Police in Philadelphia are searching for two girls who disappeared during a trip to a nearby playground.
Taliya Hamilton, 14, and Brianna Boyd, 3, were last seen in the playground, about two blocks from their home, at about 8 p.m. Sunday night, MyFOXPhilly.com reported.
Police have searched the girls' home and local areas they've been known to frequent, a police spokesman told FOX News.
No Amber Alert has been issued because police don't have a reason to suspect a danger to the girls. But the length of time they have been missing is a concern, police said.
Michelle Hamilton, the girls' mother, told MyFOXPhilly she doesn't think a stranger abducted her children, noting that her older daughter recently became rebellious and has been running off for a day or two at a time.
"Taliya's just been walking off lately," Hamilton told the station. "I'm not even sure what's going through her mind right now. I don't know what possessed her to take Brianna with her. I mean, if she wanted to walk off or go somewhere, she could have Brianna back in the house or brought her back across the street."
Taliya Hamilton was described as 5 feet 6 inches tall, about 115 pounds, with brown eyes and brown, straight hair down to the middle of her back. She was last seen wearing a gray sweatshirt, blue jeans and white sneakers.
Her sister is 3 feet 4 inches, about 30 pounds, with brown eyes and short, curly black hair. She was wearing a red and black jacket, black pants, black sneakers and had different colored barrettes in hair.
Anyone with information is asked to contact the Philadelphia Police Department.
