CHEROKEE COUNTY, Ga. -- A young mother of two was killed late Sunday night in a suspected DUI crash in Cherokee County.

Amy Walker was a passenger in a Chevy Tahoe that left Hickory Flat Highway at Oakcrest Circle and rolled over. She apparently was not wearing a seat belt and was thrown from the vehicle. The driver and another passenger survived.

"She has two kids, two beautiful little girls," said friend Sara Johnson. "They won't get to see their mama again."

The driver of the Tahoe was given a field sobriety test and was taken into custody, according to witnesses.

All of the people in the SUV were drinking earlier at a Cherokee County Mexican restaurant, Johnson claims. She told WSB-TV Channel 2 she knew the driver was drunk.

"He was gone; pitcher after pitcher," according to Johnson. She urged Walker not to ride with him.

"I told her not to get in the car with them," she said.
