(Portland, OR) -- A grand jury won't be indicting a man accused of stabbing three people at a Fourth of July party on Government Island. The assault case against Brandon Richard Cullen has been dropped after the grand jury issued a "no-true bill," meaning the panel decided there was insufficient evidence to issue an indictment. The men who were stabbed during a fight at the party suffered multiple wounds, but Cullen told authorities he acted in self-defense. One of the men required surgery on his colon.
