Black leather briefcase with brass hardware

I lost my black Samsonite leather briefcase yesterday around 3pm near the Springfield Public Library on Main Street. It's a full-grain black briefcase, about 18 inches wide, with brass zippers and a slightly worn handle. Inside there's a red spiral notebook, a USB drive, and my badge holder clipped to the top pocket. Look for the small dent on the lower-right corner and a frayed stitch along the left edge—the ground here is easy to spot. It has sentimental value because it held notes from my grandmother and important client materials, and I really need it back.
