On the night of June 18, 2016, 31-year-old Andrew Flonory was walking toward a large party on Astoria Street in Mattapan just before 11:30 p.m. when gunfire erupted. A man inside a fenced area produced a firearm and fired repeatedly at Flonory and another person. Flonory, a Brockton resident and father of five with a sixth child on the way, was fatally wounded; the other person survived after being shot in the shoulder and leg.

The Flonory family had already endured a devastating loss in 2010 when Andrew’s sister Eyanna Flonory, 21, and her two-year-old son Amani were among four people killed in what was called the Mattapan massacre. Andrew reportedly survived a separate murder attempt about a week after that 2010 attack.

In November 2016, Boston police arrested 24-year-old Julian Troche in the Fenway and charged him with Andrew’s murder. Prosecutors said witness statements identified Troche as the shooter and that shell casings and cell phone records placed him at the scene; Troche was also indicted in a separate homicide that occurred five days before his arrest. Did anyone in Mattapan or Brockton who knew Andrew recognize him or have information about that night?
