A judge has refused to push back the trial for the man accused of sexually assaulting and killing a Washington intern.

At a hearing Friday, prosecutors told D.C. Superior Court Judge Geoffrey Alprin that they have provided more than 5,000 pages of evidence to attorneys for Ingmar Guandique (gwan-DEE'-kay.)

Chandra Levy had just completed a U.S. Bureau of Prisons internship when she disappeared in 2001 after leaving her apartment in jogging clothes. Her remains were found a year later in a Washington park.

Defense attorneys say they need to interview at least 10 other possible suspects. They asked to push back the January trial date, but Alprin refused.

Guandique's lawyers have said the case against him is flawed. He was charged in the killing earlier this year.
