Two adults and an 8-year-old child are dead, and another child was wounded, in what is being called a murder-suicide at North Park Elementary School in San Bernardino. San Bernardino Police Chief Jarrod Burguan said Cedric Anderson, 53, of Riverside, came to the school shortly before 10:30 a.m. Monday and went to his wife’s classroom. Karen Elaine Smith, 53, was there with two aides and 15 special-needs students between first and fourth grades. The pair had been separated for several weeks, Burguan said. “Without saying anything, armed with a large caliber revolver, he opened fire on his wife,” Burguan said. “She was killed in the exchange.” Student Jonathan Martinez and another student, who has not been identified, were behind the teacher and were also shot. Jonathan was airlifted to Loma Linda University Medical Center, where he later died of his injuries. The second child, a 9-year-old boy, was in critical but stable condition as of Monday afternoon.
