A former prison guard pleaded guilty Thursday to charges that he agreed to smuggle OxyContin and a cell phone to a prisoner in exchange for $1,000. 

Dupree Myers, 27, worked at the city’s Curran-Fromhold Correctional Facility. He faces up to 40 years in jail, plus supervised release, a special assessment and possible fine, authorities said Thursday. 

Hes one of six prison guards facing charges in unrelated indictments from within the Philadelphia Prison System.
