Salt Lake City police and cadaver dogs on Tuesday were taking a break in the search for Lori Hacking's (search) body.

Officials said they've found nothing significant after spending most of the month excavating the Salt Lake County landfill.

Police and dogs spent several hours Monday night digging through 4,600 tons of trash looking for Hacking's body and the murder weapon.

A judge has scheduled a September 23 preliminary hearing for the missing woman's husband, Mark Hacking (search), who is charged with murder.

Officials say the search will be suspended until Friday so the dogs and search teams can rest.
