The Tacoma News Tribune reports (http://bit.ly/QfMKDy ) 42-year-old Alan O'Neill says he's "embarrassed and remorseful."
He was charged in March after his first wife learned of his second wife through a Facebook "people you may know" notification and alerted authorities.
The second woman's profile photo showed her and O'Neill dressed in fancy clothes and standing near a wedding cake.
O'Neill was spared jail time but will be on probation for a year. He has annulled his second marriage and is divorcing his first wife.
His first wife wrote a letter supporting O'Neill, saying the media coverage has been enough punishment.
O'Neill's future as a Pierce County jailer remains in question.
