In 1959 Perry Smith and Dick Hickock invaded a Kansas farmhouse in a senseless robbery that netted under $50. After tying up the four family members in separate rooms, they blasted them with a shotgun to eliminate all witnesses. Two months later the men were captured and placed in separate interrogation rooms. The police had enough evidence to convict them for parole violation and passing bad checks, but the evidence for murder was thin. The prosecutor needed a confession.
