It was a dead squirel in my air conditioning closet outside of my house. Thank you so much to David with Casa Mechanical. He was here to do an annual AC check and I asked if he had any idea what the smell was, he knew it was a dead animal and found the squirrel after cutting into a couple of ducts. I am so happy the smell is gone. Here are a few pics for you to enjoy. This thing was nasty, covered with maggots and one side was completly rotted off. For the record, I reached in to the small hole and pulled this Mother Effer out. I am very brave.
