The boy, identified Wednesday morning as Daniel Pearson, was pronounced dead at a local hospital at 8:22 p.m., according to Detective Vernon Davis, a police spokesman. The two other victims, men ages 33 and 20, were also sent to hospitals and were in stable condition Wednesday morning, police said. Police did not identify the victims.
Local residents gathered in small groups along Greenmount after the incident said the shooting sounded like it occurred in scattered bursts in different parts of the neighborhood.
"It sounded like the wild, wild west," said Tamm Hunt, a local jazz singer who said she's been trying to transform the neighborhood into an arts community.
Homicide detectives on the scene took pictures and put down evidence markers outside of the Byrd Land Carry Out on Greenmount. Just down the road, police tape blocked off the street at E. 27th Street, where a black and white sign read, "Warning: 24 Hour Video Surveillance Area."
New Police Commissioner Anthony W. Batts also visited the scene to speak with detectives, Davis said.
A block away, on Boone Street, another crime scene had been blocked off with police tape, as detectives walked up and down the block interviewing people.
Police had no suspects or motive in the shootings as of Wednesday morning, Davis said.
Hunt stood nearby with a longtime neighborhood resident who didn't want to be named and Ben Graham-Putter, one of the young founders of Brickhaus Art Space, an artists' studio that offers community art seminars.
"We're just standing here trying to figure out how we can clean up our block, to make it a safer community," Hunt said. "We want to take these vacant lots and turn them into sculpture gardens."
Graham-Putter, 24, said he and others involved with Brickhaus are "very invested in the community," and are hoping art programs will help keep local kids away from the city's violence.
"We're very interested in having, and committed to having, programs for the people who live here," he said.
Eight of this year's murder victims were under the age of 18. That continues a downward trend in youth violence, after 27 or more juveniles were slain between 2006 and 2008. Last year, 13 juveniles were killed.
However, statistics also show that the number of victims ages 18 and 19 have ticked upward, representing more than 10 percent of this year's victims, compared with 5 percent last year.
About 3:15 p.m. Tuesday, police responded to Johns Hopkins Hospital for a report of a walk-in shooting victim and found a man with a gunshot wound to the left leg. Police determined the man had been shot in the 2800 block of Orleans Street in the McElderry Park neighborhood in Southeast Baltimore.
About an hour before that, about 2:15 p.m., police were called to the 5600 block of Frankford Road, in the Frankford neighborhood of Northeast Baltimore. Police said a man was shot in the arm.
At the scene, police taped off a home where a sweat shirt on a front stoop was collected for evidence, while a driveway across the street leading to apartment buildings was also blocked off amid heavy after-school traffic on Frankford Road.
