LOS ANGELES—Police in San Bernardino, California, sought more clues on Tuesday to the marital discord they believe led a gunman to walk into an elementary school class taught by his estranged wife and open fire, fatally shooting her and a student before killing himself.
Monday’s shooting at North Park Elementary, the latest of dozens of U.S. schools traumatized by armed intruders in recent years, left a second child badly wounded and reopened a debate about what educators can do to safeguard students against gun violence.
It was especially wrenching for the city of San Bernardino, the “Inland Empire” town about 65 miles east of Los Angeles where another shooting rampage 15 months ago left 14 people dead and more than 20 wounded at an office holiday party.
Unlike the 2015 massacre, carried out by a radicalized Muslim couple in what authorities described as an act of terrorism, police said the latest shooting apparently grew out of a domestic dispute between the suspect and his wife.
