Police said they suspect foul play in the disappearance of 26-year-old postal worker Kierra Coles.
Coles, who is three months pregnant, went missing on Oct. 2 after she was captured walking outside of her South Side Chicago neighborhood in her work uniform. She had called out of work that morning, however.
"Based on the length of time of Kierra Coles' disappearance and the fact that she has fallen off the grid, police suspect possible foul play," the Chicago Police Department told The Associated Press. "We continue to get leads and are following up diligently on those leads.”
Coles’ mother called police two days later after she grew worried because she hadn’t heard from her daughter.
Police conducted a welfare check and found Coles’ car parked outside of her home but no sign of the 26-year-old.
"She wouldn't go this long without talking to me," Karen Phillips previously told WLS-TV.
The U.S. Postal Service has offered a $25,000 reward for information leading to finding Coles.
