The man who allegedly shot a youth outreach worker in Boston’s South End two months ago was held on high bail at his arraignment today in the Boston Municipal Court, Suffolk County District Attorney Daniel F. Conley announced.

DOMENIC D. HALL (D.O.B. 10/12/83) of Roxbury was held on $250,000 cash bail at his arraignment on charges of armed assault with intent to murder, unlawfully carrying a firearm, and unlawful possession of ammunition. Judge Mark Summerville set his bail at $750,000.

Assistant District Attorney Susan Terrey told the court that Hall fired the shot that struck a 30-year-old street worker in the head on the night of Aug. 21. He was identified as the gunman in the course of an ongoing investigation by Boston Police detectives and senior prosecutors assigned to Conley’s Gang Unit.

“The evidence we’ve developed thus far suggests that this victim was not the intended target,” Conley said. “That said, it’s a miracle he survived. That round could easily have killed him.”

Hall allegedly fired the shot near the intersection of Hammond Street and Shawmut Avenue at about 9:00 p.m. The victim, who was off duty at the time, was rushed to the nearby Boston Medical Center. The gunman fled on foot.

Working with a description of the assailant and additional evidence developed in the hours and days that followed, investigators identified Hall as a suspect and undertook a search for him. Yesterday morning, members of the Boston Police Fugitive Apprehension Unit and US Marshals took him into custody at a Mattapan residence.

“Street workers are out there every night trying to keep kids out of trouble and defuse conflicts before they turn violent,” Conley said. “We received a lot of cooperation from witnesses in this case, and I think that’s a testament to the respect that outreach workers have earned.”

Jessica Sheehan is the victim-witness advocate assigned to the case.
