A federal judge has thrown out the lawsuit filed by the parents of an Indiana University student last seen more than three years ago against two men who were with her the night she vanished. Judge Tanya Walton Pratt says in her ruling issued Tuesday that Lauren Spierer's parents didn't present evidence showing the men had anything to do with her disappearance. The 20-year-old Greenburgh, New York, native disappeared in June 2011 after a night of partying with friends in Bloomington. The lawsuit claimed fellow students Jason Rosenbaum and Corey Rossman gave her alcohol and didn't make sure she returned safely to her apartment, leading to her presumed death. Spierer family attorney Jason Barclay says ruling will be appealed as Spierer's parents try to find out what happened to her.
