Silver MacBook Pro with blue case, missing

I lost my silver MacBook Pro (13-inch) with a bright blue Speck case yesterday around 3pm. It was in my tote bag outside the Purdue Memorial Union on State Street, near the main entrance by the coffee shop before I headed to class. The lid has a panda sticker and a little cat sticker, plus there's a coffee ring near the trackpad. It still powers on, but the charger isn't in the bag. This laptop holds all my class notes and work files, so I'd be really worried about it; it's basically my lifeline for this term. If anyone found it, I'd be incredibly grateful to get it back.
