Cheryl Parks, a mother of two young children and a prep cook in the Morehouse College cafeteria, was 33 years old when she went missing...

Parks was last seen the evening of January 10, 1992. She called her younger sister as she left work for the day. Angela Broughton still gets emotional when she thinks about their final conversation.

"She got off work and called and told me she wasn't coming home, that she was going to spend the night with her boyfriend," Broughton told 11Alive's Blayne Alexander. "And I said, ok. Be careful."

The next morning, Broughton said her sister's boyfriend told them that she had left his house to attend a party.

After that, the trail just stopped.

"The detective said they suspected foul play, but they didn't have a body," Broughton said, her voice trailing off.
