I guess nobody told the cops, but plumbers have gone high tech since then. I can reach a snake with a video camera down that hopper and search the pipe right up to the point it hits the public main.
Anything between the hopper and the main is guranteed to come from that house. And I promise you, with a good snake, you WILL be able to retrieve evidence.
But hey, we're here to play Rambo, not roto rooter. How effin sexy is that?
