Casey Zillmer, the Black River Falls man charged three counts of child pornography possession, second-degree sexual assault of a child and child enticement, plead guilty in Jackson County Circuit Court Friday. 15 other charges were read in and dismissed. Judge Anna Becker ordered an investigation before sentencing, which includes a psychosexual examination. Zillmer is being held in the Jackson County jail and is scheduled to be sentenced in July. His wife, Jennifer Zillmer, also faces charges in connection to this case. She is free on bond and expected back in court in May.
