Indiana University student Lauren Spierer was last seen in the early hours of June 3 as she left a bar in downtown Bloomington to head back to her apartment.
Using surveillance video from the area, police say they've zeroed in on a car that circled the block around the time she vanished. Police plan to enhance the footage to try to determine the driver's identity.
Authorities say they have 10 persons of interest in the case, including Spierer's boyfriend and other people who spent time with her that night. They say they've already taken DNA samples, administered lie detector tests and questioned several people close to the college student.
Police are also investigating whether Spierer was using cocaine prior to her disappearance.
Spierer's Edgemont parents are in Indiana to help hundreds of volunteers in search efforts, and they say they're not giving up hope that she'll turn up alive.
