LIVE Press Conference - after school shooting in Georgia

Four people were gunned down and several others injured at a Georgia High school Wednesday morning, sending shock waves through the leafy Atlanta suburb of Winder, Georgia, and schools throughout the county into lockdown.

Nine people were taken to hospitals with injuries, according to the Georgia Bureau of Investigation. The bureau also said a suspect was alive and in custody.

Calls about an active shooting at Apalachee High School started coming in around 9:30 a.m., Barrow County Sheriff Jud Smith said.

"This is a very, very fluid investigation," Smith said in a news conference, adding that officials would give more information at 4 p.m.
