Jonathan Martinez

The shooting, which San Bernardino Police Chief Jarrod Burguan said was a murder-suicide, happened shortly before 10:30 a.m. inside a special-needs classroom at North Park Elementary School in the 5300 block of North H Street.

Police identified the gunman as Cedric Anderson, 53, of Riverside.

They say he entered the classroom and, without saying a word, shot and killed his estranged wife, Karen Elaine Smith, 53. They had only been married a few months and were estranged for about a month, Burguan said.

It was not immediately known how many shots he fired, but the weapon, a .357 revolver, typically carries six rounds and he reloaded once before turning the gun on himself, Burguan said.

Two students were behind Smith and struck by gunfire. Both were airlifted to Loma Linda University Medical Center.

One student, identified as Jonathan Martinez, 8, died before making it to surgery, officials said. The other student, a 9-year-old, was in stable condition in the hospital.
