CHICAGO —Three women, two who are pregnant, are missing from Chicago’s South Side, and their families are demanding answers.

Kierra Coles’ family made an emotional plea for someone to come forward with information about her case Sunday, as they try to breathe new life into the search for the missing postal worker.

Coles’ friends and family passed out flyers near her home at 81st Street and Vernon Avenue Sunday, as the reward for information on her case has been increased to more than $46,000. They were joined by the families of two other women who are missing from the South Side, including a 19-year-old Pilsen woman who was also pregnant when she went missing.

“Our young women are going missing without a trace,” community activist Andrew Holmes said.

The last time Coles was seen was on a surveillance video recorded in October, which shows the pregnant 27-year-old postal worker leaving her South Side apartment dressed in her uniform, despite calling in sick to work, and walking past her car.

Coles’ due date was April 23, but the fate of her and her child are unknown.

“We hope someone can bring her home in one piece her and her baby. I just don’t want my sister gone forever,” sister Kianna Coles said.

Similarly, 19-year-old Marlen Ochoa-Uriostegui was pregnant when she went missing after leaving Latino Youth High School in Pilsen on April 23.

The family of 43-year-old Chaunti Bryla, including her aunt and 11-year-old son, are also desperate for answers. She has been missing since March 15th, and was last seen near her home at 85th Street and and Bennett Avenue.

“Every day you think about it, every day and night,” Bryla’s aunt Eileen Sterling Ross said. “It’s just tough.”

With an $18,000 increase in reward money Sunday thanks to a donation from a local business, there is hope someone with information will come forward.

“We’re not going to go quiet, we’re not going to let this rest,” said Mack Julian, president of U.S. Postal Service Branch 11. “We’re not going to allow this to become a cold case.”
