Vaughn was beaten to death in Chicago's Englewood community. His mother says there is a way to stop the violence.
"We need help. Not just parents; we need the city. [We need] other parents to come help out. It takes a village to raise a child. They took it from us. We've got to get it back," Yolanda Johnson said.
Nathaniel Tucker, 23, has been charged in Vaughn's murder.
