The man accused of shooting another man inside the Decatur Library has been granted immunity, dismissing the case.

Immunity granted

What we know:

A judge has officially dismissed all criminal charges against a man involved in a February shooting inside the Decatur branch of the DeKalb County Public Library after determining he acted in self-defense, according to court documents. 

Medicus Brown, 44, was granted immunity after a motions hearing earlier this month. Brown’s attorney argued that he was defending himself.

That has led to the case being dismissed.

The DeKalb County District Attorney's Office confirmed it will not appeal the ruling or pursue further charges, officially closing the case.
