I can't help but wonder if maybe they shouldn't rethink their "waiting" because if I had to take a gander at it, I would say that KYRON has probably BEEN ready to have his family plea to his adbuctor (if that is what happened) or at least plead to anyone who may know any information to come forward NOW.....while it IS useful to the case??!!!
I'm sure if police felt it would be really useful to the case to have the family going on camera making pleas, they'd be doing it. I don't think it usually does any good at all -- just makes the family feel like they're doing something to try to find the child.
There are obviously some complicated family issues here, and that may be part of the reason the family is staying out of the media (with the exception of the stepmother's mother, who did quite a bit of yakking early on). Kyron disappeared while in the custody of his father and stepmother, with the stepmother being the last to see him. Meanwhile, the biological mother, for reasons we don't know, lost or gave up primary custody of Kyron when he was an infant, which is quite unusual.
Even more unusual is that the stepmother has been Kyron's primary mother since before she was actually married to his father. And that the stepmother's own biological son doesn't live with her or with his biological father, but rather with his mother's parents. And Kyron's biological mother obviously wants to stay closely involved in Kyron's life, since she sees him every other week. So she may be (speculating here, on account of her not having had custody of him since he was infant) a bit unstable, possibly with a drug abuse or criminal history (remember the tidbit from the stepgrandmother that Kyron is "afraid of police") or mental health issues, and furious with the stepmother for "losing my son". If the stepmother and father go on camera, the biological mother would likely be eager to follow and might be very difficult to stop if she was really angry. Nobody needs family drama sprawled in the media, unless there's reason to believe it could actually aid in finding Kyron. Waiting for the family to be "ready" to speak publicly may be a euphemism for waiting for them to calm down and stop screaming at each other.
Given what we know about all the layers of biological parents and stepparents and somewhat unusual custody arrangements, even if they're all wonderful people, there's got to be some serious stress and conflict between the various parties in a situation like this. I would assume some stress and conflict in a complex family like this, even in the best of times, with no missing child emergency to fan the flames.
