"I was just pleased that IU and these students got together to do something constructive in the wake of Lauren's disappearance," said Robert Spierer.
The students presented ideas like developing smartphone applications to help keep them safe on and off campus.
"I really hope that our message of bringing hope and awareness and safety to the IU campus, to Bloomington and to the whole nation was expressed and I hope her parents understand our compassion and our message," said Freshman Kelly Bershader.
"The ideas presented inside the classroom could actually become real life safety tools with the help of WTTS radio here in Bloomington."
"I hope that they will be able to do some of these things. I think some of the ideas are feasible, but also not terribly expensive and might make a difference," said Professor Sue Vargo.
And the Spierers agree.
"The students did an amazing job and that even if we could come away with one idea, it would be well worth it," said Charlene Spierer.
Lauren's case is still an active investigation with the Bloomington Police Department. The Spierers said they are also still working with a private investigator in the case.
