Almost exactly a year after college student Lauren Spierer disappeared after a night out with friends in Bloomington, Ind., police say her case is still active. Her mother, Charlene Spierer, said Friday that she always has hope her daughter is alive but “after a year, I don’t think it’s likely.”
Lauren’s father, Robert Spierer, told TODAY’s Savannah Guthrie: “You have to be realistic ... you always have that small element of hope, but of course, as time goes by, you become more and more realistic about the possibility of her being alive.“
On Thursday, the Bloomington police department said it has investigated more than 2,500 tips and that Lauren’s disappearance is still under investigation. They said two to three credible tips come in weekly, and they require extensive follow-up.Story: Mom of missing coed: ‘It’s like having your heart ripped out’
Lauren, 20 years old at the time she went missing, was attending classes at Indiana University. She was only days away from returning home to New York for an internship during the summer break. It is understood that Lauren left Kilroy’s, a sports bar, the night of June 3, 2011, with friend Corey Rossman around 2:30 a.m.
Though she went to her apartment building, she did not go home, allegedly going to Rossman’s apartment. She was reportedly last seen leaving his apartment.
Rossman's attorney has said in the past that his client has no memory of his last moments with Lauren because he was punched in an altercation at the apartment complex, though he doesn't remember being punched, or the 15 minutes before he was allegedly hit.Video: Missing coed’s parents plead for her return (on this page)
Robert Spierer told Guthrie: “What we do know is the people who were with her that night really did nothing to help her, and that’s part of the tragedy around this.”
Charlene Spierer agreed. “We’re aware of the fact that Lauren was not in great shape, and the idea that Lauren was on the floor of her apartment building and steps away from her apartment and she could’ve been taken home and was not is unconscionable.”
Robert said that when Lauren first disappeared, her friends were open and forthcoming with the family and police, but soon people “lawyered up” and the “lines of communication became nonexistent or severely limited, and to this day many of those people — most of those people — have not taken police polygraphs, which is what we’ve asked for from the beginning.”Video: Lauren Spierer’s sister: We’re doing the best we can (on this page)
Sister Rebecca Spierer, 25, accompanied her parents on TODAY, one of the first times she’s spoken out about the case. She said, “We could’ve never imagined still a year later and not having the answers that we so desperately want. But every day we’re just trying to stay together, we’re leaning on each other and we’re doing the best we can.”
Though the family has admitted Lauren’s case looks bleak, they have still not given up hope. He mother said, “We’re committed and we’re driven and we just go through every day thinking about what we can do to make a difference, and try to get closer to finding Lauren.”
