Questions have been raised after it was learned there were reports years ago warning of the potential for catastrophic landslides in the area.
The search for victims is in its sixth day at the site where hope of finding survivors has been replaced with the realization that some families may not even have someone to bury.
Search crews have located 25 bodies in the debris field but have only managed to recover 16 of them.
The Snohomish (snoh-HOH'-mish) County emergency management director says 90 people are confirmed missing. In addition, there are 35 people who may or may not have been in the area at the time of the slide.
