Organizers with the group Peaceaholics press for city funds to stop gang violence at the scene of Saturday's shooting.
Police are blaming the shooting, which also injured other three people, on gang violence.
Hours before Terry Jiminez was arraigned in court on murder charges, Ron Moten and other organizers with the gang-prevention group the Peaceaholics were out at the scene of the shooting, criticizing city officials for cutting the organization's budget.
"We want to come together and do what we teach these children do: Put aside your differences and do what's best for our community," Moten says.
D.C. Police Chief Cathy Lanier says she welcomes anyone who wants to help prevent gang violence.
"If others want to jump in volunteer to help us out, we would be happy to have them," says Lanier.
But when pressed if these groups should be paid for their efforts, she declined to answer.
