A man living in the suburbs of Portland, Oregon, has been found guilty in the 1980 cold case murder of a 19-year-old college student. Robert Plympton, 60, was convicted of first-degree murder in the death of Barbara Mae Tucker by Multnomah County Circuit Judge Amy Baggio.
Although Plympton was not convicted of rape or sexual abuse due to lack of conclusive evidence, a medical examiner determined that Tucker had been sexually assaulted and beaten to death.
