Teacher & student killed in US elementary school shooting

A husband opened fire on his wife Monday in a San Bernardino elementary school classroom, killing her and a student in a murder-suicide that spread panic across a city still recovering emotionally from a terrorist attack at a community center just 15 months ago. The shooter also died, and a second student was critically wounded at North Park School. While most of the school's 600 students were quickly shepherded to safety, police announced hours later that one, an 8-year-old boy, died of his wounds.”I don't know what to do. I don't know what to tell her,” Elizabeth Barajas said after a tearful reunion with her 9-year-old daughter, Marissa Perez, who witnessed the shooting.
