The murder continued to attract public attention and media coverage long after the trial was over. In 2004, the ABC News program 20/20 aired a controversial report quoting claims by McKinney, Henderson, and Kristen Price, the prosecutor and a lead investigator that the murder had not been motivated by Shepard's sexuality but rather was merely a drug-related robbery that had turned violent.[21] Critics charged that the report, which featured interviews with Shepard's murderers, was sensational, misleading, and downplayed or ignored evidence of homophobia as a motivation for the crime.[55][56][57][58]
Dave O'Malley, the Laramie police commander over the investigations division at the time of Shepard's murder,[59] stated that the murderers' claims were not credible, but the prosecutor in the case stated that there was ample evidence that drugs were at least a factor in the murder.[60] Other coverage focused on how these more recent statements contradicted those made at and near the trial.[61]
In September 2013, The Book of Matt: Hidden Truths About the Murder of Matthew Shepard by Stephen Jimenez, the producer of the 20/20 segment, was published. The book revived and expanded upon claims by the author that Shepard's murder was at least partly drug-related and that, contrary to the generally accepted version of events, his sexual orientation was not a major motive for the crime. Additionally the author claimed that Shepard and at least one of his killers (McKinney) had been occasional sexual partners
