as to which of the two shot the women, Bonnie and Nancy Clutter. Alvin Dewey, chief investigator of the Clutter family murders, testified at the trial that Hickock insisted in his confession that Smith performed all four killings; Smith, however, first confessed that Hickock killed the women, but refused to sign his confession, and later claimed to have shot them himself. Although Smith's revised confession coincided with Hickock's initial statement, both Smith and Hickock refused to testify in court, leading to a lack of an official record detailing who killed the women. While Smith had only a grade-school education, he maintained a strong interest in art, literature and music. His rough past regarding his family and abusive childhood led him to be somewhat distant from people. He read extensively, and during his time on death row, wrote poems and painted pictures for other inmates from photos of their family members. Relationship with Truman Capote During research for his novel In Cold Blood, Truman Capote extensively interviewed Smith and eventually befriended him. Execution Smith and Hickock were executed by hanging on April 14, 1965. Smith was hanged second, dying at 1:19 a.m. Exhumation Nearly 50 years after the executions, the bodies of the killers were exhumed from Mount Muncie Cemetery in Lansing, as authorities hoped to solve a 53-year-old cold case using DNA. Smith and Hickock had originally been questioned about the December 19, 1959, shooting murder in Osprey, Florida of Cliff and Christine Walker and their two young children. Evidence indicated they had spent time just a few miles from the Walker crime scene after the Clutter murders. A polygraph administered at the time of their arrest cleared them of the murders, but by modern polygraph standards, their test results are no longer considered valid. On December 19, 2012, officials in Kansas exhumed the bodies of Smith and Hickock and retrieved bone fragments to compare their DNA to semen found in the pants of Christine Walker. In August 2013, the Sarasota County Sheriff's office announced they were unable to find a match between the DNA of Smith or Hickock and the samples in the Walker family murder. Only partial DNA could be retrieved, possibly due to degradation 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). Investigators have stated that Smith and
