CHICAGO (WTHR) - The family of a pregnant postal worker who was last seen in Chicago nearly four months ago is renewing their push for answers.

Kierra Coles was last seen October 2, walking past her car in her South Side neighborhood while wearing her postal uniform. She disappeared from the view of the surevillance camera and hasn't been seen since.

Coles was three months pregnant when she disappeared. Her mother wants the father of her daughter's unborn child to come forward.

"You still haven't been questioned. If you haven't done anything, then why not?" Karen Phillips told NBC Chicago.

Multiple reward funds have raised over $28,000 for information about Coles' disappearance. Anyone with information is urged to call the Chicago Police Department.
