A Dorchester teen already in trouble over a Milton Avenue shooting in May is now staring down a longer list of charges, after a teenage girl was wounded and police say they pulled a loaded Polymer80-style 9mm pistol from a backpack inside a nearby home. The May 6 incident left the girl with non-life-threatening injuries and kicked off a case that has now grown well beyond the original weapons counts.

How police say the arrest unfolded

Around 8:08 p.m. on May 6, Boston officers were called to the area of 129 Milton Ave for a report of a person shot, according to a Boston Police Department news release. Inside a residence at that address, officers say they found several juveniles and a backpack that held a loaded Polymer80-style 9mm semi-automatic pistol. A 14-year-old boy from Dorchester was taken into custody and was expected to be arraigned on firearms charges. The victim, a teenage girl, was taken to a local hospital with non-life-threatening injuries and was expected to recover, a detail also reported by Boston.com.

New charges filed this week

According to WCVB, Boston police now say the juvenile faces a slate of new counts: assault and battery by discharge of a firearm, unlawful possession of a covert or undetectable firearm, unlawful possession of ammunition and unlawful possession of a large-capacity feeding device. The new filings, WCVB reports, followed further review of evidence from the May scene and expand the case beyond the original possession-related allegations.

How this fits a worrying pattern

The Milton Avenue arrest is part of a broader and troubling spring pattern in Dorchester, where officers have repeatedly recovered unfinished or unserialized so-called “ghost” guns and charged juveniles. Neighbors and police have both sounded the alarm as kits and unfinished frames show up in youth-related cases, according to local coverage that includes block rattled as woman shot, two held on Milton Ave and reporting by NBC Boston.

What happens next in juvenile court

Because the suspect is a juvenile, authorities have not released his name, and the case will proceed under Massachusetts juvenile-court confidentiality rules. Those rules generally keep proceedings and records closed to the public unless a judge rules otherwise, according to state court guidance. The teen is expected to appear for arraignment as prosecutors and the court decide how to handle the newly filed counts within the juvenile system.
