Jerrica Laws, 24, hasn't been seen since leaving her house last Monday after going for a walk on the trail behind her home.
Family members say it unusual for them not to hear from Laws.
"We miss her, we just want her home," said Shantinel Laws, Jerrica's sister. "She doesn't go missing, she doesn't. She's a good young lady. I just want her home because we're worried to death about her."
Anyone with information on Jerrica Laws' disappearance is urged to call Park Forest police.
