There is no forensic evidence that ties Ingmar Guandique to the May 2001 slaying of federal intern Chandra Levy. Whether that means Guandique is a calculating killer who chose to attack Levy in a secluded area of Rock Creek Park, where her body would not be found for a year, or is innocent in her death is what a D.C. Superior Court jury will decide.

Closing arguments took place Tuesday in Guandique’s monthlong trial on first-degree felony murder charges, and the jury begins deliberating Wednesday morning.
