Rear Defrost Drained Battery

On my way to work I had to use the rear defroster. Once I got to work and cut the car off, I noticed that the defroster button was still on. I tried pushing the button again and even pulled out the owner's guide to find out that there is a 15 min auto shutoff (although I thought the defroster would cut off once the car is cut off). Needless to say nothing worked because when I checked on the car at lunch the battery was drained.

Any thoughts?
