Wow some of you are pretty stobborn. This does happen. Just because you have corn in your area and just because you hanvn't heard of it before doen'st mean it doens't happen.

Deer during the winter after corn field are picked and are mostly gone, start getting into there winter diets. Buds of bushes, trees, accorns again. They start living off the forest again. Their enzymes and digestive systems start to get used to this. Then if they stumble uppon a huge pile of corn in someones back yard or in a feeder and fill there belly's full of corn and there stomach isn't used to digesting it, they can die! It happens! God you think people just make this stuff up fo the heck of it.
