OKLAHOMA CITY (AP) — An Oklahoma pharmacist convicted of murder in the shooting death of a teenager who tried to rob the south Oklahoma City pharmacy where he worked was sentenced to life in prison with the possibility of parole Monday in spite of his defense attorney and supporters' pleas that he be set free. Jerome Ersland, 59, showed no emotion as District Judge Ray Elliott imposed the sentence recommended by a 12-member jury that found Ersland guilty of first-degree murder in the May 19, 2009, shooting death of 16-year-old Antwun Parker during an attempted robbery at the Reliable Discount Pharmacy. Ersland claimed he was defending himself and two female co-workers when he shot Parker after he and a second teenager came into the pharmacy wearing ski masks and demanding money and drugs.
