Georgia Governor Brian Kemp urged residents to join him in prayer on Wednesday 4th September after an active shooter left multiple casualties at Apalachee High School.
The death toll is currently four, with nine others injured.
Colt Gray, 14, is in custody and it has been confirmed that he was a student at the school and was known to the FBI before the tragedy occurred.
According to Sky News, One of the school officers confronted Gray and he surrendered immediately.
Barrow County sheriff Jud Smith told the outlet: "The shooter quickly realised that if he did not give up, it would end with an OIS [officer-involved shooting]."
In a statement on X Brian Kemp wrote: "I have directed all available state resources to respond to the incident at Apalachee High School and urge all Georgians to join my family in praying for the safety of those in our classrooms, both in Barrow County and across the state.
"We will continue to work with local, state, and federal partners as we gather information and further respond to this situation."
