BURIEN, Wash. (AP) — A fast-moving fire gutted an apartment complex in suburban Seattle early Sunday, killing three people, injuring six others and displacing about 50 residents.

The fire started after midnight and left one two-story building gutted and another heavily damaged, King County fire spokesman Dave Nelson said. The cause was under investigation.

"It was horrible," said Melissa Frank, who witnessed the blaze. "The whole building just looked like every corner was on fire."
