Following a series of investigative reports by The Washington Post in 2008, the MPD followed up and finally obtained a warrant, on March 3, 2009, to arrest Ingmar Guandique, identified and dismissed by the MPD eight years earlier. He had been convicted of assaulting two other women in Rock Creek Park around the time of Levy's disappearance and was still in prison on those convictions when the arrest warrant on Levy's death was issued. Prosecutors alleged that Guandique had attacked and tied up Levy in a remote area of the park and left her to die of dehydration or exposure. In November 2010, Guandique was convicted of murdering Levy; he was sentenced in February 2011 to 60 years in prison. In June 2015, Guandique was granted a new trial. On July 28, 2016, prosecutors announced that they would not proceed with the case against Guandique and would instead seek to have him deported. In March 2017, Guandique lost his bid to remain in the United States and was deported to his native El Salvador on May 5, 2017. Levy's murder remains unsolved.
