Brown leather briefcase with red interior

I found a brown leather briefcase this afternoon around 3:15 pm in the parking lot behind the downtown Gainesville Public Library on East University Avenue in North Central Florida. It’s a mid-sized case, about 14 inches wide, with a red interior that’s visible when you unzip the flap. The leather is a bit worn with a small scuff on the front corner, and there’s a brass nameplate inside engraved 'M. Carter.' Inside the front pocket I also found a faded coffee ring and a business card for M. Carter, Attorney at Law. I’d really like to get it back to its owner and I’m hoping the owner will see this and reach out through the app.
