FIND LAST LOCATION SENT

I NEED HELP- HOW TO FIND THE LAST REPORTED LOCATION OF AN IPHONE BEFORE THE BATTERY DIED.

THE PHONE HAS THE OPTION TO "SEND LAST LOCATION". WHERE DO I GO ON THE INTERNET TO FIND THE LAST LOCATION BECAUSE THE *FIND MY IPHONE* WEBSITE DOES NOT SAY ANYTHING ABOUT THE "LAST LOCATION". THERE IS NO "LAST LOCATION" OPTION TO SELECT. IF THE DEVICE IS OFFLINE IS THERE NO WAY TO FIND ANY LOCATION INFORMATION???
