AURORA, Colo. (KDVR) – Aurora students will not be allowed to leave campus during lunch starting Monday, Aurora Public Schools (APS) Principal Rico Munn said on Saturday.

The new campus closure policy follows two recent shootings involving students during lunchtime. It will be in effect until the Christmas break.

The announcement came during a public prayer vigil organized by the APS in Nome Park, the same spot where six students at Aurora Central High School were injured in a drive-by shooting on November 15.

Four days later, on November 19, three students were gunned down in the parking lot of Hinkley High School, about 10 minutes from Nome Park.

Two teenagers, both 15, were arrested in connection with the Nome Park drive-by shooting.

Three teenagers, all 16, face attempted murder charges in connection with the Hinkley High School shooting.

After high school students were involved in two shootings over the course of a school week, Aurora Police Chief Vanessa Wilson pleaded for parents to keep a more vigilant eye on their children.

“It’s our kids shooting each other,” Wilson said at a press conference on Nov. 19. “We have a lack of respect and no concern for life. I need parents to get involved. I need you to check the phones, I need you to check the rooms, I need you to check the cars and make sure they take those guns from these kids.
