The Usual Suspects

Sam and Dean investigate the murders of a lawyer and his wife who, right before they died, claimed to have seen a ghost. Before the brothers are able to find the ghost, however, local detectives Ballard and Sheridan uncover the Winchesters' records and arrest them for a double homicide. When the ghost begins to visit Ballard, she wonders if Sam and Dean really are telling the truth--and if she might be the next to die.
