Kierra Coles would have turned 32 this year.
She went missing nearly six years ago in Chatham, at 81st Street and Vernon Avenue.
"I want my daughter home. It's a struggle getting up every day without my child, knowing where she's at. Is she safe?" one family member said.
Coles was three months pregnant when she disappeared.
A few years ago, police released video of her visiting an ATM. That was her last known movement.
The U.S. Postal Inspection service is offering a $25,000 reward in the case.
