Christopher protected his wife and himself. As a father of three little boys under 5, he would never do anything to prevent himself from being with them, unless it was life or death. They didn't run to Moslow to hide, that's where the US Embassy is, as a soldier on leave, didn't they need advice on how to turn themselves in to the Russian police. Just my thoughts. Our prayers are for all the people involved, Christopher, Svetlana, their babies, judges, lawyers, and the family's on both sides. We, his extended family, are all praying for his return home.
