The parents of a student missing since 2011 have resorted to suing the men that last saw their daughter.

20-year-old Lauren Spierer vanished from the Indiana University campus, where she was a sophomore.

According to the Daily Mail, she disappeared after a night out with a group of friends that included Corey Rossman, Mike Beth and Jay Rosenbaum.

"Rob and Charlene Spierer authorized the filing of this lawsuit with great reluctance and only after we counseled them that they would lose certain legal rights if not exercised by the two-year anniversary of Lauren’s disappearance," attorney Jason Barclay says.

The suit alleges that the men's actions prompted Spierer's disappearance. She was last seen on June 3, when she went to Rosenbaum's apartment.

"We intend to use the rights afforded by the civil justice system to obtain answers to questions that have gone unanswered for too long. We fully expect that those with relevant information will cooperate with this process," Barclay notes.

According to Fox News, many events occurred that night. She left her apartment in Smallwood with friend David Rohn, met up with Rosenbaum at his apartment, presumably consumed alcohol, headed to a bar than returned to Smallwood.

Rossman and student Zachary Oakes engaged in a brawl on the floor where Spierer lived at Smallwood, and they left for his apartment once more.

Two more people were there at the time. Witnesses have said that she was being carried there by Rosenbaum. She then allegedly left to get back home on her own one hour later.

"How they both got back to Corey’s apartment had to be a result of the initiative of Corey [Rossman] and certainly not Lauren, so I don’t know how bad a shape he could have been in because he was able to get both he and Lauren back to his apartment after he got hit at Smallwood," Robert Spierer argues.

"For her to recover in such a short period of time, call it an hour or more, doesn’t make sense to me," Spierer adds.
