An elderly couple who vanished for more than a week were lost thanks to a faulty satnav, which cost one of them their lives.
Ronnie and Beverly Barker had been on their way home from a road trip across the western US when they suddenly stopped communicating with their family back home.
Terrified, they raised the alarm and a week later were found lost on a mountain after going in search of help in their car when their motorhome became stuck in mud.
