Jonah Greely

==Background]] Fifteen years ago Jonah Greely was hit and killed by Molly McNamara and her husband David on Highway 41 in Nevada. His wife was so distraught that she killed herself. Each year on the anniversary of his death, Jonah finds another car driver to kill.

As Sam and Dean search for Greely's corpse, Jonah's ghost grabs Molly and starts to torture her. Greely is dispatched when Sam works out that his wife planted a tree as a grave marker, and salts and burns his corpse.
