An Oregon man will spend the next 25 years in prison after pleading guilty to stabbing a romantic rival through the heart in an attack prosecutors described as motivated by jealousy. Eliazar Martinez-Rodriguez, 35, was sentenced for the June 2024 killing of 30-year-old Jefferson Cates in Oregon City, a case that unraveled when Martinez-Rodriguez discovered Cates was seeing the same woman he was courting.
Background
The conflict centered on a love triangle at the Crown Court apartments on Southeast 97th Avenue in Oregon City. According to the Clackamas County District Attorney's Office, Martinez-Rodriguez had been romantically involved with a woman living at the complex but was unaware she had also been intimate with Cates. When Martinez-Rodriguez learned of the connection, he allegedly became enraged.
On June 22, 2024, the woman and Cates returned to her apartment and encountered Martinez-Rodriguez. Prosecutors state that Cates was unnerved by Martinez-Rodriguez's behavior and walked away. However, Martinez-Rodriguez later located Cates elsewhere in the apartment complex and launched a violent attack. Witnesses reported hearing a "blood-curdling scream" as Cates was stabbed in the heart.
The investigation revealed a troubling pattern of prior legal issues for the suspect. At the time of the killing, Martinez-Rodriguez was on supervised release from federal prison following a firearms conviction. He had violated the terms of his release by leaving the Northwest Regional Re-Entry Center in Portland, where he was ordered to reside. Although he was arrested and returned to federal court, a judge allowed him to remain out of custody and return to the re-entry center. It was only a month after this decision that Cates was killed.
The Charges
Martinez-Rodriguez pleaded guilty to first-degree manslaughter for the homicide and second-degree assault for a separate incident that occurred while he was in custody. The assault charge stems from an unprovoked attack on another inmate at the Clackamas County Jail in May. The District Attorney's Office reported that Martinez-Rodriguez struck the prisoner with a "barrage of 50 or 60 punches to the head and face," leaving the victim flat on his back with a bloody face and struggling to breathe. The injured inmate survived after being transported to a hospital by ambulance.
During the sentencing hearing, Cates' mother, Lynette Brunson, delivered an emotional statement. "I carry Jefferson's ashes with me every day, but you carry his blood on your hands," Brunson said. She described suffering from recurring nightmares, high blood pressure, and takotsubo cardiomyopathy, known as "broken-heart syndrome," as a direct result of her son's violent death. Brunson also criticized the federal judge's earlier decision to let Martinez-Rodriguez remain out of custody, stating the choice "literally haunts" her.

What's Next
