A 7-year-old Sugar Hill boy remained in a coma Wednesday, his family said, three days after a two-vehicle wreck that injured four other people east of Cumming.

Brandi Tudury said her son, Brody, was flown to Children's Healthcare of Atlanta at Scottish Rite Hospital, where he is in serious condition. She said the child, a student at Sycamore Elementary in Buford, is off a ventilator and breathing on his own, but has not awakened.

The Sunday afternoon collision on Hwy. 20 (Buford Highway) at Sanders Road threw Tudury's 14-year-old daughter, Brittani, from the vehicle.

The Lanier Middle School student broke her hand, leg and wrist and suffered several deep cuts, among other injuries.

She was released Wednesday from Scottish Rite, her mother said, and soon will begin using walker to walk.

"It was very fortunate we didn't have a fatality in this wreck," said Forsyth County Sheriff's Capt. Frank Huggins.

Huggins said Christopher Lafferty, 36, of Carey, N.C., was cited for running a red light in the incident, which occurred about 4:12 p.m.

It appears Lafferty was heading west on Buford Highway in his 2003 Honda Accord when he broadsided a 2000 Ford Focus driven by Tudury, 33.

Huggins said Lafferty struck Tudury's left rear passenger door.

"We don't know why he ran the red light," Huggins said.

He said both Tudury and her daughter were first taken to North Fulton Regional Hospital, where the mother was treated for a cut to the head and released.

Huggins said the teenager was sitting in the left back seat of the vehicle.

"The investigation at this point indicates everyone was wearing seat belts," Huggins said. "But (Brittani) was ejected."

Tudury's son, Huggins said, was "in the right rear passenger seat in a child seat and he was unconscious."

Tudury's mother, 59-year-old Mae Sullivan-Pettyjohn of Sugar Hill, also was injured.

Sullivan-Pettyjohn said Wednesday that she suffered a fractured vertebrae/broken neck. She was treated at North Fulton and released after three days.

Lafferty was not injured, though Huggins said the man's 12-year-old daughter, Hannah, was treated at Northside Hospital-Forsyth and released.

Two other passengers in Lafferty's vehicle did not report any injuries.

Linda Dowling and her 17-year-old daughter were behind Tudury waiting for the traffic light to change. She said it appeared that Lafferty was unaware of the light.

"We were looking and we could see the car coming very fast and my daughter said, 'He's going to run the red light. He's going to run the red light'," Dowling said. "And as soon as she said it the second time, bam, he did."

Dowling said Lafferty looked shocked when he realized he was about to hit Tudury's car.

"I remember seeing his face when they impacted and it was just awful," she said. "After it happened, everybody just kind of froze ... when they hit, the cars slid and swerved a little bit."

Huggins said the westbound lanes of Buford Highway were shut down for about an hour and 45 minutes Sunday as a result of the wreck.

Tudury said her family is grateful for the caring and compassion and "everything that was done for us" at the scene, thanking the sheriff's deputies, paramedics, witnesses and bystanders who helped.
