The Boulder County District Attorney's Office has taken a support roll in the investigation of a co-ed's allegation that she was raped at a party attended by University of Colorado football players and recruits.

The district attorney adviser and a city detective are helping campus police, who are leading the investigations, said Jana Petersen, city spokeswoman.

The adviser, who was not identified, can help police determine whether charges are warranted for the student's allegations that she was assaulted by several people at an off-campus party Dec. 7. Campus police are leading the investigation because the student approached them first.

CU athletic spokesman Dave Plati refused to answer questions Monday and referred calls to the police.

"The investigation is continuing," said Lt. Tim McGraw, campus police. "There's a lot of avenues we need to go down and we're doing that."

He declined additional comment. Petersen said city police also had nothing new to report.

University spokeswoman Bobbi Barrow said no timetable was given for how long the investigation would continue.

"This is a complex investigation because it involves a lot of people," she said. "It normally takes a considerable amount of time to complete."

Football coach Gary Barnett has said the allegations have not distracted the team, ranked fourth in the nation in The Associated Press poll, from preparing for the Fiesta Bowl.

On campus, the case has been on the minds of students who are in the midst of final exams.

Freshman Katrina Moseley and her friends reserved tickets for the bowl game the first day they became available. Last weekend, she learned some of the players who helped get the Buffaloes to the big game have been accused of attending the party.

"With all the good publicity about CU, it was shocking to see other bad things happening on campus," she said Monday. "It takes down the spirit of the whole campus. It brings the whole mood down."

Junior Matt Kanda, fresh out of a final exam, said he hadn't had a chance to ask his high school classmate and Buffs wide receiver , Jason Burianek, what he knew about the allegations.

"I'm trying to stay unbiased," Kanda said. "No one has any idea what went on.

"I hope it isn't true, for the sake of the victim and the team, too."
