Authorities say a man was estranged from his wife before he shot and killed her in a special-needs classroom in San Bernardino in a murder-suicide that also left a student dead, the AP reports. Police Chief Jarrod Burguan said Monday at a news conference that 53-year-old Cedric Anderson and 53-year-old Karen Elaine Smith had only been married for a few months and estranged for at least a month. Smith was a teacher in the special-needs classroom for students in first through fourth grades where the shooting took place. An 8-year-old student was hit by gunfire and died, while a second 9-year-old boy was wounded and is in stable condition.
Burguan says "no one has come forward to say they saw this coming." Burguan also said Anderson had a criminal history of weapons charges, domestic violence, and possible drug charges but didn't provide details. Police say he said nothing and opened fire on his wife with a large-caliber revolver. The two children struck by gunfire were standing behind Smith. Police identified the boy who died as Jonathan Martinez. (Read more school shooting stories.)
