Police searching for a missing Indiana University student say an enhancement of security video from the area where she was last seen could help investigators identify one or two vehicles that appear in the footage.

Bloomington police Capt. Joe Qualters said Monday an ongoing enhancement aims to determine the make of the vehicles captured by the video. He says investigators haven't "made a leap" into believing the vehicle's driver played a role in the June 3 disappearance of 20-year-old Lauren Spierer from Greenburgh, N.Y., who vanished after a night of drinking with friends.

But Qualters says if it's determined the two vehicles seen in the footage are the same one then investigators will be "curious" whether the driver was circling the area and might be involved in Spierer's disappearance.
