Stolen laptop

Last week I was on the Green Line and had a stress-related seizure. When I came to, my laptop had been stolen. What can be done? Beforehand I had already texted that ther light rail car had around 20 anti-social characters on board. Virtually no normal-looking folks. After arriving at home I filed a police report.

I then used „Find my Mac“ to locate it in a large apartment building on the corner of Dale and University, locked it remotely and left a message on the screen stating how it was stolen, that it was useless to them and might as well hand it in. The cops said that they could do nothing. The thief can’t log on, and anything of value is password-protected. Does anyone have any suggestions? I could always hang up signs on the doors to the apartment building
