Missing woman, 5 ft 6 in, black hair, blue jacket

I'm Rachel Kim, 28, 5 ft 6 in, about 140 pounds, with shoulder-length black hair. I disappeared yesterday around 3pm after leaving a coffee shop near Market Street by the Gateway Arch in downtown St Louis. I was last seen wearing a bright blue puffer jacket, dark jeans, and white sneakers. I have a crescent-moon tattoo on my left wrist and a silver hoop earring in my right ear. My family is really worried—this jacket was a gift from my grandmother, and I'm not sure what to do without it. If you see me or have any info, contact my sister at [email protected].
