OSO, Wash. - Three people were killed and several others, including an infant, were injured following a massive mudslide that took out at least six homes near Oso, Washington Saturday morning.

The mudslide, which happened just before 11 a.m., is estimated to be at least 135 feet wide and 180 feet deep, Snohomish County Sheriff's officials said. Authorities believe it was caused by heavy ground saturation from recent rainfall.

The mudslide carried a house with people inside across SR 530, the Washington State Patrol said.

"Initial reports were that a house was stuck in the slide, and someone was calling for help inside," Francis said.

Overall, people have been taken to local hospitals. A 6-month-old infant boy and two other victims are listed as in critical condition, while a 37-year-old man is in serious condition, a hospital spokesperson said.

Officials evacuated nearby residents when slide debris blocked the North Fork of the Stillaguamish River, causing the water level to quickly rise over the bank.
