Tempe determines the bones are from different corpses, suggesting a serial killer's handiwork. A suspect is quickly taken into custody, but Tempe senses the case is far from closed. And as Booth's Mafia case heats up with violent twists and bloody discoveries, including ties to one of Chicago's most gruesome and notorious killers, Tempe must unravel the story of the bones, where the truth lies buried -- in order to stay alive.
