Jada Simelton, 15, was last seen Oct. 23 near her home.
Simelton is a Black female with black hair, brown eyes and light brown skin. At the time of her disappearance, her hair was long and braided.
"I can't even begin to imagine," said her father. "This is a parent's worst fear, especially when you didn't have a single sign."
Simelon's dad said she cleared her phone and her computer. He said Simelton left their home last Saturday while the family slept.
He has this message for her: "You have a whole village of people who love you and want you. Just come home."
She may have been wearing pink tie-dye leggings, a pink shirt and multi-colored Crocs when she went missing.
