Mark Saltzer, who was arraigned Monday on 10 counts of felony sexual exploitation of a child, is being held on $1 million bond at the Ada County Jail.
The 45-year-old Boise man has worked as a counselor at Meridian Middle School. He is now on administrative leave, according to the Meridian School District.
Saltzer has been a counselor with the Meridian School District since 2007, according to district spokesman Eric Exline. He said the district has fielded only a few calls from concerned parents.
"In terms of the investigation, it has taken place completely outside our school system," Exline said. "We were not part of it."
Ada County Deputy Prosecutor John Dinger told a judge Monday that Saltzer should be held on $1.5 million bond because of the serious nature of the his crimes, including production of child pornography.
"In his interview by the detective, he admitted that he had produced child porn in the past," Dinger told the Statesman Monday afternoon.
Police got a warrant Friday night, searched Saltzer's Boise home 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.
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.
Other than the teen at Saltzer's house, Dinger knew of no others who had come forward or been identified as sexual abuse victims.
Saltzer was arrested and booked into the jail early Saturday morning. A preliminary hearing is set for Sept. 10.
