A D.C. judge has granted a retrial in the murder of Chandra Levy.

The Post reports that D.C. Superior Court Judge Gerald Fisher agreed today to bring the case back before a new judge and jury, nearly 15 years after Levy’s remains were found.

In 2010, 34-year-old Ingmar Guandique was tried and convicted of killing Levy, who was a Federal Bureau of Prisons when she disappeared in 2001 while jogging in Rock Creek Park. Guandique was sentenced to 60 years in prison after a cellmate testified that he confessed to him that he killed Levy.

But Guandique’s lawyers argue that his conviction “was based on a lie,” according to the Post. His attorneys say that the government never disclosed to them that their key witness—who is a convicted drug dealer and gang member—had cooperated with prosecutors in other cases, and his testimony may have been spun so that he could get his sentence reduced.

Levy disappeared on May 1, 2001, and her remains were found in Rock Creek Park a year later. Her disappearances became a national story when police initially suspected former California congressman Gary Condit, who was having an affair with Levy at the time.

Years after Condit was cleared, Guandique—who was serving a ten-year prison sentence for assaulting two other women at knife point in Rock Creek Park—was tried and convicted for killing Levy. However, “no eyewitnesses, forensic evidence, nor medical cause of death linked Guandique to Levy’s death.”
