But the latest date seems kind of meaningless, since it could have been put there before the 16th, an indeterminable time before the 16th. This means that it could have been there on the 16th, or it could have been there on the 2nd, right? So I don't see how this testimony help DW at all. It just means that the body wasn't dumped after the 16th-18th of Feb.
But what about before this? And what about after he got home but before the cops started surveiling him? It seems like the Bug Guy's testimony still leaves these times in question.
I don't disagree, but Feldman got Faulkner to say that he only saw one generation of flies, which could support a conclusion that the body was disposed of around 2/16-18.
The real key is that there were no beetle larva in/on the body. This is what establishes the no earlier than date after a time that DW could have disposed of the body.
