Several hundred people participated in a Lauren Spierer awareness ride in Indiana on Saturday.
The 45 mile motorcycle ride was the latest in a series of events organized by her family to keep public attention on the case.
"We are determined to find Lauren, so we're here still in Bloomington. We're not giving up hope. We're not giving up the effort," Lauren's father Robert Spierer said.
Lauren Spierer, a 20-year-old Indiana University student, disappeared after a night out with friends in Bloomington on June 3rd.
