School shooter in Monterrey has died of wounds

Mexican authorities announced that the 15-year-old student that opened fire at a private school in the northern Mexican city of Monterrey on Wednesday morning has died of wounds.

The teen, suffering from depression, injured three students and a teacher and then he shot himself. 

A school video showed the male middle-school student first shot the 24-year-old teacher, then shot a 14-year-old girl and a 14-year-old boy in the head, and a 15-year-old classmate in the arm. He then pointed the gun at classmates before shooting himself in the head. 

Nuevo León state Gov. Jaime Rodríguez said three victims with head wounds were "fighting between life and death." The boy wounded in the arm was out of danger.
