Joint Investigation Leads to Four Arrests, Seizure of About 750 Grams of Fentanyl in Lawrence

Early yesterday morning Massachusetts State Police Troopers assigned to the Commonwealth Interstate Narcotics Reduction Enforcement Team (CINRET), working in conjunction with the State Police Troop A Community Action Team, the state Attorney General’s Office, and the Drug Enforcement Administration, concluded a months-long investigation into a Lawrence-based drug trafficking organization by making four arrests and seizing several hundred grams of fentanyl.

The joint investigation, over the last several weeks, identified runners, accomplices, and a possible stash house at 10 Kempton Court in Lawrence. Troopers and officers established surveillance Tuesday evening and observed a narcotics transaction. Following the suspected transaction, an MSP patrol Trooper conducted a motor vehicle stop of two targets and placed them under arrest. Further investigation led to a search warrant for the Kempton Court address. As a result of the warrant execution, one additional suspect was placed under arrest at the Kempton Court residence and police seized a large quantity of fentanyl, several finger presses, and $1,060 in currency. The total amount of fentanyl seized during the course of the investigation was approximately 750 grams. A fourth defendant was placed under arrest at a separate location.

The four arrestees were booked on trafficking charges at the State Police-Andover Barracks and arraigned yesterday by the Attorney General’s Office in Lawrence District Court and were ordered held on high bails.

They are identified as: ALEX MARTINEZ, 32, a male from Lawrence; JEAN CARLOS MARTE-VELASQUEZ, 27, a male from Lawrence; GENESIS FERNANDEZ, 26, a female from Lawrence; and SERVINO PEREZ-GUZMAN, 29, a male from Lawrence.
