Authorities in Indiana are searching a landfill in Terre Haute for clues in the case of a missing Indiana University student.

20-year-old Lauren Spierer has been missing since June 3.

Volunteers have been searching the area near the university for two months.

Tuesday morning, a search centered on a landfill in the town of Pimento, just south of Terre Haute.

Authorities say the search for clues could take two weeks.
