Cummins, 50, fled with Elizabeth, his student, from their small town of Culleoka, Tennessee, on March 13. Authorities released surveillance video from March 15 that showed the pair at a Walmart in Oklahoma City. But then the trail has gone cold.

The two disappeared a few weeks after a student reported seeing Cummins and Elizabeth kissing in a classroom.
