Missing: Mira Patel, 12, pink windbreaker, Roanoke

I lost my sister, Mira Patel, last night around 9pm after we left the Roanoke City Market Building. She was wearing a pink windbreaker, size 12 youth, gray leggings, and bright pink sneakers, and she had a blue backpack with a panda patch. She's about 4'9" tall, with shoulder-length dark brown hair tied in a loose ponytail, and a small star-shaped birthmark on her left wrist. I’m absolutely terrified and keep calling her name, walking the Market Street area, Center in the Square, and around the alleys behind the festival grounds, but I haven’t seen her. If anyone saw a girl matching this description in Roanoke—please let me know right away; she’s all I care about right now.
