The case of a former Northeast Ohio school employee who allegedly obtained several images of child pornography has made its way to federal court.

Thirty-six-year-old Massillon native Andrew Shonk, who worked a combined 12 years at both Rootstown Local and Hudson City Schools, was indicted Wednesday on charges of receiving and possessing viral depictions of minors engaged in sexually explicit conduct, the U.S. Attorney's Office announced. Prosecutors say he collected the files during a nearly five-year period beginning in March of 2013.

Shonk worked as a technology specialist at the Portage County Educational Service Center (ESC) between 2006 to 2012 and was assigned to Rootstown before being hired by Hudson in 2013. According to the district, some of the images involved were of Rootstown students.

"The Rootstown Local School District is cooperating with federal authorities in a criminal investigation concerning Mr. Shonk," Superintendent Andrew Hawkins told parents at the time of the arrest last week. "Safety of our students and staff is always our primary concern and we will continue to work closely with law enforcement throughout the investigation and prosecution."

Prior to the indictment, Shonk was being held on $500,000 bond in the Stark County Jail. Hudson City Schools also placed him on administrative leave, prompting his resignation from the district. The FBI says Shonk did not possess any sexually explicit photos of Hudson students.

"He did, however, seek and save photographs from social media sites, and the FBI has indicated some of those social media photos are of Hudson students," Superintendent Phil Herman said. "We do not yet know from the FBI specifics on what sites he accessed."

The case against Shonk was investigated by both the Canton and Jackson Township Police Departments, as well as the FBI.
