Missing child: 11-year-old Mia Thompson, pink backpack

I lost my daughter, Mia Thompson, yesterday around 4:30pm. She's eleven, about 4 feet 9 inches with curly black hair and olive skin. She was wearing a red hoodie with a white star, blue jeans, and bright pink backpack with a small unicorn keychain. She has a tiny heart-shaped birthmark on her left cheek and wears a silver bracelet with a heart charm. Last seen near the Battleground Avenue and Lawndale Drive intersection in Greensboro, NC, near the gas station by the corner, then heading toward the Four Seasons Town Centre. I am really worried—she's shy and tends to follow directions from strangers, so if you see her please message me here and I will meet you right away. She might be nervous and lonely; any info helps.
