Leopard gecko missing; orange with black speckles

I lost my orange leopard gecko yesterday around 3pm near the Canal Walk behind the City Market on Market Street in downtown Indianapolis. He's about 4 inches long, bright orange with black speckles, a thin white stripe along his spine, and a small nick on the tip of his tail. Geckos are skittish and like to hide under rocks, so I haven't seen him since, and I'm really worried he'll wander into a doorway or a store and get stepped on. It was a gift from my sister and has sentimental value to me; please help me get him back, if you spot him, text me here and I’ll come right away.
