Found red-eared slider turtle near Riverfront Park

I found a red-eared slider turtle this afternoon around 2:45pm near Riverfront Park along the Ohio River in the Parkersburg-Marietta area. It's about 4 inches long, with a bright green shell peppered with yellow speckles and a distinct red stripe behind each eye. The shell shows a tiny crescent-shaped scar on the left rear scute, and one tiny chip at the edge of the plastron. It seemed active, alert, and hungry but I didn’t want to keep it. If this is your pet or you know who it belongs to, I’m happy to hold onto it or arrange a safe drop-off near the Blennerhassett Ferry dock.
