CUMMING — Four of the eight Forsyth County Sheriff’s deputies involved in the June 6 gunfight outside the courthouse in downtown Cumming returned to work Wednesday.

Sheriff’s Maj. Rick Doyle said the deputies, whose names have not been released are back on regular duty after being placed on administrative leave immediately after the shooting, which is standard procedure in such cases.

The four who have not yet returned are “still in the process of completing interviews and are expected to return soon.”

The deputies returned fire on 48-year-old gunman Dennis Ronald Marx of Cumming as he began what authorities have described as a “full frontal assault” on the courthouse.

Marx, who died of gunshot wounds, used explosives and other weapons in an attempt to enter the building and possibly take hostages.

Sheriff Duane Piper has credited a ninth deputy, veteran Daniel Rush, with preventing a “major catastrophe” by engaging Marx after he pulled a rented sport utility vehicle up the curb and onto the courthouse plaza. Rush slowed Marx enough for other deputies to get into position.

As of Thursday, Rush remained hospitalized, recovering from two surgeries to his right leg, where he was shot by Marx.

Marx was due to appear in court to enter a plea on drug and weapon charges from August 2011.

Instead, he launched the attack outside the courthouse. Despite bullet holes and broken glass, the courthouse reopened Monday morning after repairs were made over the weekend.
