Full-size Yamaha violin in black case

I lost my full-size Yamaha violin in a black hard case yesterday around 3pm. It vanished somewhere in the Detroit Metro area, most recently near the Detroit Institute of Arts on Woodward Ave in Midtown Detroit after I grabbed a quick coffee at a cafe on Cass Ave. The violin is a warm amber color with a tiny dent on the chin rest and a brass fine tuner on the tailpiece. The bow has a red ribbon bow cover, and the case lining is a worn red satin. This instrument means a lot to me—it's been with me through years of lessons and performances, and I really need it back.
