(CBS) – The marchers who blocked traffic on the Magnificent Mile Thursday hoped for a more peaceful 2016.

They walked up and down Michigan Avenue, in an effort to draw attention to gun violence.

Next week, Pam Bosley will visit a head stone rather than celebrate with her son on his birthday. Terrell Bosley would have turned 28 Tuesday. He was shot and killed back in 2006.

“The joy of living is gone. You don’t have a desire to live, but you just go day by day,” Pam Bosley says.

Marchers, who included Father Michael Pfleger and the Rev. Jesse Jackson Sr., say they hope the pace of killing slows in the weeks and months to come.

Some in the demonstration renewed calls for Mayor Rahm Emanuel to resign, in the wake of the officer-involved shooting of black teen Laquan McDonald. Pfleger noted Thursday’s march was more about the violence in general in Chicago, where 442 were killed in 2015.

“That’s worse than a war zone,” he said.
