A gunman has killed at least three people and wounded six in a shooting at a Georgia high school.
Police say the suspect opened fire before officers arrived.
More from the Associated Press: The gunman, who was shot and killed by a police officer, was believed to be a student at Glynnwood High School.
He was identified by school district officials as 17-year-old Jonathan Allen.
Police Chief Robert L. Boyd said the suspect was identified as Allen by family members, who identified him by his first name, Allen.
Authorities say Allen was on campus at the time of the shooting.
The school district says he had a “significant and prolonged mental health problem.”
In a statement released Friday evening, the district says it is “deeply saddened” by the loss of life and “heartbroken” by Allen’s actions.
The district says “this is an extremely sad and tragic day for the people of Georgia and the entire Georgia community.”
More from AP: “It is clear that these young men were not acting in self-defense and were simply acting in a desperate effort to protect themselves and others,” Boyd said in a statement.
“This incident has caused a tremendous amount of grief and grief and loss for the victims and their families.”
The superintendent of the district said the shooter acted in self defense, but did not provide further details.
The district says the suspect is now in custody.
“We are grateful for the quick response of law enforcement officers,” Georgia State Police Superintendent Robert Lacey said in an interview with the Associated.
Lacey said officers are searching for the shooter.
Police have not said if the suspect will face charges.
Glynnwood Superintendent Mark DeBruin said he was “deepestly saddened to learn of the tragic events that occurred at our school today.”
“Our thoughts and prayers are with the families of the victims of this tragedy, and our thoughts and prayer are with all our students and staff,” he said in the statement.
Students and staff from Glynn-Wood Elementary School and a nearby middle school were evacuated and students were told to stay home from classes Friday, a school official told the Associated news agency.
Officials have not identified any victims.
