One Less Gun: Officers Arrest 13-year-old and 23-year-old in Possession of a Firearm during Traffic Stop


At about 11:42 AM on Thursday, December 14, 2017, officers from District C-11 (Dorchester) observed a motor vehicle operating at speeds well above the city’s 25 mile-per-hour speed limit in the area of Waldeck Street. Officers conducted a traffic stop of the vehicle and upon approaching the car, immediately recognized the operator as 23-year-old Keenan Monroe of Dorchester from previous interactions. His front seat passenger (who was not wearing a seatbelt) was identified as a 13-year-old juvenile male, also from Dorchester. A check of Monroe’s information revealed that he was not licensed to drive; therefore, officers removed both occupants from the vehicle and placed Monroe under arrest for Unlicensed Operation of a Motor Vehicle. During an inventory search of the vehicle prior to towing, officers recovered a loaded black and silver Smith & Wesson .40 caliber firearm from a backpack in the back seat. Monroe immediately made statements indicating that the firearm belonged to the juvenile.

Monroe was additionally charged with Unlawful Possession of a Firearm (2nd & Subsequent Offense), Unlawful Possession of Ammunition (2nd & Subsequent Offense), Unlawfully Carrying a Loaded Firearm (2nd & Subsequent Offense), Possession of a Large Capacity Firearm, and Armed Career Criminal Level I. He was issued a citation for his auto law infractions.

The 13-year-old juvenile was arrested and charged with Delinquent to wit; Unlawful Possession of a Firearm, Delinquent to wit; Unlawful Possession of Ammunition, Delinquent to wit; Unlawfully Carrying a Loaded Firearm, and Delinquent to wit; Possession of a Large Capacity Firearm.
