Acting at a preliminary hearing, District Judge JoAnn Spinks Coleman also denied a motion to set bond for Lucas Goodrum, 21, and Stephen Soules, 20, both charged with murder in the death of 18-year-old Katie Autry.
The grand jury would likely take up the case in a week.
Autry, a freshman, was found beaten, stabbed and burned in her dorm room May 4, and she died three days later.
According to police affidavits, Soules told police that he watched Goodrum rape, beat, burn and try to suffocate Autry with a pillow. Autry's body was also doused with hairspray, court records show.
David Broderick, the attorney for Goodrum, argued that there has been no physical evidence linking his client to Autry's room on the night of the fire.
``Nobody other than Mr. Soules has implicated my client,'' Broderick said.
Prosecutors are still waiting DNA and blood test results from Goodrum and Soules, who were high school classmates.
Police have said the pair attended a fraternity party on the school's campus hours before the fire. Friends say Autry attended the same party. Investigators have not said whether she knew the two, however.
