PORTLAND, Ore. (AP) — In December 2017, a Portland man knocked at the door of a pub and collapsed, bleeding from a stab wound in his back. In his last few moments, court documents say, Brian Nees told police officers as they arrived that his son had stabbed him.

Tyler Nees was convicted Thursday of murdering his father. A jury unanimously found Nees guilty of murder constituting domestic violence and unlawful use of a weapon.

KOIN News reported that in closing arguments, Tyler Nees told the judge that his brother killed their father. But documents show that DNA evidence, as well as 911 calls, pointed to Tyler Nees. Nees acted as his own attorney, had previously had several attorneys in the case and threatened to kill one of them.

Nees initially fled the scene after the stabbing and was arrested nearly two weeks later.

Court documents describe the stabbing, and the actions leading up to it, as the culmination of family conflict.

Nees is set to be sentenced in March.
