Kyron Horman comes to mind; they have used odd phrases about "a different lens" etc...and have never named a POI. While many have concluded on their own that Terri Horman is guilty, LE never mentions her and seems to be stuck, per their own words, without any physical evidence and not knowing if he dead or alive after all this time.
I don't know much about that case, but I did believe Terri Horman was guilty from the beginning myself. I haven't followed this case, so wasn't aware about LE, but this is an interesting case to look at for me because it seems to be in line with what you are claiming.
