Portland, OR, August 4, 2026 —

A Yamhill County photographer, identified as 59-year-old Robert Koester, has received a 40-year sentence in federal prison. The conviction stems from charges related to the recording and distribution of child sexual abuse material.

According to case details, Koester utilized his photography business as a means to build trust with underage girls. The victims, some as young as 15, were allegedly drugged, abused, and subsequently recorded by Koester.

This federal sentence is set to run concurrently with prior sentences Koester is already serving. He previously received a 25-year sentence in California and a 50-year sentence in Yamhill County.
