The Snohomish County Medical Examiner's Office said the confirmed death toll remained at 39. The three identified were Wyatt Ruthven, 4, Sandra K. Miller, 54, and Ronald P. Dequilettes, 52.
Those still listed as missing by the county Sheriff's Office are Steve and Theresa Harris, 52 and 53, Steven N. Hadaway, 53, and Molly Kristine "Kris" Regelbrugge, 44. All lived in the area in Oso, Washington, buried by the slide March 22.
The body of Christopher Dombrowski, nephew of Theresa and Steve Harris, was found Tuesday in Capitol State Forest, dead in an apparent suicide. Dombrowski, 30, had taken a leave from the U.S. Army to help look for his aunt and uncle.
Scores of people were listed as unaccounted for in the days immediately after the mudslide. The number of dead now appears likely to be 43.
Washington is in the midst of a week of official mourning with flags at state buildings to fly at half-staff until next Tuesday. President Obama is expected to visit the slide area that day for the first time.
