Last week police released a picture and description of the truck which was seen circling around a city block in the area when 20-year-old Spierer was last seen walking alone toward her apartment around 4:30 a.m. June 3.

After receiving almost 500 tips, investigators located the driver of the vehicle who was closely scrutinized and eventually eliminated from consideration as a suspect, police say.

This weekend turned up no new information on the missing 20-year-old despite energetic search efforts. A tip of a suspicious odor led police, search crews, an evidence tech and a helicopter to a wooded area south of Martinsville just off State Road 37, but proved to be another dead end, reports CBS affiliate WISH-TV.

Police also said that a bag of clothing taken from Spierer's apartment building Friday morning had no connection to the case.

Spierer, of Greenburgh, N.Y., went missing in Bloomington more than weeks ago, after a night out partying with friends.
