Missing person: 14-year-old boy in red hoodie

I lost my 14-year-old son yesterday around 3pm near the Charleston City Market on Market Street. He's wearing a bright red hoodie, blue jeans, and a green backpack with a cartoon fox patch. He's about 5'2", with short brown hair, round black-framed glasses, and a small birthmark on his left wrist. This is really scary for me—he's my only child and he doesn't respond well to crowds, so I'm worried and just want him back safe.
