Washington (CNN) -- After more than three days of deliberations, jurors on Monday convicted Ingmar Guandique of two counts of first-degree murder in the 2001 death of Washington intern Chandra Levy. As the verdict was read, Levy's mother, Susan, stared intently at Guandique. Several jurors wiped their eyes afterward. Levy, a 24-year-old California native, was in Washington working as an intern for the Bureau of Prisons when she was last seen on May 1, 2001. Her skull was found over a year later, on May 22, 2002, in Washington's Rock Creek Park. But police didn't arrest Guandique until February 2009. He was then serving a 10-year sentence for attacking two other women in the park and had reportedly spoken about killing Levy.
