Two students and two teachers were killed at a Georgia high school on Wednesday in a mass shooting authorities say was committed by a 14-year-old male student at the school.

At least nine others were taken to the hospital following the incident at Apalachee high school in Winder, about 50 miles north-east of Atlanta.

Officials said at an afternoon press conference that the suspect was alive and in custody, and surrendered quickly as officers, including two school resources officers, entered the campus and confronted him.

Chris Hosey, director of the Georgia bureau of investigation, took the unusual step of naming the minor, Colt Gray, as the suspect. He said the suspect would be charged as an adult with four counts of murder.
