JMO the reason all three (grandparents and Nathan) are taken from home is to hide evidence to link the perp to the crime, it seems planned, perhaps money (from an 'Estate' sale) was the motivation. Perhaps the child was the intended goal. One person is in medical distress, likely the Grandfather who would have fought to protect his wife and grandchild. It is my hope that the Grandmother is protecting the grandchild, she would be using all her coping skills to survive. Be STRONG. The individual who committed this crime has no conscious, they might be watching all of this unfold, enjoying their notoriety. LE must have hits on the green truck, they are closing in and I am hopeful they find Nathan soon. My thoughts and prayers are with the family. Many abducted children have been found and we must continue to hold out hope.
