Milo Chen, 12, missing near Riverside Park

I lost my 12-year-old son Milo Chen yesterday around 3pm near Riverside Park in downtown La Crosse. He's about 4'10", slender, wearing a bright blue windbreaker over a gray hoodie, dark jeans, and white sneakers. He has a small star-shaped pin on his backpack and a faint scar above his right eyebrow. Last I saw him by the park's gazebo near 4th Street and the riverfront trail. This is really hard—Milo carries a family photo in his pocket and it means a lot to us. If you see him, please call me right away; he might be scared and trying to find his way home.
