The shooting happened at about 7:20 p.m. Police are on the scene looking for shell casings and other evidence.
When officers responded to the shooting, the man was already dead, said Sgt. Christopher Hitas.
"He was walking down the street and he got shot and he ran to a house," he said.
Police blocked off the house and driveway at 54 Lincoln St. as well as closed parts of the street and sidewalk to motorists and pedestrians.
They also were investigating an area across the street, which appeared to be the back of a Springfield Technical Community College building.
Neighbors gathered for a short time around the scene. The shooting happened while people were outside celebrating the holiday weekend.
"We heard three shots and we thought they were M-80's (fireworks)," said Darwin Dawkins, who lives one street over.
Even when police arrived, they thought a child may have gotten hurt from setting off fireworks.
Quentin Foster said he is concerned the killing is a sign the violence is moving closer to his neighborhood.
"Pretty much in this area it is OK. There is more violence down the street," he said.
