On Friday, authorities filed more charges against the teens.
Davis is now charged with assault with a deadly weapon inflicting serious injury and Covington faces additional charges of felony breaking and entering, felony larceny and possession of a stolen vehicle.
Both had already been charged with robbery with a dangerous weapon, conspiracy and larceny of a motor vehicle.
Taylor told ABC11 on Monday that she was trying to be a good neighbor and tell the boys about a dog she had seen run through her yard.
"I turned to show them where it was," she explained. "When I turned my back, they attacked me.
Investigators say that's when Covington struck her on the back of the head with a brick.
"When they knocked me to the ground, I was laying on the ground," she said. "I didn't know what they were going to do -- maybe kill me."
Taylor fell to the ground and Covington continued to kick and beat her, demanding that she give him her car keys. She told the teens her keys were inside her house on the kitchen counter.
Deputies say Davis and Covington left with Taylor's car and drove around with friends until police stopped them at a nearby fast food restaurant.
When police stopped the teens, there were two other friends in the car. They told the officer they were cruising.
Taylor was taken to Cape Fear Valley Medical Center where she was treated for a head wound.
Davis and Covington are being held in the Cumberland County Detention Center under a $100,000 bond.
