The complaint filed by Spierer's parents, Robert and Charlene Spierer, on May 31, claims negligence on the part of Corey Rossman, Jay Rosenbaum and Michael Beth, who were partying with their daughter on the night of June 2, 2011, and into the next morning in Bloomington, Ind. Spierer has not been seen since.
The suit alleges that Rossman and Rosenbaum supplied Spierer with alcohol after she was already "visibly intoxicated," and then failed to see that Spierer returned safely to her apartment, which led to her injury and likely death. The suit also claims that Beth saw "Spierer was extremely intoxicated and witnessed Rossman encourage Spierer to join him" at a sports bar to consume more alcohol.
Spierer, originally from Greenburgh, N.Y., was 20 years old at the time of her disappearance.
The suit was filed in Monroe Circuit Court days before the expiration of the statute of limitations for a civil filing, according to WTHR. Federal courts have jurisdiction because the parties to the suit are all from different states, according to WISH-TV.
None of the men in the suit have been named as suspects in Spierer's disappearance, the Associated Press reports. Attorneys for the three defendants did not return request for comment from the AP.
The family hopes the lawsuit will prompt the men to be more forthcoming about what happened that night, their attorney Jason Barclay told Fox News, as Spierer's parents expressed doubt that the men have told the whole truth.
Spierer's parents told Katie Couric in December that only one of the men had agreed to meet with them.
"I truly don't think it was a random abduction," Charlene Spierer told Couric at the time. "I think that somebody that Lauren knew was responsible for the events of that evening."
In the two years since Spierer's disappearance, despite more than 3,000 tips, no arrests have been made and her body has not been found.
