(Portland, OR) -- Authorities are releasing the identity of four police officers who shot and killed a man in Portland's Hazelwood neighborhood earlier this month. The Portland Police Bureau identified the officers yesterday as Officers Dewey Madison, Sebastian Precup and Jake Ramsey and Sergeant Justin Thurman. The bureau says the officers were serving a search warrant for 45-year-old Richard Shawn Perez at a home on Southeast 124th Avenue on May 6th when Perez allegedly opened fire on them. That's when officers returned fire, killing him. The four officers involved in the shooting were placed on paid administrative leave, which is standard police procedure following an officer-involved shooting.
