Police now believe foul play is suspected in the disappearance of a pregnant postal worker who has been missing for over two weeks from the South Chicago neighborhood on the South Side.

Kierra Coles, 27, who is three-months pregnant, was last seen leaving her apartment Oct. 2 near 82nd Street and Coles Avenue, according to a missing person alert from Chicago police and the National Association of Letter Carriers.

Her disappearance has led to over $28,000 in reward money being offered for information about her whereabouts and the Thursday announcement from Chicago police that “foul play is suspected.”

Coles was described as a 5-foot-4, 125-pound black woman with brown eyes, black hair and a medium brown complexion, police said. She has a tattoo of a heart on her right hand and one that reads “Lucky Libra” on her back.
