Man pleads not guilty to slashing stepdaughter's throat

SHELTON, Wash. -- A man who prosecutors say slit his 5-year-old stepdaughter's throat with a kitchen knife pleaded not guilty on Monday.

Peter James Wilson, 29, has been charged with first-degree murder in the June 27 killing of Clare Louise Shelswell.

During his arraignment in Mason County Superior Court, Wilson was handcuffed and wearing a bullet-proof vest. His said nothing and kept his eyes down through the short hearing.

Wilson allegedly admitted to detectives that he killed the girl during a dispute with his wife at a house near Lake Cushman.

According to court documents, Wilson and his wife were arguing about child discipline when he told his wife not to worry and that he would "take care of it."

Wilson took the girl downstairs and his wife ran after them when she heard screaming. She told investigators that she ran into the room and saw her daughter in a pool of blood clutching her throat.

The family is from Abbotsford, British Columbia and was vacationing at the home at the time of the killing, investigators said.

Officials said Wilson told investigators that he has bipolar disorder and is taking medication for his condition.
