KENNEWICK -- An attorney for a Kennewick woman accused of killing a pregnant mother and cutting the baby from her womb said Friday that he may use a mental health defense in the upcoming murder trial.
Phiengchai Sisouvanh Synhavong's defense team may argue insanity or diminished capacity, said attorney Dan Arnold during a hearing in Benton County Superior Court.
"We've been working this case a long time. We're not done yet," he said.
Sisouvanh Synhavong, 25, faces a September trial. She is charged with one count of aggravated first-degree murder in the 2008 death of Araceli Camacho Gomez.
The defendant initially refused to appear in court Friday but was summoned by corrections officers at the judge's request.
The hearing, which lasted about a half hour, also included discussion of questionnaires that will be given to potential jurors.
The next hearing was set for August.
