I think I've heard about this happening a couple of different times on the news. Here are some actual photos of it though. A deer jumped off (or was scared off by a passing card) an overpass bridge in Wayzata, MN and landed on a Durango that was driving under the bridge at the time. Suffice to say the deer died, the Durango SUV was brutally mangled, and the people in the Durango sustained minor injuries. Just look at how bent the steering wheel and column are.

Check out a higher resolution photo of the Durango destroyed by the deer and a second photo of the front of the Durango mangled by the deer.
