Lauren Spierer was seen at Kilroy's Sports Bar on the night of her disappearance.
The Spierer's say they hope the new flyers will encourage someone to come forward with information about their daughter.
Charlene Spierer reiterated her pleas for those who have information to come forward.
Saturday is “Find Lauren Day” and the Spierer’s hope volunteers will help canvass the area in the search for their daughter.
Volunteers are urged to gather at 8 a.m. at McNutt Quad on the IU Campus.
IU officials confirm that a donation of $50,000 will be given to the Spierer family.
