Landslide death toll rises to 29

(CNN) -- The death toll in last month's massive landslide in rural Washington state has risen to 29, Snohomish County medical examiner's office representative Kelly Stowe said Wednesday.

That count is up one from the previous day.

A rain-saturated hillside along the north fork of the Stillaguamish River gave way on March 22, sending a square-mile rush of wet earth and rock into the outskirts of the town of Oso in Washington's North Cascade Mountains.

Since then, rescuers have trudged through the muck -- 70 feet thick in some places -- looking for bodies, though some cling to hope someone might be found alive even 11 days later.
