I think the point is that at least three houses on Wellesley have been in the papers showing sniffer dogs entering, police doing forensics, Libby's parents entering etc, but no one is 100% sure which one of those is Libby's. No single house has been clarified by multiple MSM or, more importantly, LE as certainly being Libby's address. As such, no one in this thread can with complete factual certainty state that they know which house is Libby's.
We know so little and that is difficult to accept really. .
