INDIANAPOLIS (AP): A federal judge is set to hear arguments on a motion to dismiss the lawsuit filed by a missing Indiana University student's parents against three men who were with her the night of her disappearance.
 
       Lawyers for the parents of Lauren Spierer and the three men are to appear Monday afternoon before Judge Tanya Walton Pratt at the federal courthouse in Indianapolis.
 
       The lawsuit claims the fellow IU students gave Spierer alcohol, then failed to make sure the 20-year-old Greenburgh, N.Y., native made it back to her Bloomington apartment safely after a night of partying in June 2011.
 
       Lawyers for Corey Rossman, Michael Beth and Jason Rosenbaum maintain the Spierers have no evidence their daughter is dead and that they weren't responsible for the safety of an adult.
