According to the Pioneer Press Arturo Macarro Gutierrez was convicted of four counts of criminal sexual conduct following a four-day trial in Ramsey County District Court, Minnesota

The mom took her daughters to the hospital, and they tested positive for gonorrhea.

Police arrested him after SWAT executed a search warrant at his home and found him hiding in the attic.
