"This is what we do, we come together," she said. "You won't find another neighborhood like Dorchester in the whole world."
"Evil lives in this world but good will always overcome it," Eames added.
Joyce Allen and her daughter, Faith, said they couldn't believe the news about Martin's death when they first heard it.
"When they announced it, I was like, 'Is it this Martin?' and then I saw the last name and I thought it was very sad and how the family's going cope with that?" Joyce Allen said.
A few miles away from Dorchester, another vigil was held in Boston Commons Tuesday night where several hundreds gathered to remember Martin and the other two fatalities from the attack.
Krystle Campbell, 29, was identified Tuesday as the other fatality in the attack.
Campbell's parents, William Campbell Jr. and Patty Campbell, at first thought their daughter's friend had been killed, but later learned that it was their daughter who was the victim, according to ABC News' Boston affiliate WCVB.
The parents discovered their daughter was the one who had died when they were finally allowed to see the patient who had survived.
"I said, 'That's not my daughter. That's Karen! Where's my daughter?'" Patty Campbell told WCVB.
