I honestly think the photo of the girl and the boy in the van with the stripy cushions is a hoax. For one thing the girl has her hands behind her as if they are tied, but if you look closely I do not think they are tied. I think normally if someones hands are tied they are tied palm to palm, or maybe back to back behind the victims back. In that case when the victim is lying down they will have an odd posture as their back will be raised due to the way their hands are tied. This girl is not at all raised, and her arms look too relaxed to be tied, so I think she has just shoved her hands under her back to make it look like they are tied for the photo. She also looks really ticked off, and the little boy looks like he is leaning into the photo, rather than them both being tired, and frightened. there are also no bruises, their eyes do not look swollen or puffy from crying, they both look healthy too. I also do not see what the point is of the photo. Why take a photo of people you have kidnapped? On the other hand why stage such a weird hoax? It might not even of course have meant to be a hoax - perhaps the two children are siblings with their parents, and after the kids had been rowing or something the parents as a joke put tape on their mouths for a minute and took a photo (hence the sulky look of the girl), and then never came forward as they realised it was in really bad taste. I know that seems far fetched, but you never know. I know I may be very wrong, but there is just something false about the photo.
As for tara. I really hope they find her, this is one of those cases that makes me angry. She was a nice hardworking girl, with a great future and someone stole it from her, and let her loved ones suffer until in her mother's case they died. Its just evil. I think that it was someone fairly local, and she was buried there. I know it is odd that no-one spoke for so long, but look at the huge number of murders and disappearences that remain unsolved. Someone knows what happened in each and everyone of these cases, yet has never spoken.
In the moors murders cases in 1960s Britin I think they sent a plane over the moors to photograph it so they could look for any disturbances, it is a shame they could not have done something similar for Tara in the desert when she disappeared. I hope they find her, she does not deserve to be left in an unmarked grave unknown to those who love her.
