Man Charged with Dozens of Sexual Assault Counts in Oregon and California

FBI and Local Law Enforcement Partners Are Seeking Models Photographed and Potentially Victimized by Robert Arnold Koester

The Federal Bureau of Investigation (FBI), Yamhill County (Oregon) Sheriff’s Office, and the Carlsbad (California) Police Department are asking for the public’s assistance in identifying potential victims of a suspected serial sexual predator who took nude photos of models and is alleged to have sexually assaulted many of these models, including individuals younger than 18 years of age. Robert Arnold Koester—also known as Bert Kay, Rhake Winter, and Qitooly—age 52, has potentially been engaging in these criminal acts starting in 1994 and continuing through his initial arrest in Carlsbad, California, on November 13, 2018.

Alleged victims have been identified in multiple cities across the United States. At the time of his arrest, Koester worked as a professional photographer, engaged in the photography of models, primarily on the West Coast of the United States.

At the time of his initial arrest in November 2018 by the Carlsbad Police Department, Koester was living in Southern California. He currently faces 23 felony charges filed by state prosecutors in San Diego County related to that arrest, including child sexual abuse and production of child pornography.
