Man sentenced for killing co-worker because he believed he had been intimate with his girlfriend

OREGON CITY, Ore. (TCN) — A man and his girlfriend, both 27, will spend time behind bars for killing a 25-year-old man in what prosecutors said was “an act fueled by jealousy.”

In a news release posted April 14, the Clackamas County District Attorney’s Office said Cody Denewith pleaded guilty to first-degree manslaughter and first-degree assault with a firearm in connection with the death of Nathan Anderson, his former co-worker. He was subsequently sentenced to 240 months in prison for manslaughter and 90 months for assault. He will serve 27 1/2 years, but prosecutors said a “provision allows him to earn credit that could slightly reduce his term.”

Denewith’s girlfriend, Dominique Britt, previously pleaded guilty in December to first-degree manslaughter and unlawful use of a weapon, and she received a sentence of 150 months in prison.

According to the district attorney’s office, on April 29, 2024, Denewith shot Anderson in the abdomen three times. Anderson was transported to a hospital and pronounced deceased upon his arrival.

Denewith reportedly believed Anderson, whom he had worked with at Dave’s Killer Bread, had been “sexually intimate” with Britt.

Days before the fatal shooting, police responded to Britt and Denewith’s apartment for a domestic call and arrested Denewith. While Denewith was in jail, Britt allegedly claimed Anderson had sexually assaulted her. Prosecutors said Denewith became “consumed by the belief that it had happened” and “fixated” on killing the victim.

On the day of the fatal shooting, Denewith reportedly sent his girlfriend a text message asking her to “pack him clothing and his ‘toy’ from upstairs,” which was their code work for a Sig Sauer P365 handgun. According to the district attorney’s office, Britt told later officials she did as her boyfriend asked and gave him the gun knowing Denewith planned to shoot and kill Anderson.

Denewith and Britt were initially charged with second-degree murder. Prosecutors noted that Denewith was previously convicted in 2022 of felon in possession of a firearm out of Clatsop County and convicted of burglary in Oklahoma in 2016.
