INDIANAPOLIS -- She’s frustrated, hurt and now for the first time, talking publicly about what she says is clear injustice.

Marion Zerfoss, now a senior at Indiana University, claims she was violated by a man who will not face any criminal charges.

She has tried to stay out of the limelight for the past year - sharing her story only with close friends and family, the university and her legal team - but after learning her alleged attacker will not face charges, she wants her voice to be heard.

“It was my roommate’s 21st birthday and everyone was pre-gaming to go to a bar…” said Zerfoss, “…I became extremely intoxicated, was falling over, and couldn’t speak well …He stated he had a test in the morning, wasn’t drinking, and he had no problem watching me.”

The Monroe County Prosecutor’s Office has pursued her case for nearly a year. But now, just months after a new sex crimes deputy prosecutor has stepped in, they have chosen to stop pursuing charges against the fellow student who Zerfoss says raped her, Aaron Farrer.

RTV6 has confirmed that the prosecutor’s office says there isn’t enough evidence to pursue the case.

Indiana University held a hearing on the allegations and Farrer was eventually expelled.

Zerfoss said she has texts from Farrer apologizing to her that were sent the day after the alleged attack.

Zerfoss says her case may be over – because she can’t imagine trying to take on a civil suit - but on behalf of other students and other possible victims, she wants it to be known that what happened to her isn’t right.

“I think too often the burden of shame is placed on the victim and I’m sick of that,” said Zerfoss. “I think he needs to hold some shame, and be held accountable for this and I don’t want anyone else’s case to be mistreated like my case was.”

Aaron Farrer has maintained his innocence, saying in a statement that he has lost everything due to what he calls “false allegations.”

He said he filed a complaint after he was arrested against Zerfoss in connection with that night to prove that she should have been charged with the same offense as him.
