A woman charged with stabbing her two young children to death and severely injuring her father was arrested in Atlanta early Tuesday, nearly a week after the attack, authorities said.

Police had been looking for Felicia Williams since Wednesday, when officers following a 911 call found the bodies of her children, Elexis Nicole Hill, 9, and James Ross Hill, 4, in Williams' home in Bethlehem, a tiny town in northeast Georgia. Williams' father was found injured in the home, authorities said.

Williams, 26, was charged Friday with murder and aggravated assault.

Atlanta police, following an anonymous tip, arrested her around 1 a.m. Tuesday after finding her hiding in a closet in an Atlanta apartment, police said in a statement.

She was turned over to Barrow County authorities to face charges. Bethlehem is 40 miles northeast of Atlanta.

Williams' children were buried less than 24 hours before her arrest. During the ceremony, the children's grandmother had made an appeal during the funeral for her daughter to turn herself in.
