The roads and waterways were busy, but aside from at least one water-related death, Hall County ended the July Fourth holiday on a relatively quiet note.

Marring the holiday was a swimming incident in which two people — a 24-year-old woman and 6-year-old boy — were taken to separate hospitals after they failed to resurface.

The woman, who was taken to Northeast Georgia Medical Center, died at 6:30 a.m. Monday, said Robin Hill, spokesperson for the Department of Natural Resources.

“Ngoc Minh Vo was trying to help (the) child who slipped off a float,” said Hill. “She was resuscitated at the site and had a heart beat before being transported to the medical center.”

Vo was reportedly in grave condition prior to dying from complications of the accident that occurred on Sunday.

David Kimbrell, Hall County fire chief said he believed the boy, whose face was blue when Gwinnett County rescuers found him, should be fine.

The boy was taken to Children’s Healthcare of Atlanta at Egleston, where he was placed in a hyperbaric chamber, equipment used to administer oxygen at elevated pressures.

The treatment should work “to shorten his recovery time,” Kimbrell said.

The woman and boy were part of a larger family gathering that had stopped in a boat near a sandbar off Van Pugh South Park in West Hall.

Family members were swimming in the area when the woman failed to resurface.

Across the state, the Department of Public Safety far underestimated the number of wrecks that would take place during the reporting, which began at 6 p.m. Thursday and ended at midnight Sunday.

The agency predicted 1,874 crashes, but there were 2,490 crashes overall that resulted in 682 injuries and 20 deaths.

July Fourth festivities at Laurel Park were busy but calm, said Cpl. Jeff Strickland, Hall County Sheriff’s Office spokesman, on Monday.

“There was heavy traffic, but we kept it moving smoothly,” he said.

Also on Saturday night, “we had some fireworks disturbances, but nothing major,” Strickland said.
