Two years ago, a 2-year-old boy died after the parked car in which he was sleeping was hit during a chain-reaction wreck in Atlanta.

Wednesday, the driver charged in the crash tearfully pleaded no contest and was told that she will serve two years in prison, Channel 2 Action News reported.

Driver Kelly Canty, 21, couldn't stop crying during the hearing at the Fulton County Courthouse, and the proceedings were briefly stopped.

"Everybody makes mistakes and I don't want my life to be thrown away for an accident that I have caused, but I'm very, very sorry for everything," Canty said, according to Channel 2.

On June 1, 2010, Canty's car crossed the yellow line on Donald Lee Hollowell Parkway and hit a tractor trailer, police said. The tractor trailer, trying to avoid another collision, jumped a curb and ended up hitting three cars in the AutoZone parking lot.

Zion Curney was killed, and his cousin was injured.

Canty was charged with first-degree vehicular homicide, reckless driving, failure to maintain lane, and driving without a license or insurance.

The judge ordered Canty's 15-year sentence commuted to time served, plus two years.

Canty, who was sentenced under Georgia's First Offender Act, is being allowed a few weeks to arrange for the care of her two children before turning herself in to begin her prison time.

"This is something she'll have to face the rest of her life," Zion's mother, Chiquita Curney, said. "I think she's been sentenced to life with the memory of my son's accident."
