Investigators said Kenyetta Clark was reported missing by her family the day after Christmas.
So far, efforts by her family and police to find her have come up empty.
Clark is a 15-year-old eighth grader at Lufkin Road Middle School.
Her mother, Valerie Tate, gave her permission to spend the night at a friend's house last Friday night after an evening at the roller skating rink on Trawick Road.
However, at some point between Friday and Saturday, Kenyetta disappeared.
Her mom had two brief phone conversations with her daughter on Saturday, but Tate said the second phone call was very bizarre. She said Kenyetta sounded distracted, and refused to tell her mother where she was.
Now, there's no answer on Kenyetta's cell phone, and most alarming to her mom, the girl's Facebook account has been deleted.
Police do not suspect foul play, but they are on the lookout for the girl.
Meanwhile, Tate is frantic.
"I just don't know what to do. I've done everything I know how to do. I've put up flyers," said Tate. "I've reached out to all her friends. I've knocked on doors. I've done everything I know how to do."
Tate does not believe her daughter ran away. She thinks Kenyetta is in a situation that "she can't get out of."
Clark is about 5' 1" tall and 100 pounds.
Anyone with information about Kenyetta's whereabouts is asked to call the Raleigh police tip line at (919) 834-HELP.
