A teacher and three students were reportedly shot Wednesday at a private American school in northern Mexico, before the 15-year-old gunman turned the gun on himself.
NBC San Diego reports the shooting was at a school in Monterrey, Mexico. The shooter and his victims had bullet wounds and were in extremely serious condition.
A school video showed the student first shot a 24-year-old teacher, then 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.
Officials said the teen shooter had been suffering from depression, but his motive is under investigation.
