They could have brought Lanza in the back door in one of those large garbage bins on wheels already "processed", and dumped him on the floor for all anyone knows. I find that equally as plausible. Was the guy running in the woods part of it, and botched the exit strategy? Don't know yet.

Why are they putting kooky contrived witnesses on TV...is it rush to get a story out, or something else?

NY times outed the one guy who claimed he was his uncle as a fraud, which sparked the police to put out a statement warning anyone who tries the same. They are supposed to be interviewing credible background checked witnesses. This is the least to be expected.

Do they want to lose viewership credibility on purpose over rushing a story out with flaky, suspicious witnesses, I don't know the answer to that yet.
