Lauren Spierer's family has filed a lawsuit against three former college students who were the last people seen with the missing Indiana University student.
Spierer, a sophomore at Indiana from Greenburgh, N.Y., disappeared two years ago in Bloomington, Ind., after a night of partying with friends and acquaintances.
Robert and Charlene Spierer claim in a lawsuit that their daughter's last known interaction with Corey Rossman, Mike Beth and Jay Rosenbaum is to blame.
Her interaction with the three former students ultimately resulted in the 20-year-old's "disappearance, death or injury," according to attorney Jason Barclay.
The complaint says the men's negligence led to the disappearance of Lauren Spierer, which remains unsolved, according to state and local police.
