Without speaking, Anderson opened fire on Smith with a large-caliber revolver. She died at the scene. Anderson then turned the gun on himself, Burguan said.

Two students who happened to be standing behind Smith were struck by gunfire, Martinez and a 9-year-old boy.

“Cedric entered the classroom without saying anything, armed with a large-caliber revolver, opened fire on his wife,” Burguan said. “She was killed in that exchange. There are two students in the classroom that were behind the teacher that were struck by gunfire.”

Both boys were airlifted to Loma Linda University Medical Center. Martinez died at the hospital, Burguan confirmed. The other boy is stable. His name was not released.
