Stacy Coleman, 33, was shot and killed during an outdoor gathering on Danube Street in Dorchester on a Sunday evening. Prosecutors say an altercation between Coleman and 35-year-old Ira Grayson of Manchester, New Hampshire, escalated to gunfire around 8:30 p.m.; officers found Coleman with a gunshot wound to the chest and he later died at a local hospital.

Grayson reportedly admitted himself to a hospital with a non-life-threatening gunshot wound to the arm and was arrested there the following Monday morning; police allege he was in possession of illicit drugs at the time. Prosecutors charged Grayson with murder, unlawful possession of a firearm, and drug-related offenses, and he was ordered held without bail at his first appearance in Roxbury Division of Boston Municipal Court. His next scheduled court date was set for August 20.

Does anyone have information about Coleman, the gathering on Danube Street, or witnesses to the altercation that night?
