Offline could mean any number of things. The battery ran down and it shut off. It simply has no data connection available. Someone found it and turned it off.
Find my iPhone is a handy feature sometimes, but it is by no means fullproof - no remote tracking system is.
If someone found it and turned it off, they can restore it as new in iTunes and that will wipe it clean, also making it untrackable from then on (since your iCloud account on it would be wiped off by the restore operation).
Sorry, but if it is offline, there is nothing you can do about it remotely.

I agree with Michael. Just go to www.icloud.com and put it in the Lost Mode.
