WARNING: CRIME SCENE PHOTOS ARE GRAPHICTwo families, mysteriously murdered under similar circumstances, just a month apart. One was memorialized in Truman Capote’s classic novel, In Cold Blood. The other was all but forgotten. Dick Hickock and Perry Smith confessed to the first: the November 15, 1959 murder of a family of four in Holcomb, Kansas. Despite remarkable coincidences between the two crimes, they denied committing the second: the December 19 murder of a family of four in Osprey, Florida. Over half a century later, a determined Florida detective undertakes exceptional efforts to try to bring closure to the long-cold case.
