The state Supreme Court has upheld the conviction of a Kennewick woman who was sentenced to life in prison for killing a pregnant Pasco mom and cutting her baby out of her womb.

In a unanimous decision Thursday, the high court rejected Phiengchai Sisouvanh's (PEE'-en-chay SIS'-oo-vahn) claim that the court-appointed expert who conducted her evaluation did not properly take into account her cultural background as a Laotian immigrant.

Sisouvanh was convicted of aggravated murder for the 2008 death of 27-year-old Araceli Camacho Gomez. The baby survived and is being raised by his father in Pasco.
