TACOMA, Wash. -- The Pierce County Medical Examiner's Office has identified a woman who was fatally shot in front of her 5-year-old daughter outside their home.

The office says 46-year-old Teresa Ryan of Puyallup died in Monday's shooting.

The News Tribune reports 19-year-old Austin Nelson pleaded not guilty to murder and other charges Tuesday. Authorities believe Nelson was upset over "a bad breakup" with the victim's teen daughter, who was not home when the shooting took place.
