Washington Post:

San Bernardino Police Chief Jarrod Burguan said during a news conference Monday that Karen Elaine Smith, 53, a teacher, was killed inside a classroom at North Park Elementary School by her estranged husband, Cedric Anderson, 53. Anderson died of a self-inflicted gunshot wound.

The chief said Jonathan Martinez, 8, was airlifted to a local hospital, where he died. Burguan said a 9-year-old child, whose name has not been released, remains in stable condition at a local hospital.

“I am told that both the students were behind the teacher when the suspect shot his wife,” Burguan said. “We have no reason to believe that the students were targeted, not that it makes it any better.”
