Department.
'These are not isolated incidents anymore,' explains Rushville Police Chief Craig Tucker. 'Unfortunately they are happening everywhere and we want to make sure we're prepared.'
Although the timing of this training exercise comes on the heels of the Nevada shooting, it's been in the planning stages for nearly a year. Ever since the Sandyhook Elementary massacre, where a former student shot twenty children and six staff members in Newtown, Conneticut.
More than 20 emergency agencies participated in the exercise at the Rushville High School, while students were on fall break.
Actors played victims shot and lying on the floor. Police had to overcome unexpected obstacles before taking down the gunman. Fire crews and Red Cross tended to the 'wounded'.
They all worked together to evacuate the school.
The training helps them figure out the line of communication among a large number of first responders.
Rushville Police Chief Craig Tucker says they conferred with dispatchers from the Sandy Hook incident and updated their own methods accordingly.
The directors of Rush County's Emergency Management Agency admitted when he began in emergency service nearly 30 years ago, this was not a scenario he ever believed he'd train for.
For communities in Indiana, and around the country, it's now a necessary and regular part of emergency preparedness.
