On the late afternoon of March 15, 2022, 24-year-old Brima Koroma of Boston was found in an East Street neighborhood in Brockton, Massachusetts, suffering from a single gunshot wound to the chest. Emergency responders took him to a local hospital, where he died. The shooting occurred around 4:44 p.m. and generated multiple 911 calls that led to an immediate investigation by Brockton Police and the Massachusetts State Police.

Detectives focused on two people seen leaving the area in separate vehicles. Warrants were issued for 33-year-old Brendan Fernandes of Brockton and 25-year-old Destiny A. Fontes Silie of Warwick, Rhode Island, who had left the state. The next day Virginia State Police stopped a blue sedan in Chesterfield, Virginia, and took Fernandes and Silie into custody; they waived rendition and were returned to Massachusetts.

After return to Brockton, Fernandes was charged with murder, unlawful possession of a firearm, and unlawful possession of ammunition. Silie was charged with accessory after the fact to murder; both pleaded not guilty. Fernandes was ordered held without bail, and Silie remained in custody after bail was revoked on two other open cases. Anyone with information about Brima Koroma or the events that afternoon is asked to come forward.
