Washington (CNN) -- Two more charges have been dropped against the man accused of killing Washington intern Chandra Levy, sources familiar with the case said Monday.
Ingmar Guandique will not be tried on attempted kidnapping and attempted robbery charges because the statute of limitations has expired, the sources told CNN.
Prosecutors previously asked the judge to drop felony sexual assault and associated murder charges due to the lack of physical evidence in the case.
Guandique still faces felony first-degree murder charges in Levy's 2001 death.
Prosecutors believe Guandique, a reputed member of the Salvadoran gang Mara Salvatrucha, attacked Levy while she was jogging in Washington's Rock Creek Park and then killed her when she began to scream.
Her body was found more than a year later by a man walking his dog in a wooded area of the park.
Guandique denies that he attacked Levy. There has been no physical evidence linking him to the assault, leaving prosecutors to base their case largely on Guandique's alleged jailhouse admission that he killed Levy, then an intern for the federal Bureau of Prisons.
