Purdue Deer

So I know this is a couple of days late, but news is very slow for me now. Did anyone hear about the deer that got stuck in a window in a Purdue building? Apparently the window to a basement was half open and a deer crawled in. Some of the anesthesiologists had to go sedate the deer so they could try to get it out. Then apparently instead of going out, it went further in so it was loose in the basement! This is as far as I've heard in the story, but seriously what would make a deer try to enter a building in the first place?
