Missing person: 14-year-old Maya Chen

I lost my sister, Maya Chen, yesterday around 7pm in Ames. She's 14 years old, about 5'2", with shoulder-length black hair and a small scar above her left eyebrow. Last seen near the North Grand Mall area and Frame's Coffee on Lincoln Way, wearing a bright red hoodie, a gray backpack, and white sneakers. She wears a pink bracelet with tiny charms that spell 'Hope' and often tucks her hair behind her ears. I'm really worried—she's usually cautious but gets overwhelmed in crowds. If you see her or have any information, please contact me directly; she might respond to 'Maya' or 'Little Chen' on her bracelet.
