LOUISVILLE, KY. (WDRB) -- After a week of searching a landfill for any evidence in the Lauren Spierer disappearance, the Bloomington Police Department says it has nothing new to report.

The Bloomington Police Department has been searching the Sycamore Ridge landfill in Pimento, Ind., just south of Terre Haute.  The FBI, Indiana University Police Dept., and National Center for Missing and Exploited Children are helping in the search, which involves 20-30 people working about 12 hours a day.

The search effort is expected to last another week.  After halting for the weekend, the search will start back up on Monday.

About 500-600 tons of trash has been examined each day of the search.

Bloomington Police say preparations for the landfill search began within days of Spierer's disappearance.  Authorities searched dumpsters in the area where she disappeared immediately after she was reported missing.  The area where waste from the city was taken around the time of Spierer's disappearance has been secured, and no additional waste was allowed to be dumped there.
