Jody Mills

She is sheriff of Sioux Falls, South Dakota. She also knows Bobby Singer.

Background
She first appears in Dead Men Don't Wear Plaid when she walks into the diner noticing two men talking to "Digger". She asks Sam and Dean who they are, and they reply FBI. When they give her their "supervisor's" number, she finds out its fact, Bobby Singer, by recognizing his voice. She later arrests Sam and Dean when they go after a man who had come back from the dead. This shows that she knew about the dead rising. In fact, her own son, had come back, which is the reason she is not taking action on this matter. Bobby later comes by and talks to her as well as getting Sam and Dean out.

Then her son starts to get sick and she is very worried. But when she walks back into the room, she finds her husband dead, and her son eating him. As she backs away, Sam comes in and saves her. He gets her out, and she tries to go back and save her husband, but Sam tells her that her husband is already dead. Sam goes in and shoots her son. She knows its right, but is still hurt by his death. So she teams up with Sam and gets the town ready for the Zombie attack. She and Sam later arrive to save Bobby and Dean. After the attack, she and Dean sweep the area for any remaining zombies.

She later returns in Weekend At Bobby's, when she and an FBI agents arrive at Bobby's door.
