Police investigating the disappearance of an Indiana University student say a pickup truck seen in the area at the time of her disappearance wasn't involved in the case.

Bloomington police Capt. Joe Qualters said Monday that investigators received more than 500 tips after releasing images from security cameras showing a white truck in the area early the morning of June 3, around the time Lauren Spierer (SPEER'-ur) was last seen.

Qualters says police identified the business the truck belonged to and interviewed the owner. He says investigators scoured the vehicle and found no evidence it was tied to the disappearance of the 20-year-old sophomore from Greenburgh, N.Y.

Searchers continue to comb areas outside Bloomington for signs of Spierer, who disappeared following a night of partying with friends.
