The spine will drop a deer in it's tracks, even from a bow however, it's not necessarily a fatal shot and a follow up shot is usually necessary. You should opt for a quick human kill.

The shot you should be shooting for is a double lung shot. Please check out www.kerrlake.com/deer/white2.htm for pictures of deer anatomy. Again, pick a hair and double lung them.
