At about 10 p.m., before Chief Monahan addressed reporters, a stretch of Baltic Street with the housing complex buildings on either side was blocked off by police tape and vehicles, as officers flooded the block and helicopters buzzed overhead.
Elvis Peguero, the owner of the Los Tios Deli Grocery on Hoyt Street, said he had heard “a lot of shots” — as many as 20, he guessed — just before 8 p.m. in what sounded like volleys coming from both sides of Baltic Street. Within minutes, he said, police officers were swarming the area.
Apartment courtyards on either side of Baltic Street were also taped off, and some residents of the complex said they had been locked out of their buildings with no word on when they would be allowed back inside.
Shortly after 10:30 p.m., a line of officers, some in riot gear and some leading police dogs, walked across a courtyard south of Baltic Street facing the shooting site.
Shanduke McPhatter, a Brooklyn anti-gang activist, said that he personally knew the wounded man, but he declined to offer his name without the family’s consent.
“The family is a family that helps the community,” Mr. McPhatter said. “The family is a family that has been out here mediating conflicts and helping provide resources for this community.”
