A jury trial for a 43-year-old former Meridian Middle School counselor accused of producing child pornography is now set to begin on April 3.

Mark Saltzer, who was arrested in August and is being held in the Ada County Jail on a $1 million bond, pleaded not guilty Tuesday to 10 counts of felony sexual exploitation of a child.

The 45-year-old Saltzer worked as a counselor with the Meridian School District since 2007 until he was put on leave late this past summer, according to Meridian School District records. Saltzer no longer works for the school district.

Meridian School District spokesman Eric Exline said in August that any crimes committed by Saltzer took place “completely outside our school system ... We were not part of it."

Ada County prosecutors say Saltzer admitted to police that he produced child porn in the past.

Police searched Saltzer's Boise home the night of Aug. 17 and quickly found 390 pornographic images of children — the majority were boys ages 7 to teens, but there were some images of young females, including one 18-month-old. Saltzer had multiple encrypted computers.

Ada County Deputy Prosecutor John Dinger said at the time the warrant was served, a teenage male was at Saltzer's house. The 17-year-old told police that he had been sexually abused by Saltzer.

Boise Police assisted in the arrest, but the 10 counts of sexual exploitation are the result of a federal investigation. Saltzer was part of an online group that trades self-produced porn files, Dinger said.

It is unclear if police or prosecutors have identified any other possible victims in the case. No new charges have been filed against Saltzer since his arrest in August.

The crime of sexual exploitation of a child is punishable by up to 30 years in prison for each charge.
