Ronald T. Garney, a 60 year old former Amherst Regional High School science teacher, pleaded innocent to 11 counts of possession of child pornography.  He was originally arrested in November at his Amherst home and charged with three counts of receiving child pornography.  He pleaded innocent to the charges but then was indicted by a superior court grand jury in January.  Eight more counts of possession of child pornography were added after review of his computer and associated media.
