UMATILLA COUNTY, Ore. (KTVZ) — A yearslong investigation by the Oregon State Police (OSP), in addition to the Fish and Wildlife Division, has resulted in significant penalties for an Umatilla man accused of illegally killing wildlife across Oregon, in what prosecutors describe as one of the most damaging serial poaching cases tied to a single individual.

Christopher George Matson, 48, was sentenced in two separate cases in June following an investigation that began in 2024, when authorities received information he was unlawfully taking big game animals. Matson is a former Oregon Department of Corrections officer.

In February 2025, investigators served a search warrant and seized multiple big game animals and firearms as evidence. In total, 67 criminal charges were referred for prosecution, spanning multiple counties and including allegations such as unlawful take and possession of black bear with the aid of bait, unlawful take of buck deer and antlerless elk, and hunting during prohibited hours. Additional charges included falsely applying for tags, loaning or borrowing big game tags, and unlawful possession of silencers and a short-barreled rifle.

The case was prosecuted by the Oregon Department of Justice’s Wildlife Anti-Poaching Resource Prosecutor.

On June 18, 2026, Matson pleaded guilty in Grant County Circuit Court to seven counts, including unlawful take of buck deer and black bear. He was sentenced to 18 months of probation, a lifetime hunting license revocation, 300 hours of community service, forfeiture of firearms and seized property, and a $52,500 fine payable to the Oregon Department of Fish and Wildlife.

Less than two weeks later, on June 29, Matson pleaded guilty in Umatilla County Circuit Court to additional charges, including unlawful possession of a short-barreled rifle, unlawful possession of a silencer, unlawful possession of multiple wildlife, and unlawful take of mule deer. In that case, he was sentenced to 24 months of probation, a lifetime hunting ban, 300 hours of community service to run concurrently, forfeiture of property, and a $62,000 fine.

Combined, the penalties include probation, a lifetime revocation of hunting privileges, 300 hours of community service and more than $114,000 in fines.

“This is another example of serial poaching which rises to the level of felony conduct based solely on the repeated poaching conduct and impact of one individual on Oregon’s game mammals,” said Jay Hall, the Oregon Department of Justice’s Wildlife Anti-Poaching Resource Prosecutor. “The conduct across the several counties amounts to one of the highest damage amounts done to Oregon wildlife by any singular actor.”

Oregon State Police credited the Washington Department of Fish and Wildlife for assisting with interviews and evidence collection, along with multiple witnesses who came forward during the investigation.
