Lawyers for the man convicted of killing D.C. intern Chandra Levy plan to file a motion for a new trial, the Associated Press reported.

Ingmar Guandique, an illegal immigrant from El Salvador, was convicted of murdering Levy in 2010 and is serving a 60-year prison sentence. But in the past few months, a judge held secret meetings that could indicate there was an issue with the prosecution. In a partially unsealed document released Tuesday, Guandique's lawyers said his prosecution was "predicated on a lie."

Levy, a 24-year-old intern at the Federal Bureau of Prisons, disappeared in 2001, and her remains were found in Rock Creek Park a year later. The case made headlines because of Levy's affair with then-Rep. Gary Condit.
