They had originally stopped using cadaver dogs around Dec. 10th, (once they had finished the white, and middle class areas, coincidentally), they said they'd run out of money for it. They were ready to bulldoze, and only after alot of outrage did they ever bring back the cadaver dogs. That's why it's taken so many months for these bodies to be found.

There are alot of issues around race and class down there, so be prepared for that.
