The two sisters, 13-year-old Christina Quires and 6-year-old Rhianna McBean were found Sunday afternoon. Police say the girls spent the night in a nearby park.
Officials say the girls do not appear to be injured.
Both girls were last seen in the area around Willow Street on Saturday night.
"She's a 6-year-old, she's a little girl. She's probably hungry, I don't know, I can't explain it," said the missing girls' mother, Nicolar Hoilett.
Police responded in full force. They flooded the neighborhood, going door-to-door and passing out flyers. The county called in a bloodhound to help. A helicopter circled the area for much of Sunday afternoon.
