Ten days after an Indiana University student vanished, Bloomington police said Monday they plan to release enhanced security camera video in the hope the public can help identify the vehicle or vehicles that drove through the area around the time the woman disappeared. Lauren Spierer, 20, was last seen walking home alone from a friend's apartment about 4:30 a.m. June 3. Police Capt. Joe Qualters said one—and possibly two—vehicles are visible in video sequences police obtained from cameras near where the Greenburgh, N.Y., native vanished. Police want to talk to the drivers, and if it turns out the footage actually shows one vehicle circling through the area, that would be particularly interesting, he said.
