So, we are looking for something from the police to confirm that the chipper is no longer a lead? Like this?

snipped
detectives with the Burke County Sheriff's Office said that is no longer a solid lead.
and this is the article about it being a hit on the engine only and coming possibly from a cut.
snipped
that the hit was not on the wood chipper itself but the engine, and the blood could have come from a cut on a workers hand.

So, you have them saying it's not a solid lead. You have them saying it could come from a cut. AND you have them saying the dog only hit on the engine, not the chipper. I'm not sure what else is needed to discount this?
