A special physical education instructor with ties to the Oregon City School District was arrested on federal child pornography charges on Friday.
James Ian McGlothlin, 39, is charged with one count of producing child pornography.
Investigators seek the public's help to identify possible unknown minor victims. Members of the public who have information that may be relevant to the case are urged to contact the Clackamas County Sheriff's Office tip line at 503-723-4949.
McGlothlin was suspended by the school district on Feb. 16. Prior to that, he worked with a small number of developmentally disabled children as an adaptive physical education instructional assistant. The school district is cooperating fully with law enforcement.
The arrest was the result of an ongoing investigation by the Interagency Child Exploitation Prevention Task Force (INTERCEPT), which includes: U.S. Immigration and Customs Enforcement (ICE); Homeland Security Investigations (HSI); the sheriff's departments of Clackamas and Multnomah counties; and the Oregon State Police.
In addition, the Digital Evidence Cybercrime Unit (DECU), made up of investigators from the Vancouver Police Department and the Clark County Sheriff's Office, has provided substantial assistance with the case.
The prosecution will be handled by the U.S. Attorney's Office for the District of Oregon.
McGlothlin's arrest came two days after Task Force investigators executed a search warrant at his Portland home, seizing laptop computers and other items related to the ongoing investigation, including external hard drives, thumb drives, cell phones, and digital cameras.
According to the affidavit filed in support of the criminal complaint, a forensic examination of McGlothlin's computers revealed sexually explicit images and videos of infants, along with essays where the defendant allegedly discusses drugging and sexually abusing young children.
