The fire chief in charge of the Washington mudslide rescue operation said crews are facing unreal challenges but have not abandoned hope of finding a miracle survivor. Snohomish County Fire District 21 Chief Travis Hots told reporters as the search entered its sixth day, "My heart is telling me I'm not giving up yet. We're gonna exhaust all options to try to find somebody alive. If we just find one more person that is alive, it’s worth it." There are still 90 names on a list of people who may be missing, and no one has been found alive since the first hours after a 600-foot-high section of hillside collapsed onto the town of Oso.
