|Location||Highway 41 in Nevada|
Fifteen years ago Molly McNamara and her husband David were driving along Highway 41 in Nevada when they hit and killed Jonah Greely. Molly died but is unaware that she is dead, remaining behind even after she was cremated (apparently out of concern for her husband due to her lack of knowledge of his fate). Each year on the anniversary of his death, Jonah finds another car driver to kill, simultaneously torturing Molly for her own role in his death.
When Sam and Dean meet Molly, who had learned about the deaths that took place on that highway at specific times of year, they don't tell her that she is dead, hoping she will help them find Jonah's remains. They find Greely's cabin, but Jonah grabs Molly and starts to torture her. Greely is dispatched when Sam salts and burns his corpse.
Finally the boys reveal to Molly that her husband is alive and she is dead. Satisfied that David is safe, Molly accepts her fate and her spirit disappears with the sunrise.
