When the word lock-down comes into play thoughts of schools in crisis come to mind.
"Considering what just happened it just makes you all the more aware that it could hit at any time," said parent Stephanie Ridgdell.
What hit Sand Creek was a loss of temper.
An angry parent reportedly made threatening statements to the school's on duty police officer who recommended a level one lock-down, keeping kids and staff in, and everyone else out.
"This time since it was the lowest level nobody was really that scared, they were just like, yeah there's somebody walking around," said Ridgdell’s daughter Kayla.
But District 49 superintendent Dr. Nancy Wright says school policy is always better safe than sorry, especially in light of recent tragedy.
"I think there was a heightened sense of caution with students because of what's gone on around the country, particularly right here in Bailey, Colorado in last ten days," said Wright.
The angry parent never tried to get on to school grounds.
Aside from the cancellation of after-school activities, students felt little impact from a potential threat. A relief for parents, and the best possible way to end a lock-down.
Superintendent Wright said Springs police, staff and students handled Thursday’s lock-down perfectly. District officials will get together to review current emergency plans for effectiveness.
Wright said the district expects their students to improve, so the community should expect the same from the district.
