Corvallis Police arrest biogeochemist on 54 counts of child pornography possession

A 35-year-old Wilsonville man was arrested Monday on multiple counts of child pornography possession, according to a release from Corvallis Police Department.

The investigation initially started on April 13, 2017, when the suspect, Corey Robert Koch, 35, of Wilsonville, had been seen standing outside the window to a home while wearing a black mask. Police say Koch had been peering inside the window at a partially dressed female.

At the time, another person confronted Koch and chased him, detaining him until officers showed up. Koch was arrested at that time on charges of invasion of personal privacy and second-degree criminal trespass.

When Koch was arrested April 13, police seized Koch’s mask and cell phone as evidence.

Police executed search warrants on Koch’s phone, and investigators reportedly located a number of images and videos of unidentified females who had been photographed or recorded without their knowledge, in various states of undress. It is currently not known who the victims are, nor the location where the images had been taken.

Investigators also located thousands of child sex abuse images on the phone, according to police. Koch was contacted at his workplace, Sea-Bird Scientific, where he works as a biogeochemist, by police Monday, Aug. 28, in Philomath, and was arrested on 54 counts of second-degree encouraging child sex abuse.

Koch is held in Benton County Jail on $4,050,000 bail.
