During his time in prison, Cox introduced himself to arms trader Efraim Diveroli after reading a Rolling Stone article on him, and encouraged him to write a memoir. Diveroli agreed to let Cox write the memoir, as he had "boxes of evidence" under his bed while fighting his own trial. When Diveroli left the complex, he took the manuscript with him and Cox claims to not have been compensated for it since; as of 2019 the two are in a mediated settlement process. After writing this memoir, other inmates approached Cox to write their stories down, resulting in a number of true crime manuscripts being written by Cox in prison.
