Oh man. I had something like this happen once. Came home one day to find a deer standing in my driveway. I knew something was wrong and as I got closer, I realized it had been hit by a car. It was in really bad shape. I seriously thought about putting the poor thing out of its misery but I didn’t get time to do anything before it took off into the woods behind my house.

About three days later, I walked out my front door to the most God awful smell imaginable. I thought I was going to be sick. The deer had run just past the tree line and promptly collapsed and died right there in the woods behind my house. I couldn’t go outside for a week.

Based on the “size” of the smell, that’s what I’m thinking is the culprit here. There’s all kinds of suburban deer around, and if I’m right, there may be one less now.
