The employment agency that placed a convicted rapist in a large East Los Angeles county health clinic said that the X-ray technologist's criminal background check came back clear and that he "did not answer truthfully" several questions on his application. Mediscan Staffing Services said it terminated Gariner Beasley, 48, soon after learning of his criminal history. Until recently, Beasley had been working for about a month at the Edward R. Roybal Comprehensive Health Center despite being fired last August by county officials from a similar position.
