Acute Observations by an Off-Duty Officer Leads to Two Arrests and Firearms Recovered in Mattapan

On Friday, June 5, 2025, officers assigned to District B-3 (Mattapan) arrested Marc Lemene, 20, of Avon, and Manuel Goncalves, 18, of Brockton, on firearm related charges.

At about 11:55 PM, an off-duty officer was leaving the station when he heard over the radio a report of a large fight at 67 Wildwood Street. The officer was passing the area when he observed two suspects and broadcasted a description. One of the suspects made a motion of bringing his hands to the front of his waistband.

As officers arrived on scene, they immediately observed two individuals matching the description. An officer approached one of the suspects and attempted to conduct a pat frisk. The suspect tried to move the officer’s hands away from him and attempted to flee. The officers were able to stop the suspect and felt the handle of a firearm.

A struggle ensued, and the suspect began to resist. The suspect was seen reaching towards his waistband, but officers were able to safely place him into handcuffs. A firearm was recovered from the suspect’s waistband.

Due to the presence of a firearm, the second suspect was placed into handcuffs. After further investigation, a firearm was also recovered from his waistband.
