The Oregonian interviewed the family of a Portland man shot by Washington County tactical officers last night during an unrelated attempt to serve a warrant—and learned, according to neighbors and family, that he had gone outside to confront someone in dark clothing he thought was a prowler.

Daniel Ibarra told the paper that his stepdad, Alberto Flores, had asked for his gun after seeing someone in the back yard, not realizing it was a police officer.

He said of his dad, "I think he just wanted to scare them away. He didn't know who they were."

Soon after walking outside with his gun, Flores was shot.

Neighbor Juan Soto Martinez, 16, who lives across a walkway from Flores' home, said he heard Flores at his front door yelling with a man, who seemed to be outside, on the side of his house. Then, he heard multiple gunshots.

Ibarra found his stepdad collapsed in the front doorway of their home, shot in one arm and twice in the stomach, and called 9-1-1.

Police haven't officially identified Flores yet but said he was in serious condition this morning. Police last night wouldn't say whether it was officers, or Flores, who fired first. Washington County's tactical team, made up of sheriff's deputies plus officers from the county's various police agencies, was helping Portland officers serve a warrant because Portland's SERT team was training out of town.

The officer-involved shooting is the second in Portland this year—and it raises a vexing issue for the Portland Police Bureau which is investigating the incident even though its officers weren't the ones who fired. As the Mercury reported earlier this year, out-of-town officers accused of improper conduct while working in Portland aren't required to abide by Portland's police oversight rules and face discipline only according to their home agency's policies and training standards.
