A year ago, Kierra Coles, a young, pregnant U.S. postal worker, disappeared from her Chicago neighborhood.
Since then there have been desperate pleas for help, but the case remains unsolved, with more questions than answers.
Chicago police, who initially said foul play was suspected, have provided few details and family members and activists hope that the case will not be forgotten, which has happened in numerous cases of people of color.
“If you know something, say something,” Coles’ heartbroken mother, Karen Phillips, told ABC News. “Come forward and say something to end this nightmare.”
