The Levy homicide remained listed as a "cold case" until 2006, when Cathy L. Lanier succeeded Ramsey as D.C. police chief. Lanier replaced the lead detective on the case with three veteran investigators who had more homicide experience. In 2007, the editors of "The Washington Post" assigned a new team of reporters to take a year to re-examine the Levy case. The resulting series of articles, published during the summer of 2008, focused on the past failure of the police to fully investigate Guandique's connection to the attacks in Rock Creek Park. In September 2008, investigators searched Guandique's federal prison cell in California and found a photo of Levy that he had saved from a magazine. Police interviewed acquaintances of Guandique and witnesses of the other Rock Creek Park incidents.
