Green River County Detention Center is a prison Sam and Dean are briefly detained in.
The brothers soon discover that the prison is haunted by a ghost, initially suspected to be one of the inmates, but later proven to be a nurse, who was killed during a prison riot. With the help of Deacon Kaylor and Mara Daniels, the brothers manage to salt and burn the nurse's remains and end her rain of terror.

- During the escape, Deacon removes a panel from the wall of the shower room leading to the outside. Given the unlikelihood of such a panel existing naturally in a place where the inmates could find it and escape and the presence of the Impala parked outside, it was likely precut by the Winchesters or Deacon for the escape plan.
