Three women have gone missing from Chicago’s South Side in recent months — including two who are pregnant, and whose due dates have passed.

According to the Chicago Police Department, Kierra Coles, 27, went missing on Oct. 2 of last year, Marlen Ochoa-Uriostegui, 19, went missing on April 23 this year and Chaunti Bryla, 43, went missing on March 7 this year.

At the time of their disappearances, Coles was three months pregnant and Ochoa-Uriostegui was nine months pregnant, according to police. CBS Chicago reports that Bryla has an 11-year-old son.

Coles was a U.S. Postal Service employee, a Chicago police spokesperson told PEOPLE around the time of her disappearance.

On the day she went missing, she called in sick to work, yet she was captured on surveillance footage that day in her work uniform walking past her car outside her home, the spokesperson said.

Coles is 5 feet 4 inches tall and weighs about 125 lbs, Chicago police said in a missing persons flyer. She is Black with brown eyes and black hair. She has a tattoo of a heart on her right hand and a tattoo on her back that says, “Lucky Libra.”
