Location history not available. How to find it?

I was on vacation, and today that I returned, I saw in my email a notification from "Find my iphone" app that my stolen ipad was found. Nonetheless, the ipad was tracked by the app 2 days ago, and apparently now it will not show me the location it was found.

Considering that my ipad was stolen among other things when the thieves entered my house, I need to see the exact location so that I can report it to the police. Is there any way to find the location it was turned on two days ago?
