The death of two Arizona girls at Independence High School in Glendale comes at an eerie time. 

The two were found dead just before 8 AM Friday morning under a covered patio area at the school. It has been reported as a murder-suicide after both girls were found dead from a single gunshot wound. The firearm was found near the bodies.

The timing is eerie given that Sue Klebold, the mother of one of the Columbine shooters, breaks her silence during a sit-down interview with Diane Sawyer that airs Friday night on 20/20. 

Klebold has not spoken since the 1999 incident that left 13 people and the two shooters dead. 

Kern County is not immune to school shootings.

In 2013, Bryan Oliver shot and critically injured a classmate at Taft Union High School. Oliver was later sentenced to 27 years in prison.

Joseph Lopeteguy, Chief of Police for Kern High School District, says that local schools are prepared if another shooting were to occur.

"I have to unfortunately plan for when, not if, and so are planning is based on that," said Lopeteguy.

"We try to stay one step ahead. The best way to solve something is, in a stress situation, habit takes over. If you develop good habits, you can become more successful in those situations then if you haven't."

Friday's shooting in Arizona is the 7th school shooting in 2016.
