Timothy Warren was driving his FedEx truck through a verdant neighborhood in Portland, Ore., when the man he would soon kill screamed that Warren was going too fast.
Warren stopped his truck. He was exhausted, he tried to explain to Joseph Magnuson that day in late September, and just wanted to get done with his work.
Magnuson was unrelenting and hurled numerous aggressive insults and racist slurs at him.
That was something Warren, who is black, could not abide.
He stepped out of the truck, and both men yelled at each other.
Magnuson took a swing. Warren swung back, connecting a single blow above Magnusons left eye that sent him tumbling to the ground.
Magnuson, 55, briefly lost consciousness, then died later that evening.
Prosecutors, however, have decided not to charge Warren, 41, with a crime. He did not intend to kill Magnuson and acted in self-defense during the Sept. 26 incident, the Multnomah County District Attorneys Office said in a memo released Monday.
Its unclear whether Warren still works for FedEx; a company spokeswoman declined to answer a question about his employment status.
