Voted no clue.
There is no evidence that TH did anything other than drop Kyron off at school. There is at least one witness who places Kyron at school after TH left. All the rest is rumor, innuendo, supposition, dirty laundry, and voodoo science.
If there was something that was a concrete bit of evidence, there would've been an arrest. There isn't, and LE knows this. The pressure they've put TH under is enormous, and yet she hasn't 'cracked', took a long time to 'lawyer up', took several polies (*notorious voodoo science), and has had her life, weight, parenting style, social graces, ability to deal/not deal with stress, medical records, choice of careers, personal history, way of keeping house all torn to bits looking for something - anything - that would give one a bit of solid, factual evidence...
I didn't vote no, because I'm a wuss.
