Forsyth County sheriff’s volunteer killed while directing parade traffic
A sheriff’s volunteer with 21 years in law enforcement was struck in a coned-off parade zone in Cumming, then died hours later at North Fulton Medical Center.
A Forsyth County sheriff’s volunteer who spent decades in law enforcement was struck and killed while directing traffic at the City of Cumming Christmas parade, turning a routine crowd-control assignment into a fatal roadside tragedy.
Robert Muth was hit at about 7:19 p.m. Saturday, Dec. 13, 2025, at Castleberry Road and Buford Dam Road in Cumming, officials said. He was taken to North Fulton Hospital, later identified as North Fulton Medical Center, and died early Sunday morning, Dec. 14, 2025.
The City of Cumming Police Department said the driver remained at the scene and cooperated with investigators. Authorities identified the driver as 68-year-old Ronnie Jake Kirby, who was booked into the Forsyth County Jail on charges including second-degree vehicular homicide, improper lane change, failure to obey a traffic control device and failure to use due care.
Reports from the scene said the parade corridor was still coned off when a vehicle drove into the restricted area and struck Muth. That detail has sharpened the public-safety focus around the crash, because it places the collision in a controlled zone where volunteers and officers were working to keep spectators and traffic separated.
Muth was not just a parade volunteer. The Forsyth County Sheriff’s Office described him as a former employee and active volunteer, and local reports said he had served 21 years as a sergeant with the Boca Raton Police Department before coming to Forsyth County. After retiring, he worked as a Bluecoat security officer in the sheriff’s office Judicial Operations Division from January 2022 until April 2024, then volunteered with the Citizens Helping in Policing, or CHIP, unit and assisted with interoffice communications.
The sheriff’s office and the City of Cumming issued condolences after his death, and deputies and civilians later lined the road near the Forsyth County Courthouse for a roadside salute on Monday, Dec. 15, 2025. Officials said Muth left behind a wife and three adult children.
For Forsyth County, the loss reaches beyond one family and one parade route. It underscores how much local events depend on volunteer traffic control, and how quickly a split-second failure in a coned-off lane can turn a civic celebration into a fatal crash.
