INDIANAPOLIS (CBSNewYork/AP) — The parents of an Indiana University student missing more than a year hope a tooth from a skull found in the White River in Indianapolis will help quickly determine if it belongs to their daughter.

The skull was found July 8 by a fisherman. Divers searched but found no additional remains. Marion County Deputy Coroner Alfarena Ballew told The Journal News forensic experts will compare the tooth with dental records for Lauren Spierer.

Ballew said authorities want to relieve any stress the family is going through. Spierer went missing June 3, 2011, after a night of partying with friends in Bloomington.

Ballew says other people have called to say it could belong to their missing family members.
