Smith later recounted, "I didn't want to harm the man. I thought he was a very nice gentleman. Soft spoken. I thought so right up to the moment I cut his throat." Kenyon, Nancy, and lastly Bonnie Clutter were also murdered, each by a single shotgun blast to the head. During their commission of the crimes, Smith prevented Hickock from raping Nancy. Hickock and Smith left the crime scene with a small portable radio belonging to Kenyon Clutter, a pair of binoculars belonging to Herbert Clutter and less than $50 in cash believed to have been the "change" from a $60 check Herbert Clutter had recently cashed. Herbert Clutter was well-known locally as a businessman who preferred paying by check and never carried or kept significant amounts of cash. His billfold and scattered non-cash items were found in his first-floor bedroom. Smith later claimed in his oral confession that Hickock murdered the two women. When asked to sign his confession, however, Smith refused. According to Capote's "In Cold Blood", Smith wanted to accept responsibility for all four killings because, he said, he was "sorry for Dick's mother". Smith added, "She's a real sweet person." Hickock always maintained that Smith had murdered all four victims. The four murder victims are buried at Valley View Cemetery in Garden City, Kansas. Before the killers were captured, author Truman Capote learned of the Clutter family murders and decided to travel to Kansas and write about the crime. He was accompanied by his childhood friend and fellow author Harper Lee. Together, they interviewed local residents and investigators assigned to the case and took thousands of pages of notes. The killers, Hickock and Smith, were arrested six weeks after the murders and were eventually executed by the state of Kansas in 1965. Capote ultimately spent six years working on his book. When finally published in 1966, "In Cold Blood" was an instant success. Today, it is the second-best-selling true crime book in publishing history, behind Vincent Bugliosi's 1974 book "Helter Skelter", about the Charles Manson murders.
