I'm not saying they wouldn't solve it if they could. I'm saying they are not going to devote any substantial amount of time to trying to solve a 40 year old case. So the press conference, when they finally get around it having it, will just be a big show like Buckskin Girl was. Then they will have some drinks in a bar afterword, and then they will go back to working on current cases, and forget about it. There will never be any follow up, unfortunately.
