(AP) — An inmate at the state prison in Pendleton was shot and killed by a guard Friday while fighting in the yard. Withers and another inmate were assaulting a third prisoner in the yard at the Eastern Oregon Correctional Institution, and when they wouldn't stop, a tower guard fired one shot that hit Withers, Primus said. Primus said it was the only shooting at the prison in the six years he has worked in the district attorney's office.
