The case against Larry and Carri Williams of Sedro-Woolley went to the jury Friday in Mount Vernon.
The two also are charged with manslaughter in the death of Hana Williams in the backyard of the family home in May 2011. The girl died of hypothermia and malnutrition. Prosecutors say she was starved, beaten and forced outside as punishment.
Larry and Carri Williams also are charged with first-degree child assault, for allegedly abusing their son who also was adopted in 2008 from Ethiopia.
They have pleaded not guilty to all charges. Defense lawyers told jurors that questionable parenting practices don't necessarily amount to a crime.
