More than 100 marched through downtown Portland on Saturday to protest the death of Patrick Kimmons, who was fatally shot by police officers last Sunday.

The group, which included members of Kimmons' family, gathered near a memorial supporters have set up near Southwest 4th Avenue and Harvey Milk Street, at the parking lot where the shooting occurred.

They marched to the downtown Justice Center, where speakers, including relatives of Kimmons, demanded police accountability in the shooting.

"We're not here to riot. We're here for justice," said Charles Kimmons, a family member. "We need to fight this all the way to the end. These cops need to be locked up."

The group then marched back to the parking lot where the protest began, where they blocked Southwest Fourth Avenue but directed traffic around the demonstration.

Protesters mixed with traffic, mostly without incident, but reporters for Oregon Public Broadcasting and KATU-TV said a driver struck a protester near the Justice Center and drove away. The protester was not seriously injured.

Police presence was minimal. Officers were seen monitoring the protest from a block away.

Kimmons was shot shortly after 3 a.m. Sept. 30, when the Portland Police Bureau said Sgt. Garry Britt and Officer Jeffrey Livingston heard gunshots from inside their vehicles, parked near.

At the other end of the lot nearer to Southwest Third Avenue, there was a fight and a shooting, leaving two men wounded. Police then saw Kimmons turn toward them or head their way holding a gun, sources told The Oregonian/OregonLive.

The officers yelled commands and fired at Kimmons with their handguns, striking him in the upper torso and leg. Between the sergeant and officer, 10 to 12 shots were fired.

Police are awaiting forensic analyses from the state crime lab on a revolver found near Kimmons and four other guns recovered at the scene, but suspect Kimmons shot the two other men at the scene, the sources said.

Police officials have said little publicly about the circumstances of the shooting, despite pleas from Kimmons' family and other supporters.

Save for a one man yelling at protesters who just left, things are quiet. Protesters are blocking SW Fourth Ave. at Harvey Milk. Police are monitoring from a block away. pic.twitter.com/MoAurW2o0I — Elliot Njus 🏠🏢🏗 (@enjus) October 7, 2018
