A convicted rapist fired in August from his job as a Los Angeles County hospital X-ray technologist was rehired by county managers through a contractor a short time later to do the same work at an East Los Angeles health clinic, officials acknowledged. Gariner Beasley, 48, was fired again Tuesday and escorted from the Edward R. Roybal Comprehensive Health Center, said county Supervisor Gloria Molina. County officials struggled to explain how they had rehired a man they fired in August, calling his criminal record incompatible with a job that required he work alone with patients in "very vulnerable and compromised positions."
