Searchers Wednesday returned to a site near Kent where confessed Green River serial killer Gary Ridgway said he left a body.
About a dozen law enforcement officers raked along a steep hillside, removing ivy and trash.
They have searched the site a half-dozen times since September, but it covers 5 acres on private property along Lake Fenwick Road.
Even though Ridgway pleaded guilty last week to killing 48 women, most of them in the 1980s, the King County sheriff's Green River Task Force is continuing to look for 4 victims whose bodies have not been found.
Ridgway has been cooperating with authorities as part of the plea agreement that spared him the death penalty.
This is the 52nd search by the task force in the past four months. Remains of 4 people have been found, and 3 Green River victims were identified.
