There is a great deal of frustration over this tragic case, probably stemming from several factors.
I personally feel that news outlets are not giving us enough, feeding off each other's reporting because they are hampered by the seemingly slow investigation, and the family members' choices—for whatever reasons—in releasing news and making public appearances. Of course, lack of information leads to speculation, and as time goes by, more of that can cloud real issues.
This crime, whether it is murder or kidnapping, seemed at the outset to be an easy investigation, with an obvious choice for a likely suspect. Then other factors entered the equation: a woefully inadequate school alert system and questions about who saw what at school, a family reluctant to talk to the public (or even talk to their missing child over the airwaves, very strange), and a sheriff's department that, forgive me, does not sound like it is being as aggressive, as it could be, making emotionally reassuring but not confidence-inspiring comments to the public. Further, it would seem the family of Kyron is making all the decisions regarding what information goes out to the public, and this might satisfy the needs of the family members, but some of the details that have come out very late in this case (photos, the child's likes and dislikes) might have helped the search and the investigation if they had been released at the getgo. Again, forgive this, but it almost seems as though there has been a plan involving more than one family member . . . perhaps terribly gone wrong . . . to kidnap the poor child, draw media attention, discover him again, and sell the story.
But there you go—speculation due to public ignorance. This said, I wonder if the news outlets have been following this case on an investigative basis, an adequate budget notwithstanding, following up on theories that are even a bit wild, such as what I posed above.
In a society where information is immediate, albeit not totally accurate, and communication/input is also immediate, impatience at such an investigation is not unusual; add the unanswered fate of a sweet child and you have people wanting more details on the progress of the case. And not hearing media outlets quoting each other, recirculating old details.
Mostly, the public is impatient to have this case solved.
