Four people were shot at Northpark Elementary in San Bernardino, California this morning. Police believe it was a domestic violence situation.

Maria Garcia, a spokeswoman for San Bernardino City Unified, said:

“We have a shooter down and three victims. One of them is a teacher, the other two are unknown, and their condition is unknown. We believe the situation is contained.”

San Bernardino was the site of a terrorist attack in December, 2015. Most likely because of that, local officials were quick to release information regarding this shooting and contain the situation.

Students have been evacuated to a nearby elementary school.

Fox 11 Los Angeles reports that the two victims who were transported to the hospital are in critical condition.

This story is developing. More details will be added as they become available.
