It sounds like the police have a suspect. I was suspicious of the step-mother’s story from the beginning of this ordeal.
It's about time. When the 4 parents finally surfaced, the Oregonian had a front page photo of the Mom and step-Mom. The Mom is visibly visibly upset, while the step-Mom has her eyes directed at the ground with no visible signs of duress. I know this is all based on one photo, but my wife and I picked up on it instantly. It's almost eerie. I'm sure law enforcement noticed the same thing.
Plus, the step-mom took two time-stamped photos of Kyron at a Science Fair prior to school, then within a half-hour, he disappears. I'd like to know where she was at as well. To top it all of, the step-mom kept posting on Facebook, even things like "Heading to the gym!" just days after Kyron disappeared.
