Missing person: teen girl in red hoodie

I'm really worried—my sister Ava Patel, 15, has been missing since yesterday around 6:40 pm after we split up at the Walmart on Locust Street in Grand Island. Ava is about 5 ft 3 in with a slender build, shoulder-length black hair, and a small silver moon pendant that she never takes off. She was last seen wearing a bright red zip-up hoodie with a white star on the chest, faded blue jeans, and gray sneakers. She was walking toward Center Park from the parking lot. If you spot her, reach out through the app right away; I just want her back safe with us.
