Missing teen: 16-year-old boy, red hoodie

I lost my little brother, Kai Patel, yesterday around 3pm. He was last seen near the Farmington Market District, by the corner of Main Street and Elm Lane, walking toward the old cinema. He's about 5'8", with black hair, wearing a gray puffer jacket under a red hoodie, dark jeans, and blue sneakers; he also has a compass tattoo on his right wrist and a silver stud in his left ear. This is really worrying—Kai has wandered off before, and if you spot him, please contact me right away; it's important we find him soon.
