My iphone was stolen last night?

Added (1). I have the find my iphone app on my phone and it showed me a location last night, but today its saying my phone is offline and can't give me a new location. What does it mean by offline? And how can I get it online so I can track it?
My phone is in lost mode.

The person that stole it most likely turned on airplane mode and turned off Wi-Fi. That means there in no internet connection. Report the iPhone to Apple As soon as possible and try to get the serial code. The person that stole tge device probably also reset the iPhone but if you had iCloud (you have 5gb free with your apple ID) you can get pictures and apps back using the same spple ID. Make sure to remove any cerdit/debit cards from your apple ID and report it to the police.

They turned it off because they know that you are looking for it. Keep trying. They will turn it on sometime to try and play with it or reset it. Beat them to it. If no luck, then call your carrier and report it as stolen so they will brick the device. Best luck.

It's probably turned off or ran out of battery call apple and report it stolen

Lock it and put it in lost mode. You can't get it online.
