Match up the photos of the holiday till that day, what they are wearing, the time of day the photo was taken, any time stamp available, the gaping and times of these texts.
I guess the story won't match and this calls into account the facts about sleeping tablet medications perceived to have been administered by both the parents without knowing that Madie had been double dosed. My timeline, shunts her death to the previous morning, they covered it up during the day and staged the "oh my kid has been taken" for that night to throw off any blame comming their way.
Sad for Kate and Gerry, but I hope the cops can get to the right conclusion.
