I think that is a common misconception. I see that exact same thing posted on every cold case thread on Websleuths, over and over again. If it was true, they would all be getting solved. I can't think of even one case solved with nothing more than publicity. Missy Bevers, crazy publicity, the case went 100% cold. Sherri Papini, crazy publicity, fortunately she survived but they case went cold. I could go on and on. Publicity does not solve cases. The only thing that solves cases is good detective work, either by real detectives or by internet wannabes.
