The family of Kierra Coles is still searching for answers after the 26-year-old pregnant letter carrier disappeared in October 2018 in Chicago.

According to WLS-TV, family and friends have increased the reward for information leading to Coles from $45,000 to $63,000. At a March 7 vigil in Chicago, Coles’ mother Karen Phillips said, "Can't nobody imagine to pain that I go through daily. Missing my child, not hearing her voice, not knowing if she had her child. Not knowing if she's suffering every day."

Coles, who was three months pregnant at the time of her disappearance, was last seen on the night of Oct. 2, 2018. Her family said they found her car parked on her block, with her cell phone and purse still inside.

On the day she went missing, Coles called in sick from work and a surveillance video captured her walking up and down the street the morning she vanished, PEOPLE reported.

In October 2018, Dan Perkins, the boyfriend of Coles’ mother, told WGN that Coles walked past her car, as if she saw something. “She seen something that made her turn around that fast and cross the street, and her car was on the other side of the street,” Perkins said.

Days went by and when her family tried to call Coles, her phone went straight to voicemail. Officers then went to her apartment to conduct a welfare check. Inside her unit, officers found Coles’ wallet and keys.

No arrests have been made.

WLS-TV reports Coles is described as 5 feet, 4 inches tall, 125 pounds. She has a tattoo of a heart on her right hand and another tattoo that reads “Lucky Libra” on her back. Anyone with information is asked to call police at 312-747-8274 or dial 911.
