Police are using new surveillance video to help in the search for a Scarsdale college student missing in Indiana. Lauren Spierer, a student at the University of Indiana, has been missing for six days after she left a bar near the Bloomington, Ind. campus. She was last seen at around 4:30 a.m. Saturday morning, and police say they located her shoes at a bar and her keys in the street. Police say the security footage is from a camera outside Spierer's on-campus apartment. They confiscated computers, hard drives and discs yesterday from her apartment building's security office, and have reportedly come across what they are calling "items of significance". Police, volunteers and the girl's parents have kept their search within Bloomington city limits, but today decided to expand into neighboring areas. The National Center for Missing and Exploited Children is also assisting in the search efforts.Vigil held for college student from Scarsdale who went missingFamily, friends search for missing Scarsdale woman
