A rain-soaked hillside collapsed above the north fork of the Stillaguamish River on March 22, unleashing a torrent of mud that swallowed up a stretch of a state highway and some three dozen homes on the outskirts of the tiny community of Oso.
Of the 37 people confirmed dead, 36 have been positively identified, most recently a 14-year-old boy, Snohomish County officials said in a statement. The death toll stood at 36 on Monday.
Recovery crews were still searching for another seven people listed as missing. Their efforts in recent days have benefited from dry weather, a welcome change from periods of rain that have caused treacherous conditions and raised the risk of more slides and flash floods.
President Barack Obama has plans to visit Oso next week to view the disaster site and meet with survivors and grieving relatives of the victims, as well as first responders and recovery workers.
Never miss a local story.
No one has been pulled alive from the rubble since the hours immediately following the mudslide, when at least eight people suffered injuries. Rescue teams have found no signs of life since the day of the disaster.
