The gunman continued to fire at Webb, who retreated to the garage. At one point the officer was lying near the "believed-to-be" deceased body of Sandra White as he and another officer attempted to escape the gunfire. 

Other officers went in to rescue Webb from the garage, according to Amerman.

Officer Keegan Merritt was shot in the hand as he attempted to set up the perimeter around the house. 

Amerman said the gunman fired "hundreds of rounds" at officers outside the home.

The negotiation

Amerman said they had no reason to believe that 16-year-old Arkeyvion White was dead, which is what led to the extended negotiation. When the negotiations failed, police ordered gas to be deployed in an effort to get Bailey outside of the home. 

Authorities had to wait a few hours for the chemicals to clear the house. When they entered the house, they discovered the bodies.

Officer update

Webb and Merritt are recovering at Grady Hospital with non-life-threatening injuries, according to Amerman. 

Capt. Joey Smith said Friday that both officers underwent surgery and are recovering; they could be released soon.

Amerman asked the public to pray for both the victim's family and the Henry Co. officers who were shot.
