The grave of Richard Hickock, a convicted killer who along with Perry Smith was chronicled in Truman Capote's book "In Cold Blood", is seen in the Mount Muncie Cemetery in Lansing, Kansas in this December 4, 2012, file photo. The bodies of two men executed for the 1959 murders of a west Kansas family in a case made famous by the book "In Cold Blood" were exhumed December 18, 2012, as part of an investigation into a quadruple homicide in Florida that same year.
