On Saturday morning, 23 months and one day after Spierer's disappearance, her mother Charlene took to social-media site Twitter to repeat her call for someone, anyone, to break the silence and step forward with information.
"You may forget where you were and what you were doing on 6/3/11 but we never will," Charlene Spierer wrote.
IU president Michael A. McRobbie is bringing a message of support for Spierer and her family at the morning and afternoon commencement, a university spokesman said Friday afternoon.
"He's going to say a few words right at the top of commencement ceremony and right before the invocation, just reiterating our support for her and for the family," Mark Land said.
A Bloomington, Ind.-area rabbi who has become close to the Spierer family may give the invocation, Land said. The university is holding its commencement in two sessions due to the large size of its graduating class; some 7,000 undergraduates will receive diplomas Saturday, Land said.
Spierer, a 20-year-old student at Indiana at the time she vanished, was last seen June 3, 2011, leaving Kilroy's Sports Bar in Bloomington after a night out with friends. Since then, the trail has gone cold for police and private detective Richard "Bo" Dietl, hired by the Spierer family.
Spierer's parents, Robert and Charlene Spierer, have said repeatedly they believe that their daughter's friends know what happened the night she disappeared but won't talk to investigators because the facts could get them in legal trouble. The Spierers have said they believe Lauren is no longer alive but still cling to "the dimmest of hopes," as Robert Spierer told Katie Couric on her syndicated TV talk show in December.
The Spierers will not attend Saturday's graduation, according to media reports, but plan to revisit Bloomington in July to continue their quest to find answers.
A call to the Spierers' home in Greenburgh was not returned Friday.
On Sunday, a group of volunteers put up fliers with Lauren Spierer's picture and other information on the Indiana University campus in an event called PUMP 4 Lauren, which stood for "Putting Up More Posters for Lauren."
Since Lauren Spierer's disappearance, her parents have doggedly kept hope alive for answers, keeping a high media profile. After appearing on Couric's show, they granted an extensive interview to People magazine in January.
Along the way, there have been false alarms, in the Spierer family search for answers.
Last May, the case of a missing Louisiana college student was briefly thought to have links to Spierer's case before authorities ruled that out.
Then last July, a skull was found in Indiana's White River near Indianapolis. Forensic testing showed it wasn't Lauren Spierer.
