Framed landscape painting with gold frame

I lost my framed landscape painting yesterday around 3pm near the Riverfront Park gazebo on Garrison Ave, Fort Smith. It's a 16x20 inch acrylic on canvas with a black-to-gold frame that has a small dent on the lower edge and a tiny scratch on the top corner. The painting is signed 'L. Chen' in the lower right, with a faint fingerprint under the varnish from when I last handled it. It means a lot to me—it's a gift from my late mother, and I really need it back. If anyone found it, I’d be eternally grateful to get it home.
