New video footage uncovers 12 separate vehicles speeding by in Nancy's neighborhood between 12 a.m. and 6 a.m. the very night Nancy is abducted.

One of those vehicles speeds by just eight minutes after Nancy Guthrie's pacemaker stops connecting to Bluetooth. What is the significance? Is it connected to Guthrie's disappearance?
