Hickock and Smith were both buried in nearby Mount Muncie Cemetery in
Lansing, Kansas. Hickock donated his eyes for
corneal transplants, and they were used on two patients in Kansas City later that day. On December 18, 2012, the killers' bodies were exhumed from Mount Muncie Cemetery, as authorities hoped to solve a 53-year-old
cold case using DNA. Smith and Hickock had fled to
Florida after the Clutter murders, and the two had been questioned about the December 19, 1959, shooting murder of
Cliff and Christine Walker and their two young children. A
polygraph administered at the time of their arrest in the Clutter case cleared them of the Walker family murders, but by modern polygraph standards, their test results are not considered valid. After the exhumation, officials in Kansas retrieved bone fragments from Smith and Hickock's corpses to compare their DNA to
semen found in Christine Walker's pants. In August 2013, the
Sarasota County sheriff's office announced they were unable to find a match between the DNA of either Smith or Hickock with the samples in the Walker family murder. Only partial DNA could be retrieved, possibly due to degradations of the DNA samples over the decades or contamination in storage, making the outcome one of uncertainty (neither proving nor disproving the involvement of Smith and Hickock). Consequently, investigators have stated that Smith and Hickock still remain the most viable suspects. In 2017,
The Wall Street Journal uncovered a handwritten manuscript that Hickock wrote while he waited for his execution on
death row. The manuscript, reportedly titled
The High Road to Hell, allegedly suggested a motive for the murders, which remains disputed. Before his execution, Hickock had insisted (and Smith concurred) that Smith committed all of the murders. However, Hickock's manuscript describes how he shined a flashlight on each of the four Clutters' heads while Smith fired; Hickock's only regret, according to the manuscript, was that Smith killed all the victims and Hickock committed no murders. In discussing his alleged motive, Hickock claimed that he had committed the killings in a
murder-for-hire plot in exchange for $5,000 from a man only named Roberts, writing, "I was going to kill a person. Maybe more than one. Could I do it? Maybe I'll back out. But I can't back out, I've taken the money. I've spent some of it. Besides, I thought, I know too much." Throughout 1961, Hickock sent the manuscript to reporter Mack Nations, who had promised to convert it into a book-length manuscript. After completing the project, Nations sent the converted manuscript to the publishing company
Random House, but they returned and advised they had already commissioned Capote to write about the murders. Writer Kevin Helliker of the
Journal speculated that Hickock may have been
pathologically lying or
engaging in fantasy in his manuscript, arguing that had Hickock's story been true, he and Smith likely would have used the information to try to negotiate their way out of their death sentences by pinning the crime on Roberts, and he and Smith would not have struggled to make ends meet after the crime if they had been paid for it. Michael Stone, a
Columbia University psychiatrist who specialized in studying Smith and Hickock, read the manuscript at the request of the
Journal and said on the record, "I don't believe for a minute that they got paid to do it."
