A woman critically injured in a Friday night golf cart accident at a private campaign event for 9th District U.S. Rep. Tom Graves has died.

The woman, whose name could not be verified, died Monday afternoon, said Hall County Coroner Marion Merck.

Merck said the woman died at the Atlanta Medical Center where she was airlifted after the 7:30 p.m. accident. He said he was unsure about details of her injuries or whether there are pending toxicology reports.

“She died in Atlanta and we have to get all our information from Atlanta,” he said.

The accident occurred at a home in the 3700 block of Harbour Point subdivision where about 100 supporters of Graves gathered for an event.

The woman was among five people being shuttled to the event when the cart’s brakes failed on a steep hill, witnesses said. The cart crashed into some vehicles, spun and overturned. At least three other people were injured.

Graves supporter and a witness to the accident, Mark Marlowe, 68, said the cart driver sideswiped some parked cars to make the cart stop instead of careening to the bottom on the hill at 35 mph.

The passengers were ejected from the cart, and Marlowe said he broke a shoulder bone.

Besides Marlowe, two other people were taken by ambulance to Northeast Georgia Medical Center. One woman, a Graves campaign employee, remained hospitalized there on Saturday, but further information on the injured was not available Monday night.

Graves campaign manager, Tim Baker, said Graves’ wife, Julie, led supporters in a prayer for the crash victims, and the event ended when emergency vehicles left the scene. Marlowe told The Times that Graves spend most of Friday night at Northeast Georgia Medical Center checking on the injured.
