A University of Colorado student is facing multiple charges of sexual assault after police say he raped a freshman in her dorm room following a fraternity party in November.

Shaan Evamn Sharma, 19, was arrested early Wednesday on suspicion of sexual assault — overcoming victim’s will, sexual assault on a physically helpless victim, and sexual assault — incapable of appraisal.

Those all are Class 3 or Class 4 felonies and are subject to Colorado’s indeterminate sentencing law for sex offenses.

According to an arrest affidavit, a CU freshman said she was at a fraternity tailgate party in the 900 block of 14th Street on Nov. 11. The woman became intoxicated, with witnesses saying she was vomiting and stumbling.

Two fraternity brothers, including Sharma, saw the woman and believed she was too intoxicated to be at the party, and summoned an Uber driver to take her back to her dorm room.

The two fraternity members escorted the woman back to her room, according to the affidavit, and Sharma stayed while the other member decided to return to the party.

According to the affidavit, the woman told police that she was in and out of consciousness, but remembers Sharma sexually assaulting her.

Friends arrived at the room and found the woman naked from the waist down with Sharma in the room. Sharma told them the woman had taken off her clothes on her own, then he left the dorm, according to the affidavit.

In talking with police, Sharma said the woman had hit on him, but that he never had sex with her.

The woman went for a sexual assault examination that found injuries, and the results of a DNA test performed during the exam and returned in March showed traces of Sharma’s DNA on the woman’s body, according to police.

The woman told detectives that the encounter was not consensual. She also denied hitting on Sharma, as she said she is gay.

Sharma is being held without bond pending a first appearance at the Boulder County Jail on Wednesday.

He has no previous criminal history in Colorado, according to court records.
