I have a funny story similar to yours.
One time my parents came home from their nightly walk at dusk and they said that there was a deer that had just got hit down the road. So, we went to go check it out. It was laying on the side of the road alone, just looking at us, pretty obviously it couldn't run away or else it would have. The car that had hit it was nowhere in sight. We were actually petting it, it was the first time I had seen a deer so close. My dad calls his brother to see what he can do (since he is a hunter and has guns - we don't). Anyway, while he is on his way there, one of the neighbors down the street calls 911 to tell them about the deer. We tell her its just best to put it out of its misery - that because it isnt running away its pretty much gone. She comes up with some line about it will shit right before it dies, and it hasn't done that yet. This ambulance arrives, along with a police car. The neighbor lady tells the paramedics that she wants to reabilitate the deer at the little stable she has up the road. She is going on and on about how thy have to do something.. so they start to give this deer oxygen - this is the most ridiculous thing I have ever seen. At this point, it had caused quite a commotion and there were all these cars and ambulances and crap, and we were pissed off, so we just left. We heard that they had called animal control and they put it down. It was quite a sight.
Goes to show the weird crap that can happen in suburbia
