Accept that what you are declaring as ruled out, really is not. The Sheriff has walked that statement back somewhat in other interviews, including at at the 31:16 mark of a podcast in which he is interviewed one-on-one (google DrydenWire and you'll find the one-hour interview).
Question: "Is Jayme ruled out as a suspect?"
Sheriff: "I think Jame is 13 years old, nothing is off the table. I believe she is endangered and missing. ... There is nothing to point to that (that she was involved) that she texted her friend and said 'Come and rescue me.' But I'm not saying ... because we don't know the answers ... I'm not taking that off the table ..."
I don't know what to make of that.
IMO she is not involved. I can't imagine it. But it is certainly fair to consider and debate. We do not know what the police and family knows. Personally, JMO, I have an uncomfortable feeling about this case when trying to figure out what the police are thinking, based on shaded responses like this interview above, to an uncle's interview in which he said he had a "gut feeling" about what happened and who was involved, to bigger things like not allowing the family to hear the 911 tape. Words and tactics matter in these things. JMO
