Meri Jane Woods, was convicted yesterday in Pennsylvania.
District Attorney Patrick Dougherty says Woods downloaded 40 images to the family computer, took it to police last August and blamed Matthew Woods for the material.
But when police examined time stamps, they determined the images had been downloaded more than two weeks after Meri Woods had her husband kicked out of their home with a protection-from-abuse order.
Woods' attorney had argued that the time stamps were unreliable.
The Indiana Gazette says Woods faces up to nine years in prison.
