Community leaders, activists, and residents gathered for a rally Saturday evening to honor Pastor Reginald Moore.
"We need this cycle of violence to stop," said Chequita Palmer, the pastor's niece. "At the same time, I want the one who did this to pay for it."
Moore was walking to his car after Bible study last Sunday near Compton Boulevard and Dwight Avenue when someone shot and killed him.
