For more than four months, people from the parish have gathered there every time a child has been killed by gun violence. Thursday's march was in honor of 15-year-old Percy Rounds, who was killed Monday night in Chicago's West Pullman neighborhood.
Father Pfleger called on state legislators to pass what he called common sense gun laws.
"Nobody should be angry about banning assault weapons in this country. Nobody should be angry with the fact that we want background checks of everybody that buys a gun," he said.
Those who support gun owners' rights say more gun laws will not keep firearms out of the hands of criminals.
