LAWRENCE — A Lynn man was sentenced to up to nine years in state prison for his role in running a major drug operation in the Merrimack Valley.
Sterling Guerrero, 25, pleaded guilty Tuesday in Essex Superior Court to possessing a firearm during a felony, possession with intent to distribute fentanyl, trafficking 36 grams of oxycodone, possession with intent to distribute morphine, and illegal possession of ammunition, according to a news release from state Attorney General Maura Healey’s office.
Judge Joshua Wall sentenced Guerrero to seven to nine years in state prison, followed by three years of probation with the conditions that he get and keep a job and not possess weapons or firearms.
In June 2015, Guerrero was arrested in a joint operation involving Massachusetts State Police assigned to the attorney general’s office, the Massachusetts State Police Transportation Drug Unit, the U.S. Drug Enforcement Administration, and the Lawrence Police Department.
During that operation, law enforcement officials seized more than 2,500 grams of fentanyl, more than 900 pills, two guns, and more than $73,000 in cash.
