KENNEWICK, Wash. (AP) — A 48-year-old shooting victim remained in critical condition after he was shot outside a Plymouth home in Benton County. The shooter then turned the gun on himself. The man died but Benton County sheriff’s investigators were still trying to confirm his identity Tuesday. Sheriff’s detectives are investigating the shooting at 4:30 p.m. Monday. It happened on Christy Road in the rural Benton County town close to the Columbia River near the Oregon border. Officials say initial reports were that the men were arguing outside one of the homes. One man opened fire and hit the 48-year-old man before running off.
