ROGERS COUNTY -- Rogers County deputies are looking for new evidence in a six-year-old murder case.

The sheriff's office is using heavy equipment to clear a path to get to a rural pond in the Northeastern Part of the county near Chelsea. They will then bring in pumps to drain the pond.

Deputies hope to find evidence in the murder case of Robert Sims, who was reported missing in 2004. His body was found near Wiganon in 2008.

"We're looking for types of materials, either rounds or chain, cable things of this nature that may have been used to bound him," said Sheriff Scott Walton, Rogers County.

The search for evidence is expected to take a couple of days. 

Eric Brouse and Charles Kirk are charged with first degree murder in the case.
