SALEM – A Peabody carpenter who admitted twice peddling OxyContin to an undercover officer last year to support his drug habit will spend the next four years in state prison before being placed on probation for another four years.Adam Albanese, 33, of 30 Lowell St., made his plea to reduced charges Thursday afternoon in Salem Superior Court to two counts of distribution of an opiate before Judge John T. Lu.The judge agreed to adopt the joint recommendation offered by Assistant District Attorney Karen Hopwood and defense lawyer Joseph F. Collins.Initially Albanese was charged with two counts of trafficking over 14 grams of heroin. His confession to the reduced charges spared him of a mandatory five years in state prison on each of the two drug charges.The charges arise out of two hand-to-hand drug deals with an undercover officer in the spring of 2009.On May 7, Albanese sold 20.1 grams of OxyContin pills to an undercover officer in the Outback Restaurant parking lot on Route 114 in Peabody.Two weeks later on May 20, he sold another 19.7 grams of the illegal tablets to the undercover officer in the McDonald’s parking lot in Danvers.He was then arrested and charged.While on probation, Albanese will be evaluated for substance abuse and treatment as deemed necessary, must consent to random screenings, agree to be drug-free and be employed or have at least two job applications on file.As part of the plea negotiations, the sentence imposed will be simultaneous with another prison term Albanese is now serving on an unrelated matter out of district court.
