Stolen iphone, have the address of who took it?

Hello so yesterday at school my phone was stolen, not even 30 mintues after i tracked it down, and watched it for another 2 hours and it stayed at the same location. ( i have the exact address) the person left school/ checked out right after nutrition, so it should be easy to narrow down who took it. But sadly its offline now. On Monday ( since the police werent there on friday), i'm making a police report, and i have the address, and since i know this person was gone after period one, whether they were truent or checked out i should be able to find them. The concern is it says offline now, i HAVE A PASSWORD, but i heard even if they took the sims card out can i still track it? I'm jsut worried about my privacy.

You can only track the Iphone if it is connected to the Internet. 3g 4g or Wi-Fi. If you are unable to find it the best thing to do is https://www.icloud.com/....com/#find Sign into your ITunes account and in the top left side you will see Devices click on your Iphone then a box pops up on the right click on Erase Iphone. Then the very next time it comes online it will Erase everthing.
