Not everyone agrees, but I wish we could at least know how it was "resolved".
Well to be honest there has never been any solid evidence that this was ever a case to begin with. The photo was found over three decades ago and nothing has ever come of it other than Tara Calico's mom thinking it possibly could have been her daughter in the photo. If this photo was never attached to the Calico case it likely would have been forgotten about weeks to months after it was reported.
Nobody else has come forward claiming that they think the girl could be their missing daughter (which you think would happen if the kids in the photo were legitimately missing individuals. No one outside of Michael Henley's family (whose remains were found about a year after the photo was taken just a couple miles away from where he disappeared) has come forward claiming the boy looks like their missing son.
When you really think about it unless someone has the belief that the girl in the photo is indeed Tara Calico there is basically zero evidence that the kids were even missing at all.
