Beginning at about 5:05 PM on Sunday, May 17, 2015, officers from District B-3 (Mattapan) responded three separate times to radio calls for a group fighting in the area of 845-849 Blue Hill Avenue.
After twice restoring peace in the above area, officers received a radio call at about 6:50 PM for a person with a gun. As officers approached the scene, they observed a group on the sidewalk move quickly up the front steps and into the building. Officers entered the open door and gave chase to the group of fleeing males who matched the suspects’ descriptions. The officers pursued the suspects to the second floor, through an apartment to an open door leading to the back stairwell. The officers followed the sound of running footsteps down the stairs and out the back door where they observed a young male panting and sweating heavily near the bottom of the steps. The officers observed that the male was attempting to conceal a blue backpack behind his feet. Despite the suspect adamantly denying ownership of the bag, officers frisked the backpack and felt what appeared to be a firearm inside. A search of the bag revealed one loaded black Thompson Super 14 rifle and one loaded black and brown Smith & Wesson 357 firearm.
Upon discovery of the firearms, officers held all parties on scene for further investigation. Review of surveillance video showed the above 15-year-old juvenile suspect carrying the blue backpack while other parties put items in or removed items from the bag. After viewing the video, receiving witness statements, and through officer observations, officers brought four individuals to the district station for interviews.
Further investigation led officers to arrest the above 15-year-old juvenile male from Dorchester for Delinquent to wit: Unlawful Possession of a Firearm (2 counts), Unlawful Possession of Ammunition, and Carrying a Loaded Firearm on a Public Way (two counts).
A second 15-year-old juvenile male of Dorchester was arrested for Delinquent to wit: Assault by Means of a Dangerous Weapon (Gun), Threats, Unlawful Possession of a Firearm (two counts), Unlawful Possession of Ammunition, and Carrying a Loaded Firearm on a Public Way (two counts).
Nineteen-year-old Christian M. Brown of Dorchester was arrested and charged with Unlawful Possession of a Firearm, Unlawful Possession of Ammunition, and Carrying a Loaded Firearm on a Public Way.
A fourth individual was identified and released.
