Mudslide Leaves 4 Dead, 18 Missing in Washington

A massive mudslide swallowed entire houses, Saturday morning, in Oso, Washington.

Four people have been confirmed dead, eight were injured, and eighteen are still missing.

Mud up to twenty feet deep swept in a sudden rush trapping many people.

Rescue efforts have been hampered by thick, quick sand like mud.

Concerns about the possibility of the Stillaguamish River flooding are also on the minds of officials.
