MEXICO CITY (AA) – A 15-year-old student died after injuring four people in a shooting at an American school in Monterrey, according to authorities.

Officials said Federico Guevara opened fire on a teacher and two classmates before he shot himself in the chin at the Colegio Americano del Noreste.

Nuevo Leon Gov. Jaime Rodriguez said the gunman died from brain damage after he was taken to a hospital.

''The young man is already dead, but we must investigate the reasons for the shooting and help the families touched by the event'', Rodriguez said.

Rodriguez said that four ''seriously injured'' victims were shot in the head while a fifth person sustain minor injuries. All victims have been taken to a hospital.

Guevara, recently showed signs of depression, according to sources with knowledge of the shooting, Mexican media reported.

"I join with the pain and dismay of families and the school community,” President Enrique Pena Nieto said via Twitter.

Nuevo Leon state security spokesman Aldo Fasci qualified the event as “unprecedented,” given that shootings at Mexican schools are rare but he suggested the Internet played a role in the shooting.

"The children have access to the Internet. This is the result of a situation that is happening everywhere and seen everywhere," he said while standing in front of the school.

Previous policies that allowed school authorities to check students’ backpacks were discontinued after opposition from parents, Fasci said.
