A man accused of killing and dismembering a woman in her suburban home then dumping her remains in a Seattle recycling bin pleaded not guilty Wednesday to murder and theft charges.

A man dismembered a nurse and mother of three in her suburban home then drove her head and other remains to Seattle, where they were found in garbage bags in a recycling bin, authorities said Tuesday.

Seattle police say they believe three body parts — including a foot — found in a homeowner's recycling bin belong to a woman who was reported missing Saturday morning.
